When there is no display to an external display,

The display destination may be set to the external display.

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
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,
slide 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 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 display may not function correctly when the computer enters the power
saving mode. In such cases, turn off the power to the external display.
Change the size of the icons, etc. using “Icon Enlarger” ( “Icon Enlarger”).
