FAQ and troubleshooting 65
Display
There is nothing visible on the screen.
Check the power button.
• If it is not lit up, no power is being supplied to Joybook.
Connect the AC adapter and restart Joybook.
• If it is blinking in white, Joybook has entered sleep mode in
order to conserve power. Pressing the Power button or any key
should return Joybook to normal operating mode.
• If it is lit up in white, 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> + <F9> 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.
How can I judge if my LCD panel is out of order and what
should I do if it happens?
