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

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?

Hello I am replacing the board on this machine. The board is in great shape, I dissabled the GPU with dosdude method and removed GPU Voltage coil. Only thing I notice is that I get airport proximity: 129°C per HWMonitor. Is this normal? Machine seems to work fine. Thanks

SMC Bypass same issue: LED501: ON LED502: JUST A LITTLE "SPARKLE" (DA UN DESTELLO Y SE APAGA) I will try to get anotherd card to test, in the meantime, is there anything else I could check?

I was able to get another PSU, now different issue: MB: 820-2828-A With graphics card installed: LED501: ON LED502: JUST A LITTLE "SPARKLE" (DA UN DESTELLO Y SE APAGA) PP12V_S0_MXM: 0.440V (DIODE MODE) PP3V3_S0: 0.310V (DIODE MODE) PP5V_S0: 0.353V (DIODE MODE) With graphics card NOT...

With the board disconnected I get 1.2V in one pin and 1V in another pin. With the board connected nothing.
