Came home from work today to find my iBook in mortal danger. It was sitting closed with the lid down on the sofa, as usual. But somthing seemed just not right. Then I realised the nice comforting sleep light was not blinking and it was humming a little. That's odd, I thought, as I went to pick it up. Then I nearly dropped it, it was that hot. The whole thing was really really hot, everywhere. I managed to get the thing switched off and cooled down really quick but I thought that the thing was now fried and a gonner. After it was cool, I booted up and everything was fine, to my great relief. I have since zapped the Pram, repaired permissions, forced the periodics and even done the prebinding(for the hell of it) But what on earth had happenned. I thought an iBook with its lid down must go into sleep mode. (there are no externals plugged in). I thought it had no choice about this. My girlfriend had used it a few hours earlier but only to surf the web and had closed the lid after use. (saw that myself). Why hadn't it gone to sleep or if it had, what made it rewake when it was closed?
