Hello. This is my first post and my first mbp. So i have readed some posts about high pitched noise in MBP under xp/vista. But I also have some noise in osx also coming from right side of display (this noise is not so high pitched) and it goes away when you put display to sleep. Does anyone have it also? Can someone with new mbp test it. You can hear it when you put you ear close to bottom of display and then try to put it to spleep. If you have it,then you should notice it. I dont now is this software or hardware problemm. This noise start to come only when osx is loaded completle but when you have this grey start screen. Thank you very much.
