Recommendations and Troubleshooting
The following are descriptions of situations that you may encounter during use of Joybook 5000, along with basic troubleshooting steps. If you are not
able to resolve the issue, immediately contact a BenQ service center for assistance.
Joybook 5000 does not start up, even though the power button was pressed.
Check the power indicator.
•If it doesn't light up, Joybook 5000 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 plugged into the power jack of Joybook 5000 and a working electrical socket to allow the battery to begin charging.
•If the power indicator lights up in blue, Joybook 5000 is being sup- plied normally 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 miss- ing. If so, you may need to use the recovery CDs that came with Joy- book 5000 to return to factory default. However, please note that doing so will cause all of your personal data on the hard disk drive C: to be lost! For how to restore system from the recovery CDs, please refer to"Recovery CD Instructions" on page 33 for details.
There is nothing visible on the screen.
•If it is not lit up, no power is being supplied to Joybook 5000. Connect the AC adapter and restart Joybook 5000.
•If it is lit up in orange, Joybook 5000 has entered sleep mode in order to conserve power. Simply press the power button to return Joybook 5000 to normal operating mode.
•lf it is lit up in blue, Joybook 5000 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 Joybook 5000'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.
•An earphone or external speaker may be connected to the earphone jack, automatically turning off Joybook 5000's internal speakers.
Check the power indicator.
