Dsi charging lite but not opening

As in the title, the DSi orange light turn's on, but it's not opening. The screen doesn't flicker, just nothing is happening. I saw it's maybe a battery problem, but I don't know since the battery I have is in pretty good shape I'd say since there isn't any traces of corrosion, and it's not expending. Help would be appreciated. (sorry if there are errors, English isn't my language.)
