the external display is connected when operations are resumed.  In this case, con-
nect the external display or press 
Fn + F3.
zPress 
Fn+F2 and adjust the brightness. 
The power has not been 
turned off, but after a certain 
period of time, there is no 
displayzHas 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-

or there are dots not dis-
playing the correct colorszIf 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.
zHigh-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.

An error occurs or the com-
puter freezes while using 
DualviewzIf you use a 3D screen saver while in Dualview mode at a high resolution, an error 
may occur or the computer may freeze. Under these conditions, do not use a 3D 
screen saver.
When the screensaver is 
set, an error will occur dur-
ing a resume operationzWhen the computer automatically enters the standby or hibernation mode while the 
screensaver is running, an error may occur during a resume operation. In such 
cases, turn off the screensaver or try changing the pattern of the screensaver.
