When I got home today and took out my MacBook Pro (this is a 13-inch, mid-2009 base model), I noticed that was exceedingly warm. Funny... I had put it to sleep a few hours ago, didn't I? Apparently, the MacBook Pro had failed to go to sleep when I had closed the lid earlier. It was on. The LCD also appeared to have been damaged by the heat. The lower right corner, in particular, was much brighter than the rest of the screen. My Mac is basically out of warranty (bought it in August of 2009), but is there is anything I can do? This screen discoloration is off-putting, but nonetheless, I am thankful that the computer did not break down completely from this failure to sleep and subsequent overheating. Why did it fail to go to sleep when I closed the lid? It always did and does now. Some research indicated that keeping Firefox open when forcing it to go sleep may result in the computer not going to sleep properly... I'll keep this laptop for now, since it's operational, but my next computer might not be a Mac. Anyone had such an experience?
