I was playing a game on my ds lite and then it suddenly turned off. It wouldn't turn back on so i put the charger in and the orange light appeared but when i pressed the on button it still didn't work. So i leave it in the charger for 30 minutes and take it out. Still doesn't turn on. I put the charger back in and the orange light stays lit for a few seconds and turns off. I unscrewed the back of the battery thing and looked at it and it was fine.

Someone help me restore power to my ds? the light was green when it suddenly turned off.
