The screen becomes dis-
ordered

ternal display becomes

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
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
hibernation mode. Slide 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.,
Be sure to use the Display Rotation Tool to rotate the display.
Windows XP
After the display has been rotated, if the Fast User Switching Function is used, or if
the computer enters the standby or hibernation mode and then resumes, the screen
for selecting the user will remain in its rotated position. If you exit Windows in this
condition, then the next time the computer is started up, the screen angle will not
match the operations of the touch pad or the touchscreen. In this case, operations
will return to normal after you have logged onto Windows by using the keyboard.
When the Microsoft IntelliMouse™ Wheel mode or the original mode is set for the
®
touch pad, only scroll operations are possible for the right part or bottom part of the
touch pad. In this case, cursor operations are possible by using the work surface
excluding the right part or bottom part. When no mode is set, the entire surface of the
touch pad can be used for cursor operations.
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 pic-
ture elements either fail to light or remain constantly lit (that is, more than 99.998%
of elements are functioning properly), no defect is considered to exist.
When an external display is used that is incompatible with the power saving modes of
the computer, the display may not function correctly when the computer enters the
power saving mode. In such cases, turn off the power to the external display.
Changing the number of colors and refresh rate 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
If you continue to experience problems, try changing the display in the following menu.
Windows 2000 : [Start] - [Settings] - [Control Panel] - [Intel
Windows XP : [Start] - [Control Panel] - [Other Control Panel Options] - [Intel

set to simultaneous display, the screen will not fill up the entire display.
