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 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), slide any key unrelated to the direct triggering of a
selection, like Shift .
To save power, your computer may have automatically entered the standby or hiberna-
tion mode. ( "Computing On the Road") 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.
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 select-
ing 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 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 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 sav-
ing 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 Fn + F3 .
If you continue to experience problems, try changing the display in the following menu.
