/etc/sysconfig/powersave/sleep
In this file, activate the sleep modes and determine which critical modules should
be unloaded and which services should be stopped prior to a suspend or standby
event. When the system is resumed, these modules are reloaded and the services
are restarted. You can even delay a triggered sleep mode, for example, to save files.
The default settings mainly concern USB and PCMCIA modules. A failure of
suspend or standby is usually caused by certain modules. See
"Troubleshooting"

29.5.2 Configuring APM and ACPI
Suspend and Standby
There are three basic ACPI sleep modes and two APM sleep modes:
Suspend to Disk (ACPI S4, APM suspend)
Saves the entire memory content to the hard disk. The computer is switched off
completely and does not consume any power. This sleep mode is enabled by default
and should work on all systems.
Suspend to RAM (ACPI S3, APM suspend)
Saves the states of all devices to the main memory. Only the main memory continues
consuming power. This sleep mode is disabled by default because still causes
problems on some systems. However, support has been extended greatly.
