Mine did the same thing. I have an ipod mini 4gb, but the solution may work for you as well. What I did was I left the backlight on and left it playing full blast until the battery was dead. I had to check on it every now and then to get rid of the text warning and that stupid apple, but eventually the battery died, and then i plugged in it to charge for a full day. I hope you get results similer to mine, good luck!
