Working with the notebook

Using the power-management features

Battery Power Power
The notebook uses less power when the available power-management features are used. You
will then be able to work longer when using the battery before having to recharge it.
Power efficiency is increased and environmental pollution 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.
We recommend the following settings:
Function
Turn off monitor
Turn off hard disk(s)
Energy saving (S3)
Hibernate mode (S4)
► Select the power management functions in your Control Panel.
► Select the Screen Saver in your Control Panel.
or
► Right-click on the desktop. Switch on the screen saver by clicking Personalization –
Change screen saver.
If you need further information about an option, you can get help with most
settings by pressing
When the notebook is in power-saving mode, the following must be remembered:
During power saving mode, open files are held in the main memory
or in a swap file on the hard disk.
Never turn off your notebook while it is in a power saving mode. If the built-in battery is
nearly flat, close the open files and do not go into power saving mode.
If you do not intend to use your notebook for a long period of time:
► Exit power saving mode if necessary via the mouse or keyboard or by switching on the
notebook.
► Close all opened programs and completely shut down the notebook.
