Dealing with Problems

 

(Summary)

No display after powering on

The  power  has  not  been
turned off, but after a cer-
tain period of time, there is
no display

The cursor cannot be con-
trolled

An afterimage appears (e.g.,
green,  red,  and  blue  dots
remain on the display) or
there are dots not display-
ing the correct colors.

The  external  display  no
longer displays properly

The screen becomes disor-
dered

Resolution or the number of
colors of the display changes

During  simultaneous  dis-
play*, the screen of the ex-
ternal display becomes dis-
ordered

When setting the screensaver,
an error may occur during a
resume operation

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 by using
the standby or hibernation function, there may be no display on the LCD unless the
external display is connected when operations are resumed.  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 the standby or hiberna-
tion mode.  (

 

 “Computing On the Road”)  Press the power switch.

Did you repeatedly and continuously press 

  

Fn 

  +   

F3

   ?

Before holding down 

  

Fn

   +   

F3

   continuously, make sure the active display has been

completely switched.

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.

After the display destination of the screen is switched with 

  

Fn 

  +   

F3

   , the resolution or

number of colors of the display may change. Set the display again.

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.

 Display

* To display the same screen on both the internal LCD and external display:
