30 minutos - 2 horas
My ipod would not turn on, instead of taking it to apple and paying an astronomical amount of money I found ifixit. I diagnosed my ipod to have an unworking battery and ordered one from ifixit. In under an hour, following the steps on this site, my ipod was up and running! Thanks Ifixit!
Followed the steps as given and it worked. Most difficult part was opening the ipod.
Make sure your careful when you split the ipod into two halves the wires may break.
