Won't turn on without being plugged in
I installed a donor board. When I plug the power in with a battery installed the amber light illuminates. I press power and the blue light comes on and the 3DS boots up. If I remove the power plug when it is booted up it immediately turns off. If I have the battery in and no power cable it will not turn on.
I confirmed the battery is 100% in working order with my other 3DS XL.
