    Combing through the older threads, I was unable to find a thread that mirrored my exact problem.
    2DS is not charging at all. Battery has been replaced and works in a different 2DS, cable has been checked to be working too.
    It's not a loose charging port. If I charge the battery in a different 3DS I can play just fine, until the charge goes out.
    The thing that baffles me, that's not been described by anyone else, is that the charging light will go on when the cable is plugged in, stay on for a few seconds, and then go off. This can be repeated as many times as I want - for all similar problems there was either no light at all or the light continuously being on but still no charge.
    I'm at a loss on how to even debug this, multimeter is ready though. I've checked F1 and F2 and I get power through both.

    This 2DS means a lot to me for stupid emotional reasons. If there is no way to fix the problem, could the 2DS be modded to take a power supply directly into the battery port or something like that?
    Thank you all for your time :)

    Are you sure there's no bad contact between the 2DS and the charger? Sounds very much like it's something like that... Otherwise it would be a bad contact between the power supply inside the 2DS and the motherboard. Other than that, test the charger on a different 3DS/2DS and see if it has any issues since that's the quickest to test for and solve.

    Spray the charger port with canned air. Remove the battery, press and hold the (POWER) button for 30 seconds to quickly discharge the motherboard, brush the inners of the charger port with a toothbrush dipped in isopropyl rubbing alcohol (70% concentration or higher), and dry it with low heat, low fan speed hairdryer.

    If all else fails, first replace the charger port, then the power supply filter (if the charge LED indicator does't turn on still), and/or lastly the IC charging chip.

    Thank you, both of you. The cable is working on a different DS and I've also tried another cable.

    Reading in another thread, re-connecting the two ribbons inside the 2DS seem to have somewhat bettered the situation. So I did that, plus the cleaning suggested by TPC.

    Now the charging light stays on, but it still feels like charging is not working/extremely slow. According to my multimeter I have connectivity through both fuses and the power supply filter. The IC charging chip is the tiny one with 4 pins on every side, right? I don't have the fine motor skills to replace that one. But I really do appreciate the detailed parts list, great resource for noobs like me.

    I would have no problem with losing the ability to play on-the-go, but it seems the 2DS/3DS are designed in a way that power needs to be drawn from the battery, so only using a cable with no or an empty battery will not even let you turn the console on. Has anyone experience with modding this? I'm always wiling to learn and work myself into topics like these, but I'm so incredibly new to hardware modding that even handling the multimeter has been a learning experience :)

    @rrorg, the most likely culprit for the slow or no charge issue is the IC charging chip if:
    • Battery tested good in another o2DS or o3DS.
    • AC adapter also works on that other 2DS/3DS.
    • Charger port cleaned. Orange LED indicator lets you know o2DS is receiving power.
    • Power supply filter is good because again the orange LED indicator.
    • F1 and F2 microfuses test good if the multimeter detects continuity or change in resistance value.
    That chip can't be removed with a standard soldering iron. It has to be done with a rework station because of the solder underneath the chip.
    See if any of your local electronic repair shops have tools like those.
