So I am listening to a CD on my G4 12" iBook and the entire thing on the bottom (minus the battery space) is very very hot. Not so hot I am seeing anything melting or flames, but hot none the less. And it is not just under the cd drive either- basically everyplace on the bottom that is not the battery. Is there something wrong and how do I go about checking things out. I have not been doing anything cpu intensive either - just surfing and email basically. thanks!
