I've read over at http://support.apple.com/kb/TS2377 that the 8600M GT in the MBP has a flaw that manifests itself in the following manner * Distorted or scrambled video on the computer screen * No video on the computer screen (or external display) even though the computer is on Now I have an off color 1-5 pixel thick vertical line an inch from the right of the screen stretching from the top to the bottom. Would this be cause by the 8600M GT flaw? BTW it went away now. I dont know why it went away. It just went away. I tried 3 reboots and it was still there. But while I was typing this up it just disappeared.
