Last night I shut my macbook (white 2.0) down. I never close the lid till I see the screen go black. This morning when i went to grab my macbook to use it....it was HOT!!!! The white light on the side was on, I opened the lid and the screen was black, I tried to power on and nothing, I finally get it to turn on and immediatly read the core temp and it was 151 F. Well today I turned it off again came back to it 40 minutes later to turn it on and use it and the white light was on and it was hot again. What is going on?? Any suggestions?
