I have a Nintendo 3DS that will charge for a few minutes and then stops. The battery is new (actually i’ve tried 2 different batteries) and I’ve tried 3 different charges that work fine. I have several 3DS systems that all charge fine with these chargers, so I feel I can safely rule out a faulty charger. I have been able to put a charge to the battery by “stack charging” it. (Plug it in, charge, light goes out, unplug, plug back in……repeat, but who wants to do that!) I am not sure what is causing it, and would like to see if any of you have experienced this kind of charging problem. I thought possibly, overheating of the charge circuit? Bad component? (Although I tested the motherboard and did a visual inspection, nothing was found.) It would help if I could find some schematics. Fat chance though, right? So much fun we’re having. Thanks.
Fixed. I replaced the charge port and did a hard reset. Seems to work fine now.
