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 pur poses), 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.,
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 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.
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
