Comment 59 for bug 440411

Personally I don't think this is going to be 100% resolved because I've noticed very similar behavior in Windows on the same box too. I've been testing this for a long time and it seems that after I boot up Windows remaining time of the battery shows around 5h. Then I do some heavy graphical processing (watching flash video, enabling and using Aero) and the battery life suddenly drops to around 2h. This state persist until the battery is completely drained. It looks like an Intel firmware bug to me and all effort to solve this on the Linux kernel side will be more or less a hack/workaround...
