I'm trying to help my friend's daughter get her DSi working. It was working fine, but recently while she was playing it the screen just "shut off". She thought the charge level was fine though when it did this, so it is kind of puzzling. One time recently, she did charge it again and it worked for about 2 hours and then the screen did the same thing.
Now, it is not working at all, not even after trying to charge it. All I get when I try and power it on is a blue light comes on momentarily (where the power light is).
Just wondering if this sounds like the battery needs replacing or if you think it is some other problem with it. Didn't really want to buy a new battery for it without getting some advice from people who have more experience than me with the DSi.
Thanks in advance!
