control ACPI power management
utility allows the user control of the
ACPI power management functions. The following command-line options are
- Displays a summary of available options.
- Get design information about the specified battery.
- Ack or abort a pending suspend request using the argument
provided. Most users should not use this option
- Enters the specified sleep mode. Recognized types are
1 (only the CPU clock is stopped),
2 (not implemented on most systems but
similar to S1), 3 (the CPU context is lost
and memory context is preserved), and 4 (the
CPU context is lost and memory context is stored to disk). Sleep states
may also be given as S1, S2, etc. The supported states depend on BIOS
implementation, including ACPI byte code (AML). If the
/etc/rc.resume scripts are executable, they
will be run before and after entering the given sleep state.
