Windows7 injury laptop battery,Microsoft is under investigation

There are many laptop users from Windows XP/Vista upgrade to Windows 7 then found that the new systems serious shortened battery endurance.

In Microsoft TechNet BBS, an official users to post said, he put himself in 2007 buy an HP laptop from Windows Vista upgraded to the Windows 7, but battery 3000ibs but from two hours became just half an hour, Microsoft is repeatedly propaganda new system can greatly extend battery 3000ibs. Online BBS in other countries also have the similar questions.

It is reported, the root of the problem is that Windows 7 added a new Dell Inspiron 6400 battery measuring tools, can judge the battery needs replacing and notify users, but in some cases, though, the system will battery business-as-usual misjudgment, think battery has exhausted, and recommend that users replaced immediately, sometimes directly closed system. Customers have reluctantly reflect that he saw hints indeed re-edited with old battery, but new batteries are still continue to get the same warning.

Some say the problem in early July Beta testing phase Windows to exist, but also some say the official version of RTM just happen. A user to post said: "in installation RTM version 7 before my Dell xps m1330 battery Windows has been very normal, use time in my installed all Beta and RC edition can adhere to nearly three hours. Now, just about twenty minutes Windows 7 will bring my notebook to shut. The situation is in me from the RC steering RTM appeared. Needless to say, I like everyone very upset."

Microsoft said in a statement has been aware of the problem, and points out and Windows 7 read system firmware about the way, in many different types of manufacturer of notebook do exist. Microsoft said: "we are with hardware partners to survey the problem. Windows 7 to judge by the firmware information need to change the Dell Studio 1537 battery. But we are working with partners troubleshooting source, obtaining required information and guidance after will TechNet) in (BBS update."

Microsoft says, sometimes this new tools are working properly, in other words, if it prompts you to replace batteries could be your Dell Latitude E5400 battery has really want to hang, but clearly the misstatement risk is too high.
