BIT TWIDDLER Microsoft is investigating complaints that its Windows 7 operating system seems to eat batteries for lunch.
Complaints are starting to show up on various blogs where people are complaining that their batteries are going down faster than the Titanic. This is a bit of a problem for the Vole because Windows 7 is marketed with claims that it actually prolongs battery life.
The problem was first noted on Microsoft's Technet and it is not clear if the problem is that Windows 7 is actually destroying the battery or falsely claiming that healthy ones are clapped out. The problem has been around since the first Windows 7 RC candidate and has not been fixed.
Another related issue seems to have arisen where the battery is shown as having only five minutes left and needs a charge. The board has 350 posts but the only official answer was posted and approved by a Microsoft moderator in June, who said that Windows 7 had issues identifying certain batteries.
This was probably Brian Ehlert, a Microsoft MVP who posted on the thread that he went from having three hours of battery life on beta and RC builds of Windows 7 to about 20 minutes on the Windows 7 RTM.
One fix apparently is letting the battery drain completely outside of the operating system so that it is recalibrated. However this did not work for Ehlert, who bought a new battery.
Microsoft has said that it is investigating this issue in conjunction with its hardware partners. µ
