FAQ and troubleshooting

What should I do if the battery gets hot in my Joybook?
Take the battery out and let it cool down for a while. If the
problem persists when the battery is inserted again into your
Joybook later, the battery could be defective and it may need to
be replaced. Consult your BenQ dealer for help and
maintenance.
I have pressed the Power button, but my Joybook cannot start
up.
Check the Power button indicator.
• If it is not lit up, your Joybook is not being supplied by power,
either from an external power source via the power adapter or
from the battery pack. Make sure you have connected the
power adapter correctly to the power jack of your Joybook and
a working electrical outlet, so the battery can start charging.
• If the Power button indicator lights up in blue, the
Joybook is being supplied normally with power,
meaning that the problem lies elsewhere.
• If you have added or replaced any hardware, 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 back up all
your data first, and then recover your system. Refer to
"Recovering your system using QDataTrove" on page
45
for details.
Why does the battery on my Joybook seem to last shorter and
shorter?
It is normal for Lithium-ion (Li-ion) batteries to decline in
capacity over time.
Connection
What is a Wireless LAN (WLAN)?
A WLAN is a type of Local Area Network (LAN) that uses high
frequency radio waves rather than wires to communicate and
transmit data among nodes. It is a flexible data communication
system implemented as an extension to, or as an alternative for,
a wired LAN within a building or campus.
I cannot connect to the Internet with the built-in network
interface on my Joybook. Why?
Check if the network has a fixed MAC address. Contact your
network administrator for further solutions.
