I was able to get the board to go to 20V by cleaning up various areas of the board affected by liquid. Replaced C6700 and what I believe is C7234. I don't have a boardview for this and not even sure if this is 01598 or 01958 board for sure as I can't find a F'ing part number anywhere.
It appears I have good voltages according to the power sequence chart I referenced up through P3v3main_Pgood. I am not sure how to find P5VG3S_EN or PCHRTC_RESET_L as they don't seem to correspond to the 01521 boardview.
Board now takes 20V and eventually the wattage and amperage go to zero. If battery is plugged in the board cycles down to 5V and back to 20V every few seconds.
I tried connecting to Configurator2 but the device does not showup on the host machine. I asked customer and believe the target device has Catalina and matched accordingly but I believe it should still see the device at least regardless.
Please help!
