It is ironic that Microsoft’s claim that Windows 7 will improve battery life is being countered by some users threatening class action lawsuits due to W7 ruining laptop batteries. At least since June 2009 (Windows 7 and the battery error “consider replacing your battery” –Microsoft Technet) testers were reporting this problem. Yet it continues, with claims, counter-claims, and finger-pointing. A couple of recent articles: “Microsoft probes Windows 7 battery problems” and “Windows 7 battery update: Still no conclusive findings“.
BTW, I always thought those “I’m a PC” ads were stupid. I’m a human and running Linux on my PC was my idea.
