Dealing with Problems (Advanced)
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 external display no longer
displays properly
During simultaneous display, the
screen of the external display
becomes disordered
When an MPEG file is being played
with Media Player, the display
destination cannot be switched using
Fn+F3
Setup Utility
[Enter Password] is displayed
[Advanced] and [Boot] menu can not
be registered
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.
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.
Try changing the display by pressing Fn+F3.
If you continue to experience problems, try changing the display destination in
the following menu.
Windows XP
[Start] - [Control Panel] - [Other Control Panel Options] - [Intel(R) Extreme
Graphics] - [Devices]
Windows 2000
[Start] - [Settings] - [Control Panel] - [Intel(R) Extreme Graphics] - [Devices]
The display destination cannot be switched while an MPEG file is playing. Stop
playing the MPEG file before switching the display destination.
Enter the Supervisor Password or User Password. If you have forgotten it,
contact Panasonic Technical Support.
Restart the Setup Utility with the Supervisor Password.
