Voltage on PPBUS_G3H with just the charger and no battery plugged in?

12.3 voltas on ppbus_g3h with just the 85w charger and no battery plugged in

This would indicate an issue on the SMBUS data lines between the ISL and the SMC. Do a diode mode reading on pin 2 of both R5380 and R5381.

Expect dead ISL6259 or SMC.
