Recommendations And Troubleshooting - BenQ Joybook 5000 series User Manual

Recommendations and Troubleshooting

The following are descriptions of situations that you may encounter during use of
the Joybook, along with basic troubleshooting steps. If you are not able to resolve
the issue, immediately contact a BenQ service center for assistance.
Joybook will not start up, even though the power button was pressed.
Check the power indicator.
If it is not lit up, Joybook 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 and a working elec-
trical socket, and allow the battery to begin charging.
If the power indicator is lit up in blue, the Joybook is being supplied normally
with power, meaning that the problem lies elsewhere.
If you have added any hardware (memory for example), 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 to return the its software to original
state. Please note however that doing so will cause all of your personal
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. 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 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 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'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.
40 Recommendations and Troubleshooting
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 Volume Up/Down Button to
increase the volume.
An earphone or external speakers may be connected to the audio-out jack, auto-
matically turning off the computer's internal speakers.
CD or DVD does not function.
Please verify the following:
Joybook is turned on, and the CD or DVD discs are properly inserted in the cen-
ter of the disc tray in the optical drive.
The disc tray is closed.
The CD or DVD is not bent or badly scratched.
Noise from the optical drive when the disk plays shows that the optical drive may
be deformed, and the computer needs to be repaired. If the disk tray does not
open after the Eject button is pressed, insert a pin into the Emergency Eject hole
to force the tray out.
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 is unable to use the infrared port to communicate with other devices.
Please confirm the following:
Communication speeds for Joybook and the external device are identical.
The infrared port is clean, and there are no objects blocking the path between
Joybook and the external device.
The distance and angle between Joybook 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 the computer. For further information, please consult the manual for
the particular software.
