Seeking boardview+schematics for Dell G15 5515 Ryzen Edition LA-K453p

Motherboard: LA-K453p
Service Tag# 838W8R3

Computer is currently dead, 20V doesn't go beyond the first 2 mosfets as there is 0V on the gate. My next order of business would be to find the charging circuit, ie the charging chip.

It would be great if someone uploaded boardview+schematics for it.

Thanks.

Thank you. Do you also happen to have boardview?

I haven`t boardview.

The charging IC is ISL95522A. I am currently getting 20V on pin 17 (DCIN) but 0V on pin 16 (ACIN) which is supposed to have 20V on it without the battery attached.

Resistor PRB9 has 20V on pin 1 and 0V on pin 2. This pin is connected to pin 16 of the IC. So, I am not sure how that happens.

Based on the schematics, the only other component that can pull the voltage to 0 on pin 16 is PQB2 mosfet if PQB2_GATE signal arrives at this gate.

I suppose for testing purposes I can remove PQB2 mosfet to see if pin 16 gets 20V back.

I am seeking suggestions. Thank you.
