I just baught my ipod from smalldog.com. I read all about it. Came with everything. Great condition. I got it and now I can plug it in and use it but as soon as I unplug it I am not able to use it. It must be pluged in to use it. I have been charging it for like 3 hours or so and I still can't turn it on unless it is pluged in.

Anyone please help me figure out what is wrong
