Logic board? I/O board? Both?
The Mac was connected, via USB, to an external circuit running on A/C power, and an isolation transformer was not used when it should have been. Result: dead Macbook. No indication of any activity at all when power key is pressed or held. The SSD was fine, and has been moved to another machine…but I’d like to salvage the laptop if I can.
I’m prepared to swap in a new logic board, but do you have suggestions for determining if the problem is the logic board? the I/O board? both? Something else? TIA
Ist dies eine gute Frage?
