Power Management
Your notebook offers automatic and modifiable power saving func-
tions that you can use to maximize battery life and reduce overall
operating costs. The power saving modes are known as standby
mode and suspend (hibernate) mode.
Standby Mode
When in standby mode, the contents of the RAM of your notebook
are preserved while practically all other components of your note-
book are shut down, reducing your power consumption to a mini-
mum. By pressing any key on the keypad, you can bring your
notebook back to the fully operational state. You will restart at
precisely the line in which you were working prior to the interrup-
tion. The computer takes less time to go into and come out of
standby mode, but uses more power than suspend (hibernate)
mode.
Suspend (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) are 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 note-
book is closed (assuming the correct ACPI setting), the notebook
saves the data in RAM for you automatically. You will restart at
precisely the line in which you were working prior to the interrup-
tion. The computer uses no power while it is in suspend (hiber-
nate) mode, but it takes a little longer for the computer to go into
and come out of hibernation compared to standby.
