I have an old 4th generation iPod. I know people here might not know what that is lol, but I was using it as an external storage device, and had a few things on there I would like to have. Well, I'm having a problem with the iPod. It won't turn on. If I plug it into an outlet, it works fine and says its charging, but it never gets to "charged", just charging. As soon as you unplug the iPod, it turns off and won't work. If I plug it into my computer, the battery logo comes up and thats it, it won't work. Does anyone know what I can do to fix this?
