If you are using WPA or 802.1x security, the computer may need to
reauthenticate before it resumes your application. The Real Time

The Intermec Power Options screen is customizable. You can use
Intermec Settings to determine which options are available to end

action if no option is selected, or to disable the Power Options Screen.
About the Screen Backlight
The computer has an ambient light sensor that automatically adjusts
the brightness of the screen backlight to ensure that the screen is

there is no activity on the computer. To resume activity, press a key or
tap the screen.
You can configure the brightness and the timeout of the screen
backlight.
