Title:
A1342 shuts down immediately after power-on; Cuts off after half-chime
Text:
A1342 MacBook Unibody won't boot. It powers on fine, and even starts to chime but every single time, exactly halfway through the chime, it loses power immediately. This is about 3 seconds after hitting the power button. Optical drive cycles, chime starts and computer cuts off halfway through the chime. Screen does not light up. Happens on battery and AC adapter; battery does charge (adapter turns orange).
I've checked the logic board and found the slightest liquid damage, cleaned it off and still no success. I did try leaving the top case unplugged and powering on via the power pads, just to eliminate the power button as a culprit, and it still does the same thing. Fan spins up, chime starts, computer dies. Every time.
Any ideas?
