Display screen is blank or
difficult to read.
• 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 27.)
• An external monitor may be selected. Press the Fn and P1 keys to select
the computer display screen. (See page 27.)
• 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.
Cursor is not tracking the pen. Calibrate the pen. See “Calibrating the digitizer” on page 75.
Computer not responding to pen. 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 30.) If the system
responds to a keyboard but not to the pen, contact your local help desk or
reseller for further assistance.
Headphone or speaker volume is
too low.
• The volume may be in Mute mode or set too low. Follow the
instructions in “Adjusting headphone or speaker volume” on page 45.
• Make sure the volume control in your audio software is set to an audible
level.
An external device is not working
with the computer.
The device may need to be enabled in the computer’s configuration program
(BIOS Setup). Contact your local help desk or reseller.
