I was erasing all settings... then it shut off

Hi, I was in the middle of erasing the settings on my 2nd Gen, 3.0 FW iPod touch, when it shut off. I turned it back on and it said the battery was empty and to charge it. Well, I made sure and checked before I started and it was at 3/4ths, so I guess that was wrong. I have it plugged into the wall right now, but I don't think it is charging. I can turn on the iPod, and it'll show the Apple logo, but then it shuts off in about 5 seconds. There's nothing on the screen otherwise. when I plug my ipod into the wall or my computer, it displays the logo, but then shuts off again. What should I do?
