• Sleep: To save power, your NOOK sleeps after a period of inactivity. It turns o its touchscreen
and wireless circuitry. While your
NOOK is sleeping it displays a screensaver image on the
reading screen. Configure the sleep timer in Settings. Tap settings > Display > Sleep timer.
Do not rely on sleep mode when you should turn on Airplane mode (for example, on an
airplane).
To wake your
NOOK from sleep, press the power button briefly (for a second or so) and
release it.
When your
NOOK awakens from sleep, you are right where you were when it went to sleep.
For normal use, because the reading screen does not consume power, just let your NOOK
sleep. It takes longer for your
NOOK to turn on from o than it does to wake from sleep.
Also, by letting it sleep instead of turning it o, your NOOK wakes up periodically to
perform tasks like downloading new content.
• USB drive mode: When you plug your
NOOK into a personal computer, it connects to USB.
This puts your
NOOK in USB drive mode. In this mode, you can access files on your NOOK
from your personal computer, but your
NOOK is locked until you disconnect it from USB.
