Hi,
i have this board 820-3662 who don't want to boot, I change already because U7190 is short (hole black on the component), I change too U7100, R7101.
Now I have PPBUS_G3H, Clean board, no liquid.
PP3v3_S5 and PP5v_S5 are present.
Missing PM_SLP_S5_L and SMC_S4_WAKESRC_EN which are required to enable S4 rails.
ppbus_g3h = 12.57
PP3V42_G3H = 3.42
PPVRTC_G3H = 3.34
PP5V_S5 = 5.04
PP5V_S4 = 0v no short
pp5v_s3 = 0v no short
pp5v_s0 - 0v no short
pp3v3_s5 = 3.34v
pp3v3_s4 = 0v no short
pp3v3_s3 = 0v no short
pp3v3_s0 = 0v no short
pp3v3_sus = 3.34
PM_SYSRST_L = 0v
PM_BATLOW_L = 0v
PM_PWRBTN_L = 3.42
PM_RSMRST_L = 3,29v
PM_SLP_SUS_L = 3.4v
SMC_ADAPTER_EN = 3.4v
SMC_PM_G2_EN = 1,15v not normal?
