I've had my powerbook for about a month and a half. Everything has been great with it, but for the last week I can't get it to stay asleep. I have it hooked up to a moniter and in the middle of the night it wakes up and wakes me up when the screen comes on and is really bright. Also when I come home it is awake when I put it to sleep before I left. Previous to having this power book I had another one for 2 years and had it hooked up to the same set up as this and never had this problem. I've tried to look through system prefernces, but I can't figure out what would trigger the computer to come on at (seemingly) random times when I have put it to sleep. Any advice?
