.Sh DESCRIPTION
|
||||||
|
The
|
||||||
|
.Nm
|
||||||
|
utility
|
||||||
|
checks for ACPI or APM support and then suspends the system appropriately.
|
||||||
|
For APM,
|
||||||
|
.Pp
|
||||||
|
.Dl apm -z
|
||||||
|
.Pp
|
||||||
|
will be issued.
|
||||||
|
For ACPI, the configured suspend state will be looked up, checked to see
|
||||||
|
if it is supported, and
|
||||||
|
.Pp
|
||||||
|
.Dl acpiconf -s <state>
|
||||||
|
.Pp
|
||||||
|
will be issued.
