I got one of the new aluminum macbooks on black friday and have no problems with it until today. I was doing a video chat with my friend and all of a sudden I heard a high pitch whining noise. I thought it was coming from his computer but I muted the sound and still heard it. It sounded like it was coming from the left side near the power plug so I unplugged it (btw I was at 100% charged.) It seemed to rev down like it was a fan or something but then it started again. I plugged it back in and still nothing. I gave up and let it whine for a few minutes and finally I ended up lowering the brightness and sure enough, it pretty much stopped. I put it down to 1 notch and it was gone. I quickly put it back to halfway and heard it again. So I guess when I unplugged it, the brightness fell from 100 to half and thats why I heard the the whine rev down. I let it sit at 1 bar of brightness for awhile and now the noise hasn't come back. Any ideas if this is a big problem? Should I return my macbook?
