Vista Hibernation Problem

[Guest]

I am running vista business, and have been using hibernate for a while now. I
was playing a game on battery, the battery went dead, and now, after resuming
on ac, my computer won't hibernate. The screen goes blank, and the hard drive
light is on steady. I don't hear any hard drive noise though. The computer
will just sit there like that forever. I have disabled all non microsoft
services and startups through msconfig. still nada. I deleted the hibernation
file, and put it back with the cmd option. Still nothing.

Thanks

This seems to only happen when there is a cd in the drive. (Far Cry)
Otherwise, it hibernates just fine.
