i have a core2duo macbook and there is a whine coming from the left corner of the keyboard. i talked to someone and they said it was the cpu. i found a fix on here which was open photo booth force quit sleep then wake. also in reading on this i found this was a issue with core duo and not core 2 duos. was wondering if this is a known issue with apple (does apple say yes this happens), has anyone had this problem on core 2 duo, is there a permanent fix, and any other info. thanks.
