Working with the notebook
Using the energy saving functions
EnergyEnergyBattery
The notebook uses less power when the available en ergy-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 pow er options, you can make significant savings and
at the same time help protect the environment.
When you fold d own and close the LCD screen, depending on th e s etting in Windows,
the notebook automatically enters a power saving m ode.
► Set the energy saving functions in y our Control P anel.
If you need further information about an option, you can get help with most
settings by pressing
F1
to open the Microsoft Help.
When the notebook i
s in energy saving mode, the fo llow ing must be remembered:
During energy sa vi
ng mode, open data is h eld in main m emory 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, cl
ose 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 noteb ook.
► Close all opened programs and completely shut down the notebook.
