Wall Charging
To charge your NOOK, use the charging components included with your NOOK.
CAUTION:
Only use the Barnes & Noble power adapter and 30-pin USB cable supplied with your NOOK.
Other power adapters might damage your NOOK and its battery. Do not use a power adapter and
cable intended for other models of NOOK eReader.
NOTE: Using your NOOK’s USB cable, you can connect your NOOK to your personal computer to trans-
fer files. However, connecting your NOOK to your personal computer may not fully charge your
NOOK. To charge your NOOK, you must plug it into a wall outlet.
To charge your NOOK from a wall outlet, do this:
1. Assemble the power adapter and USB cable. Insert the USB end of the cable into the matching receptacle on the
power adapter.
2. Plug the 30-pin end of the USB cable into your NOOK.
3. Plug the power adapter into a compatible electrical outlet. If your NOOK was turned off, it will now turn itself
on.
NOTE: Depending on how much power remains in the battery, it might take around 3-4 hours to fully recharge
your NOOK. Do not turn off your NOOK while it is charging.
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. You may need to drag
your account’s icon to the lock symbol on yourscreen to unlock your NOOK and display the Status Bar,
which runs along the top of the screen.
4. Once your NOOK has fully charged, unplug the power adapter from the electrical outlet. Unplug the USB cable
from your NOOK.
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.
