Using The Energy Saving Functions; Adjusting Fan Control - Fujitsu LIFEBOOK E548 Operating Manual

Working with the notebook

Using the energy saving functions

Battery Energy Energy
The notebook uses less power when the available energy-saving functions are used. 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.
When you fold down and close the LCD screen, depending on the setting in Windows,
the notebook automatically enters a power saving mode.
► Set the energy saving functions in your Control Panel.
If you need further information about an option, you can get help with most
settings by pressing
When the notebook is in energy saving mode, the following must be remembered:
During energy saving mode, open data is held in main memory or
in a swap file on the hard disk.
Never switch the notebook off while it is in an energy saving mode. If the built-in battery
is nearly flat, close all open files and do not go into energy saving mode.
If you do not intend to use your notebook for a long period of time:
► Exit energy saving mode if necessary by moving the mouse, making an entry at the keyboard
or by switching on the notebook.
► Close all opened programs and completely shut down the notebook.

Adjusting fan control

You can adjust the fan control in the BIOS Setup Utility. The following settings are available:
• Normal: The system is cooled to ensure that the maximum system
performance is always available.
• Silent: The fan rotation speed, and therefore the noise created by the fan, is reduced.
► Call up the BIOS Setup Utility.
► In the menu Advanced - Miscellaneous Configurations select the Fan Control function.
► Choose the setting Normal or Silent.
