I went to open my Macbook which had been closed and sleeping for a few hours, and the bottom was hot. Which normally doesn't happen, as sleep mode SHOULD kill the processor. I opened up the laptop, and it didn't return from sleep mode. I starting hitting keys, and nothing. I was forced to retarted the machine, but now when I open it doesn't return from sleep mode as quickly, and if I don't open the cover all the way I have to hit a key on the keyboard (moving my finger on the track pad doesn't work) in order to make it return from sleep. Any ideas?
