Acok(pin5) seems bit low.Should be 3.3V. Check acok voltage divide resistors.
PR8812
PR8816
PC8818
All three are healthy, but they were all changed to be sure.
The voltage goes up from 2.6-2.7 little by little and remains stable at 3.017. This procedure takes about 10-15 seconds from 2.7 to 3.017
Try Replacing R2 in the ac det voltage divider,even if the value is correct.If that don't help, try lowering the value of R2 resistor a bit(say 5% less value).But don't try value which is way below specified, only 5% difference,not more than that.
I try with another resistor 22k and now ACDET voltage now :2.835 V
============================
I try to out a PQ8803 but charger light is now on
for autoswitching motherboard i put 3V battery betwen +3VA_RTC and GND and autoswitch resolve it.
Now inside Windows, there is a cross on the battery and it says:
plug in 100% fully charged
While the battery is not connected and the MOSFET PQ8803 is out of the board
Hello
I could not find the problem of the charging light turning on.
I assembled the laptop and installed the battery on the device. After 4 or 5 hours, I saw that the device started charging. Later, I took out the charger, after 40 minutes it was empty, I connected the charger again and after an hour it was 100%. Only when the battery was being charged, it went up by 2% and 2%, and the same way while emptying the battery, it was empty by 2% and 2%.
The device has been working for 3 days without any problems.
I no longer care about the charging light of the device, it turns on when there is no battery.
In newer Asus laptops, charging light is on even when there is no battery connected, and they auto start when the battery is unplugged and charger plugged. Your only problem was the burned mosfet and very discharged semifunctional battery.
I don't provide help for people using CH341A and a clip.

Thankful
But why, when the battery was not connected, in Windows, the status of the battery was shown as charging and 100% ؟؟

Asus is a master for screw ups with their buggy firmware and way of operating, although it can be some problem on the board, but the chances are very small. Seen this stupidity many times, it's freaking confusing until one get tens of machines and realize that this is normal behavior.

A bad battery can also be the cause,since you wrote that the battery is faulty.
Get another battery to test and confirm and if it still shows 100%, check the data and clk line.
Note that the voltage might be ok and the resistor impedance fine but it's a signal ,you need an oscilloscope to check the data and clock line and it must have a 9 duty circle.
Thank you, but my main question is, why does the charging light turn on when the battery is not connected to the device, and in Windows it shows the battery status at 100%, while the system works for 4-5 days without any problems.
Anyway, thank you very much dear ones
