I accidentally droped my ipod nano 4G it truns on

slide the hold switch on and off a couple of times...then press and hold menu and center buttons till an apple logo comes on screen...connect to system and restore with itunes.

Check your battery. I feel the battery has gone. Dead as a dodo, as the saying goes.

do a reset by pushing middle button and menu button

You have to reset your iPod. (Note: This is for the 3rd generation iPod Nano)

To reset iPod nano:
1 Toggle the Hold switch on and off (slide it to HOLD and then back again).
2 Press and hold the Menu and Center buttons for at least 6 seconds, until the Apple logo appears.


If iPod nano won’t turn on or respond

- Make sure the Hold switch isn’t set to HOLD.
- The iPod nano battery might need to be recharged. Connect iPod nano to your computer or to an Apple USB Power Adapter and let the battery recharge. Look for the lightning bolt icon on the iPod nano screen to verify that iPod nano is receiving a charge.

if by the on/off thing do you mean the hold switch?
If you do, make sure it's to the left. If it is to the right it disables the keys. Other than that, to turn on press any button. To turn off hold play for 3-5 seconds.

I think your ipod is dead. This happened to me to. I was listening to it when I arrived at my destination, and I thought I turned it off and I put it in my pocket. Later that day when I went to listen to it, it wouldn't turn on at all. Aparently, it had stayed on. Hold the pause button for five to ten seconds. The apple symbol will appear on your ipod. Immeadility put it in your docking station before it goes away. Your ipod will turn on, and itwill start charging.

I hope this helps. Please rate my solution.

try pressing and holding the center and menu buttons both at once until the apple logo shows up.. thats the normal troubleshooting routine.
