HP shows Intel next-gen chip future laptops

04 Jan

Hewlett-Packard has posted detailed specifications of two approaching Pavilion dv7 laptops furnished with Intel’s next-gen grimy viaduct central processing unit.

Though a quantity of details own been leaked already based on an Engadget loud noise, HP’s U.S. Result support pages (PDF) without hesitation inventory coming models taking part in all of their spec’d not in glory (see graphic below).
Intel is already shipping the central processing unit to PC makers, which process what time the fragment machinery is formally announced next to the Consumer Electronics demonstrate on January 5, systems spirit transpire taking part in the pipeline.
Solitary example spirit sport the underlying i7-2820QM 2.3GHz central processing unit, listed with an “SC turbo” drive too fast of 3.4GHz. Intel’s Turbo Boost machinery speeds up and slows down the central processing unit to optimize performance and power, in that order.
Any more example is listed with the i7-2630QM 2GHz central processing unit with an SC turbo drive too fast of 2.90GHz.
Both processors own a thermal envelope–aka, Thermal Design Power before TDP–of 45 watts. Typically, mainstream Intel laptop processors own a TDP of 25 before 35 watts. By and large, the advanced the TDP, the additional boil the chips can potentially churn out.
At the same time as HP has complete on preceding dv7s, a quantity of models show your face equipped with a SuperSpeed USB 3.0 seaport, taking part in addition to standard USB 2.0 ports. USB 3.0 can consign a conjectural ultimate throughput of concerning 5 gigabits-per-second, roughly 10 epoch the drive too fast of USB 2.0.
Systems are plus listed with well ahead Micro Devices’ ATI Mobility Radeon HD 5650 and Radeon HD 5470 graphics processors.

Super-lattice materials and fuel cell performance

26 Sep

U.S. Department of Energy’s Oak Ridge National Laboratory on July 31 that a kind of new materials with specific properties is expected to help people get more efficient fuel cells. Research articles published in the July 31 issue of “Science” magazine.

The new results from the combination of two crystals, can be greatly improved under the conditions close to room temperature ionic conductivity of the super-lattice material, Oak Ridge National Laboratory, Materials Science and Technology Researchers Maria Warui pull and Sidifenpan what makes it completed the structural characteristics of this new material determination.

Typically, the solid oxide fuel cells require oxygen ions allows movement to the anode from the cathode ion conduction material (or solid electrolyte). However, the ion is much greater than the electron, atomic-level space is still not large enough, the smooth conduction of the material allows ions. Meanwhile, the other fuel cell materials force ions often through narrow channels, rather than ions jump from one hole to another hole, so transmission efficiency is low.

The researchers used to determine the structural properties of new materials is the main equipment 300 Oak Ridge National Laboratory Perspective kV Z-contrast scanning electron microscopy, the resolution of close to 0.6 Amy aberration correction. Obtained by the electron microscope images, the researchers reveal new material has super-ionic conductivity is due to the unique crystal structure of layered materials. Varela said that through the microscope, “we can see the close-packed but still ordered interface structure, this structure provides a broad ion conduction channel.”

Varela said that the two materials with different crystal structure form a layered combination of new materials to solve the problem of ion channels. The reason is the mismatch of two crystal structures led to its junction deformation of the atomic arrangement has not occupied much space, resulting in a smooth transfer to ion channels. In the past, fuel cell materials are usually ionic conductivity at high temperature to the new materials under conditions close to room temperature, they have the ability to maintain the ionic conductivity. The researchers said that, in fact, the development of high temperature fuel cell technology, a major obstacle.

The new material, including the University of Madrid, including by the two researchers at the University of Spain joint research and development, new materials, they observed excellent ion conductivity, but with such a super-ionic conductivity structure of the material is not very clear. Oak Ridge National Laboratory personnel perspective using Z-contrast scanning electron microscope to help them get the answer.

How to charge your laptop battery properly?

15 Jan

During the the process of notebook using, we need no to deliberately charge the sony vgp-bps8 laptop battery to 100% state or fully discharged laptop battery to automatic shutdown protecting. The correct way is that charge the battery in 20% state and stop charging in 98% . If the machine has the power calibration procedure, when the battery standard-by time significantly reduced. Then calibrate the battery in time to active the protection circuit performance.

For early notebook batteries as Dell XPS M1730 Battery, really need to fully charge and discharge in order to maintain good battery capacity. But for the lithium battery is not necessary even it may damage the battery.

In fact the lithium batteries has a little memory effect. The lithium SONY VGP-BPS9 battery materials is very sensitive to the conditions as temperature, the use of frequency and so on. The battery will be aging after used for some period time (standby time reduced). The natural wear and tear is an important reason, and inadequate maintenance is another important reason.

A well-designed lithium batteries have a very good protection circuit to prevent excessive charge and discharge.As over-charging and discharging of the VGP-BPS8 battery will be the rapid reduction activity. Under the protection of protection circuit, the user fully charge and discharge the battery several times, in fact, impossible to achieve had “full” level.

Sometimes WINDOWS show that DELL XPS M1530 Battery capacity is 20% or more, you can use 30 minutes. But after used 10 minutes or less the machine suddenly automatically shut down. The reason is that the battery has been aging, the battery protection circuit can not monitors the battery real capacity. In the normal battery depletion, the protection circuit original parameters have been unable to properly reflect the actual situation of the battery

So power calibration procedure is to correct the benchmark protection circuit parameters to accurately reflect the actual capacity of the Toshiba PA3465u-1brs Battery. This correction process will often take two or three complete charge and discharge. As previously mentioned, fully charge and discharge will reduce the battery activity. It is not frequently used, usually once a month.

use laptop battery properly

13 Nov

Recent laptop battery quality is very lively discussion. Now the battery is really, as some articles mentioned in the same deep-fried into full timing I do not think so, for a long period of time, books of mobile task is to rely on batteries. Then we should do the proper use of batteries? Recent books battery quality is very lively discussion. Now the battery is really, as some have said the same article in full has become a time bomb? I do not think so, for a long period of time, books of mobile task is to rely on batteries. Then we should do the proper use of batteries?

1, for the first time to charge the battery if you want more than 12 hours?

Maybe you buy books inspection machine, the clerk will tell you first need to charge more than 12 hours in order to fully activate the battery. In fact now the battery needs? At present books are basically cell lithium-ion battery, and only then Li-ion Sony VGP-BPS8 battery only need such a long time to fully activate the battery. The books now are equipped with internal lithium battery management chip, as long as both ends of the battery pack voltage reaches rated voltage, the chip will be cut off the charging circuit, and then continue to charge only a waste of time and energy.

Second, use an external power supply when it is not necessary to remove the battery?

Many of my friends like to an external power source, the battery discharge hope that this will extend Toshiba laptop battery life. In fact, there is no need to do so, if the battery is fully charged, even if it does not remove the battery is not to cause the battery to overcharge the dell xps m1730  battery to the detriment of health, because there is a battery management chip escort it. And some books if you remove the battery, the hardware system not reach full speed running, you run large applications will be quite obvious when you feel sluggish. If you experience a sudden power outage, you have removed the battery, then there is no way the information is being processed in time to save the. On the contrary, if not remove the Apple laptop battery, you could easily save the information being processed. Negligible relative to the depletion of the battery, I believe that the information being processed in time to save for you should be more important to some bar.

3, the battery will be a long time without its unloading alone, is not able to extend the VGP-BPS8 battery life?

Some friends saw no need to use the battery when the battery remove the individual store, you can extend the dell xps m1530 battery life. In fact, this idea has a great one-sided. Because the characteristics of its own lithium battery is determined, in fact, lithium batteries, as long as what production line, the aging process has already begun. This may explain why a once electricity had not been charging the battery of books, why after three years will be completely scrapped. An objective point, like batteries and ink cartridges are a consumable, you can not expect the xps m1530 battery to the same hardware as the general books can be used for many years.

Fourth, books do not use the battery if a long time, it should be how to store?

Many friends in the office and at home using nothing more than books, which can be found more than two external power supply without battery-powered, and only go out when the battery. As a few opportunities to use the Dell Inspiron 6400 Battery may be a lot of friends how to store the battery and headaches. If you do not use the battery a long time, I recommend that you charge the battery into a retention of about 3 or so, and then use the battery impervious oiled paper wrap and store them in the sun can not be direct and cool, dry and ventilated the office can be. But I would like to remind here that these methods only slow down the pace of aging of the battery only and does not prevent it from aging.

5, books how long the battery charge and discharge time is better?

The Pavilion DV8000 battery charge and discharge many of my friends think that too many frequently will shorten its life, and a long time to maintain a high capacity batteries are also unfavorable, making many of my friends were puzzled. In particular, the use of the battery much friends, I think monthly cycle (that is, charging and discharging the entire process) one is better, so will neither lithium-ion activity and the accelerated loss of aging, but also activate the part of the activity is not very strong ions.

6, to what extent the battery discharge books should be charged?

Probably many of my friends think that books should all be discharged in order to charge the battery, which is erroneous books, one of the Dell laptop battery for daily use. Those days, because there is a serious Li-ion battery memory effect, you must charge at least filled with the impact on consumers. The lithium batteries are not the same, if every time you put the battery power completely finished, then you are still corpses soon as possible to the battery bar. We usually use the battery when the remaining 5%, we should charge the battery has. If the battery has aged very powerful, you can try all the shine of the battery power in order to activate the part of the capacity. However, fully discharge or depth of discharge (refers to the power into the 3% or less), but the number of books should not be too frequent this would further accelerate the aging HP laptop battery.

7, the battery for batteries, OK?

As the original battery price is very expensive, and some friends, etc. After the iBook G4 battery end of life will choose to replace one of the batteries, the battery re-used to achieve the purpose. Replacement batteries for the thing, I personally think that can be said that eyes of the beholder, the wise see the intellectual things. Batteries due to China’s current chaotic market, a large number of pseudo-core, the secondary core flooding the market, so a good business to find a good replacement of the Acer Aspire 3000 battery is really a very easy matter. For improper ranging from life is not long, heavy explosions were caused by laptop batteries. I centered myself looking from another in this cell batteries, not easy to find a reputable merchant, for a large-capacity Sanyo batteries. After charge-discharge cycles, is still in use so that I very satisfied. Guer the best we have to replace the batteries more than the prior inquiries, looking for some good word of mouth business is important. Abundant in the budget situation, I still recommend choosing a size larger, brand better on batteries.

Dell XPS M1730 Laptop Battery Tricks

06 Nov

-if used primarily on AC power, leave the xps m1730 battery disconnected except to do a charge/discharge cycle every month-ish -store the Dell xps m1730 battery with ~50% charge (not exactly sure why) -try to let the m1730 battery discharge at least every so often (as opposed to constantly charging when half full)

1. Leave the dell xps  m1730 battery in. In case of power failure the battery takes over. Leaving it plugged in causes no harm to the battery.

2. Store it full.

3. Cycling is not necessary.

1. Turn off Wi-Fi and BlueTooth – Most laptops have shortcut keys to instantly disable wireless networking.

2. Don’t play computer games, music or DVD movies – Multimedia activities drain laptop batteries.

3. Disconnect all external device like PC Card modems, Firewire, USB devices and optical drives. Use the notebook touchpad instead of an external mouse.

4. Adjust your screen brightness – Dimming your display saves battery power.

5. Tweak Windows Power Options – Choose a Laptop power scheme that turns off the notebook monitor and hard disk after 10 minutes of inactivity.

6. Decrease or mute the Laptop Speaker Volume.

7. Turn off all scheduled tasks.

8. Turn off Auto-save features in Microsoft Office and other applications.

9. If your PC has a built-in wireless card, turn it off or disable it when not in use. 10. Programs that are run from a CD or DVD can be copied to and run from the hard drive, which typically consumes less power than an optical drive.

* 1 – All electronic machines have a lifetime, the more you use them, the quicker you exhaust them. Laptop batteries are the same. It doesn’t matter how much you care, laptop batteries will lose performance by time passes.

* 2 – Natural aging. Even if you put laptop battery away and never use it, Dell xps m1730 battery will die one day. Let me explain things a little bit more. You have to understand that, it doesn’t matter how good you care about your laptop battery, it will lose performance and one day it will die. Of course, your exploits will slow the process of aging of your battery. In warmer environments, while the laptop is used and your battery gets warm, your battery will drain energy quicker. For this reason, the number one rule is: Keep your laptop cool.

Try to keep your battery in room temperature. But don’t put your battery in a freezer or refrigerator. That will make your battery useless. The second most important point is, each filling-emptying cycle (or use) of battery will reduce performance. Of course this is not surprising. However, according to the time when you compare to the first use, it will surprise you. When users continually keep the battery pinned and connected to the electricity battery will continue to charge and discharge process. If you use a full charged battery to at previously working warm laptop, will be discharged quicker than normal. Once a predicted level charging falls (is different for each company) to provide the current laptop battery, AC adapter fills extra electricity.

Dell Laptop battery for the increasingly old, self-discharge is connected to and depending on use, will gradually increase. Normally lithium ion batteries will perform a 600 to 800 charge/discharge cycle. This means a life between 1,5 and 3 years. As described above, when you use your xps m1730 laptop battery, re-filling source (AC adapter) will remain unnecessarily pinned. As a note, most of laptop users think it is the best to fully charge the battery after fully discharged. But this case is for Nickel Cadmium (Ni-Cd) battery method. Today’s batteries have different chemical reactions and have different characteristics.

The best charging method is when lithium ion batteries occupancy rate is between 10% and 20% that’s the best time to be filled again, the healthy way to slower your capacity reduce. To charge Dell xps m1730 battery when it is fully empty, this is an old method and a wrong belief. Windows operating system warn us to plug in adaptor when it’s the best time to charge your battery dell xps m1730 (10%, 20% etc.).
