The mac had a liquid spill (keyboard was sticky), the previous owner cleaned the board and it was working fine.
when I got the MacBook, the board was clean and it was working just fine, I
reinstalled the os and when a customer came to buy it, it just died!
I disconnected the battery and plugged it back in and once again it started working fine, 10 mins later it went dead again...
Green light comes on and turns to orange after 3 seconds.
PPBUS_G3H is 12v
PPDCIN_G3H is 16.5v
PP5V_S5 is 12v (should be 5v?)
Missing rails:
PP3V3_S5
PP3V3_34
There seems to be a short to ground on PP3V3_S5, measured on C7592, I compared it with a working board.
The board looks clean with no burned components so I'm really confused.
Apologies if I have missed anything, I'm still learning.
