ok so i was listening to my ipod and when i was finished i turned it off. when i wanted to listen again i hit the play button but nothing happened. so i figured it was a dead battery and that it needed to be charged. but when i connected it to a charger it wouldnt even charge. i connected it to 3 different computers (1 pc and 2 macs) and still nothing happened. is my ipod officially dead and am i going to have to buy a new one or is there a way to restore this back to life?
