Power and Charging
This section explains your NOOK’s power management and charging.
Device States
Your NOOK is in one of five states:
Off:
Your NOOK is off. Nothing is running.
When you first take your NOOK out of the package, it is off. We recommend that you also turn your NOOK off when in checked baggage on an airplane. After 72 hours of sleep, your NOOK turns off automatically to conserve battery charge.
To turn your NOOK off, 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 off 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 microSDTM 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 off:
To save power, your NOOK automatically dims the touchscreen and then turns it off 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.
