There is nothing visible on the screen.
Check the power indicator.
•
If it is not lit up, no power is being supplied to Joybook. Connect the AC
adapter and restart Joybook.
•
If it is lit up in amber, Joybook has entered sleep mode in order to
conserve power. Simply pressing the Power button or any key should
return Joybook to normal operating mode.
•
If it is lit up in blue, Joybook is being supplied normally with power.
There are two possible causes for the problem.
•
The screen's brightness may be set too low. Use the <Fn> +
<F5> hotkey combination to increase the brightness.
The display mode may be set to use an external display. Use the
•
<Fn> + <F3> hotkey combination to switch the display mode to
use Joybook's own LCD panel or to use simultaneous display.
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 Out socket and
the 15-pin mini D-sub video socket on the Joybook. If yes, disconnect
the device connected to the S-Video Out socket on the Joybook to
enable normal signal output from the 15-pin mini D-sub video socket.
In general, if you have connected devices to both the S-Video Out socket
and the 15-pin mini D-sub video socket on the Joybook, the S-Video
Out socket 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?
