Exact PPBUS_G3H voltage?
Check SMC_RESET_L and SMC_PM_G2_EN.
Check SMC_RESET_L and SMC_PM_G2_EN.
"PPBUS_G3H :18.49 Voltaj"
Are you sure?
Then Q7030 is bad.
BTW, use 45/60W charger for Air jobs.
Or 15V from lab PSU, if prefer...

Did you check diode mode to ground at L7220/60?
Post U7201 basic voltages; 23, 22, 12, 13, 29, 21.

Check U7941 for corrosion.
Post its voltages.
Post its voltages.
Change U7941.
Give it a try...
Did you try joining pins 2 & 3?
SMC_PM_G2_EN remains high then?
SMC_PM_G2_EN remains high then?
Always 0V, or pulsing?
Try changing U7201.
I changed u7201.
SMC_PM_G2_EN = 3.4 Voltage fixed
It was a fan return. It pulls at 0.62a and after 15 seconds it turns off and on again.
I tried SMC pypass mode. The fan is spinning at full speed. It resets again after 15 seconds.
I transferred the bios from the same motherboard, still the same
