orange light 820-00165 not turn on

[andrespi]

this macbook not turn on fan, only orange light charger this measures
smc reset_l=3.3v
ppbus_g3h=8.59
CHGR_ACIN=3.9
PP3V3_S5=0v, not short

Any history available?
What about SMC_PM_G2_EN, PM_BATLOW_L?

 

[andrespi]

SMC_PM_G2_EN=3.3(sign enable u7501) PM_BATLOW_L=0V( what does this sign do? this sign activate s5?)
had a little corrosion u7501 but clean with flux, change u7501?

 

[2informaticos]

Post basic voltages for U7501; pins 23, 12, 13, 22, 29, 21.
Check exact diode mode to ground at L7520/60.

 

[andrespi]

pin23=8.58
pin 12= 3.3
pin13=0V modo diode 0.50
pin22=3.3
pin29=1.2
pin21=3.3

l7520=0.43
l7560=0.36

"pin29=1.2"
Diode mode?
If good, change U7501.
