Typically before trying to reset iPod, try connecting the iPod to a power adapter (with the power adapter into an electrical outlet of course) or connect the iPod to your computer. Make sure the computer is turned on and isn't set to go to sleep. Try resetting the iPod while it is connected to power since this will ensure your ipod battery being dead is not the issue.
Do not reset your iPod if it is connected to your computer and displays any of the following, but instead eject the iPod from with iTunes first:
Turn the Hold switch on and off, ie: slide it to Hold position, then turn it back to non-hold.
Push and hold the "Menu" and "Select" (Center) buttons at the same time until the Apple logo appears (typically about 6 to 8 seconds).
You might need to repeat this step if it does not work the first time.
If you are having trouble rebooting your iPod try seting it on a flat surface and then make sure the finger pressing the Select button is not touching any part of the click wheel. Also make sure that you are pressing the Menu button toward the outside of the click wheel, and not near the center.
Also, double check that your iPod Nano, iPod shuffle, or iPod does not have the Hold switch in the locked position.
