Recently, from the major forums have found that many notebook users from Windows XP / Vista upgrade to Windows 7, found that the new system severely shorten the battery life, which the industry’s divergent views, but in some other system users to replace After missing the battery problem, which Microsoft has started investigation.

Official Microsoft TechNet forums, there are users post, said he put himself in 2007 bought an HP laptop to upgrade from Windows Vista to Windows 7, but the battery life but never became a mere two hours, half an hour, but Microsoft is repeatedly promote the new system can significantly extend the battery life time.

It is reported that Windows 7 is the root of the problem adds a new battery testing tool that can determine whether the battery needs to be replaced and inform the user, but in some cases, even though the battery business as usual, the system will judge whether the error that the battery has been exhausted, and recommended that users immediately replaced, and sometimes even directly shut down the system. Some users reflect the frustration that he did you are prompted to replace the old battery, but the new battery or continue to receive the same warning.

Microsoft also claimed that sometimes the new tool is working correctly, in other words, if it prompts you to replace the battery, it is possible your battery really has to be hung, but the chances of false positives is clearly too high.

We can only hold the onlookers on this issue, what exactly will cause hardware damage cited software, is still not clear. However, in this, we have collected it and sent specially from the Internet for laptop charging the right way for your reference.

Q: laptop battery needs to wait until all used up rechargeable power do?

A: In today’s era of lithium batteries, so the idea is entirely erroneous. This principle only applies to pre-nickel batteries. For lithium batteries, the battery ran out and then filled with a long time do not have any effect or even harmful. Because the lithium battery does not exist so-called “buffer effect.” Laptop battery life in general only with the man-made damage or natural lifespan. Basically, the battery life are fixed 300-600 charge and discharge times, for most people, you can use almost 2-4 years.

Q: When the power supply connected to the battery when you need to disconnect?

A: Many notebook users have asked this question, the answer is the need does not need to, depending on the actual usage. Connecting DC power supply without removal of the battery on the battery, and does no harm, because the battery is fully charged and then, after no longer accept any power injection, power will shift all of the direct power supply system notebook. But when the laptop high-speed operation, the internal overheating better to remove the battery, otherwise it is harmful.

Q: So what should be done correctly to the laptop battery does?

A: It should be possible to avoid the 0%, rechargeable battery runs out of light, as this will give the battery a lot of pressure to cause harm. A more viable approach is about 20-30% in electricity consumption when the remaining charge.

Edit Comment: From the experience on the use of mobile phone batteries, many people may feel exhausted all the laptop battery should be recharged. But in fact the notebook lithium batteries in the “light / charge” is a limited number of areas, and all used up rechargeable battery life will be greatly shortened. At the same time, the battery should be relatively dry areas for recharge Also note that the heat issue, which is the enemy of the battery.
