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.
The display destination may be set to the external display.
Try changing the display by pressing Fn + F3.
If you want to switch the display destination repeatedly by pressing Fn + F3, make
sure that the display destination has switched completely each time before pressing
Fn + F3 again.
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, con-
nect the external display or press Fn + F3.
Press Fn+F2 and adjust the brightness.
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 trigger-
ing of a selection, like Ctrl.
To save power, your computer may have automatically entered the standby mode
(power indicator blinks green) or hibernation mode (power indicator turns off). In
such cases, press the power switch.
Press Fn + F2 and adjust the brightness. Note, however, that when the brightness
is increased, the battery running time will become shorter.
Brightness can be set to separate levels for when the AC adaptor is connected and
when it is disconnected.
If you are using an external mouse, ensure that the external mouse has been con-
nected correctly.
Restart the computer by using the keyboard (Press
R).
If the computer does not respond to keyboard commands, read "No response"
( page 29).
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 ele-
ments either fail to light or remain constantly lit (that is, more than 99.998% of ele-
ments are functioning properly), no defect is considered to exist.
Changing the number of colors of the display may affect the screen. Restart the
computer.
When using Dualview, use the same display colors for the external display as those
used by the LCD.
When using Dualview, do not press Fn + F3.
Restart your computer immediately after enabling or disabling Dualview.
When an external display not compatible with the power saving mode is used with
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.
