So this is the worst time of the term this could happen. My 15" MacBook Pro wont start up. To preface things I bought it the summer of 2007. I didn't buy Apple Care because I have an extended warranty since I bought it with my Visa (good or bad I don't know) which is good till this June. I have had to replace the logic board before when it was still under Apple warranty. One of two things happen when I hit the power button: 1. There is no sound at all, nothing comes up on the screen and the "sleep" light comes on, blinks a few times then stays on but nothing else happens. 2. There is sound, nothing displays on the screen but I know it has booted up because I can change the volume level and hear it change. I am hoping someone has some idea what I should expect if I take it into either an Apple store (1 hour away) or a certified repair center here. Please help!
