    I am running Vista Home Basic SP1 on my 15 inch 2.66 GHz MBP, 4GB Ram, 320 GB HD, 512 VRAM 9600. Lately, while playing Dragon Age Origins especially, I have noticed that my battery slowly drains over a period of hours (despite the fact that it the computer is plugged in). Eventually, the battery totally drains and the computer shuts off. However when I boot into Snow Leopard, everything works fine and there is no issue with the battery at all; it charges fine and maintains its charge while plugged in. Obviously this is a Vista software issue and not a hardware issue. Anyone have or know of a fix? Will SP2 fix this? Thanks a lot...

    You wouldn't happen to be using the wrong MagSafe power supply?

    I have this happen when I use the 65 W supply that came with my MB on my MBP and run something that goes all out. This doesn't happen if I use the larger supply.

    If you are using the 80 W supply, perhaps it is defective and needs to be replaced?
