Hello, this is my first post

I need your help, I know I'm still very new but I'm learning I've taken a course but I haven't talked much yet.

I got a Lenovo IdeaPad 3 15ADA05 NM-C821

and it does not turn on nor does it load, in the laboratory power supply it marks 0A.

reached the PQ201, but it does not activate it and it does not go from there

I have been reviewing the BQ24780S, it is entering the 20v but in output 4 ACDRV it has no voltage, where can it continue Thank you very much I put some photos of the measurements on the diode scale

I forgot to comment, I have jumpered the PQ201 and the equipment turns on fine and works but does not charge the Battery
 
pino 4 ACDRV deveria ter uma tensão em torno de 24v.
Se você tem 20v no source e gate sua placa esta em proteção!
Remove PQ202 e veja se a tensão de gate sobe para 24v ?
boa sorte!

If in the end it was the PQ202, it was shorted, I need a lot of practice... since it didn't occur to me to check the next mosfet...

Thank you so much for help me!
