NOTE: Once your NOOK has enough power to turn on, you can see how much power remains in the battery
by checking the battery charge indicator in the right corner of the Status Bar.
NOTE: Some personal computers must be turned on in order to charge other devices through USB ports.
When these computers are asleep or turned off, their USB ports are inactive, and no charging takes
place. If you have connected your NOOK to your personal computer and the NOOK does not seem
to be charging, check your computer's documentation to determine what the requirements are for
charging devices through USB ports.
3. Once your NOOK has fully charged, unplug the USB cable from your NOOK.
To charge your NOOK from a wall outlet with a power adapter, do this:

Resetting Your NOOK
Performing a Soft Reset
If for some reason your NOOK becomes unresponsive, you can perform a soft reset to restart the device.
1. Press and hold the power button for 20 seconds, then release the power button.
2. Press the power button again for 2 seconds to turn on your NOOK.
Low Power
You can see how much power remains in your battery by checking the battery icon in the Status Bar, or by check-
ing the Battery indicator on the Device Info settings screen. (To see the Device Info screen, tap the gear icon in the
Status Bar, tap All Settings, and on the Settings screen tap the Device Info menu choice.)
If you turn on your NOOK when its battery charge is almost depleted, a warning appears on the screen, suggesting
that you begin charging your NOOK before trying to use it.
If the battery is depleted, your NOOK will shut down until it has been sufficiently recharged.
Charging Recommendations
Your NOOK contains a rechargeable battery. To maximize battery life:
• Avoid fully discharging the battery. Charge your NOOK after several hours of use or when you see the low
charge alert, rather than continuing to use it until it turns itself off.
