FAQ and Troubleshooting

When I connect the Joybook to an external monitor, the display is
abnormal.
The instructions below will guide you through the troubleshooting
process.
•
Use the <Fn> + <F3> function key combination to set external video
signal enabled.
•
Refer to the user's manual of the external monitor to check the settings.
•
Connect the cable to the Joybook and reboot the system. If there is no
display on the external monitor after system reboot, connect Joybook to
a standard VGA monitor and wait until you can see things properly on
that VGA monitor. Then connect the target display to Joybook again.
•
Check if you have connected devices to both the S-Video and VGA
output on the Joybook. If yes, disconnect the device connected to the S-
Video output on the Joybook to enable normal signal output from the
VGA output. In general, if you have connected devices to both S-Video
and VGA output on the Joybook, the S-Video output will be selected in
first priority.
How can I judge if my LCD panel is out of order and what should I do if
it happens?
