Asus G712L laptop does not charge, does turn on with battery.

[SarcasticOP]

I have a laptop that does not charge, but will turn on, so I believe this is in the charging circuit. I see not heat under thermal camera so no obvious shorts that are easily detectable from that. I am not too familiar with schematics and how to read them.

I know it is taking 20v in at the barrel jack connector, but since I am not familiar with this motherboard, not too sure how to follow power rails to nail down the problem.

Sorry I cannot provide more info, but I can answer questions if you have any.

Board: G532LWS Rev 1.3

Picture of the area with the DC-IN Mosfets and of the charging controller including surrounding circuit please.

Or are you able to find and measure everything on the base of the designations in the schematics?

Not super strong with reading schematics, I get lost pretty quickly.

Then picture of the charging controller and surrounding circuit too please. Should be a BQ24780S iirc.

Edit: And resistance between these two points please (Source and Gate) to start with.

So the DC-IN Mosfets are most likely fine.

Plug the charger and measure voltage at the following 4 points: ACDET, VCC, REGN and ACDRV. Pay attention to not slip with the probes.

All are showing 0v, everyone other than 3 is showing OL in diode mode.

If the charger was plugged as advised then there is something wrong at the very beginning of the power path.

Measure voltage and resistance to GND of these two points please. Resistance to GND measurements always without power.

Is the charger known good, of correct voltage and current?
