Hello. I have no experience on M1/M2 boards. I started to read and tooks the measurements below. Any advace will be appreciated. Wont switch to 20V. Takes 5V and 0.100A Same behaviour on Magsafe and both C ports MB looks clean. Couldnt find any blown component nor liquid damage. Diode...

Could I try to connect to ground Pin 11 of U8400?

How can I do that? Or measure that?

Do you have reference measures?

Can be issue with LID switch?

Replaced U8400/Q8401 and same issue. All resistor seem to be right.

Can I replace LP8548B1SQX06 with LP8548B1SQ_-03?

DFU Mode is returning 4014 error when reviving, (But yes, machine is recognized in DFU). I tried several times with different cables. Any help? Thanks

Just tested with known good display: same issue. Any other idea? Thanks

Hello. Received this macbook: Slightly liquid damaged around: CA780 (basically destroyed, I removed it) and U7100. It switches to 20.25V and takes 0.040mA and nothing else. Can you advise on what measures to start with?
