A1466 820-32-09-A no power


I have an A1466 820-3209-A that has green light, but no fan spin.

It takes 0.400 A no PSU and them drops to around 0.250A.

I think that I have a short on PPCPUVCCIO_S0_REG because on L7630 I get:

Diode mode =0.0216V and 11.90 ohm off resistance to ground.

Is this shorted or low resistance circuit?

Can you help?
R7981 has 20K ohm, and 3.3V on both pins, and C7981 isen't shorted (diode mode has normal values). I'll replace both just for sure.
