2007 MacBook Pro Wont Power On...
I have a 2007 Macbook Pro 15inch which had the Nvidia Geforce 8600m GT problem.
I followed guides to get the graphics chip working again.
when i first turned it on, it didn't do anything and took a afew presses of the power button to do anything.
When i finally got the computer to post, it would shut down a couple of seconds after the startup chime.
Sometimes if i was lucky, it would boot all the way up to OS X and then shut off shortly after.
Times when it dosen't turn on at all, it sounds as if the hard drive is spinning up and then dies after a while.
Is this a good question?
