820-2915-B Not power on

[2informaticos]

Boardview file shows another package for Power FETs; not only for this board.
But voltage power rail corresponds with schematic.
What's not clear then???

If you are not clear with Q7820, then check PP3V3_SUS anywhere else.
If PM_SUS_EN is present, 3V3_SUS should be too; just need confirmation, to discard any Q7820 issue.

820-2915 boardview is missing a lot of net names. Use schematics to find pins and signals.

I checked it on pin 1 of R1847 3.3 volts stable

Trigger SMC_ONOFF_L and check for pulse at each big coil; at same time when trigger the signal.
