I am attempting to repair a HP 15z-ab motherboard board number DA0X22MB6D0 REV D. When the charger is plugged in, the white led on the charger port turns on and when the power button is pressed 3V/5V comes up but the suspend voltages don't come and the fan doesn't even spin.
I have checked for shorts on all the mosfets, I have checked for shorts on all the inductors, I have flashed the bios and I have replaced the 32.768KHz oscillator.
Checking around the EC I have noticed that ECRST# and ECPWROK are both low, however RSMRST# is high. Any pointers on what I should check?
Schematics and boardview attached
