Tenfold life-span laptop battery claimed by scientists

admin — Fri, 23 Jul 2010 01:51:54 +0000

Laptop batteries and movable phone batteries may well catch sight of a tenfold boost in the sphere of performance if a equipment breakthrough from scientists in the sphere of the US comes to realization.

According to researchers by the Massachusetts Institute of equipment, replacing conservative battery electrodes with folks coated with carbon nanotubes can drastically escalate the power to burden ratio compared to conservative lithium-ion batteries.

The scientists say they produced the powerful new to the job electrodes by on the other hand falling a corrupt material in the sphere of solutions containing carbon nanotubes with sure and no charges to achieve a steady film coating.

The consequence is an electrode with the aim of is other porous and contains other oxygen groups, which can lumber room a bigger amount of lithium ions.

According to the scientists, the energy output on behalf of a agreed burden of this new to the job electrode material was five era greater than on behalf of conservative capacitors, and the sum power release rate was 10 era with the aim of of lithium-ion batteries.

In the sphere of addition to their from head to foot power output, the researchers receive the carbon nanotube electrodes were highly steady screening rebuff substitute in the sphere of performance in excess of 1,000 charge cycles.

Although carbon nanotube production is now restricted to niche suppliers, several companies are gearing up on behalf of mountain production of the material.

How to activate laptop battery

The following conditions need to activate the battery handling:

1. Just opened a new battery.

2. For a long time do not use the battery, the battery from the computer store the state office, is re-opening of this battery.

3. A long time, do not use the battery from the notebook or laptop stand out of storage (more than two or three months), now re-enable this battery.

Activation of the battery processing method:

Activation of chemicals within the battery to maximize battery performance, need to repeat the charge and discharge the battery (fully charged and then fully discharge) three times. The so-called fully charge and discharge means: the normal boot order of 3% battery power to the battery (preferably a run out, can be divided into several times to power, but not interval too long), and then must immediately shut down the battery charge 12 hours.

Here stressed the need to charge the battery immediately, because even if do not use the battery will self-discharge to 3% when the battery power consumption, this time charging the battery if not timely, self-discharge phenomenon can easily cause over-discharge the battery The damage to the battery, over discharge lithium batteries is a major taboo.

Activation of the battery charging processing, office machine must be turned off. If the time machine office waiting, hang and so state, when the charge to 3 to 4 hours of green power status light is no longer beating, the machine will automatically stop charging the battery, so can not be fully charged battery. When the discharge to 3% of the electricity, the machine will automatically enter sleep mode immediately, and you should restart the machine, the machine starts the process off the bottom left of the screen click the button, so the machine off.

If the operation of all the details are mastered well, and the quality of your battery has no problems, you can activate the cell with good chemicals to maximize battery performance battery 以后 Ji Benshang each time the normal use of both can charge to 100%.

Windows 8 System Interface Details Screenshot

admin — Thu, 24 Jun 2010 01:33:52 +0000

According to foreign media reports, it has heard the news of the next generation of Windows 8 operating system, consumers are expected to update next-generation Windows operating system in 2012.

Italian branch of a leaked from Microsoft’s road map shows that Microsoft may release in the second half of 2012, Windows 8.In 2008, the first time we saw Windows Live Wave 3, we see that it’s similar with Windows 7 user interface, for example, it uses the overall light blue color, no style toolbar buttons, these have been in Windows 7 application; In addition, Windows Live audio and video production into the second generation Ribbon interface “Scenic” is also applied to the Paint and WordPad and other programs.

Microsoft observers Pthurrott known that this is not accidental, Windows Live Wave 4 of the interface is also very likely to be accepted into the next generation of Windows systems. In other words, today we have seen in Windows Live Wave 4, and will become part of Windows 8.

Another noteworthy place is, Windows Live Essentials Wave 4 highlighted the Segoe font application, Windows Phone 7 and related products (such as Zune) also uses the Segoe. This change is particularly prominent in the Messenger, on the whole, the style and Windows Phone 7 of the Metro is very similar to the interface. From which we can glimpse into the user interface of Windows 8?

Legend Windows 8 will be used this way to switch users

Windows Live Wave 4 of the interface was modified again, this time, all the Essentials Desktop components are used Scenic Ribbon interface, it is worth noting. Because the current version of Windows Ribbon used in Office 2010 than the version used in the lag, is introduced in Office 2007 version of the first generation. Office 2010 Ribbon interface used in the document using tags, is the third generation of Ribbon interface.

Laptop screen specific maintenance Cheats

admin — Tue, 22 Jun 2010 01:37:16 +0000

Using a new laptop to play games, watch movies, listen to music, it must be feeling very good, but do not happy too early, if you are not careful maintenance of it, it can be committed enough to you from the problems, now I would like to tell you to take care a very important component – display. The following I will give you some maintenance daily tips about notebook display.

1. Try not to use your laptop for a long time, just let your laptop have a rest, after all, it is an electrical machine, because of long time using, it will lead to LCD burned, while the LCD is permanently destroyed, you have to pay an expensive cost to replace a LCD, the reasonable arrangement of time using computers is a way of maintenance.

2. Try not to stay long time in one interface, it’s not good to fall asleep in front of the computer because of tied, so there will be a long period of time in the retention state laptop screen because LCD pixels to display a continuous interface will lead to overheating and causing some pixels within the burning, that is part of the damaged pixels using a longer time, we will see on the screen there are some black spots, looks are not comfortable.

3. Screen will be dirty after a long time using, such as: dust, grease, etc., you have to clean the screen. When cleaning the screen you should do it with some soft materials such as cotton and the like, and stained with a little water gently wipe the screen and avoid direct contact can not be too much water screen, water entering the screen will cause a short circuit and burn.

4. Some friends thought that it will be OK tnat the laptop is just put at home and is not been using, certainly not broken it, I tell you this is wrong, if you use the notebook not very often, in order to maintain good at it, you should start it for a while. Check the screen, if the first with a damp cloth to wipe clean, the place to get the temperature a little higher after the water evaporated to open the computer.

How to expand the memory of notebook

admin — Sun, 13 Jun 2010 03:49:52 +0000

For notebook computers, because most of its memory is shared to use, it’s responsible for memory, memory and all other storage features, so compared to notebook memory performance of the machine is more significant. But the purchase of notebook memory is not as desktops, most laptops are reserved for the two 144-pin DIMM slots, some do not design with integrated memory expansion slot occupied, while others have come to occupy a slot placement of memory. Because of its design tends to integrate more technology, so upgrading the memory to some extent restricted.

We buy laptop, when considering “light”, “thin” and other portable factors, but also the power and other beneficial characteristics of mobile use, in addition, the performance of heat dissipation also requires special attention. Accordingly, a good notebook memory also requires full consideration to these aspects.

In view of the small and light notebook computer step by step direction, so the space occupied by the memory slot will be getting smaller and smaller. This requires choosing the same memory capacity tend to be relatively small under the size of memory, so ensure you insert the memory on the one hand to avoid collision with other parts, on the other hand smaller memory also good to avoid electromagnetic interference between components and ensure the stable operation of the notebook.

From memory point of view, it is recommended to select a single large memory capacity. First, the capacity caused by the different speed memory embodiment be of great differences, will directly affect the performance of notebook memory, thereby affecting the overall system performance. Second, because of the reasons for the smaller size notebook, usually reserved only for the two expansion memory slot, and most laptops have only one memory expansion slot, while in theory, a single large-capacity memory performance will be reflected better than the two or more small-capacity memory performance. The current mainstream notebook memory configuration is generally 128M, but even better quality KingMax, 256M memory, the highest price notebook also only 1,500 yuan, so to avoid future size of a notebook memory capacity bottlenecks in the application, directly to the notebook memory upgrade 256M regarded as a better choice.

From power considerations, compared to the same memory capacity, if the memory chip less, we can simplify the external circuit board PCB, thereby reducing energy waste. And because different capacity memory chips not very different from their own power, high-capacity memory chip they can further reduce energy consumption. Thus, we have a buy a standard notebook computer memory – memory chips less choice.

Consider the problem from the heat, the working state of each chip, due to currents will produce thermal effects, due to thermal conductivity ceramic package itself is poor, is the chip temperature will increase by reducing the number of memory chips could be reduced each root memory state power at work, so less memory chip in the working state of heat will be lower, which will help heat dissipation.

In addition, the choice of laptop memory is different from the one of the largest desktop memory features: Choose a good brand of memory. After all, the laptop itself is concerned, the pursuit of excellence, its memory is no exception. From the price, the brand-name memory, the memory is often a little more than expensive, but the brand of memory apart from a good quality of protection, its after-sales service system has also greatly protect the investment customers. In the purchase laptop memory, also need to consider compatibility issues, but in all brand memory manufacturers website, we can access to compatible products table, the above listed compatibility testing by manufacturers of various brands and models of computers and computer accessories, notebook computers we can make, model to query whether a particular brand of memory compatibility issues, thus avoiding the need to carry laptop buy laptop memory trouble, and to our more relaxed and happy shopping.

Currently on the market mainly KingMax, modern, KingHorse, Kingston and other brands, but also a few more box office hits, the main push to TinyBGA Kingmax notebook memory package. In addition to its high cost, the main package because of its unique way in bringing high performance. Because the use of TinyBGA package allows a smaller volume of the structure to accommodate a larger wafer, high-capacity single-chip, also made smaller and thinner memory, only one third of common TSOP packages; the same time Tiny

BGA packages to make the fewest possible memory wafer covered by ceramic package to better thermal performance, integrated the previously mentioned performance requirements, it can be said TinyBGA packages are more suitable for laptop memory package. As the memory technology continues to evolve, TinyBGA package is expected to become a mainstream form of memory packaging and broad market access, further enhance and meet the needs of users. KingMax Another reason for popular secret is it a good after-sales service system, each with a laptop memory is a unique number and password, warranty card, consumers simply KingMax Chinese site is available after registration three-year free-for-repair and life-long warranty.

In short, both in the purchase laptop memory size, capacity, heat, power and the brand and after-sales service, you can make your laptop a more agreeable.

How to deal with in the computer with virus

admin — Mon, 07 Jun 2010 03:33:24 +0000

Viruses on the Internet is constantly on the run, as the computer connected to the network, even though we have done all kinds of precautions, but we cannot avoid viruses absolutely, they would have got too easy. Now we have learned mostly how to prevent poisoning computer knowledge, here we have to tell you about poisoning emergency treatment measures.

First, do not restart your laptop
In general, when you see unusual processes running unknown programs, or computer speed significantly slower, even if IE often asked to run some ActiveX controls, debugging scripts. So this time that now you may have been poisoned.
After poisoning and many people feel that the first thing to do is to first restart the computer. In fact, this is very wrong. When the computer after the poisoning, if the restart, then the most likely result in greater losses.

Second, establish emergency disconnect network.
As the virus attacks, not only to slow down the computer, but also destroy the data on the hard disk, but also may send out your personal information, viruses, etc., so that further harm. This was found poisoned, the first thing to do is disconnect the network.
More disconnected from the network approach, the simplest way is to run cable under the back of the computer aside, this is the best way altogether. However, in practical applications, we do not need this trouble, after all, went to the computer behind it is quite annoying God. If you install a firewall, you can disconnect the network in the firewall directly, without a firewall, you can right-click “My Network Places” icon, the pop-up menu, select “Properties” window, right-click in the open “local connection” set it to “Disable” button. If a dial-up users, then only need to disconnect the dial-up connection or close Moden equipment can be.

Third, back up important files
Poisoning is not to conduct an immediate anti-virus, I personally think that if the computer is not important files, how to operate it does not matter, I drive up the overall format reinstall. But if the computer to save important data, mail, documents, then the network should be disconnected immediately after the backup to other devices such as mobile hard disk, CD-ROM. Although to back up these files may contain viruses, but antivirus software virus scanning than when delete is much better.
Moreover, after the virus attack is likely to not enter the system, so back up important documents in a timely manner after poisoning is to reduce the loss of one of the most important practice.

Fourth, a comprehensive anti-virus
In no worries, we can carry out the killing of the virus. Avira should include two parts, one in the Windows system under a comprehensive anti-virus, and second, under the antivirus in the DOS. At present, the mainstream anti-virus software can often directly under DOS antivirus disk production. When the anti-virus, anti-virus software is recommended that users of the necessary settings. Such as scanning compressed package files, scanning e-mail, while handling the file that contains viruses, for example, can be set to “clear the virus” or “isolation” rather than direct “Delete Files” The aim is to to prevent important documents were removed because of misuse.

5, change the key information set
As viruses, Trojan horses are often in order to steal personal information for the purpose of carrying out a comprehensive anti-virus action, therefore, you must be a number of important personal information, such as QQ, Email account password reset. In particular, killing the Trojan horse was found is, in particular, need to make this work.

6, check the Network Neighborhood
If LAN users in dealing with their own computer virus, but also check whether other computers on the network also is infected with a virus. Because many viruses will attack after the other computer to the network to launch attacks. Own computer with a virus, most likely transmitted to other computers on the network. If you do not time to clean up, then most likely be re-reverse transmission.
Check method on each computer in addition to a comprehensive virus removal, you can install this type of virus, Kingsoft Internet Security firewall, if there are other computers on the network with a virus, the antivirus will not stop to block attacks, we only need Open the intercept of the log, which can be an IP address that sent the virus database, according to IP address and then find the computer, according to the above method can handle.

Gap between the original battery and OEM battery

admin — Mon, 31 May 2010 03:32:15 +0000

Typically, after charge and discharge for 300 times, the performance of laptop battery will be decreased, but many people prefer to buy expensive original battery but not to buy OEM batteries.
I have a friend like this around, I asked him why, the answer was: fear of problems. Expensive laptop, he would buy an original battery which has quality warranty, but will not buy the OEM batteries for fearing the bad quality cells.

This is a very typical answer, and if the purchase of low-quality batteries hurt his beloved notebooks and even cause accidents is indeed a depressing question. This will be completely disassembled an original IBM battery with a replacement OEM battery, the facts speak for themselves, to check that how is the quality of third-party replacement OEM battery. At the same time, we will introduce in the text interspersed basic knowledge of the battery and circuitry, specifically dedicated to love yourself DIY classmates.

Two batteries to be dismembered , IBM OEM battery and the original 6-cell IBM laptop batteries

Prior preparation, we need two batteries, wallpaper knife 2, the word screwdriver, a pry a piece.
Now all ready, hands split!.

Original IBM laptop batteries will be the first to be mutilated.

Battery closed beta is the gap where the greatest and there is no alignment, we will open it here.

With a wallpaper knife gently tilt here can, careful not to plan too deeply to avoid injury to the batteries.

Pry out from here, hardly managed to open the battery cover.
It is lifted above the state, we can see that this battery of six batteries and control circuitry arranged look. Classified according to cell media, which are lithium-ion laptop battery. Light weight, large capacity, no memory effect and so on.
Because the lithium-ion battery is almost no “memory effect” and does not contain toxic substances, etc, and now most of the more digital devices are used to make lithium-ion battery power, its price is relatively moderate, high energy density, its capacity is with the weight of the nickel-metal hydride batteries 1.5-2 times, and have low self-discharge rate.

This battery is a relatively common structure: laptop battery appears to be something of a box, which is in fact a number of “batteries” composed by series and parallel, in general, notebook batteries are used 18650 or 17670 batteries, the main because the two batteries have larger capacity, smaller size, are likely to cause the shape of the battery needed. We are now open for IBM battery is 18650, of which 18 representatives of diameter 18mm, 65 represent a high degree 65mm, Sanyo products.

Here the humble little piece of circuit board is also the power supply system of the laptop are crucial to do with. Because the basic lithium-ion batteries are 3.6V or so, the two batteries in series to double voltage; parallel voltage unchanged, but the capacity has changed twice. Such as IBM T series, capacity 4400mAh, voltage of 10.8V, the two values is the string from the six batteries and combination.

The information of original battery cells is not written in the skin, but on the printed batteries metallic cavity, the peeling skin to see.
Sorry about that, although the Sanyo is the batteries in is a good brand, but the piece of IBM original battery is only used Class B battery cells.

Well, we have made clear of IBM original battery internal structure, here we start dismantling OEM replacement battery.

This is the internal structure of the 9 cells OEM battery

From the exterior, it’s s similar to the original IBM laptop batteries.

The battery cells of this OEM battery is Samsung 18650, purple, marked ICR18650-26, in front of a model, the back 26 that a single volume 2600mAh, can be regarded as one of Samsung’s best cells.

Name: Samsung Li-ion rechargeable battery
Model: SAMSUNG ICR18650-26
Nominal Capacity: 2600mAh
Nominal Voltage: 3.7V
Diameter: 18.25mm
Height: 65.00mm
Weight: 50g
Density: 520Wh / I, 199Wh/kg
Charging method: constant current constant voltage (4.2V)
Maximum charge current: 1CmA (2400mA)
Maximum discharge current: 2CmA (4800mA)
Discharge Temperature: -20 ° C ~ +60 ° C
Charging time: 3hrs (Standard) or 2.5hrs (Rapid)
Resistance is less than 65 cents in Europe.

It should be said, although Samsung battery cells is not known as well as Sanyo, but at least the top Samsung battery cells is much better than the Class B Sanyo batteries.

Therefore, unless you have enough money to purchase original IBM battery, or it is recommended to buy compatible OEM batteries, it’s sufficient for most everyday’s use.

Notebook battery running time under XP is still better than Windows7

admin — Sat, 29 May 2010 02:32:24 +0000

This year in August, a foreign media in a notebook tested, the results show that the laptop battery life running under system installed WindowsXP is superior to Windows7 system.

According to recent foreign media reports, Microsoft released the final version of Windows 7, the foreign against the Internet in this of Dell Latitude E6400 Battery life, respectively Windows7 WindowsXP and do the test results show that the former is stronger than in the latter capacity battery life.

The three participants, notebook, Toshiba NB205 netbook in WindowsXP, the Dell PT434 Battery life of 9 hours, 24 minutes, Windows7 Replacement battery for Dell PT434 life, compared with under 8 hours 51 minutes, the difference in time between about 1 hour. ASUS EPC10008HA and HP Mini311 difference in battery life are close to the area 1 hour.

Text that Microsoft wants Windows 7 in the Internet market is better than the Windows XP, “but the result does not seem very good.”

Testers pointed out that although the same hardware test environment, but Windows7 WindowsXP and support in different drive, in addition, the online system, the manufacturer driver for Windows7 support and updates are relatively backward, so such an outcome, “do not have to much of a surprise. ”

Testers also noted that the test results do not mean that Windows 7 WindowsXP in performance than the worse, because Windows7 in support of family entertainment, with better performance, of course, the Dell E6400 Battery’s usage requirements higher.
