Recommendations and Troubleshooting

The following are descriptions of situations that you may encounter during use of
the Joybook 8100, along with basic troubleshooting steps. If you are not able to
resolve the issue, immediately contact a BenQ service center for assistance.
Joybook 8100 will not start up, even though the power button was pressed.
Check the power indicator.
If it is not lit up, Joybook 8100 is not being supplied by power-either from an
external power source via the AC adapter or from the battery. Make sure that the
AC adapter is correctly inserted into the power jack of Joybook 8100 and a work-
ing electrical socket, and allow the battery to begin charging.
If the power indicator is lit up in blue, the Joybook 8100 is being supplied nor-
mally with power, meaning that the problem lies elsewhere.
If you have added any hardware (for example, memory), check if it has
been installed correctly.
It is possible that certain operating system files are damaged or missing.
If so, you may need to first back up all your data and then use the restore
CD that came with the Joybook 8100 to return the its software to origi-
nal state. Please note however that doing so will cause all of your per-
sonal data on the hard disk drive to be lost!
There is nothing visible on the screen.
Check the power indicator.
If it is not lit up, no power is being supplied to Joybook 8100. Connect the AC
adapter and restart Joybook 8100.
If it is lit up in orange, Joybook 8100 has entered sleep mode in order to conserve
power. Simply pressing the power button should return Joybook 8100 to normal
operating mode.
If it is lit up in blue, Joybook 8100 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 com-
bination 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 8100's
own LCD panel or to use simultaneous display.
There is no sound coming from the speakers.
Check the following:
The speakers may have been muted. Look at the volume control (speaker icon)
on the Windows Taskbar to see if mute has been set. If so, turn off the mute.
The speakers may have been turned off. Use the Fn + F7 hotkey combination to
turn them on.
The volume may have been set too low. Use the Fn + F9 hotkey combination to
increase the volume.
An earphone or external speakers may be connected to the audio-out jack, auto-
matically turning off Joybook 8100's internal speakers.
CD or DVD discs don't seem to be detected by Joybook 8100.
Please verify the following:
Joybook 8100 is turned on.
There are no other discs inserted in the optical drive.
The disk that you want to use is properly inserted in the optical drive.
The CD or DVD discs are in good condition.
DVD movies will not play.
The region code of the DVD inserted must match that of the DVD playback soft-
ware used. This region code can be set up to five times. If you have not reached
this limit, a prompt will appear that will allow you to change the region code of
the software to match that of the move. Otherwise, you can only play back DVDs
with the same region code as the last DVD played back successfully.
Joybook 8100 is unable to use the infrared port to communicate with other
devices.
Please confirm the following:

The infrared port is clean, and there are no objects blocking the path between
Joybook 8100 and the external device.
The distance and angle between Joybook 8100 and device do not exceed the
effective range of the port.
You are not attempting to establish the link under conditions of direct sunlight.
There are no incompatibilities between the communications software that is
attempting to establish the infrared link and any other communications soft-
ware on Joybook 8100. For further information, please consult the manual for
the particular software.
