i have 820-4924-a water damage has green light but doesn't turn on. I started measuring around and i'm missing PM_SLP_S4_L so i watched on one of louis videos with similar problem so when this signal took me to the PCH i checked for the voltage that powers the PSH -- PM_PCH_PWROK and that took me to U1950, and there i have voltage on pin 8 (PP3V42_G3H_CSPWRGD) and pin 2 (CPUVR_PGOOD_R) and the important signal im missing is pin 1 (ALL_SYS_PWRGD) so i tried to find where this signal comes from and that took me U8160 and that component doesn't exist on the board just empty pads. This shit is confusing. Any ideas ?
