"PPBUS_G3H = 1.2V (W baterry)"
I meant charger AND battery; not battery alone.
12.27V on charger alone, there is a communication problem between SMC and U7000.
Diode mode readings look good, post voltage on SCL/SDA too.
Be sure R7000 is good.
Try known good ISL6259 chip.
If still the same, change SMC.
