Recommendations and Troubleshooting

The following are descriptions of situations that you may encoun-
ter 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 electrical socket, and
allow the battery to begin charging.
• If the power indicator is lit up in blue, the Joybook is being sup-
plied normally with power, meaning that the problem lies else-
where.
• 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 dam-
aged or missing. If so, you may need to first back up all
your data in the C:\ drive and then refer to "Recovering
Your System" on page 30 to recover your system to its
original state.
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 blinks green, Joybook has entered standby mode in order to
conserve power. Simply pressing the power button should return
Joybook to normal operating mode.
• If it is lit up in green, Joybook is being supplied normally with
power. There are two possible causes for the problem.
32 Recommendations and Troubleshooting
• 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 dis-
play 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.
• The speakers may have been turned off. Use the Fn + F6 hotkey
combination to turn them on.
• The volume may have been set too low. Use the Fn + F8 hotkey
combination to increase the volume.
• An earphone or external speaker may be connected to the Ear-
phone Jack, automatically turning off the computer's internal
speakers.
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 software on the computer. For further
