My mp3 won't turn on

Could be something simple, like a bad cable.

Try spell check, it will make a difference.

Slide the power switch up all the way and hold it there for fifteen seconds or so. This will reset the player.
If this doesn't, please reply to this post and we can go from there.

you've got a messed up memory on your battery. try it in the frezzer, then if that doesn't work, then get a replacement battery.

Have you tried charching or changing the battery? If not please do so. If that does not work clean the terminals where the battery is.

THE INTERNAL BATTERY NEEDS TO BE REPLACED OR THERE IS A BROKEN WIRE

It doesn;t matter if it turns on or not - it only matters if the computer recognizes that something has been plugged in, try one more time:
Try this: disconnect the player from the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard.

If your iPod nano won’t turn on or respond
1) Make sure the Hold switch is off.

2) If that doesn’t work, connect iPod nano to your computer’s USB or FireWire port. Your
iPod nano battery might need to be recharged.

3) If that doesn’t work, your iPod nano might need to be reset.

a) Toggle the Hold switch on and off (set it to Hold, and then turn it off again).
b)Press and hold the Center and Menu buttons for at least 6 seconds, until the Apple logo appears.

4) If that doesn’t work, you might need to restore iPod nano software.

usually it takes about 6hrs for it to fully charge, if it still does not work after this, check to see if it is in lock mode. hope this helps :)
