Comment Vostro battery murdered by 7 (Score 2, Funny) 206
Just chiming in to say that this issue is definitely real. My Dell Vostro battery was about a year and a half old when I installed Windows 7 the first time. When I finally decided to switch fully to 7 it only took about two weeks before I unplugged my computer and got a message that my battery needed to be replaced. The battery until then had about an hour and a half of time on it running the 'balanced' power setting. I noticed the message maybe two to three minutes after unplugging. I was planning to buy a new battery, but if this is real then I hope a class action is in the works because I need a new battery, and this is obviously the reason I need one. Also, since installing 7 I should point out that my battery now only has a seven minute life off ac power, even under Ubuntu 9.10, 8.04, and Windows XP. In response to someone mentioning 'high performance' being the likely culprit, I only ran high performance power management while on ac power.
