Q: i can't shut off my ipod because the power off screen won't slide, how do I fix it?

Try a 'Hard Reset' of your iPod. Hold down the Home Button and Power button simultaenously for 15 seconds. You will see a white Apple logo come up. Your iPod will power back on automatically.

Next, try the following:

- Restore from backup

- Restore to factory settings/new iPod.

If you still have the problem that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order

Never restore from Backup with an issue like this, if it's a software issue it's going to just recreate the issue by putting the same data that's causing the problem back onto the iPod.
