Fujitsu
Rechargeable battery
The built-in battery provides the Tablet PC with the necessary power for use on the move.
You can increase the service life of the battery by caring for the battery properly. The
average battery service life is around 500 charge/discharge cycles.
You can extend the battery service life by taking advantage of the available energy-saving functions.
Charging and maintaining the battery
The Tablet PC battery can only be charged when the ambient temperature is
between 5°C / 41 °F and max. 35°C / 95°F.
You can charge the battery by connecting the Tablet PC to the AC adapter
(see "Connecting the AC adapter", Page 20
).
If the AC adapter is connected when the state of charge of the battery is more than 90%,
charging will not be started. When the state of charge of the battery is less than 90%, the
battery will be charged to 100% as soon as the AC adapter is connected.
If the battery is running low you will hear a warning alarm. If you do not connect the AC adapter
within five minutes of hearing the warning alarm, your Tablet PC will switch off automatically.
Monitoring the battery state of charge
A battery symbol for monitoring the battery capacity is displayed in the system bar /
status indicator. The battery symbol shows you the battery charge.
Using the energy saving functions
The Tablet PC uses less power when the energy saving features are enabled. You will then
be able to work longer when using the battery before having to recharge it.
The energy efficiency is increased and environmental pollution is reduced.
By choosing the best power options, you can make significant savings and
at the same time help protect the environment.
Set the energy saving functions in your Control Panel.
When the Tablet PC is in a power-saving mode, you must remember the following:
During power-saving mode, open data is held in main memory or
in a swap file on the hard disk.
Never switch off the Tablet PC while it is in a power-saving mode. If the built-in battery
is nearly flat, close all open files and do not go into power-saving mode.
If you do not intend to use your Tablet PC for a long period of time:
Exit the power-saving mode if necessary by touching the screen or by switching the Tablet
PC on.
Close all opened programs and completely shut down the Tablet PC.
