Power and Charging
This section explains your NOOK’s power management and charging.
Device States
Your NOOK is in one of five states:
O:
Your NOOK is o. Nothing is running.
When you first take your NOOK out of the package, it is o. We recommend that you also turn
your NOOK o when in checked baggage on an airplane. After 72 hours of sleep, your NOOK turns
o automatically to conserve battery charge.
To turn your NOOK o, press and hold the power button for about 5 seconds, until the reading
screen is white and the touchscreen is dark. Then release the power button.
Do not turn o your NOOK while it is plugged into a power adapter or USB. If you do, it
will not charge.
On:
Your NOOK is on. When your NOOK is on, everything works. The main and touch screens are both
lit, and you can read content and listen to music or audiobooks. If Airplane mode is on, you cannot
do things that require the radio, such as shopping at the B&N eBookstore.
To turn your NOOK on, press the power button briefly (for a second or so) and release it, connect
your NOOK to a personal computer using the USB cable, or begin charging your NOOK using a wall
outlet.
When your NOOK powers on, it takes you to the Home screen. It also connects to the network
and scans the microSD
TM
card to check for changes in content.
If you are just charging your NOOK and don’t need it to be on, don’t worry. It will go to sleep.
Touchscreen backlight dimmed and then turned o:
To save power, your NOOK automatically dims the touchscreen and then turns it o when the
touchscreen is not being used. Everything else is still on. You can continue turning pages with the
Next Page and Previous Page buttons, or by swiping your finger on the unlit touchscreen. You
can continue listening to music or an audiobook. Configure the touchscreen timer in Settings. Tap
settings > Display > Touchscreen timer.
