The steps to reboot or restart your iPod are different depending on the model.
+
+
For the original iPod, iPod (2nd Gen), and iPod (3rd Gen) plug the iPod into the power adapter and plug the power adapter into an electrical outlet (or plug the iPod into a computer), and reset it by depressing the "menu" and "play/pause" simultaneously and continue to hold both buttons until the Apple logo appears.

For all models with a "Clickwheel" -- starting with the iPod (4th Gen) and provided by all subsequent models with the exception of the iPod shuffle and iPod touch lines and the iPod nano (6th Gen) -- plug the iPod to the power adapter and plug the power adapter into an electrical outlet (or plug the iPod into a computer), and reset it by depressing the "menu" and "select" (the center button) until the Apple logo appears. For additional details on resetting the iPod, please refer to "Resetting iPod" from the Apple Support Site.
