History: board came in with no green light. No noticeable liquid. One cap on PP3v42 had a mark. Replaced cap and U7090 area. Now have green light
Does not get hot, does not spin fan or turn on.
pp3v42 - 3.4v
green light present
PPBUS_G3H = 8.15v = SMC not turning on ?
Tried a light SMC reflow, no difference.
PM_SLP_S4_L = 0v
SMC_PM_G2_EN = 0v
SMC_RESET_L = 3.4v
PP3v3_s5= 3.3v
PP5v_s5= 0.003v - is this important with PPBUS_G3H being low ? i assume that U7501 will only turn on with 8.5v and hence won't generate the 5v rail
Diode mode to ground on PP5v_S5 = 0.417v so does not appear to be shorted
Just wondering if anything else to try before replace SMC please. (i struggle with SMCs, sorry)
