+.Sh SYNOPSIS
+.Nm
+.Op Fl h
+.Op Fl i Ar batt
+.Op Fl k Ar ack
+.Op Fl s Ar type
+.Sh DESCRIPTION
+The
+.Nm
+utility allows the user control of the ACPI power management
+functions.
+The following command-line options are recognized:
+.Bl -tag -width ".Fl s Ar type"
+.It Fl h
+Displays a summary of available options.
+.It Fl i Ar batt
+Get design information about the specified battery.
+.It Fl k Ar ack
+Ack or abort a pending suspend request using the argument provided.
+.Sy Most users should not use this option directly.
+.It Fl s Ar type
+Enters the specified sleep mode.
+Recognized types are
+.Cm 1
+(only the CPU clock is stopped),
+.Cm 2
+(not implemented on most systems but similar to S1),
+.Cm 3
+(the CPU context is lost and memory context is preserved),
+.Cm 4
+(the CPU context is lost and memory context is stored to disk)
+and
+.Cm 5
+(soft off).
+Sleep states may also be given as S1, S2, etc.
+The supported states depend on BIOS implementation, including ACPI
+byte code (AML).
+If the

+and
+.Pa /etc/rc.resume
+scripts are executable, they will be run before and after entering
