My MBP suddenly doesn’t turn on properly. The computer turns on, but to a blank screen. I hear the startup chime and the HD whirring. Also, after a few seconds the keyboard lights up. I took out the HD for testing, and everything looks fine. Any ideas?
Could be a GPU failure. The MBPs A1226 and A1260 use the problematic NVIDIA GeForce 8600M GT graphic card. If you don’t have video on an external monitor contact Apple cause your computer could be repaired free of charge via the Apple special Nvidia replacement program.
Try connecting to an external display, could just be a bad LCD.
