Got a MacBook Pro M1 Pro 16'' to rescue immediately after liquid accident - I got it in less than 30 minutes after the spill.
It got spilled from behind when the laptop was closed. It mostly affected the rear of the mainboard and the bottom of the LCD.
I quickly took it apart and washed the liquid residue off the mainboard.
The area around the UP800 had some light corrosion, but it just washed away with some IPA. Other areas looked undamaged.
The mainboard got a thorough cleaning, as did the top case and LCD connectors / cables.
Now the laptop boots into OS only if the main LCD is disconnected.
If I leave it connected, it will power on for about 15 seconds and then reboot. No image on the screen whatsoever.
Sadly, I don't have another LCD to test, so I am not 100% if it is LCD or the mainboard that is at fault.
PPVOUT_LUXE_XW is 11.5V which it too low from what I can tell, but it might be just an indication of a bad LCD.
Any other tests I can do?
Customer is happy that their data is still intact, but it would be even nicer if the laptop gets repaired.
