Power Management
Your notebook offers automatic and modifiable power saving functions that you can use
to maximise battery life and reduce overall operating costs. The power saving modes are
known as sleep mode and hibernate mode.
Sleep Mode
When in sleep mode, the contents of the RAM of your notebook are preserved while
practically all other components of your notebook are shut down, reducing your power
consumption to a minimum. By pressing any key on the keypad, you can bring your
notebook back to the fully operational state. You will restart in precisely the same state in
which you were working prior to the interruption. The computer takes less time to go into
and come out of sleep mode, but uses more power than hibernate mode.
Hibernate Mode
The hibernate mode is an alternative to a complete shutdown of the notebook. In this
mode all data from RAM (system and graphic data) is copied to the hard disk as a file. As
soon as the data has been safely saved, the notebook powers down. When the notebook is
switched on again, this file is written back to RAM by the BIOS. In a few moments the
notebook is in the exact state as when it was last used. If while working on a document the
notebook is closed (assuming the correct ACPI setting), the notebook saves the data in
RAM for you automatically. You will restart in precisely the same state in which you were
working prior to the interruption. The computer uses no power while it is in hibernate
mode, but it takes a little longer for the computer to go into and come out of hibernation
compared to sleep mode.
