- 

- For 36 hours after pressing the Sleep/Wake button and turning off the screen, iPod nano is in Standby and will quickly wake up when you press the Sleep/Wake button again. 

- After 36 hours in Standby with no activity, iPod nano will shut down automatically. Pressing the Sleep/Wake button after iPod nano is shut down will turn on iPod nano and display the main Home screen.
