At the time of purchase, the display setting is preset for an external display. If you
connect an external display, the screen is displayed on the external display.
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 (except when the computer is
in the Dual-Display Mode).
When displaying only through an external display, if the computer is shut down by
using the suspend* or hibernation function, there will be no display on the LCD

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.
Select [Start] - [Settings] - [Control Panel] - [Mouse] - [Motion] and add the check
