Possible cause and solution
• Confirm that the computer is on (the Power icon is displayed
continuously in the Status area).
• The brightness may be set too low, causing the screen to appear too
dark. To change system brightness, press the Fn and Start keys to
open the Xplore menu and adjust the brightness. (See page 28.)
• An external monitor may be selected. Press the Fn and P1 keys to
select the computer display screen. (See page 28.)
• The video time-out may have expired. Tap the display screen to
reactivate the display.
Note: This is a normal, power-saving feature.
• If the Status light is blinking red, the computer is in Sleep mode
because the temperature is below -20° C or above 60° C. When the
temperature returns to a safe operating range, the display screen
automatically comes back on. If possible, move the computer to a
warmer or cooler location.
• If the Status light is continually yellow, the computer is in Sleep or
Hibernate mode. Press the Power On/Off key to resume.
Calibrate the pen. See "Calibrating the digitizer" on page 77.
Connect an external USB keyboard to the computer. If the computer
does not respond to the external keyboard, the application or
operating system may have been corrupted. Press the Reset key.
(See page 33.) If the system responds to a keyboard but not to the
pen, contact your local help desk or reseller for further assistance.
• The volume may be in Mute mode or set too low. Follow the
instructions in "Adjusting headphone or speaker volume" on
page 48.
• Make sure the volume control in your audio software is set to an
audible level.
The device may need to be enabled in the computer's configuration
program (BIOS Setup). Contact your local help desk or reseller.
