I've had this DSi for almost a year now [got it last Christmas]. It is a refurbished black one from Game Stop, so there is no warranty.
I don't think I have the money to send it to Nintendo to get it fixed, not to buy a new battery [do they even sell them in Game Stops at the mall? I've never seen any there.]
I've never dropped it, ripped out the charger, etc.; that thing is [or, possibly, was ] my baby.
Most forums I go onto [Yahoo!Answers, Nintendo, etc] just say "lul, I dunno; call Nintendo?", so I am hoping someone on here has better advice.
One bit I got was to give it a few days to take a break; could this help?
Does anyone have any advice on what to do?
Thanks for any and all help.
