I have a MBA 13" 2020 820-01958 that was pulsing on 5V_G3S and P1V8_G3S power Rail. Also pulsing on the enabled PIN on U7650 PIN4. Pulsing on P5VG3S_EN R7613 PIN 1. Anybody has the same problem? any idea was causing the power rail pulsing. I don't see shorted on the board. Thanks

Hello everyone!
I have this board that got slightly water damanged and it is stuck at S5 state. It pulses once every 5 seconds.
When connected the magsafe 2 to the bench psu, the current goes from 0.02A to 0.10A when is pulsing.
When using the genuine magsafe 2 charger, the light turn on and it became green and then amber. The fan is not spinning.
When I tried the SMC bypass mode, the fan spins a quarter every 5 seconds and the pulsing is still present every time the fan spin.
The pulses are present in the CPU Vcore rails on L7320 and L7310.... -
