Ok, so I searched around and I have not found any posts about my particular problem. My MBP is fine, had the whine - fixed (but slow boot now), except whenever I turn the computer on, or wake it up, I get speaker hiss (sounds like tv snow) for about 5 seconds, then it fades away. Anyone else have this problem, also is it worth a return? Since it might be able to be fixed via firmware or system update? Thanks!!!
