I love this handheld, but my 3000 stopped charging a couple years back. I'm pretty sure it's a bad connector in the body itself, since I used to be able to get it to charge if I set the adapter just right.

But this thing is so small and has so many moving parts that I'm a little more wary about taking it apart and swapping out a component than I would be a full-sized console (or even a Game Boy or something). I might just take it to get repaired instead...
