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 process- ing 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).

What is Centrino technology? What are the advantages of notebook PC's using the Centrino technology?

The Centrino technology enhances the performance of notebook PC's at low power consumption by optimizing the integrated design of the entire computing system and the application environment. The major components of Centrino technology include Pentium-M CPU, Intel 915 chipset and Intel Pro/Wireless 2100 Mini-PCI network interface card. Therefore, if a notebook PC does not use all of these components, we cannot say it uses the Centrino technology.

Battery and Power

How long should I charge the battery for the first time?

For new Joybooks, you should charge the battery for a minimum of 8 to 12 hours.

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 be the run time of a battery?

Run time will vary on individual Joybooks, based on the application programs being used (i.e. high graphics, games), the number of times data is saved or retrieved from the hard drive and/or optical drive, the memory of notebook, and chemistry and capacity of the battery. A “realistic” average run-time for a battery is 1.5 to 3 hours. Again run time will vary on applications being used and individ- ual notebooks.

What should I do with the battery if I will not use my Joybook for a longtime?

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 bat- tery 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 indi- cator 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.
