Recommendations and Troubleshooting

The following are descriptions of situations that you may encounter during use of the computer, along with basic troubleshooting steps. If you are
not able to resolve the issue, immediately contact a BenQ service center for assistance.
The computer will not start up, even
though the power button was pressed.
Check the power indicator.
• If it is not lit up, the computer 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 the computer and a working electrical socket, and allow the battery
to begin charging.
• If the power indicator is lit up in blue, the computer is being supplied
normally with power, meaning that the problem lies elsewhere.
• If you have added any hardware (for example, memory or a wireless net-
work card), 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 use the restore CD that came with the computer
to return the computer's software to its original state. Please note how-
ever 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 the computer. Connect
the AC adapter and restart the computer.
• If it is lit up in orange, the computer has entered sleep mode in order to
conserve power. Simply pressing the power button should return the
computer to normal operating mode.
26 Recommendations and Troubleshooting
• lf it is lit up in blue, the computer 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 the computer's
own LCD panel or to use simultaneous display.
There is no sound coming from the speak-
ers.
Check the following:
• The speakers may have been muted. Look at the volume control
(speaker icon) in the Windows task bar 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 combi-
nation to turn them on.
• The volume may have been set too low. Use the Fn + F9 hotkey combi-
nation to increase the volume.
• An earphone or external speakers may be connected to the audio-out
jack, automatically turning off the computer's internal speakers.
