Charging
Indicator Light
If the charge in your NOOK’s battery is very low, it can take up to about 15 minutes before
the charging indicator light turns on. If it does not turn on after half an hour, make sure the
USB cable is firmly seated.
• With a plus sign in the battery charge icon in the status bar (shown above)
It can take up to about 15 seconds before the battery charge icon in the status bar is

Charging your NOOK
Charge your NOOK using:
• A power adapter. Use the supplied power adapter connected to your NOOK through the
supplied USB cable.
• A USB cable (the supplied one or a dierent one)
Wall charging is faster than USB charging. Approximate charging times from fully discharged to fully
charged are:
• Wall charging: 3.5 hours
• USB charging: 6 hours
A fully discharged NOOK will turn on after charging for about 15 minutes or less in most cases, but
the charge is still low. When your NOOK does turn on, it will charge most quickly if you do not use
it while it charges. However, you can use it if you keep it plugged in and charging while you do. If
the battery charge is very low, it can take an hour before your NOOK turns on.
Your NOOK must be on or sleeping to charge. When your NOOK is o and you plug it in
to charge it, your NOOK turns on. Do not turn it o again; it needs to be on to charge. If
you are not using your NOOK, it will sleep and continue to charge.
