I just got my 2.0ghz Alu Macbook a few days ago and everything works perfectly well, the thing is that after day one the magsafe started to emit a low pitched electrical whistling noise. It tends to be there a few minutes after booting into the OS and then it turns down to almost unhearable, but I experienced it returning after a few hours of use and then disappearing again. If I move close to the escape key I can hear a crackling noise emitting from the magsafe. I'm not trying to be overly nitpicky or anything but I read somewhere that if it's doing that it would be a faulty Mag-Safe board or something. Does any one you guys know anything about this? I have the 14 days to return it as I bought it online from the Apple Store so if it's a faulty part that might die/break/ cause problems later I might have to.
