微軟開始調查 Windows 7電力問題
ZDNET新聞專區:Ina Fried 2010/02/03 13:22:02
微軟說他們已經開始調查,是什麼原因讓Windows 7使用者在電池沒問題的情況下,卻收到他們電池有問題的警訊。
微軟的一個代表週二在一份聲明上說,「我們已經和我們的硬體夥伴一起合作在調查,這看起來像是和硬體的軔體有關。」
這個問題中的警示訊號是電腦的BIOS會去判定這台電腦的電池是否需要更換。在某些情況下,這個訊號會出現,而有些使用者會收到這個警示,即便他們的電池完全沒問題。

Users Claim Windows 7 Has Ruined Notebook Batteries
Microsoft on Tuesday confirmed an issue related to battery problems affecting Windows 7 notebooks.
dedicated to Windows 7 battery problems started in June 2009, and remains active.
Users are complaining of battery issues, including premature warnings that the power is exhausted, as well as more dire demands to replace the battery.
Microsoft said that that the problem was in the Windows 7 tool that decided when the battery had been drained, or was unable to hold a charge. "We are investigating this issue in conjunction with our hardware partners, which appears to be related to system firmware (BIOS)," a Microsoft spokeswoman said today. "The warning received in Windows 7 uses firmware information to determine if battery replacement is needed."

Is Windows 7 wrecking notebook batteries?
Posted by Adrian Kingsley-Hughes @ 8:19 am
Microsoft has begun an investigation into a possible problem with Windows 7 that might cause poor battery life, and even degradation of the battery itself, on certain notebooks.
The idea that a bad OS/BIOS combo could be damaging a battery is very worrying because it opens up the possibility that this issue might not just be annoying, but could also be dangerous.
The issue, which was first reported by users on Microsoft's TechNet forum, seems to have been around since June of 2009, and not only affected the release version of Windows 7 but also the beta and Release Candidate builds of Windows 7. Users are presented with an error message that tells them that they should “Consider replacing your battery” because “There is a problem with your battery, so your computer might shut down suddenly.” Along with the error message, users are also claiming that battery life is being cut short. Some are going as far as to say that their machines are virtually unusable when powered by the battery.
If all that wasn't bad enough, some users are going as far as to suggest that the problem is in fact physically damaging the battery because reverting to a different OS doesn't restore the battery to its previous state.
Ironically, Windows 7 was touted as improving battery life.
The word from Microsoft so far is that it is investigating the issue and believes that the problem is down to specific system BIOS versions.
Note: I'm also getting unofficial word from several OEMs is that investigations are underway.
I've spent a fair bit of time going through the reports of this problem and it's hard to lock the problem down. The diverse range of makes and models of affected notebooks would, at first blush, seem to rule out this being a BIOS issue. However, a range of different systems can have the same, or very similar, BIOSes. Also, when it comes to features such as power management, BIOSes share a lot of commonality.
