Hi there. Got my 2Gb MB White, and Ive been quite happy with it, except for the common heat issues we all have. Anyway, I have just recently discovered a high frequent buzz that keeps going in the background, and the strange part is that when I keep the left mousebutton down it goes away. When I release the button it starts again. This happens regardless if its charging or without the power cable connected. I dont have super hearing, and its starting to become annoying. Anyone else with the same problem or potential solutions ? It starts to make the sound from the moment I first turn it on and is not warm, so I dont think its the fans kicking in.
