My iPod Shuffle generation (2nd generation) is not charging turning on!

Well, I had my iPod since 2007. Used till 2008, and was working perfectly. Now it is not working. When I plug it in to the wall using an adapter, it has a quite screaching voice. This is a 2nd gen iPod Shuffle like stated. iTunes NOT recognizing it. Not recognizing USB, in Windows PC anyways. Once it did. Although once I got a message saying "NOT ENOUGH POWER TO CONNECT DEVICE" or something. I think that its because the iPod wasnt used so its batterry so it now doesnt even have enough charge to charge itself I believe. xP. Although any help, would appriciate because I really want to fix this problem! Thanks!
