Hello all. I was wondering if there is a way to tell what the reason is that suddenly my fan in my Powerbook run on end forever. Its not even as if i'm doing anything on it and it will just come on and run for a very very long time. So long that i can see a direct effect on my battery life. Just as I am sitting here typing this it has come on, and nothing else is goin on other than me typing. They didnt used to do this... I'm wondering if its got to do w/ iTunes 5 because i've only noticed it since I upgraded to that. Any suggestions. Thanks.
