Acer Nitro5 (N20C2) doesn't charghe battery

[mon2]

When you attach the battery and power adapter for charging, what is the voltage to ground on PLB2 inductor (either side is ok to measure)?

What is the voltage to ground of ACDET (pin 6) on PUB1?

Try putting a jumper between GND and pin5 of battery connector and then test again.

hi I'm back! Followed your instructions, with battey plugged in and power adapter connected (orange LED on) I have:

> 15,7V on PLB2
> 2,6 V ACDET (pin6 of PUB1

If I put pin5 on GND and next I plug battery and power adapter orange charching LED stay off and same results with power adapter connected or disconnected:on PJP201 battery connector:

0V (GND) on pins 1 - 2 - 5

3,2V on pins 3 - 4

0V on pin 6

15,7V on pins 7 - 8

Acer's have a battery switch and needs to be pressed for charging to start. have you checked that?

I dont' see any switch on the board, anyway sounds strange that as you say charcge must to be started pressiing this switch because if charging isnt' working how come that the orange charging LED is on when power adapter is connected?

SW3 near edp connector. press this switch and check if charging starts.

Get it, there isn't a phisical button so I shorted it with solder, but nothing. I also tried before to close SW3 shorting BI GATE to ground and next plug battery and insert power adapter. The only thing that happen is that ORANGE LED power on but on battery connector there is just 15,8V with battery and 5V without it.
Anyway for sure SW3 start the cherge circuit becauuse while I was making test happened that orange LED didn't light ON and shorting SW3 make it light on, but currente move just 300mA
