Do you get 7V aprox on pins 2&5 of Q6920?
Check resistance to ground on ADAPTER_SENSE line.
Check SMC_RESET_L voltage level.

Diode mode should give something. So either a broken trace to SMC or dead SMC.

Actually a broken trace is likely as there is also a pull-up resistor on this line, so if it is not shorted to GND the line should be pulled up to 3V42.
