MBP powers down after 4 seconds
My MBP shuts down 4 seconds after I press the power button. I had a very noisy fan for the last couple of weeks, got a new one from iFixIt, but haven't installed yet. I've tried most of the solutions suggested by the Apple Knowledge Base at http://support.apple.com/kb/TS2570: Safe reboot, PRAM reset, start from CD plus resetting the SCM. (I mentioned the noisy fan, because that's one of the symptoms Apple describes in its article on resetting the SCM at http://support.apple.com/kb/ht3964.) Until I tried them, I was getting most of the way to the desktop, then grey screen only, now 4 seconds of black until the power goes. Help??
Is this a good question?
