UPS Battery Replacement

02 Feb

An un-interruptable power supply (UPS) provides battery power for your computer when the main grid fails. During a “power anomaly,” these relatively inexpensive devices keep the computer running for about 10 to 12 minutes — giving enough time to save your work and DELL Studio 1535 battery shut down. If you are not at home, included software can gracefully shut down the computer.

The real reason for a UPS is to protect the hard disk from brownouts and power surges. Power gremlins like these can fry a computer’s motherboard but a bigger fear is corrupting the hard disk — which would ruin everything. As always, data is more valuable than hardware.

For these reasons, I’ve always used a UPS on my main computer. But recent events showed my old UPS was tired and I was forced to fix it.

My UPS is Pooped-out:

My (six) year old APC cs350 UPS has been slowly dying. The unit has a sealed, lead-acid rechargeable battery and like a car battery, it can lose its punch. When it was new, it ran the computer Dell Studio 1735 battery and two monitors for about 10 to 12 minutes — but now it can hold a charger for 2 or 3 seconds.
The final straw came last week when my Brother HL-2040 laser printer (Keyliner reviewed- not recommended), printed a page and then surprised me by rebooting the workstation. When it crashed, a document was lost, the RAID array failed, and all kinds of other mayhem occurred. As I found out later, it had been crashing each time my children printed from their laptops — but they never noticed my computer Dell Studio 1537 battery had crashed. The prior week I noted the RAID was constantly rebuilding and when I put two-and-two together, I understood the issue. Bounces like this are hard on equipment and they were happening far too frequently.

Although it is safe to plug an inkjet printer into a UPS (on the surge-side), one should never plug a power-hungry laser into the UPS. But out of necessity, the printer and computers live on the same household circuit — this is nearly the same as being plugged in on the same power-strip. When the printer fires up, it pulls an amazing 450 watts and the lights throughout the house (and probably throughout the neighborhood), flicker. The power company rejoices.

Sadly, the UPS was compensating for this and I never knew. Each time the printer DELL Studio 1535 battery printed, the circuit had a mini brown-out and the UPS stepped in to save the day — that is, until it became too tired to work.

APC cs350:

I am partial to the APC brand cs350 UPS, which costs about $70 and you can get one at any office-supply store. It features a user-replaceable battery and surge protection for your phone/modem.

Installing a new UPS is a cinch: Plug it into the wall. Plug in the computer and monitor, and you are set. I don’t bother with the USB connector, which can tell the computer to shut down, but I probably should.

Most UPS’s, including this one, have two rows of plug-ins. One side is Dell Studio 1735 battery and surge-protected and the other is simply a surge-protected circuit (with no battery). Here is the back-side view of the cs 350:

User Replaceable

At first, I was going to buy a new, smaller UPS, figuring it was cheaper than a new battery. Replacement batteries can be bought directly from APC’s online store for $50, which is the same price as a new, smaller UPS.

But after a little searching, a replacement battery was found at a local retailer for $33.00 — these folks know their products and are pleasant to work with. If you mail-order, they include Dell Studio 1745 battery a free return-ship for your old battery (you must recycle these batteries).

To replace the battery, literally, turn the UPS on its back, and pull the battery out, unplugging a red and black cable. It takes about a minute.

The battery is surprisingly dense and weighs about 5 pounds but with this new battery, I expect to get another 4 years service. But long before then, when the laser printer runs out of toner,DELL STUDIO 1735 battery it will have a mysterious hardware failure, probably involving a baseball bat. This will force me to buy a new, less hungry printer.

Sony Thin And Light Commercial VAIO SA Notebook Review

31 Jan

Experience the simple appearance of thin

Sony laptop can close embrace many of the user’s eye, largely on the unique design allowed for more attention, particularly among white-collar ladies and business people of all ages, and high-end business notebook SA Series is not the color as buy, but more attention to detail in design, this new Sony VAIO SA notebook features a unique “side of hexagonal shell” design, inspired by the closed shell, the body lines more more use of the edge surface modeling, especially around the side edge of the body Sony VAIO SC battery treatment, which makes the body more vigorous and effective, all-aluminum exterior with brushed silver chrome material modification elements, highlights the whole simple and neat style.

Sony chocolate keyboard design very well, and its key words of comfort that has become more quick and easy entry, the Sony VAIO S also uses the smart switch button, two modes of switching can not only get high graphics performance, and When the operation switch to the core graphics mode, the host can also work more quiet and stable, for the safety of the machine, the Sony VAIO SA joined in the middle of the touchpad fingerprint reader, giving users a more secure protection more details related to the introduction of this Sony VAIO SD battery product please read the following article.

A fine and distinguished representatives of snow

Have to say this year’s notebook trend is moving towards the ultimate thin and light, especially in the field of business notebooks, the central processing unit (CPU) process technology is on the rise, the core graphics performance coupled with outstanding performance, the notebook can be designed more light and slim. Many manufacturers are now starting to focus on business class notebook research and development, have all launched their own thin and light notebooks, ultra-light business notebook could say that the future will be the best choice for high-end business users.

For consumer notebooks, 14 inch mold is the Sony VAIO SE battery best choice, and business people in the choice of more value when the notebook is portability, so the golden ratio should be 13.3 inches most appropriate, high-end business notebook Sony generally will not exceed this ratio, the Sony VAIO SA is no exception, using a 13.3-inch screen, matte display, the best resolution 1600×900 pixels reached, high score screen in the actual use of the images present a more delicate effect, while matte screen in strong light will not produce reflections, giving users a more comfortable viewing experience.

Fuselage frame just above the built-in support for a 1280 × 1024 pixels webcam, and built-in camera with the Sony software program at any time in the network video applications. In addition, the border around the screen layout of the bar is also a small pad to prevent scratching the screen wear.

Currently, most commercially available ultra-thin notebooks such as the blade is able to have the same body, the main reason is due to the very thin thickness control screen. Through our actual measurement, this Sony VAIO SA screen thickness less than 6mm, the thickness of the entire Sony VAIO VPCSA battery model is only 23.57mm, did not give up for a built-in optical drive notebook, the point where we could do that was very commendable.

In weight, this machine by machine plus the actual test battery weighs 1.623kg, coupled with adapter weighs 2.023kg, and did not give up because this notebook drive, so the weight is difficult to further breakthroughs , and such weight for users who frequently go out of office, is still quite light to carry, will not become a drag on the road.

Centralized arrangement of the interface layout

Sony VAIO SA interface layout at a glance, the fuselage on the left is the DVD burner – and 3.5mm headphone jack. The other interfaces are designed to focus on the right side of the fuselage, including Memory Stick Duo slot, respectively, SD memory card slot, D-Sub video output port external, HDMI high-definition video output interface, a USB3.0 high-speed data transmission interface, 2 USB2.0, RJ-45 Ethernet port and power adapter input.

On a personal habits, the Sony VAIO SA the right way to centralized Sony VAIO VPCSB battery interface arrangement is not particularly convenient, especially for frequent use of the right hand control an external mouse users, when faced with more USB devices connected when moving the mouse back and forth on the need to stay away from the right edge of the notebook, so the operation will give users some inconvenience.

Sony VAIO SA does not use a common shaft on both sides sink design, but rather arranged in the middle bottom of the screen, although the C-face for the whole layout to secure a larger space, but there are unreasonable, you can see this notebook is also designed to heat the air in the back of the central body position, when the laptop when opening and closing the screen angle is large, more or less block the ventilation efficiency.

Sony VAIO SA machine mold design does a lot of effort from the edge of the front fuselage processing point of view, you can obviously feel the left side of the body arranged in a common status indicators, including the wireless network card status indicator, charging indicator light and hard work, of which the bottom of wireless card light design also incorporates a physical switch, the user Sony VAIO VPCSC battery does not use the wireless network environment, at any time with just toggle switch off the wireless card, you can notebooks provide longer periods of time.

Sony VAIO SA back more structured framework, in addition to the cold air outlet and the docking connector, only one baffle, the baffle screws removed, the internal structure of a glance, as shown above were memory, hard drive, wireless card and battery bit, this Sony VAIO SA does not use a laptop directly to removable battery design, but the battery built into the body interior.

In addition, this Sony VAIO SA also joined the intelligent hard drive protection technology, faced a big jolt when the notebook is dropped or the case of shock, the smart chip will automatically detect the vibration of the current hard disk, hard disk read and write automatically head reduction, which play the role of hard disk data protection, enabling users to use more safe and secure.

Chocolate-style backlit keyboard

Still see the keyboard in the usual chocolate Sony design, can be said that in the history of the development of notebook keyboard, the adoption of chocolate manufacturers in the design program should be said that Sony is a relatively early. You can see, VAIO SA integrated all-silver notebook C-face style makes the overall feeling is very strong, the keyboard keys down slightly sunken area of the panel, and touch pad Sony VAIO VPCSD battery area to form a very natural too.

Upper left corner of the keyboard area arrangements drive eject button and STAMINA / SPEED laptop mode switch button, the second-generation Core processors with core graphics performance advantage, usually most of the applications can run in the STAMINA mode, the machine can maintaining low power consumption, in order to obtain more lasting use of time, and when the laptop needs accelerated graphics processing, can be a key switch to the SPEED mode, the notebook computing and processing capacity will quickly be raised.

Sony VAIO SA we used the keyboard is still the most favorite chocolate design, we can say Sony is the first keyboard using one of the manufacturers of chocolate, so this popular keyboard design is also currently the most respected mainstream notebook. Sony VAIO SA keys feel light and comfortable, the surface of the matte texture, the same time as Sony’s high-end notebook, the keyboard backlight Sony VAIO VPCSE battery below also joined by an intelligent light sensor to adjust, adapt to the environment based on the user’s keyboard backlight Shading can also be followed automatically adjusted.

The keyboard is a laptop touch pad just below the area of the touchpad as a surface decoration using Check, so keys are more bright metallic luster chrome plated, touch the button press area is relatively well-off, even if the user uses a finger thick also no problem, the key process is relatively short, the user will feel a bit stiff to operate.

Furthermore, in order to improve laptop security, the center of the touchpad buttons where placed a fingerprint reader, users can fingerprint recognition software to encrypt files and system settings, effectively prevent the theft of commercial information, which is For business users is essential.

Review summary of articles and business experience

The new Sony VAIO SA battery provides users with a total silver / black two colors, silver and our evaluation of this section is more suitable for ladies to use, the whole fresh slim design highlights the business people able temperament . The use of a 13.3-inch 16:9 matte screen, the best sub-rate 1600 × 900, less than 6mm in thickness of the screen moving up and very light, while the whole body with metal, weight control 1.623kg , into a briefcase, like a magazine than to carry it, is traveling business people the ideal choice.
Sony VAIO SA built-in 4400mAh 49Wh lithium ion battery, battery life up to 3 hours, 46 minutes, the notebook also supports a second battery to cope with longer duration of use, In addition, the machine uses a high-capacity 750GB hard drive, and capacity than the previous generation has been very significantly improved, while also adding a hard drive protection technology, allowing business users in the course of more assured, in addition, random notebook also installed Windows 7 operating system and Office Professional 2010 office software.

Weight, heat dissipation and battery life tests

Thermal aspects of the software we used FurMark to make this machine run at high load condition, after an hour or so of time, CPU temperature rose to 90 ℃, the core temperature has reached 90 ℃, GPU temperature is 90 ℃, from the kernel temperatures reflects the Sony VAIO SA’s internal cooling efficiency is not high, however, for such a high all-around with discrete graphics with a thin and light notebook Sony VAIO SB battery, because the body itself, the design space and heating element causes a higher concentration, can do This still can be justified.

By convention, through the thermal imaging devices we face C and D body surface temperature of the test surface. Among them, the most contact with the user’s keyboard part of the maximum temperature of 42.2 ℃, the maximum temperature of the bottom of the fuselage 54.6 ℃. From the heat distribution, we can see, the highest temperature of the red zone, the surface for keyboard, the keyboard focus on the right side of the red zone, while the heat is concentrated in the bottom of the window part. Actual use, the overall feel of the keyboard zone temperature control is also good, but the fuselage bottom heat is not particularly desirable, if used on the lap of the phenomenon will obviously feel the heat.

After we have the notebook’s battery life was estimated test, the Sony VAIO SA built a 4400mAh 49Wh lithium ion battery plates, we first adjust the Windows 7 operating system power management for energy-saving state, adjust the screen brightness to 50 %, while on the wireless network card, 100% of battery capacity in SPEED mode, you can support 3 hours 46 minutes, primarily as a commercial product, endurance performance is not particularly outstanding, but if you want to deal with long-distance travel, users can also matching the second long-lasting laptop battery life to increase their use of time.

Review summary: the ultimate portable light performance

Sony Laptop design has always been the biggest selling point, the representative of the high-end business notebook Sony VAIO SA Series battery also confirmed this point, less than 24mm thin body gives extremely impressed, and in the hardware configuration, the first second-generation Core i7 processor and AMD Radeon HD 6630M can respond to business people working in a variety of requirements, the whole performance in thermal control is not ideal, this is the soft underbelly of most thin and light notebook. Sony VPCSA27GC this website is currently priced at 13,999 yuan, not suitable for general consumer use, and for high-end business people who are still worthy of consideration.

Practical low-cost business evaluation of the Dell Vostro 1440

30 Jan

New laptop on the market after another, to purchase laptops for the first time a friend who may not know where to start, business notebook product category can be divided into the relatively small: this game entertainment, entertainment book, entertainment book, notebook economy , business notebook, and so on. Business notebook is one of the most widely used audience of a class of models, and therefore extra attention and favorable.

Today, we bring the Dell Vostro 1440 business notebook DELL VOSTRO 1420 battery series (hereinafter referred to as: V1440), V1440 use Intel Core i3-370M processor and the AMD Radeon 6450M graphics card configuration program, 14-inch 1366 × 768 resolution, 16: 19 LED backlit screen, 2G memory and 320G hard drive. Next we look at its specific performance.

Dell V1440: Transverse groove design case

Dell and the Dell Vostro V1440 series of products from the appearance before making some changes. A gray surface to maintain the stable characteristics of the business, the middle letter of Dell Logo simple and generous. Although the A-side plastic, but the horizontal lines through specially designed for elegance, Sese non-slip surface has become more prominent, of course, the fingerprint will not be left in such a case the above.

Dell V1440 screen 16:9 ratio 14-inch LED backlit display, the best resolution of 1366 × 768, the top left of the screen is VOSTRO identity, the middle is the front-130W pixel camera, which is now standard notebook with one camera next to a pickup holes. In addition, there are two sides of the DELL Vostro 1500 battery screen is on the cushion, the screen under the pressure of the border to avoid direct contact with the palm rest, play a buffer role.

Dell V1440: brushed metal palm rest, spill-resistant keyboard design

The gap between the right chocolate keyboard, click on a collision while another is not easy, is conducive to fast input. Trial process, the keyboard can understand the appropriate keyboard key way, overall, the keyboard feels very good chocolate. In addition, the keyboard is also spill-resistant keyboard, can effectively prevent the liquid against the body.
Touchpad is very large compared to some of both sides of the palm rest a little sink, brushed metal feel the touch area is good, more accurate positioning, left and right DELL VOSTRO 1420 battery buttons area is also large, medium strength to complete the operation, but sometimes will be left with at the scene.

Dell V1440 machine weighs 2.185kg, travel weight of 2.505kg, from comparison with the $ 1 coin thickness we can imagine the weight of the V1440′s not too light, but the whole weight of 2.185kg this in not in the 14-inch be heavy, a general level.

Dell V1440: Interface types are more complete

Front of the aircraft structure is as follows, left for the four status lights, the middle was one card reader, and reader design default protection shell. Reader’s position relatively close to the user, easy to use. Both sides of the design of the back-end DELL Vostro 1450 battery security keyhole, and power jack. Interface is designed to take full advantage of the rear fuselage space performance. But the back-end mold design is not very beautiful, in the middle relative to the right and left protruding a lot.

The most common interface is arranged on the sides. The left side of the interface followed by cooling holes, RJ-45, VGA, HDMI and USB 2.0, close to the user can use the USB interface external devices such as U-disk, VGA external users to meet the needs of slide projector, and HDMI interface allows users to enjoy their leisure time external HD service. The right side followed by a headphone jack, microphone, DVD burner and two USB 2.0 ports, slightly rearward of the two USB ports can be used for external wireless mouse receiver or a wired mouse connected. Interface layout is very reasonable.

Dell V1440: heat, endurance test

In considering the performance of today’s notebook users at the same time, heat, life has gradually become the focus of attention, which is a good judge of a laptop key. Dell V1440 heat very well in PCMark Vantage runs a half hour later, V1440 keyboard area is only 34 degrees maximum temperature, minimum temperature and room temperature is almost similar, look at the back of the body temperature, maximum temperature in the fan area, reaching 38 degrees, but in general, DELL VOSTRO 1400 battery heat very well, for business people it is very important.

The level of natural life is derived under the ordinary application of the test results, the results are very satisfactory, MobileMark2007 gives 216 minutes of battery life duration, equivalent to nearly three and a half hour-hour count for the user unplugged use.

Dell V1440: hardware, performance testing

V1440 equipped with Core i3-370M processor, plus AMD Radeon 6450M graphics card, the machine’s hardware configuration is balanced. In addition, standard 2GB DDR3 1333MHz and 320GB hard drive can also be well positioned to meet the user’s storage needs.

If the Cinebench R10 test is easier compared to the standard form, then join the Cinebench R11 is a gradual transition PConline evaluation room, the better version of the DELL Vostro V1720 battery test program the system to drain the last bit of performance and fps units with more pts intuitive and more ordinary users can understand (fps frame unit, pts point unit).

AMD Radeon HD 6450M is a low-end single display, through the 3Dmark06 score you can see that. But for a business notebook case, 3D demand is not the most important, so AMD Radeon HD 6450M graphics card is enough.

SYSmark 2007 Preview is a software platform for a variety of PC performance testing software integrated, can be used to install most of our daily fidelity simulation software to run applications (word processing pictures, video playback, 3D performance, etc.), so the test results for the office and entertainment applications are very true and accurate, has been recognized by the industry. DELL Vostro 1440 batteryaverage score 128, scores in general.

PCMark Vantage can measure all types of PC’s overall performance. From multimedia home entertainment system to the notebook, from professional workstations to high-end gaming platform, whether in the hands of professionals, or belonging to the ordinary user, can understand the system performance through the PCMark Vantage test content can be divided into the processor test, memory test, graphics test, hard disk test.

Summary

Relative to the performance-oriented consumer laptops, office business class notebook is more focused on the good work, excellent operating experience, as well as secure data protection and other aspects of performance in these areas on the performance of the Dell Vostro 1440 are good, then with perfect cooling performance, it can be said V1440 is a qualified business notebook is a good choice for business people.

HP Desktop PCs P6235CN Reviews

17 Jan

HD, as a high-resolution digital video technology, Kusakabe has become a popular high-speed multimedia specifications, we said earlier 480i or 480P format has been completely out the user’s perspective, instead it is the overall promotion of 720P and 1080P. From the computer user’s perspective, you want to watch full HD video, in addition to high-definition image processing we need to speed up the equipment, such as multi-threaded processor, hardware-accelerated graphics card, but can support full HD display is also indispensable.

As technology continues to improve science and technology, support for full HD equipment in the manufacturing cost of the hardware has been significantly lower than in the past, so the sales price has also been very approachable, and many need to purchase computer users have begun to focus on high-definition playback up. The current market view from the computer, notebook computer in cost control and competitive price under the premise of the two all the way down, many brands of desktops than laptops getting smaller and smaller Compaq Presario 703 battery the difference, plus manufacturers spared no expense in terms of publicity , a wide range of advertising overwhelming, making the notebook computer market to replace all of the great potential. But there must be something of the truth of its existence. Conditions from the laptop’s hardware point of view, high definition decode acceleration does not seem a problem, but the key in the display output, due to size restrictions but has inherent deficiencies.

In fact, the advantage of portable notebook itself, the real price competition with the desktop, practical or even the existence of performance did not comparable, so the main high-definition video, video games and the desktop is still irreplaceable, which is present in many computer manufacturers in the consumer desktop product design on the tendency of the main aspects.

P6235CN appearance resolution display articles

China concerned about our driver friends the whole channel of our evaluation process should be very understanding, yes, we are still the appearance of the whole computer from the start, but the display is the first appearance of the evaluation component.

Speaking P6235CN display can not say that this is HP’s pride, P6235CN with HP’s new 23-inch high-bright mirror-screen display HP2309p, display parameters from the point of view, the monitor configuration and performance is very high, although the panel used not high-end IPS hard screen, but the mirror coating allows HP2309p display no less than its IPS panel products. We all know that, with CrystalBrite screen technology on display in the display brightness is outstanding, and this HP2309p not only hardware using high-lumen LCD panel, the core technology is integrated into HP’s HP BrightView ultra-bright screen technology, in The default display brightness and contrast case, the details of images and video performance is in place, color sharp, lifelike images. 1920X1080 16:9 widescreen high-definition display parameters for HP2309p display capability. Rapid 3ms response time in the same size of the display is outstanding, which makes HP2309p not only high-definition video performance Compaq Presario 1525 battery is perfect, the game also can be expressed hearty. In addition, HP2309p in the display interfaces include not only our common VGA and DVI, and HDMI output interface, and there is no less, and since HP2309p equipped with a dual-channel built-in speaker, so the 3.5mm audio input interface is necessary. We can use the time to host their own NVIDIA G210 graphics card as a sound card, the monitor comes with an HDMI cable to simultaneously complete high-definition video and high fidelity audio signals are fed.

Complete understanding of HP2309p main configuration and parameters, let us look at the appearance of the details. HP2309p body shell with a piano paint the whole production process, and use the silver screen frame, looks more stylish. Rear panel with streamlined design, although looks a bit thick, but the effect on the heat has to be greatly superior to ultra-thin models. HP2309P the base with rounded corners deal, all the silver paint looks very avant-garde technology, in addition, one-piece foldable cradle to put away extra careful when trying to display, which avoids the common base of demolition to save the trouble and split Compaq Presario 1714 battery the trouble. Also designed the back of the base closing clip device. Compared to other liquid crystal display, 2309p set even more of closed clamp integrated with the fuselage. Monitor conditioning and low-end models is different, HP2309p not only highly variable, but also can flip, this unique configuration of the display in general we can only be seen on high-end products.

The menu display area, HP2309p abandon the previous push-button operation, instead it is completely touch-switch, we can simply finger close to the operation, which seamlessly compatible with the display not only makes the display control button the overall look is more upscale, convenience in manipulation also significantly better than the push-button switch, which especially in the monitor speaker volume control aspects.

Finally, the display control menu in HP2309P can be used to describe fully such HP2309p provide regular sleep function that allows the display automatically after a certain time, low-power sleep state, and can automatically set the time allowed to open. Along the lines we can use the following menu case diagram to understand.

P6235CN appearance analytical articles Companions

Complete understanding of the display, we then look at another peripheral, that is, the keyboard and mouse. Very much regret that the P6235CN still in the mouse and keyboard configuration using the USB cable to connect the traditional keyboard and mouse, and they use the current configuration of the model in terms of an infinite, P6235CN of the configuration obviously take a little less tune. But compared to the business model in terms of, P6235CN the mouse and keyboard set can be considered very fashionable, from the appearance of mold on the point of view, P6235CN mouse and keyboard and HP wireless mouse and keyboard set looks basically exactly the same, the only difference is that P6235CN drag the mouse and keyboard HP Pavilion ZE4350 battery a long tail. We can picture to look at this mouse and keyboard design.

Mouse, the large design for men, the grip is very comfortable, but small hand-type female users may need some time to adapt. As the mouse without increasing weight, so use very lightweight, web browsing for users who frequently very useful.

Keyboard, the overall tone with black, with a silver outer edge, this design and monitor cross-echoes, the palm rest and the key position of ABS matte material, other locations may be reflective mirror coating to retain the effect, strong business atmosphere. The thickness of the keyboard keys in all-thin design, very comfortable to use, and mute the effect is obvious. We can see the keyboard’s left side also retained the Ctrl key combination Fn multi-function, this is because the use of ultra-narrow design of the keyboard, multimedia keys Play button was placed in the F5-F8 keys on, so it is necessary to use with Fn . Top right corner of the keyboard left alone out of the sound control keys, the keyboard is no different from ordinary keypad, but the text area control keys, Delete to delete keys are deliberately designed to become a major key, so delete operation is convenient, but the possibility of misuse also increased. We will turn over the keyboard, you can see the keyboard on the back of Hp Mini 210 battery the drainage holes, can be seen this keyboard is also used waterproof design, the liquid outflow holes can spread quickly so do not accidentally spill water on the keyboard or drink fast outflow, water play the role. In addition, we found no P6235CN configuration with a remote control, chassis parts and no infrared sensor and TV card and other related equipment, which is due for the positioning of the models.

P6235CN appearance to resolve the host chapter

Next we look at P6235CN vital components – the host. From the appearance of speaking, P6235CN host looks more like a business model, but with our common ATX standard case the difference is, P6235CN total with two 5.25-inch drives and two 3.5-inch hard disk location location So this whole host of significant size to be smaller than the conventional case, although S5235CN are bigger compared to the point, but in the HP Mini 311 battery heat and scalability to be more suitable for recreational users, such as we are not satisfied with the performance of graphics circumstances, or not enough disk space required to add a large capacity hard disk, these by extending the P6235CN good host can easily be achieved.

We first look at the host’s front panel. In the case of the top we can see the power button is placed in the position of the most easy to press, which often hosts on the table next to the user who is very convenient, eliminating the trouble of bending squat. S series between the host and the difference is P6235CN vertical design with a whole, so is the use of transverse optical drive, so that the width also increased, but to use than the vertical set of easy to use multi-drive tray. Position in the optical drive on the desktop PC is one of many very rare configuration, 15-in-1 card reader, the reader is compatible with a variety of interfaces currently available memory cards, the card reader than S5235CN to the more comprehensive. For example, users are more often used photography to the CF card, and P6235CN can not drop a perfect compatibility. In the reader’s right, we can see P6235CN host work lights, in addition to power, there are hard working lights, the configuration of this essential in our daily use is very practical. Here is the drive location for HP’s specially reserved for removable storage devices dedicated access slot, HP will be named HP Pocket Media Driver Bay, it can be achieved through removable storage devices with the HP hot-plug connector. Perhaps you will see here a little puzzled, because you will probably find that just does what’s right and that is our common HP Pavilion DM1 battery front USB ports and audio input and output. In fact P6235CN mystery here, we will be with the HP logo panel gently push down, we can see them, and do affect the interface that can prevent the dust exposure level, but also beautiful front panel, can be described very unique design.

Then we then pass behind the chassis, to see which interfaces are P6235CN in the end. Since the hardware configuration from the point of view, P6235CN with a separate graphics card, so even P6235CN uses a G41 motherboard, the government has also not recommended, but the onboard VGA port sealed. In addition P6235CN equipped with a USB keyboard, so common before we will all PS2 keyboard and mouse interface, eliminate, and indeed the current USB mouse and keyboard compatibility point of view, bandwidth is small, poor and can not be achieved for the PS2 mouse and keyboard hot has no longer necessary, the current retail on the DIY market board also illustrate this point, but before the serial and parallel printer interface, and so long annihilation. Other common interface also includes four USB2.0 ports, Gigabit Ethernet and 5.1 channel audio input and output. The interface also includes a discrete graphics display device is currently the most commonly used of the three interfaces: VGA / DVI / HDMI.

In P6235CN host heat, we can see very good duct design, in addition to the HP pavilion dv2-1000 battery chassis side panel on both sides covered with cooling holes, the front panel, also designed the inlet channel, while the back of the chassis there is a low-speed static Music fans, spacious interior with the chassis design, P6235CN even in the case of full load can also be very cool work, but also because the natural heat of the ideal to provide favorable conditions for the mute. P6235CN boot into the system in addition to tens of seconds before the fan running at full speed, other times are running at low speed, which makes the machine very low ambient noise in the place of work can not feel P6235CN noise.

Summary

So far we have completed the overall HP Pavilion zt3000 battery evaluation of P6235CN, I think we have it their own views of a bar. Indeed, P6235CN As we might expect, although the performance of performance in the game and not wishful, but like high-definition video entertainment users, P6235CN is undoubtedly the best choice, which is when the HP in the development of P6235CN mind, the other P6235CN spacious box, like the hands of the user touches a reserved space. In the final analysis, we do not want the above Detailed advantage of P6235CN then go into a lengthy, just HP2309P magnificent display that I think many users will be tempted to it, and finally we can only say that in addition to mouse and keyboard a little behind, the other are no critical problems.

Metal Storm struck Dell Vostro 3400 Review

12 Jan

Notebook to the present, divided into commercial and consumer has become increasingly blurred, the business models of many brands have begun to add more fashion elements. Dell recently released a new Vostro 3000 series products, Vostro series of Chinese name is “success” from its name in the business we can smell a trace of taste. And compared to the previous appearance, the Vostro 3000 to enhance the performance of a listing on the concern by many consumers.

The release of the new Dell Vostro 3000 series notebooks include the Vostro 3300 13-inch and 14-inch Vostro 3400, and we received this product as a 14-inch models. The new range of DELL Vostro 3400N battery products and compared to the previous generation, the biggest difference is that they have a more lightweight body, and also with a metal roof material, mold upgrade also “Vostro” this classic, traditional brand glow a new luster.

In addition to the appearance upgrade, the Dell Vostro 3400 is in the configuration of a comprehensive update. The use of the Intel family of processors i, with HM57 motherboard and hard drive is elevated to 7200. Also learned from Dell’s website, its configuration i3 processor + alone significantly model priced at just 4599 yuan, price is very prominent.

Overall Appearance

Past two years, became popular notebook “Metal Wind”, just before the spread began in the high-end notebook of ordinary metals, the current 5000 yuan notebook has already begun in some areas the use of a metal material. The evaluation of this Dell Vostro 3400 with a metal roof, so you can make the body more resistant cap, hard, and the screen can be done more light. In addition, this machine’s top cover DELL Vostro 3500 battery does not follow suit like brushed metal effect, but the satin finish, do not have a taste.

Compared to performance, business people tend to pay more attention to quality, but as a business notebook, the most important details of the deal also must be in place. We see that this machine has a front screen recess design, so users will be more convenient to open the screen, easily. Another even more important is that this machine can be used directly on the screen with one hand, the process of opening the base of the phenomenon is not upturned, and the screen turned on fixed well, this is not all laptops are able to do.

The machine configuration is a 14-inch matte screen, the standard resolution of 1366 x 768. Here should be mentioned that, Dell Vostro 3400 still stick with the matte screen is commendable. We understand that many other brands of business notebooks with a glossy screen, calling the fashion, in fact, we know that the phenomenon of mirror-reflective screen is very serious, is not suitable for viewing, matte screen is more practical compared to some, Dell hopes to put this tradition continue. However, this machine and other DELL Vostro 3700 battery products using a 16:9 screen ratio, which is still slightly make people feel some regret.

This machine is equipped with top of the screen of a camera, the left is the status indicator, and then the outer sides of the hole is the microphone array, which describes the configuration is no longer too much, almost every laptop notebooks are now this is the design.

Keyboard and touchpad

In the keyboard layout, designed this machine is quite acceptable, there is not much special about it. The only noteworthy is that a lot of Dell products and Fn keys F1-F12 function is the opposite of cooperation, also said that if the user wants to press F1, it must be achieved with Fn. However, the Dell Vostro 3400 is different, it and the traditional notebook, as identified on the special function keys with the Fn function needs to use.

Whether Stuido, Inspiron or Vostro, these products now in development to have a common characteristic, which is almost the same keycap design, a little depression on the surface, with contours and layering effect of fine grinding process, it seems Dell is very proud of this design, all of it will be a wide range of applications.

In addition to media control buttons DELL Vostro 3700N battery in addition, this machine’s control panel are the power switch and status indicator. Basically, most notebook displays were placed in the state together, including wireless, Bluetooth, hard drive, Caps Lock, etc.

Interface and body weight

In the interface design, this machine equipped with the right side of the fuselage USB interface, cable interfaces, card reader interface and Express Card. And because this machine uses a 14-inch mold, so it is equipped with a DVD burner. In addition, the card reader and Express Card interface, very close by, want to insert some special dimensions of the device does not conflict.

We see the left side of the fuselage is relatively more interfaces, including USB ports, HDMI port, VGA port and power connector. The right side of the fuselage with a USB interface, this machine is equipped with a total of four USB ports, so the number for the average notebook is already very much. Also DELL Vostro 3500N battery to mention is that the fuselage on both sides of the interface of the red cover is metal.

In addition to the right and left, the Dell Vostro 3400 front side of the fuselage also placed a pair of audio interfaces, and both sides also has a wireless network switch and power indicator light.

Easy dismantling and weighing

Although we found the battery compartment in the body of the 3G slot, but we do not have the Device Manager, find the appropriate module. If you need to have 3G, you may need special custom, after all, currently DELL Vostro 3400 battery there are three standards for 3G networks and terminal equipment is currently not interoperable, so any standard notebook manufacturers also ventured a standard 3G module.

This machine with its own card for the Dell Wireless 1520 MiniCard, Wireless LAN currently has a long version and short version, but this machine is used for the short version of the smaller body type.

Business users should pay more attention to taking into account the protection of data, so this machine wrapped in hard drive, a metal frame, so the hard drive can be better protected. In addition, this machine is equipped with a 2GB memory, we see that there is a remaining slots available for users to upgrade future use.

In weight, this machine machine + battery weighs about 2.1kg, with the adapter weighs about 2.6kg for a 14-inch notebooks, 2kg weight can be said that his early maintained very good the.

Cooling and endurance tests

In the temperature test session, we used a thermal DELL Vostro 3400N battery imaging device on this machine for temperature testing. First we make the machine at 26 ℃ ambient temperature around full load operation, you can see the processor temperature has reached 79 ℃, and the motherboard chip temperature has reached 84 ℃.

The results from the test point of view, the maximum surface temperature of the keyboard 44 ℃, the maximum temperature of the bottom of the fuselage 47 ℃. Although this figure seems high, but from the heat distribution, we can see, with palm rest and keyboard users access to the parts of the temperature control is OK, so in actual use will not feel too hot.
The machine configuration is 56Wh lithium ion battery. Adjustment in the system as a “power saving mode” in the case, this machine’s battery life is 2 hours 52 minutes, for business products, such as battery life is not good, can only say that the basic qualified.

Summary

Just from the cost point of view, Dell Vostro 3400 does not account for much advantage, after all, the current i3 + notebook discrete graphics have been pressure to less than 4,000 yuan. However, this machine is the concern by many consumers, in this regard on the Dell brand value as where the other is the DELL Vostro 3500 battery is indeed good workmanship and design, more lightweight body plus metal The cover of this machine is recognized by the many friends the main reason.

The 3G CDMA Version Of IPhone 4 Internet Review

09 Jan

CDMA version of iPhone4 year has officially listed in the U.S., consumers can be the exclusive operator Verizon and Apple stores to buy the operating room. According to related statistics, CDMA version of iPhone 4 listed on the first day of sales exceeded 500,000, a record first day sales of Verizon’s new product the most. And quite a few phones like Apple’s friends have been concerned Apple 13 inch MacBook Air battery about the CDMA version of iPhone 4 in a variety of messages.

China Telecom’s CDMA standard, as domestic carriers, the technology has also been improved debugging on, before the C network in Fuzhou iPhone 4 would be able to voice calls, 3G Internet access is also now to be able to achieve, last we took to successfully burn a number of the CDMA version of iPhone 4 for trial on the CDMA version of 3G network speed, MMS, FaceTime, costs and other Apple iBook G4 12″ battery issues, we will in the following evaluation for you – to answer.

iPhone 4 CDMA functionality in the hardware configuration and application versions with the iphone 4GSM no difference, but the difference between the network only. CDMA version of iPhone 4 iPhone front of the box printing new frame design, while the box is also printed on the bottom of the U.S. operator Verizon logo. And accessories in the existing AT & T version of the same charger equipped with a green dot.

CDMA version of the Apple iPhone 4 uses Apple’s latest iOS 4 intelligent operating system, compared to the previous version of Apple iPhone 4 increase in WCDMA mobile AP function, so that users can at any time for mobile devices around the network to provide wireless hotspots, so the Apple M9422 battery mobile office more handy.

3G to WiFi signals to communicate, and also supports up to including the iPad, including five WiFi devices, expanding and more powerful.

No. not burn before, this iPhone 4 only the equivalent of a high-priced Apple iPod touch. No. But after burning, this iPhone 4 can be regarded as a genuine phone, because he can call. Machine “burn in” a number 180 at the beginning of China Telecom, and other cell phones can be a normal call.

Number of burning

Foreign CDMA network operators to customize the models are used without SIM (or UIM) card design, the information they need to write the phone number to let the network work properly. This information included the number of mobile phone operator is called “burn number.” Example of this we have reviewed the CDMA version of iPhone 4, users in the United States in the form of purchase contract Apple MacBook 13″ MA254LL/A battery machine, operator Verizon will be able to write the phone number information, to make it work properly. The current burning issue of two ways:

Five yards burning No.: refers to the ESN (electronic serial number), International Mobile Subscriber Identity (IMSI), A-key, AA code, AN code written to the corresponding mobile phone, so that it can be used normally. However, most areas not currently open to the general user query five yards telecommunications services, only through informal channels high (several hundred) to check their cell phone number five yards, and then by a professional staff to write data to the phone.

OTA burn number; refers to mobile communications (GSM or CDMA) air interface of the SIM card data and applications for remote management technology. It simply is the operator Apple MA561 battery via the wireless network information into the mobile phone number, users can simply complete the operation. Of course, this requires operators to use in opening up the job, but has yet to open the service of China Telecom.

At present, we can not determine the evaluation of the CDMA version of iPhone 4 in the end is the use of which means burning number. However, estimates that if the CDMA version of iPhone 4 in the country have great market demand, China Telecom does not exclude the formal introduction of the iPhone before the open burning No. OTA service.

Telecom China Unicom iPhone comparison iPhone 3G connection speed measured

This iPhone 4 in the burn Hao after successfully supporting China Telecom’s CDMA 3G network, whether it is an ordinary web browser or download speeds are so Bizhexiangdang satisfaction, see the following detailed description.

After burning the iPhone number displayed on the taskbar at the top of the “China Telecom” 3G signal. Displayed on the operator system Apple M8983 battery compared to the previous version has been able to correctly identify the name of the domestic telecommunications, system version is 4.2.8, I understand that the system upgrade is to be set for the dealer to be Nadao upgrade, upgrade the user’s own need to re-burn No..

3G Apple iPhone 4 Internet as one of the important functions, whether normal use, but also many of my friends about things, we compared the same time open FJ007 Unicom WCDMA Youku website online and compare who is more to the power of 3G, compare to see it know.

Can see from the video, the speed of the two to meet the needs of their 3G, iPhone itself sharing with hot, I open the share, the laptop hotspot, Thunder official website QQ2011 test version download Tencent, China Unicom version of the stability of the performance of people quite satisfactory. Telecom CDMA version of the fastest to 150KB, the slowest to 20KB. Inferior Unicom Telecom speed, but stability is also acceptable.

MMS and Facetime function, I tested this current telecommunications iPhone 4 or can not receive and activate, small series from the dealers Apple M8433 battery understand that the iPhone 4 C network will be the next version of the MMS solution BUG. I would think that fewer people now use MMS, 3G smart phone transfer pictures directly to talk through the meter, micro-channel can also be replaced. Facetime currently open can not be successfully activated, and this CDMA version is displayed as “awaiting activation.”

FaceTime active principle from the point of view, mobile phone through wireless WiFi network operator to send the activation request, the server gives operator feedback, the phone receives a feedback after activation. It may cause the reason it can not activate FaceTime may not send a request to the operator or the operator receives no live feedback, which is a specific reason, we are unable to determine.

Summary: From the user point of view, CDMA version of iPhone 4 burning issue of the success will provide an alternative, especially the original telecommunications users, if you want to use the iPhone 4 will not have to move Apple MB771 battery or China Unicom’s network, eliminating the need a lot of trouble. Lower prices, more choice, consumers will be the biggest winner.

Core i3 Lenovo ThinkPad L412 Notebook Review

06 Jan

The classic appearance of the product there is always a classic, big-name products always leave traces of their own style, you just look at the lights as we know it belongs to the Mercedes-Benz, just to see Little Red Riding Hood knew that the source Since the ThinkPad. Of course, the era of progress, the consumer point of view, too, are changing, classic faded original front side to show their coat Lenovo 40Y8315 battery is easy to understand. However, we also lack many of them around the plot of consumers with nostalgia, so it makes a kind of iconic classic is often difficult to let go.

Beginning of the year in 2010, Lenovo announced the ThinkPad unprecedented sub-brand Edge, red, white and other bright colors begin blooming in the ThinkPad family, so this marks the ThinkPad will not be based on a traditional black-face show business people.

The association also expressed that the brand extension is the classic while retaining the original brand image, while the use of sub-brands close to a modern aesthetic rejuvenation.
Lenovo’s new ThinkPad notebook a business – L412, classical and avant-garde Edge and SL series is different than the latest L-series notebooks are a new user on behalf of SME propensity to consume. Although it follows the classic ThinkPad look and feel styles, but it is equipped with the latest Lenovo 41U5027 battery Intel Core i series processors, the use of three generations of mainstream DDR memory, while a 16:9 high-definition LED display, the interface also tend to round, Therefore, for small and medium enterprises in the field of commercial office, L Series ThinkPad notebook is undoubtedly a young and dynamic generation.

Appearance and specifications of analytical measurement

Not in appearance obviously need a little extra ink for the ThinkPad’s classic look, we like us too familiar. See L412 overall appearance is very simple, in addition to the lower right corner of a low-key style without losing the ThinkPad logo, the other has no flashy place and worth detailing. And more neutral than the SL series notebooks, L412 and not with a stylish piano paint finish, instead of using the traditional matte-type material. Although it looks old-fashioned of frosted plastic no advantage, but in the anti-pollution and anti-wear, the piano paint materials is absolutely not the traditional rivals. This material, Lenovo is the official statement, that is, L412 is used in the green plastic body, and its use for about 30% of recycled materials for manufacturing. Duiyu deterioration of the Earth environment, out of very fast electronic products is a huge killer, while other harmful substances Lenovo ASM 92P1187 battery in the composition of the atmosphere and water, the same will jeopardize our human health. IT industry association as a giant, and its protection of the environment to human survival as the production of guidelines is clearly worthy of study. In addition, the strength of the material is very reliable, the impact resistance on the deformation of the buffer has a good performance, strength and toughness are also very good, will not be easily crushed. All in all, ThinkPad’s material is worth reassuring.

In body shape, L412 and have not used the latest Intel Core i-series platform to be thin, but compared it touches a lot of calm, which is also due to the use of a full thickness of the DVD drive some impact. We use electronic calipers and electronic platform scale, respectively, the thickness and weight of the machine were measured, of which the thickness distribution as L412 is not exactly the same, so we use were measured way. And for the weight, we measured the whole state and then travel status two data results.

Man-machine interface

Man-machine interfaces, L412 can be described as extremely classic, this is the classic blend of many elements of the place lies. Overall, L412 of the whole body black business Lenovo ASM 42T5217 battery style has not changed, but the details of the performance we can see many changes and improvement.

Display, the overall size of the new 14-inch display but relatively rare. L412 is more popular nowadays with the standard 16:9 ratio widescreen vision, while LED backlight technology for the whole of life and the life of the display offers many advantages, also in the display, L412 using 1366X768 resolution high-definition display is very good. In the absence of mirror screen, so viewing angle is very large, and effectively put an end to bring in the outdoor use of reflective glare problems.

Just above the display is a 130 pixel camera, the Internet has been fully integrated into the era of people’s lives, notebook camera also has become a standard, this is particularly important for business, video conferencing will directly increase frequency of use of the camera in the imaging area, L412 camera performed well and respond very quickly, there is no obvious smear phenomenon.

L412 has become a classic of the shaft to retain elements, although the batteries have been placed in the L412′s rear side, but did not use the sink shaft design, so you can be part of the wind Lenovo FRU 42T4514 battery crossing the interface placed in the back of the laptop to take advantage of computer interface space.

Just below the screen is the audio part of the L412, L412 with a two-channel stereo, placed in the bottom of the screen design approach clearly has not see in other brands, but in fact this is nothing but the alignment in order to save more to reduce costs, improve production efficiency. While the user is concerned, no significant difference between the use of feelings, but the channel perpendicular to the desktop the way to work, the effect is still the best.

Control area

Regional aspects of control, L412 and earlier still has a clear distinction between products, including the power button, multimedia shortcut keys, working status indicator for the change of placement is clearly, along with before on the keyboard in different ways, these buttons and light in the L412 are located on both sides of the keyboard. Among them, the system maintenance ThinkVantage button is marked with a special blue button in the surrounding environment of a large black looks very conspicuous.

L412 keyboard part is nothing special, the same full-size keyboard, very appropriate keycap size, button keys shorter duration, intensity is also weak, so very easy to use. In addition, the durability of treatment also makes the keyboard keys do not wear the pan with light, the overall feeling of quality Lenovo FRU 92P1188 battery compared to the ThinkPad keyboard is still better than many other brands.

Little Red Riding Hood followed with the same touch pad area the same design with a classic two-button, wheel button is retained, the strength of keys is also very soft, no annoying sound Kaka. But little change is touching the material using a non-smooth touch surface, but with vertical and horizontal lines of the design, feel significantly improved.

Interface section

L412 can use the interface part of the all-around to describe the number and placement of the interface are very much in place, which for a business laptop is undoubtedly improve the compatibility of a variety of environments, such as video interface compatible with multi-range will enable us to report in the conference room for more video output devices can be linked to demonstration. Compared with the ultra-thin notebook, the L412 thick body design is very conducive to placement of the interface, so this has become a comprehensive interface, Lenovo ThinkPad L421 battery favorable factors. We take a look at what are the interfaces L412.

The left part of the body from top to bottom are: cooling wind crossing, VGA video output interfaces, e-SATA port, RJ45 Fast Ethernet interface and Display Port interface.
The right part of the body from top to bottom are: security keyhole, power adapter input interface, DVD drive position, two USB2.0 interface, multi-card reader slots and wireless network switch.

L412 front side of the body and did not place the interface, but the power and the battery indicator was placed in front of the fuselage, and the depression of the way through to design a very reasonable opening and closing screens cover the absence.
The interface is very small rear fuselage, the main space occupied by the battery, which left also has a cooling duct design, and different from the previously mentioned left duct is the duct is possible that the road into the air damper , the other is the outlet. The other side in the rear is a separate power supply with USB port, the USB interface can be shut down in case the system still provides a +5 V power Lenovo ThinkPad L512 battery supply, user interface devices for USB charging.
We will flip the fuselage, and then look back, what a unique place. Most of which have business in this bracket have the same interface on the L412, the user can choose according to demand, in order to expand and use for the notebook to bring other more convenient.

In addition, we also found the back of the liquid interface to identify the discharge hole, because the L412 with a good a waterproof design, so even if we are not careful when using water or other beverages spilled on the keyboard in the L412′s body do not have to worry about , because the back of the liquid discharge holes will help the computer to direct the liquid spilled out in the above, but will not enter inside the computer.

Summary

Strictly speaking, although the overall performance of the Lenovo ThinkPad L412 battery is not too much out of color, but its classic design and efficient performance, or to have left a deep impression. One Intel Core i Series ThinkPad processor makes a reference to the overall performance in injected new vitality into the overall execution efficiency can be improved, in addition to a fully integrated approach allows the heat to do the machine easier and more efficient. Although endurance whom we can not definitely, but because of Core i Series intelligent management processor or lead to a lot of make up, so the L412 can meet the overall performance of office business users need.

Data security and excellent service has always been advocated by adhering to the ThinkPad, so we need to see the back of a notebook with a more comprehensive value, rather than performance or price. For small and medium users, ThinkPad undoubtedly meet their requirements, and a new generation of L-series laptops will naturally become the best solution, which, L412 as the high price is worth the classic business notebook selection, reliable of.

Opened Mini 110 XP, black screen with white normal operating area is in sharp contrast with a strong visual impact. Overall design, Mini 110 XP did not use the Mini 1000′s style, but with the Mini 2133 closer. This is reflected in the design of the shaft was the most obvious.
10.1-inch LED backlit screen resolution of 1024 × 576,16:9 proportion of gold in line with the proportion of human vision. 92% of the full-size keyboard keycap followed from the Mini 1000, Large Cap, ergonomic design and fit refers to the surface of the key gaps and key moderate way, are so small series that is the Internet in the most excellent keyboard. Iconic touchpad and mouse buttons without any change, I believe that this design has long been familiar to readers.

HP Mini 110 XP and interface details

This is the Internet standard 1.3-megapixel camera is not in the Mini 110 XP also absent from the upper right corner of the screen with the microphone, the user can provide the most complete audio and video applications convenient Internet experience.

HP Mini series of keys and wireless network power switch has been the Internet’s most unique, because it uses the push is not common, but the lever switch, always use to give people a different kind of experience.

The power button and switch between wireless networks is the hard disk and power status indicators, as well as Mini 110 XP speaker. Although the speaker hole is very small, but for the size and power HP Mini 110-1132TU battery are severely restricted access to the Internet is, how many users will not be too demanding of its sound performance, right?

As a netbook, Mini 110 XP interface is already quite rich, and the left provides a USB 2.0 port and 3.5mm headphone jack, the right side there are two USB 2.0 ports, multi-read card reader, VGA video output port and RJ45 network interface. Of course, Mini 110 XP is certainly ready for 3G, SIM card slot is hidden behind the battery.

HP Mini 110 XP battery and cooling

Mini 110 XP is equipped with a standard 3-cell lithium battery, a capacity 10.8V 28Wh, where the Internet is considered good in this configuration. Meanwhile HP Mini 110 XP also offers a standard 3-cell lithium battery, the HP Mini 100 battery XP to the more than double the battery life.
Despite the appearance of the Mini 110 XP style almost completely copied Mini 2133, but the design on the back there are a number of improvements. Such as 2133 with a one-piece anodized aluminum shell, so its back completely open, while the Mini 110 XP it into a modular design.

The benefits of modular design is that users can easily upgrade their own hardware configuration, while the modular design also allows the cooling effect has been strengthened, more cooling vents also allow heating elements heat to more rapid divergence out, to avoid the accumulation within the system .

HP Mini 110 XP performance tests

While the upgrade to the new N280 processor, but the netbook market remains a serious problem of homogeneous configurations, HP Mini 110 XP Edition battery is no exception. Nevertheless, we chose three performance testing software on the Mini 110 XP for some tests.

Summary

Overall, Mini 110 XP’s performance to meet some of the daily application definitely no problem, of course, if you are demanding big game, then it is very unrealistic. E-mail, web browsing, document processing is the Internet should be responsible for this matter.
Although a slight upgrade in terms of hardware is difficult to let us have experience in practical applications (see table above), but such a responsible industry giant Hewlett-Packard is still trying to bring us new products in a number of different feelings, such as the Mini 110 XP on the built-Syncables Desktop software to the HP Mini series notebook and other laptop or desktop computer can easily between music, pictures, video and other content simultaneously.

Our evaluation to the end here, since the reason for the prototype configuration, so we can not experience the many HP Mini 110-1014TU battery XP’s new features, such as high-resolution screen, such as high-definition video accelerator card, etc., but even so, Mini 110 XP classic design and excellent quality still left us deep impression. If you are a focus on product shape, and has very high requirements on the use of the consumer experience, then the HP Mini 110 XP can say is your best option.

And, ThinkPad X200′s keyboard and the overall model size a little larger ThinkPad T400, ThinkPad T500 series is almost the same, thanks to this widescreen LCD brings the body changes.

ThinkPad X200 is more compact than the ThinkPad X61, but can choose Montevina series CPU, SSD storage, 4GB of RAM and Intel Turbo Memory, have made to the X200 can easily meet most users’ computing requirements.

Design and Appearance

Describe the appearance of any Thinkpad series notebooks do not need to use other words, very simple, one word, black and if you think this would be improper, you should immediately choose another notebook in addition to the usual black appearance outside, ThinkPad X200 also Many of the improvements.

ThinkPad X200 ThinkPad X61 relative improvement is most impressive, the use of the widescreen LCD, rather than the 4:3 ratio on the X61 screen is basically the proportion of the market to use ordinary notebook display is selling less rare, X Series also began to follow the laws of the market, this is Lenovo 42T4834 battery not very surprised, wide-screen notebook will be more compact appearance, and in a single screen can display more content in, of course, many die-hard fans will find widescreen black X series quite difficult to accept.

Other minor improvements include the red and the same old Thinkpad side mouse button, the black volume button, and the ThinkPad X300, like the power button, in addition to not light outside.

Work

ThinkPad X200 is a very strong ultra-thin laptops, its top and bottom of the fuselage with a magnesium alloy casing, the interior is an integrated roll cage structure of magnesium metal, the whole giving a firm can not be broken feeling, you will not find in any one place a little deformation occurs.

Thinkpad notebook, one of the signs of metal hinge structure will certainly not disappear in the ThinkPad X200, solid hinge design makes the laptop screen even in a bumpy car use will not shake, and the top of the screen in the two clips together securely locked when the screen on the cover.

There are two keyboard areas, as always, the liquid discharged accidentally spilled a small slot in the ThinkPad X200 breakfast of coffee on the upset might not be disastrous.

ThinkPad Active Protection System (APS) still can be seen on the ThinkPad X200, the notebook when the unexpected fall, APS through the built-in accelerometer to detect the presence of danger, take the initiative to make the recovery hard disk read-write head to a safe location to avoid unintended damage valuable data.

Also worth mentioning is, ThinkPad X200 back panel can be very easy to open, the most frequent upgrade hard disk and memory can directly open the baffle can be seen.

Input / output interface

On the ThinkPad X200, ThinkPad X61′s old PC Card slot is the new ExpressCard 54mm expansion slot instead, while FireWire 1394 interface has been deleted, while a very strange Lenovo 42T4835 battery thing is that you can select the SD card reader + no Modem or 5 in 1 card reader + Modem, 5 in 1 card reader why the Modem to be linked together and really can not figure out.
Keyboard and pointing stick

X Series ThinkPad keyboard in the ultra-thin notebook which has been quite outstanding, and because the increase in the width of the machine, ThinkPad X200 ThinkPad X61 not on the keyboard as a little less than the normal model, but can do a normal size, the actual on, X200 and T-series ThinkPad keyboard uses exactly the same keyboard, typing is no longer in need on the ThinkPad X200 ultraportable notebook as general as to be done accordingly.
As we all know, Thinkpad keyboard that is basically the best notebook, each key is independent, no matter how hard you are, the keyboard will not have a little bit of sink, you get each key Lenovo ASM 42T4541 battery is the simple satisfaction, and, quite quiet typing keyboard, without any clicks and carbazole say a word, even in a quiet conference room, lecture hall, you will not sound the type of harassment to others.

Perhaps most people are dissatisfied with the ThinkPad X200 does not touch the plate, but only pointing stick, of course, Thinkpad TrackPoint is very easy to use, but, accustomed to touch the plate may never be able to accept the fact that there is no touchpad . space bar mouse button below the key-way good, feel-class, and no annoying sound of the keys.

Screen

Kind of Lenovo ThinkPad X200 on the screen in brightness of 150nits from X61 to the 200nits, for the previous Thinkpad laptop screen is mostly complaining about the problem of insufficient brightness on the screen, Lenovo has finally made a corresponding improvement of .200 nits brightness is more than enough for indoor use, but if used outdoors, is still inadequate. ThinkPad X200 notebook is not some business with the ambient light detector, the user can manually adjust the brightness level.

Speaker:

ThinkPad X200 is a single-channel speakers, plus speaker location is in the bottom of the notebook, we can look at imaginative play ..

Performance

ThinkPad X200′s performance in terms of performance can be described as outstanding. It is the earliest we see one listed notebook Montevina platform, and the new often represent a good, providing more computing capacity, power and fever did not increase. Frankly, 2.40GHz dual-core cpu, Intel Turbo Memory, 4GB 1066MHz DDR3 memory coupled with SSD hard drive, such a configuration for the X200 notebook Lenovo FRU 42T4649 battery of this size is really a bit too far, but estimates No one blames him for the computer too fast. (to clarify, DDR2 and DDR3 are not compatible with DDR2 to DDR3 will not be able to upgrade a)

There are three optional ThinkPad X200 battery, namely 4-cell, 6 cell and 9 cell, our test machine using a 9-cell version of the Lenovo’s official documents, said 9-cell battery can last about 9.2 hours of use time, 4 screen brightness level (total 16), open wireless network, we put ThinkPad x200 vacant for eight hours and then use it on a one-hour network, and finally the battery life is 9 hours and 53 minutes and adjusted in all things to the maximum time, battery life can be maintained more than five hours long, basically do not need to go around when the user is looking for a power jack.

ThinkPad X200 power supply and battery are no other differences Lenovo 42T4696 battery in the X series, while the ThinkVantage (TP power management software) made some improvements, the interface looks a little more friendly, but older users may need some time to adapt.

Heat and noise level

ThinkPad engineers have once again put the laptop heat and noise standards improve, ThinkPad X200 and ThinkPad X300 uses the same type of fan owl design, this surprisingly quiet and efficient fans, maybe you do not care about fan design, But you will certainly make for engineers to Lenovo Thinkpad X200 battery whole body so cold grateful. our general ultra-thin notebook and excessive heat will encounter the problem of excessive fan noise, because the size of the notebook interior space is very limited. However, ThinkPad X200, and even if you put his hand on the ventilation openings, only to feel a little warm air only. ThinkPad notebook design engineers to other staff did a very good example, as long as there is a good design, ultra-thin notebook can also be very cold, so the user feel good, the system more stable.
Wireless link.

ThinkPad X200 supports a wide range of Wi-Fi Options: Intel WiFi Link 5100, WiFi Link 5300, Intel WiMAX / WiFi Link 5350 and ThinkPad 11b / g Wireless LAN Mini PCI Express. The built-in Bluetooth and Bluetooth mouse for frequent use Headphone users will be very convenient. X200′s wireless connectivity software also made further improvements, users can map a ring-like planet around to see the wireless connection while ThinkPad X200 also provides a built-in GPS system to facilitate the travel of people everywhere.

Environmental

Lenovo has been hard so that their products more friendly for natural environment, ThinkPad is the first personal computer by GreenGuard certified product, indicating that the ThinkPad X200 has been identified EPEAT Silver, Energy Star 4.0 requirements. Lenovo Statement compared to previous Lenovo Thinkpad X201 battery Thinkpad series notebook can be reduced by 25% of energy consumption. less energy demand, more energy output, very good!

Summary

ThinkPad X200 ThinkPad X61 is the successor to the success of its amazing battery life, excellent thermal and noise control are commendable place, while in a small space and equipment so that more powerful computing capability is impressive profound. ThinkPad X200 and the ThinkPad series has always been to maintain robust, no matter how much you do not care who their computer, ThinkPad X200 I believe can be stable and complete work for a very long time.

The downside is that it is not the same as the ThinkPad X300 with built-in optical drive, and do not touch the plate removed FireWire1394 interface, high-definition interface does not appear on the ThinkPad X200. All-black professional is not necessarily everyone will look like, For those who want their IT departments to support the iPhone for business people, ThinkPad X200 is not a good choice, because the appearance is not outstanding.

Overall, Lenovo Thinkpad X200 2024 battery ThinkPad X series is not for innovation, but still worthy of praise ThinkPad designers and engineers to perfect the work.

Advantages:
• Intel Montevia platform performance
• very cool and quiet
• widescreen LCD that can be done to the full size keyboard

• a variety of wireless options
• Built-in GPS system and camera
• unambiguous design, rugged.
