I have a MacBook Pro running 10.6.6 - the hard drive recently crashed and since I've gotten it back, for some odd reason the screen won't stay off. I dim it all the way and 5 minutes later it will come back on. The only way I can fix it is if I turn off the "automatically adjust brightness" option. Is there another way around this? any idea why this is happening? It wouldn't really matter, but I go to sleep with the computer on and it ends up waking me up every night.
