i put my computer to sleep this morning, went to school, came back 11 hours later. the sleep light is off and not pulsating. the computer won't wake up, and it is burning so hot that i can barely keep my hand on it for long periods of time. i've had problems waking up before, but never this intense heat issue. i just upgraded to 10.3.3 today. wtf? this computer has given me nothing but headaches since getting it a month ago. are there any resetting things i can do to try to alleviate these issues?
