I put the laptop together already, but the gate drive voltage from ACDRV was a nice 24.7V as it should be, ACOK at correct steady 3.3V, ACDET at 2.7V....

Case closed, replaced faulty BQ chip, it was not driving the PQ100's gate at all. Replaced PQ100 preemptively as well if it turned out to be the cause of BQ's failure. Power rail sequence is now correct. Thanks for the support.

ACOK can't be 6V, it's pulled up to the +3VL rail only. It goes to 3.3V when I bypass the MOSFET and boot the board.

There is no PR112 or PR111 populated....

There is no short. When I bypass PQ100 MOSFET (connect drain and source together) I get the laptop to fully power up....

PQ101 is okay
PR100 is good (0.03Ohm)
PU100 pin 3 0V
PU100 pin 4 0V
PU100 pin 5 0V...

Hello,

Having an issue troubleshooting this board, it takes no current. PQ100 MOSFET gets 0V on the gate and does not open, when I short it out the laptop powers up. There is 0V on ACDRV from BQ24780, 0V on ACOK.

Now for the fun part, ACOK is pulled up to 3VALW rail, when I short out the PQ100 and power up the laptop, ACOK jumps up to correct 3.3V, as soon as I remove the short across the MOSFET it goes fully dead again. Now my issue is that according to schematic this is a circular logic, I can't have +3VALW without getting power to the PU1101 SY8386BRHC, but I can't...
