Hello,
This tablet has no power, no visual signs of corrosion or burned components.
I notice V_ALWAY_ON_IN on PD5501 and PD5506 is 12V.
But VDD_BATA_PACK on PD5501 is 2.05V when the charger is plugged in, after a little over 1 minute VDD_BATA_PACK goes up to 6.16V
FANG_PWR_F stays 0V.
+3P3VSB_REG is only 1.98V
+5VSB_REG is 0V
I cannot find shorted coils or coils with low resistance to ground except for the ones close to the PCH/CPU.
