I have 4 working DSi XL consoles. On 3 of them I experience the same difficulty charging the battery. When the charger is plugged, its terminal makes EITHER poor contact OR none at all, and I have to twist and turn and contort the charger terminal to get the charging light to come on and to stay on. I’ve opened one of the consoles (the “hardest to charge” one) to replace the port with spares bought off the Internet But the soldered leads on the port seem fine. However it looks as though there is a design problem which makes it difficult to access the component to check it properly. I’d just as soon remove the one port and replace it as a matter of course - as a learning experience - but i thought I’d ask HERE first. More experienced do-it-yourselfers: can you help? Advice, please (photos will be GREAT.
I’m not an expert, but I can say you that with my laptop I had the same problem, the DC jack was broken (I couldn’t see the damage from outside) and I repaired it changing the jack. I don’t know which problem you have, but maybe it is the same. ;) however check the power supply to be sure that the problem is in the consoles. Hope this will help. G.
If replacing the charge did not help the charging issue, then I would use a multimeter and check I have conductivity from the the port to the EMI square located to the left of the port. I sometimes find that the fuse (F1) is blown or that the EMI square is cracked, loose, or broken
