Charging Your NOOK
There are two ways to charge your NOOK. You can plug it into your personal computer. Or you can use a power
adapter and plug it into a wall outlet. (If your NOOK does not include a power adapter in box, you can purchase one
from a Barnes & Noble store or online at http://www.barnesandnoble.com.) The diagram below shows the compo-
nents available for charging your NOOK.
CAUTION: If you are using a power adapter, use only a Barnes & Noble power adapter and custom microUSB
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. Use only a NOOK
Simple Touch Reader power adapter and cable.
To charge your NOOK from your personal computer, do this:
1. Insert the large end of the USB cable into a USB port on your personal computer.
2. Plug the NOOK end of the USB cable into your NOOK. If your NOOK was turned o, it will now turn itself on.
NOTE: Depending on how much power remains in the battery, it might take up to 4 hours to fully recharge
your NOOK through a USB port. Do not turn o 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.
NOTE: Some personal computers must be turned on in order to charge other devices through USB ports.
When these computers are asleep or turned o, 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.
