Dealing with Problems (Advanced)
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 will 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. Press 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 functioning 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 pur-
poses). 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.
Windows XP
When using DualView, use the same display colors for the external display as those
used by the LCD.
Under the condition that the [Command Prompt] screen is set to “Full Screen”, the
display destination returns to both the internal LCD and external display if “EXIT” is
input and the [Command Prompt] screen is closed, or “Full Screen” is canceled (e.g.,
Alt + Enter ), when the display destination of the screen is switched with
Fn + F3 .
Press Fn + F3 again.
