    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!

    Are you sure it wasn't the fans ramping up their RPM's?

    It's the processor going in and out of a sleep state. All Core Duo/Core 2 Duo chips do this in laptops. My Dell D620, HPDV9000, Dell XPSM140, and Macbook do this.
