A1342 shuts down immediately after power-on; Cuts off after half-chime
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.
Esta é uma boa pergunta?
