Hi

Recently I found out there is buzzing sound coming from the left side of the speaker of Macbook Pro. I have checked and it is on going issue with the Macbook Pro. I am wondering whether I can send back to Apple service center to get it replaced? Need to check with them next Monday. Please advise.

Almost every MBP has this problem. It buzzes whenever the processor is not doing much, if you open up an application the noise goes away for a short while. I believe this can be solved with a future firmware update 'cuz there's no buzzing when I'm using Windows XP, so it must be a OS X thing. Well I hope so.

happened to my sis's MBP as well.We restarted and it was fine
