Display - BenQ Joybook A53 Series User Manual

I hear noise when connecting an earphone to the Joybook.
Verify the following:
• Connect the earphone to other devices, such as a radio to see if
you can still hear that noise. If the noise persists, the earphone
may be out of order.
• If you can hear the noise only when inserting, it is the result of
high instantaneous current. It is a normal phenomenon.
How can I reduce the wearing of the screen hinge when I lift up
the lid of my Joybook?
Please open/close the lid gently and slowly with both hands.
Apply force evenly on both hands to reduce hinge wearing and
prevent deformation or breaking of hinge due to uneven force.
What should I do if a program in Windows freezes?
If your system freezes, press the <Ctrl> + <Alt> + <Del> keys
simultaneously, click Start Task Manager. Under Windows Task
Manager, click the Applications tab, and then click on the
application that freezes and click End Task.
Why is my Joybook running so hot? Is it normal?
Yes. Because all the hardware is in such cramped quarters, it
tends to get hot. To prevent overheating, do not obstruct the
vent. For example, do not use the Joybook in bed where a
blanket may inadvertently cover the vent and block the airflow.
Why does my Joybook seem to turn off itself after a certain
period of inactivity?
This is the default setting of the Joybook to conserve battery
power. The Joybook is configured to use the power saving
feature. You can go to Control Panel, Mobile PC, and Power
Options to select your preferred power plan.
Should I drain the battery of my Joybook every time before
charging to retain its capacity?
No. Your Joybook comes with an Lithium-ion (Li-ion) battery
pack. This is one of the newest cell types available. It is also the
lightest battery type currently available on a commercial basis
and can provide more power than other main cell types. There
are no known problems of memory effect with this battery type
and it is the easiest battery type to be maintained.
