MSI PULSE GL66 motherboard MS 15811 ver: 1.1 charging issue

Actually I didn’t find any schematic.
This motherboard works with power supply only.
It comes with BQ 24780 replaced by someone and I have to fix some pads.
Mosfet missing in the picture goes shorted just connect the battery.
Seems not component shorted.

Hello!

Your board seems spilled - some components are corroded:

All corroded components must be replaced. Check the whole board for more corroded components.

Hello
I replaced corroded parts.
How can I test mosfet zone, because I can’t insert mosfet and it goes shorted every time.

Replace both transistors - PQ36 and PQ37 regardless of whether one of them seems functional or not.
Then measure the voltages to ground on all pins of battery connector and on pins 1, 4, 5 of transistor PQ33 in the following cases:
a) Power supply connected only (without the battery).
b) Battery connected only (without the power supply).

I replaced both transistors
Battery pin with battery connected

Pin 1-2=9 ,63V
Pin 3= 0V
Pin 4= 3,3V
Pin. 5= 3,3V
Pin 6= 0,3V

PQ33 Mosfet pin Battery only

1-2-3 =- 9,63V
4= 0V
5-6-7-8 = 9,63V

With power supply only motherboard auto power on.

Battery pin

1-2 = 0,33V
3= 0V
4= 3,3V
5= 3,3V
6 = 3,3V

PQ 33 Mosfet pin power supply only

1-2-3 = 19V
4 = 19V
5-6-7-8 = 0,33V

Replace the battery.

Should the circuit be ok?

Yes, it seems the board is fine.

Ok laptop now works with battery, but after connecting power supply mosfet is shorted again.
Now is shorted after 3 minutes with battery and PSU connected.

Please, post a clear picture of marked area of the board:

I have rebuild this line from chip to gate of PQ37 as I didn’t find right schematic I found it to a similar schematic

The marked three components seems corroded and needs to be replaced.

Ok
I replaced corroded components and shorted mosfet
Now how can try motherboard to avoid damaging mosfet ?
