I have a 820-01041 board that has minor liquid damage on the U3200/U3100 side of the board. I was getting only 5v on the charger and 450ma, which is high. I replaced U3200 and U3100, but still had 5v 450ma. I checked the board on thermal, and saw U9580 was getting hot. Replaced U9580 and got 20v, but all my AWAKE and SLPS2R voltages were pulsing. Checked on thermal again and saw U7660 was getting warm. Replaced U7660 and U7650 and now I have steady voltages on all my rails up until S5. I am missing PP3V3_S5 and PM_SLP_S5_L. I tried T2 firmware restore and it is recognized in DFU mode, but quickly fails and produces an error. Does this mean the PCH is at fault, or is there something else I should check first?
