FAQ 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.

General

What is Joybook? What are the differences between Joybooks and
traditional notebooks?
BenQ call it Joybook, because BenQ has combined entertainment and
stylish design with traditional notebook's functions. For example,
enhanced 3D processing power for gaming and movie viewing. With
Joybook, you will be able to enjoy the most exciting audio and visual
experience ever!
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.
What is IEEE 802.11a/b/g?
IEEE 802.11a/b/g is a technical specification issued by the Institute of
Electrical and Electronic Engineers (IEEE) that defines the operation of 5
GHz/54Mbps, 2.4 GHz, 11 Mbps/54Mbps, Direct Sequence Spread
Spectrum Wireless Local Area Networks (WLANs).

Battery and power

How long should I charge the battery for the first time?
The length of the charging time may depend. When the amber light of the
battery indicator goes off, it means that the charging is completed.

My computer won't start up with the battery inserted?
• Make sure the battery is properly inserted.
• Make sure that the battery is fully charged. If this does not work, consult
your BenQ dealer.
What should I do with the battery if I will not use my Joybook for a long
time?
Recharge the battery or discharge it to about 40% full, and then store it in
a dry place at about 15°C to 25°C. Extremely high or low temperature
will shorten the life of battery.
When charging the battery, the power indicator on Joybook suggests that
the battery is fully charged. When I check it from the Power Manager in
Windows, the battery level is only about 95%-99%. Why?
It is the result of the battery protection design of Joybook. When the
power indicator on Joybook is off, it means that the battery has reached a
saturated voltage: 95%-99%. At this moment, the voltage difference
detected by Joybook is very small, so it will reduce the charging current to
prevent overcharging the battery with excess current or voltage, which
will damage the battery. Moreover, in order to protect the battery from
exposing to high voltage and current for a long time during charging, the
battery has been equipped with a protection circuit that will charge the
battery at low current in the final phase.
How come my notebook is not fully charged even after a full night
charge?
Make sure that the Joybook is receiving power. Is the cord plugged in
correctly? When the battery is installed in the computer and it is properly
plugged in to an AC outlet, check to see if the battery level icon is showing
a charge sign. If this does not fix the problem, the battery, the power
source in the notebook, or the AC power cord may be defective. Consult
your BenQ dealer for help and maintenance.
