Standby (ACPI S1, APM standby)
Switches some devices off (manufacturer-dependent).
Make sure that the following default options are set in the file /etc/sysconfig/
powersave/events for the correct processing of suspend, standby, and resume
(default settings following the installation of SUSE Linux Enterprise):
EVENT_GLOBAL_SUSPEND2DISK=
"prepare_suspend_to_disk screen_saver do_suspend_to_disk"
EVENT_GLOBAL_SUSPEND2RAM=
"prepare_suspend_to_ram screen_saver do_suspend_to_ram"
EVENT_GLOBAL_STANDBY=
"prepare_standby screen_saver do_standby"
EVENT_GLOBAL_RESUME_SUSPEND2DISK=
"restore_after_suspend_to_disk"
EVENT_GLOBAL_RESUME_SUSPEND2RAM=
"restore_after_suspend_to_ram"
EVENT_GLOBAL_RESUME_STANDBY=
"restore_after_standby"
Custom Battery States
In the file /etc/sysconfig/powersave/battery, define three battery charge
levels (in percent) that trigger system alerts or specific actions when they are reached.
BATTERY_WARNING=12
BATTERY_LOW=7
BATTERY_CRITICAL=2
The actions or scripts to execute when the charge levels drop under the specified limits
are defined in the configuration file /etc/sysconfig/powersave/events.
The standard actions for buttons can be modified as described in
"Configuring the powersave Package"
EVENT_BATTERY_NORMAL="ignore"
EVENT_BATTERY_WARNING="notify"
EVENT_BATTERY_LOW="notify"
EVENT_BATTERY_CRITICAL="wm_shutdown"
Adapting Power Consumption to Various Conditions
The system behavior can be adapted to the type of power supply. The power consumption
of the system should be reduced when the system is disconnected from the AC power
supply and operated with the battery. Similarly, the performance should automatically
(page 533).
