Hello Kitt2003bbjb,
I would be concerned too if my iPod nano's was not powering on. I recommend following the steps below:
Will not turn on or screen remains dark
- Connect iPod to power for at least ten minutes to ensure that the battery has enough charge to allow iPod to turn on.
- If iPod does not turn on after ten minutes, try resetting the device while it is still connected to power. Press and hold the Sleep/Wake button and the Home button until the screen goes dark. The Apple logo should appear after a few seconds, then the Home screen should appear.
- If the Apple logo appears on the display, connect iPod to a computer and verify that it appears in iTunes and can play music. If iPod appears in iTunes and can play music, no further troubleshooting is needed.
- If the screen remains dark and will not turn on, then your iPod may need service.
I got this information from the following article for the 6th generation iPod nano. The steps are the same, except I updated the second step with the reset for the 7th generation iPod nano:
