In the top left quadrant of my screen, I have what appears to be a white spot, the sort that plagued Rev A Powerbooks. It's most noticeable on a light grey background -- in particular, the grey left border of Macrumors threads (thanks a lot, Macrumors ). It looks like there may also be a white spot forming in the middle of the screen, though this is not as "bright" as the one in the top left area. Though I have a Rev C, I checked out http://www.apple.com/support/powerbook/displayprogram/ anyway, just to see if my white spots matched up. The middle one does, but not the on the top left side. So anyway, I was wondering -- has anyone else had white spot issues with Rev C Powerbooks? Are white spots something that just happens? Might I have done something to cause the white spots?
