So I was enjoying my new 2.2 Ghz, and about 5 or 10 minutes after bootup, I noticed a high-pitched squeal coming out of the left side of the notebook, near the power adapter. I got really annoyed and kinda worried, becuase it was realy bothersome. After a couple of minutes it stopped. I read that this has something to do with the two cores of the processor? Is this a problem that I should get fixed/complain about at an Apple Store? Will it come back? Thanks in advance for any replies!
