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
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 lithium ion 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.
• Avoid high temperatures for charging, use, and storage. For more information, see “Temperature Ranges.”
• Charge the battery half way before storing your NOOK for a week or more.
• If you are not going to use your NOOK for more than 30 days, charge the battery to 40%-50% and then turn off
your NOOK.
Safety and Care
This section explains important information about safety and about caring for your NOOK.
Water
CAUTION:
Your NOOK, cables, and adapters are not waterproof.
To avoid risk of overheating, melting, and burns,
keep the device and all accessories away from water and other liquids.
Do not use the cable if either end of the cable gets wet or is exposed to liquid spray. Allow the
end(s) of the cable to dry thoroughly before trying to use the cable. Do not expose your NOOK
to wet or damp conditions. Avoid exposing the device to liquid or food. If liquid is spilled on the
device, make sure to unplug the charging cable and allow the device to dry thoroughly before
reusing. Do NOT attempt to dry out your NOOK with an external heat source such as a dryer or
microwave oven. Clean the screen of your NOOK with a soft cloth and avoid using liquid cleaners
on the screen.
Electricity
Your NOOK is an electrical device. Follow the same basic safety procedures you would follow with any electrical
device.
When charging your NOOK, use only the custom USB cable and power adapter included with your NOOK.
