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 storing it for an extended period and when in checked baggage on an
airplane.
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.
When the touchscreen is dimmed, you can still use it. Tap a menu choice or button, that action
will be carried out, and the touchscreen will brighten.
To light up the touchscreen when it is unlit, but your
NOOK is not sleeping, tap the touchscreen,
tap the
NOOK button, or press and release the power button.
