I've tried trashing the com.apple.PowerManagement.plist and the com.apple.AutoWake.plist and restarting the computer right after, multiple times. Yet it still brings up a message that says something like 'This computer is scheduled to sleep at 8:40 and will go to sleep in 10 minutes if nothing is done'. I have NO schedule for it to sleep!!! And it's always around 8:40 pm, sometimes it's a few minutes after or before that time (so I can't even set up a counter wake up schedule for it because the time varies). When it goes to sleep, it disconnects me from a game I'm playing (that takes up the whole screen and can't be minimized) and it pisses me off. Please help!!!!
