MBP fails to boot. Powers off before chime!
I restarted my computer Due to never before seen, odd screen tearing on the desktop while dragging windows. It then didn't startup after shutdown. I press the power button, the lid button power light lights up for 3 seconds and the optical drive makes it's typical startup noise... But after 3 seconds it just quits, completely powers off. And then I can repeat this indefinitely.. Now after a half hour i did manage to get my computer started up a it worked beautifully for 3 hours... Until I closed the lid to put it to sleep. I came back, display was completely off and the harddrive was spinning full speed (even while the lid was closed)... And I couldn't get it to do anything. Had to Hard reset and I'm back to square one.
After pressing the power button again, the Power light turns off, and it (the hard drive I think) makes a click and cheep sound, as if it suddenly powered off. No software has a chance to execute, I can't do any commands nor does the screen light up at all. This happens all before the apple chime. So it must be a hardware issue. I've taken the battery out (full charge) and unplugged it, pmu reset, tried pram reset...
Also. When I HOLD the power button down to boot... Instead of just being on for 3 seconds... It'll stay on (solid power light) for 6 seconds and then the power light strobes on and off really fast for an Extra 3 seconds then turns off. I've reseated the ram, swapped them around (haven't tried new sticks). Opened the top case checked for obvious loose connections.
I really don't want to pay for a diagnostic and repair. But I may be out of options. The nearest apple store is 4 hours away, does the genius bar do free diagnostic?
Is this a good question?
