Dealing with Problems (Advanced)
Display
The power has not been turned off, but
after a certain period of time, there is
no display
When the battery pack is used, the
screen is darker than when the AC
adaptor is connected
An afterimage appears (e.g., green,
red, and blue dots remain on the
display) or there are dots not
displaying the correct colors
The screen becomes disordered
The external display no longer
displays properly
When you want to display the fonts or
icons at a larger size
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 functioning properly), no defect is considered to exist.
Changing the number of colors and resolution of the display may affect the
screen. Restart the computer.
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" (
You can also change the settings as follows (for more details, refer to the
