iPod won't turn on or charge
I have an iPod 4th generation nano. Yesterday morning my iPod was working, the battery was low so I plugged it into a wall outlet. I noticed that it was still turned on so I turned it off. The charging battery icon came on. About 20 minutes later I was going to listen to it while it was charging. The screen was black, the charging battery sign was off. it would not come on. So I continued to charge it for several hours. I checked it and still nothing. I connected to several usb ports on my computer, and still nothing happened. Normally when I plug the ipod into the computer a box will appear about charging the iPod. But nothing happened. I went to itunes and it didn't recognised the iPod. I tried to reset it several times by turning the hold button off and on and holding the menu and select down for 6 -30 seconds. Will appreciate any help. Thank you.
