Panasonic CF-18 Dealing with Problems (Summary)

Troublesahooting

No display after powering on

The power has not been

turned off, but after a cer-

tain 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 display-

ing the correct colors

The external display no

longer displays properly

When you want to display

the fonts or icons at a larger

size

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.

The display destination may be set to the external display.

Try changing the display destination by pressing Fn + F3 .

If you want to switch the display destination repeatedly by pressing Fn + F3 , make

sure that the display destination has switched completely each time before pressing

Fn + F3 again.

Press Fn + F2 and adjust the brightness.

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 function-

ing properly), no defect is considered to exist.

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” ( “Icon Enlarger”).
