Power and Charging
17
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.
Power Management
Your
NOOK
uses quite modest amounts of power compared to a laptop computer. It uses a small
amount of power to turn a page on the reading screen, but no power to keep the page displayed.
The touchscreen does use power when it is lit.
To allow you to manage power use, and to give you the experience that suits your reading habits,
you can configure two inactivity periods:
•
Touchscreen timer
: Time from last touchscreen activity until the touchscreen backlight
is turned off. You can choose among 10, 30 (the default), and 60 seconds. The touchscreen
backlight is dimmed by 50% after half of this time period (5, 15, or 30 seconds).
•
Sleep timer
: Time from last activity (touchscreen or button presses) until your
NOOK
sleeps.
During sleep, a screensaver image is displayed on the reading screen and the touchscreen is unlit.
You can choose among 2, 5 (the default), 10, 15, and 20 minutes.
Low Charge Alerts
Your
NOOK
has two low-charge alerts:
Low charge alert
:
When the battery charge is rather low (about 15% charge), your
NOOK
displays a message to
charge it. You can dismiss the message and continue using your
NOOK
, but you should charge it as
soon as possible. To extend the time that the charge lasts, you can turn Airplane mode on, which
disables all wireless connectivity. If you turn Airplane mode on, you cannot access your online digital
library, The Daily, the Shop, or browse the web.
After your
NOOK
displays the low charge alert, it might turn off wireless connectivity.
When it does, you will not be able to access the your online digital library, The Daily, the
Shop, or browse the web until you charge your
NOOK
.
Critically low charge alert
:
When the battery charge is critically low (too low for continued operation), your
NOOK
displays a
message to charge it and shuts down. The critically low battery level is about 5%.
You must charge your
NOOK
before using it. It will charge faster using the power adapter. When
your
NOOK
has enough charge to run, it will start, but remember that it still has very little charge.
You can use it, but should continue charging it.
