Hi @petrkoky
Best option is to obtain the schematic for the motherboard and use it to find out what's wrong with the charging circuit.
I cannot find a free download for the schematic online but here's a link to a supplier where you can purchase it for a reasonable price.
There are other websites that have it as well, but this is the cheapest one that I could find. You may have better luck.

@petrkoky you speak of a "repair charger problem" but then go on to say that you need to "repair the power circuit" There is a difference between the charger circuit and the Power circuit. It will help if you can tell us what it is exactly that your computers issues are. The very first thing I would suggest for you to do, is to check the AC adapter for your computer. Make sure it has the right voltage. After that, invest in a USB-C ammeter (it looks like that is what your computer uses as a power connector) and then connect that to your laptop and plug the power supply into the other end of it. Now try to turn your computer on. See how many Amps your computer will pull from the power supply. Let us know what you find out.
Also, if you are unsure what and where to test, post some well focused, large pictures of your motherboard with your Question. That way we can see what you see. Oh yes, before I forget, here is the schematic for the Acer Predator 15 G9 591G P5NCN P7NCN R1.0 motherboard.
Repair is War on Entropy!
