MacBook Pro Logic Board suddenly not booting
Basically, during normal operation of my macbook, not much CPU load either, it suddenly shut down. When I opened it, power delivery to the USB C ports was working, like for example, my mouse would light up, but the Mac itself won't boot, I then noticed a small buzzing sound coming from the top of the top case.
Around this area:
Here is a video recording that shows exactly how that buzzing sounded like:
The video might have caught some background sounds, ignore everything but the specific buzzing sound. This buzzing sound was always there whenever the logic board had any sort of power, if it was on battery only it would make that buzzing sound, if it was on USB C power supply only it would also make thag sound.
Another thing I noticed was that the logic board would always turn itself on whenever connected to power at all, if either the battery or power supply were connected, the buzzing sound would happen, then if I hold the power button to shut off the macbook, it would turn off normally, all power delivery to USB c would go away like normal but then 5 seconds later the logic board would go back to life again.
Following that I tried an SMC reset, after the SMC reset, now nothing works, doesn't boot, power delivery to USB c doesn't work, and I no longer hear the buzzing sound.
I would really like to not replace the entire logic board if possible, but if it comes down to it I would not have any problems, I am just inquiring in case there is a way I can solve this without replacing the entire logic board.
Thanks.
EDIT: I forgot to mention this, but I found a solution online that stated that I should leave the macbook for a while without any power, so I disconnected the USB C power supply, as well as disconnected the battery and kept it overnight, still nothing happened.
Furthermore, something I forgot to mention, I am 100% sure this is not a battery problem, as the Mac doesn't boot on the power supply alone either.
Questa è una buona domanda?
