Display - BenQ Joybook R42 Series User Manual

Yes. Because all the hardware is in such cramped quarters, it tends to get
hot. You should avoid using your Joybook on blankets, bed, or other
materials that keeps the heat in.
Why does my Joybook seem to turn off itself after a certain period of
inactivity?
This is the default setting of 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 in Windows to adjust the
setting manually.
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 care for.
