I have grafical problems with my mbp (SR 8600gt) and thought I had problems with the screen or the grafic card (8600gt - known program). Here are som pics of the problem: http://i44.tinypic.com/15xx3du.jpg http://i43.tinypic.com/b6znef.jpg After the problem the screen goes black and I must restart the computer. I connected the mbp to an external screen and the same problem is displayed there. I went to my AASP and thougth they would fix it (since the nvidia-program is prolonged to 3 years). They said that the problem is "problem with power supply to the logic board". I've never haid problem with the power supply. It loads and runs well with power supply and there is no other signs of power supply problems, just the grafical ones. Does anyone heard of this problem before? Is the problem caused by me or is it a factory-made fault? In sweden we have laws that give us right to repair factory-made problems.
