Lithium ion Battery
Your Your Fujitsu Stylistic Q335 has a Lithium ion
battery that provides power for operating your
Tablet PC when no external power source is
available. The battery is durable and long lasting,
but should not be exposed to extreme tempera-
tures, high voltages, chemicals or other hazards.
The Lithium ion battery operating time may
become shorter if it is used under the following
conditions:
When used at temperatures that exceeds a
•
low of 41°F (5°C) or a high of 95°F (35°C).
Extreme temperatures not only reduce
charging efficiency, but can also cause battery
deterioration. The Charging icon on the Status
Indicator panel will flash when you try to
charge a battery that is outside its operating
temperature range.
When using a high current device such as a
•
modem, CD-ROM drive or the hard drive,
using the AC adapter will conserve your battery
life.
Do not leave a faulty battery in your Tablet
PC. It may damage your AC adapter, another
battery or your Tablet PC itself. It may also
prevent operation of your Tablet PC by
draining all available current into the bad
battery.
Actual battery life will vary based on screen
brightness, applications, features, power
management settings, battery condition and
other customer preferences. CD-ROM drive
or hard drive usage may also have a
significantly impact on battery life. The
battery ages. If your battery is running low
quickly, you should replace it with a new one.

Recharging the Batteries
If you want to know the condition of the primary
Lithium ion battery, check the Battery Level
indicator located on the Status Indicator panel. The
indicator changes as the battery level changes.
The Lithium ion battery is recharged internally
using the AC adapter. To recharge the battery
make sure the battery that needs to be charged
is installed in your Tablet PC and connect the
AC adapter.
Make sure that the Battery Charging
indicator and the percentage charge is
shown inside the Battery Level icon on the
Status Indicator Panel.
There is no memory effect on the Lithium ion
battery therefore you do not need to discharge
the battery completely before recharging. The
charge times will be significantly longer if your
Tablet PC is in use while the battery is charging.
If you want to charge the battery more quickly, put
your Tablet PC into Standby mode, or turn it off
while the adapter is charging the battery.
Using heavy current devices such as Modem
or frequent CD-ROM and PCMCIA powered
external devices accesses may prevent
charging completely.
