Hi all,
I have a MacBook Pro 15" 2011 with an 820-2915-B board.
The laptop accepts power from a charger, shows a green light and the fan spins and then the machine immediately shuts off. This process then repeats over and over.
Can anyone help me in diagnosing this?
PPBUS_G3H showing 12.58V before and during temporary fan spin.
PP3V5 showing 3.35V before and during temporary fan spin.
PP5V5 showing 5.02V before and during temporary fan spin.
PP5V_S3 0V before fan spin and then 4.3V when fans spin, then back to 0V again.
