Fan on High???
Turned computer on today and fan is stuck on high. Computer has been OFF for 5 days. Computer is 3 years old and fan has never once come on,
Why now??
MacBook Pro, iOS 5.0.1
It may be caused because of different reasons. I recommend you to wait some minutes and see if fans decreases their speed. If not, reset the SMC > http://support.apple.com/kb/HT3964
If it doesn't work, I recommend you to run an extended test with Apple Hardware Test > http://support.apple.com/kb/ht1509 If you see an error at the end, copy it here
