*SOLUTION IF WARRANTY EXPIRED!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!*
I tried all of the button combinations listed on this thread, (menu+center, play+center) in numerous different ways, but whenever i unplugged the ipod from the wall, it immediately died again, even tough it said it was charged when it was on the wall. So i called the customer support service for ipods, and since my warranty ran out, they refused to talk to me. They were going to make me pay $30 just to troubleshoot... yeah. pretty helpful service, right? Anyways, since my warranty ran out and my only other option was to buy another ipod for $250, i took LanceYBoY's advice, and it worked! All you have to do is to separate the front of the ipod from the back casing, but be careful because there are ribbons that connect the front to the back. Once you get the ipod opened, look in the back casing, there should be the battery. There are two ribbons, once going from the battery to under the HD, and the other going from the battery to the lower right hand side of the front. All you have to do is unplug the cord that leads to the bottom right and let the ipod sit for 5 or 10 minutes. After that, plug it back up, be careful, because if it breaks, bye bye ipod. after you plug it up, put the ipod back together, which is really easy, just push the two halves together. and plug it up. I plugged mine into my computer, and it was synced it with my music. Once your music has synced, your ipod should be charged, and it should hold the charge! Good luck. Oh, and I am not responsible if your ipod breaks. This method should only be used if your warranty is expired. But don't let it intimidate you, i thought it was going to be a lot harder than it was. It's very simple once you get the ipod opened.
