Flip the iPod Nano's "Hold" switch to "OFF."

The iPod Nano cannot be turn on if the switch is set to "ON."

Reset the iPod Nano. Move the "Hold" switch to "ON" and then "OFF."

Then, press down the "Select" and "Menu" buttons on the Nano. Hold those buttons for about eight seconds.

The Apple logo will then become visible on the iPod Nano. Once this occurs, try turning the iPod Nano on once again.

Connect the iPod Nano to an iPod charger or a computer that is turned on via the iPod Nano's USB cord. Charge the Nano for at least 30 minutes.

Then, try to turn the Nano on.

Update the iPod Nano's software.

Connect the Nano to your computer via the player's USB cable. Open iTunes, and click the iPod Nano's name on the left part of iTunes.

Click the "Summary" option at the top of iTunes. Then, click on the "Check for Updates" button that's positioned in the middle of iTunes.

Follow the instructions that appear inside iTunes in order to install the updates on the Nano.

hope this helps

Connect it to a computer with itunes installed on it. When you connect it it will ask you if you want to sync it with that itunes library. Click yes and if you have no music or videos in the library it will clear the nano. If you have songs or videos in the library it will replace whatever was on the nano with whatever is in the library.

Reset, Retry, Restart, Reinstall, Restore Remember these five basic suggestions if you have a problem with your iPod nano. If one of the following doesn’t help, read on for solutions to specific problems. â Reset your iPod nano. See “General Suggestions,” below. â Retry with a different USB port if you cannot see iPod nano in iTunes. â Restart your computer and make sure you have the latest software updates installed. â Reinstall iPod and iTunes software from the latest versions on the web. â Restore your iPod nano. See “Updating and Restoring iPod Software” on page 50.

There is only one way - and it will erase all your songs:

If you lock your iPod nano screen and can’t unlock it
Normally, if you can connect your iPod nano to the computer it is authorized to work
with, your iPod nano automatically unlocks. If the computer authorized to work with
your iPod nano is unavailable, you can connect iPod nano to another computer and
use iPod Updater to restore your iPod software. See the next section for more
information.
If you want to change the screen lock combination and you can’t remember the
current combination, you must restore the iPod software, and then set a new
combination.
Updating and Restoring iPod Software
You can use iPod Updater to update or restore your iPod software. Apple periodically
updates iPod software to improve performance or add features. It is recommended that
you update your iPod nano to use the latest software. You can also restore the software,
which puts iPod nano back in its original state.
â If you choose to update, the software is updated, but your settings and songs are not
affected.
â If you choose to restore, all data is erased from your iPod nano, including songs, files,
contacts, photos, calendar information, and any other data. All iPod nano settings are
restored to their original state.
To update or restore iPod nano with the latest software:
1 Go to www.apple.com/support/ipod and download the latest iPod Update. The update
has the latest software for all models of iPod.
2 Double-click the software installation file and follow the onscreen instructions to install
the iPod update.
3 Connect iPod nano to your computer and open iTunes. The iPod Updater application
opens.
If you’re using a Windows PC and the iPod Updater application doesn’t open
automatically, you can find the updater by choosing Start > All Programs > iPod.
4 Follow the onscreen instructions to update or restore iPod software.
If you use the iPod Updater application and it doesn’t recognize that iPod nano is
connected to your computer, reset iPod nano (see page 45).
If you want to restore iPod software and you don’t have an Internet connection, you
can use the iPod Updater application that was installed on your computer when you
installed the software from the iPod CD.

Remember these five basic suggestions if you have a problem with your iPod nano. If

First I would suggest you make sure the iPod is connected correctly, and that you wait until the iPod has finished updating.
If you are sure of that, you can always restore the iPod to it's original settings.
(I would also suggest that you are using the most updated version of iTunes)
But before you restore your iPod, there are a few steps you can take to try and fix this problem.
If you can’t download a song or other item to iPod nano 
The song might have been encoded in a format that iPod nano doesn’t support. The 
following audio file formats are supported by iPod nano. These include formats for 
audiobooks and podcasting: 
 AAC (M4A, M4B, M4P) (up to 320 Kbps) 
 Apple Lossless (a high-quality compressed format) 
 MP3 (up to 320 Kbps) 
 MP3 Variable Bit Rate (VBR) 
 WAV

The most common is to reset the iPod. To do this:

•  toggle the Hold switch on and off ( Set it to hold then turn it off again) 
  
• Then press and hold the Center and Menu buttons for at least 6 seconds untill the Apple logo appears.
  

If this does not work I would consider restoring. This means you will loose all your music,pictures, videos..ect. But from it sounds, you don't have anything on your iPod to loose.
