I got a 820-3462-A board that had liquid damage with no green light. I tracked down that PP18V5_DCIN_FUSE is missing (it starts at 1.27v and slowly increases til 1.5ish). I can't understand how the 18v gets activated from the charger, is that via the ADAPTER_SENSE line / U6900? I'm using an 85watt charger and the DC-in jack works on the donor board I have.
* Fuse F6905 is shorted just fine.
* R6920 is 47Ohm (as expected)
* R6905 is 10Ohm(as expected)
Resistance PP18V5_DCIN_FUSE to GND starts at 8k and slowly increases until 40k or so
Thanks! Sorry if this is a noob question.
