My wife just scored a 2006 mb pro core duo for next to nothing so i really can't complain....but i was told it has just been sitting closed for years...the screen looks like it has a yellowish dingy tint around the edges (about 1-2 inches all the way around the screen)...I would assume its because it has just been sitting for so long without being opened...is there any kind of fix for this or do we just live with it as is....
