Re: A2442 (MBP 14" M1 Pro/Max) Boardview and Schematic

Also hoping for a schematic and board view for the A2442.

I have a water-damaged model that randomly shuts down every 20 seconds or so!

Have you found the issue? I might also have a very similar issue with A2338, the battery charging sign comes up then the Apple logo comes up for 2-3 sec and shuts back down. can't able to find the issue. I am getting good readings all over the board. A little help would be nice. Thanks!

What is the condition of the battery? What is the history of this unit?

Are you using the official or proper rated power adapter?

If available, test with another known good battery. You should be able to find them on Amazon and return it if not required.

What is the USB Type C meter readings for this board? 20V? Current draw?

What is the voltage to ground reading for:

I2C_SMC_PWR_3V3_SCL
I2C_SMC_PWR_3V3_SDA
