computer had liquid damage
works completely fine on battery but will not power on with charger, will not charge battery
I don't see any obvious corrosion points and have finished an ultrasonic on the machine.
I am at a loss of what to check. I know the PP18V5_DCIN is very low but cant find anything pulling it down.
no green/orange light
Here are some measurements i took.
pin 1 and pin 2 of j7000 pulse to 24v then drop back down to 2-3 v and orange light when testing voltage
68k resistance from pin 1 j7000
r7012 68k
r7010 101k
r7011 10k
r7020 46.9
l7095 0
r8141 95k
pp3v42 pulsing from 100mv to 3.42v only when testing
pp3v3_s5 missing
PPBUS_G3H 290mv
smc_pm_g2_en missing

Glad to be here i have already fixed a board going through previous topics.
Thank you in advance.
