the power saving function of IDE, and a number of other parameters can be modified.
The actions to execute when the computer is disconnected from or connected to the AC
power supply are defined in /etc/sysconfig/powersave/events. Select the
schemes to use in /etc/sysconfig/powersave/common:
AC_SCHEME="performance"
BATTERY_SCHEME="powersave"
The schemes are stored in files in /etc/sysconfig/powersave. The filenames
are in the format scheme_name-of-the-scheme. The example refers to two
schemes: scheme_performance and scheme_powersave. performance,
powersave, presentation, and acoustic are preconfigured. Existing schemes
can be edited, created, deleted, or associated with different power supply states with
the help of the YaST power management module described in
Power Management Module"

If you use ACPI, you can control the response of your system to ACPI buttons (power,
sleep, lid open, and lid closed). Configure execution of the actions in /etc/
sysconfig/powersave/events. Refer to this configuration file for an explanation
of the individual options.

spective window manager (KDE, GNOME, fvwm, etc.).
EVENT_BUTTON_SLEEP="suspend_to_disk"
When the sleep button is pressed, the system is set to the suspend-to-disk mode.
EVENT_BUTTON_LID_OPEN="ignore"
Nothing happens when the lid is opened.
EVENT_BUTTON_LID_CLOSED="screen_saver"
When the lid is closed, the screen saver is activated.
EVENT_OTHER="ignore"
This event happens if an unknown event is encountered by the daemon. Unknown
events include ACPI hotkeys on some machines.
