Why won't my iPod work?
I had replaced the battery cause it was old. Since then the iPod doesn't charge at the computer but turns when plugged into the wall. Message says to connect to a computer to resolve issue. But it won't turn on when plugged into the computer. I had changed the motherboard. Same issue. What else could it be? i swapped everything i could think of that would affect the power and no dice.
the battery to low message sounds to me like a bad hard drive."
As asked by Crisb try a different iPod chord. If that doesn’t work try hooking it to a friend’s pc. If it works then you may have a USB problem. Are you using Mac or windows?
