Do I need a new logic board?
How can I be sure the logic board needs replacing. The computer wont boot and I know the power supply is good.
Does the battery have any charge left?
If not, there's a small possibility that the left I/O board is fried.
I've fixed a MBP that cannot boot at all, and all is well after I changed the left I/O board.
It's the one that contains the magsafe connection, USB and audio I/O interface.
