1. does this make this sound when you have it running on batterys?
2. do you use the fully earthed plug with a long cable or the little travel adapter thing on the power brick?

Its only happen to be a couple of times; I've heard it on HP, Compaq and Dell machines - nothing to worry about. Don't like the sound, turn up the music volume.
On my old Macbook Pro I used to get electric shocks (thus why i sold it).
I believe that was caused by improper earthing, and wondered if this could also be the issue with the current buzzing and bad sound on many macbooks?
