I have a late 2008 15" MacBook Pro, and it's been working flawlessly for me. However, I have just found that the screen, especially the right side, is warping upwards. The screen does not seal perfectly anymore with the body of the computer, and I am worried that the screen may be damaged or the warping will continue. Has anyone else had this problem? One contribution factor may be extended gaming on an uneven surface, but I don't think that it would make such a large change. And if this problem continues, is it covered by the extended warranty?
