Mate i have the same problem and guess what i sent it down to melbourne where nintendo repairs is and it was FIXED. If you still have the reciept then u can use the warranty to pay. If not its from $50-the cost of a new ds.

I have a DSi and I love it! There is just TWO problems. No, make that THREE!!!!!!!

1] When I close the darn thing it is supposed to go to battery save mode ( or at least on nitindodogs) and the blue light goes off and i open it and its off!

2]I can be in the middle of beating a hard part of pokemon ranger of the almia region (or any game really) and my hand will bump into it and guess what? It shuts off! I will go and put it on the couch the soft COUCH VEEEERRRY SLLOOWWLLYY and it......... SHUTS OFF! I got this blue DSi at a game stop i think. It has been about 1 or 2 years and now I am TIRED OF IT!!!!!!!

3] How do I get my mom's parental lock off? ;}
