On two occasions I've put my 17"macbook pro 2.4 GHz OS10.6.1 to sleep by going to the apple icon on the menu bar and selecting sleep, then close the lid and put the computer in my briefcase. However, it seems to awaken in my briefcase and start cooking to the extent that the fans are blasting and it's wicked hot! What is up with that?? I had a motherboard replacement a few months ago.
Macbook Pro, Mac OS X (10.6.1)
I've had the same problem. THing would get jostled just right and I'd get someplace with a dead battery.
