ZDNet: Windows 7 battery update: Still no conclusive findings
“Microsoft and its PC maker partners are continuing to look into battery problems which some Windows 7 users have said they’ve been experiencing. So far, there’s nothing new to report, Microsoft officials said on Friday, February 5, but their investigation is continuing.
It’s still unclear exactly what is going on — whether there’s a problem with the PC batteries themselves or there is something that could be fixed via a software update/patch. Reports about what’s happening are all over the map: Some are claiming they are getting less battery life with Windows 7 than Vista or XP. Others are saying they are getting false reports that their batteries are faulty. There are a variety of battery-related complaints, some dating back to before the final release of Windows 7, in the Microsoft TechNet forums.”
