I remember having a recurring issue with my original 1st gen unibody aluminum iMac where I'd close it at the end of a lecture, but it apparently wouldn't go to sleep, so hours later I'd go to fish it out of my backpack and it was dangerously scorching hot to the touch and the battery was all but fully drained. I tried debugging but ultimately resigned to just shutting it down every time, which sucked so much. At least I didn't wake up on fire.
