ipod shuffle 2nd generation, does not show up in window when plugged into itunes. Also, does not charge(no light comes on).

I have a ipod shuffle (2nd generation) that won't light up when plugged in to the power adapter. I have only used it a few times since I purchased it years ago. Also, when I plug it into my computer with itunes running, it isn't recognized at all, as in nothing happens when I plug the usb cable with ipod attached and on to it. Any help would be much appreciated.
