After having let my iPod run completely out of batteries, I plugged it into the USB adapter on my computer. It displays the expected "please wait, very low battery" message, but when it boots up after this stage it immediately goes back to the "very low battery" message after snapping off. I've tried plugging the iPod in another computer, as well as reinstall iTunes. Does anyone know if there is a quick fix for this? Oh, and I've already tried the reset function.
