Dealing with Problems (Summary)

When there is no display to an external display,

• Check your cable connection to the external display.
• Confirm your display is powered on.
• Check the settings for your external display.

Try changing the display by pressing    

Fn

 

  +   

F3

   .

When displaying only through an external display, if the computer is shut down (includ-
ing the standby or hibernation function), there will be no display on the LCD unless the
external display is connected when the computer is powered on or operations are re-
sumed.  In this case, connect the external display or press    

Fn

 

  +   

F3

   .

Has the computer been set to the power-saving mode?
To resume operation of your computer from the condition the power of the display is off
(for energy conservation purposes), press any key unrelated to the direct triggering of a
selection, like    

Shift

   .

To save power, your computer may have automatically entered either the standby or
hibernation mode.  (

 

 “Computing on the Road”) Rotate the power switch.

Restart the computer by using the keyboard (e.g.,   

   ).

If an image is displayed for a prolonged period of time, an afterimage may appear.  This
is not a malfunction.  The afterimage will disappear when a different screen is displayed.
High-precision and advanced technologies are necessary in the production of color liquid
crystal displays (color LCDs).  Therefore, if 0.002% or less of the picture elements either
fail to light or remain constantly lit (that is, more than 99.998% of elements are function-
ing properly), no defect is considered to exist.

When an external display not compatible with the power saving mode is used with the
computer, the external display may no longer display properly when the computer enters the
condition the power of the display is off (for energy conservation purposes).  In such cases,
turn off the power to the external display.

Changing the number of colors of the display may affect the screen. Restart the computer.

Try changing the display by pressing    

Fn

    +   

F3

   .

If you continue to experience problems, try changing the display in the following menu.

Windows 2000

: [Start] - [Settings] - [Control Panel] - [Intel

®

 Graphics Technology].

Windows XP

: [Start] -[Control Panel] - [Appearance and Themes] - [Display] - [Set-

tings] - [Advanced] - [Intel

®

 Graphics Technology].

When the computer enters the standby or hibernation mode while the screensaver is run-
ning, an error may occur during a resume operation.  In such cases, turn off the screensaver
or try changing the pattern of the screensaver.

If the resolution is set to less than the resolution of the internal LCD and the screen is set to
simultaneous display, the screen will not fill up the entire display.  Also, if the screen is set
to Extended Desktop, the screen may not fill up the entire display.
