my ipod will not turn on, what should i do
First, make sure it's charged (I'm sure you did!) When this happened to my son's iPod, we held down the sleep and home buttons at the same time for 15 seconds or so until it restarted. After that it behaved normally. Good luck!
this is a common problem with all iPods, most the batteries are now dying due to a recent recalll.
