Transfering charger chip from one motherboard to another

[ponch]

So my new3ds 2015 only works from the charger. The battery is alright so i assume it must be the charging chip. I have another motherboard which is damaged but the chip should be alright. Can i do that?(i will ask a professional). Also could someone show where the charging chip is on motherboard? Can't find it online

If you can use your 3DS while the charger is plugged in it means that the charger works fine since I don't remember the 3DS charge chip to have a "bypass" to directly power the 3DS without the battery (in fact iirc the 3DS doesn't even boot without a battery even if you charge it). So it most likely seems that your battery doesn't hold charge anymore and the charger isn't at fault

I tested three different batteries(one completely new) with it and nothing worked. If the charging chip is not at fault and the battery is alright then what could it be?

Did you test with known charged battery? It would be really strange for your 3DS to power off if the battery is charged. I don't really see where the problem could be honestly

Yes i charged it separately from the console and i installed the program which tells battery percentage(it says 100%). Charging light is off which means it's fully charged. And still, when i remove the charger it immediately turns off with a popping sound. And it also resets date and time so it's like battery was removed.
