NAME
     acpilid -- ACPI Lid Switch

SYNOPSIS
     acpilid* at acpi?

DESCRIPTION
     The acpilid driver supports ACPI ``lid switches''.  The powerd(8) daemon can be used to con-
     trol actions against the events of opening or closing the lid.  The script used is
     /etc/powerd/scripts/lid_switch, and the events are either pressed (the lid was closed) or
     released (the lid was opened).

EXAMPLES
     The following example modifies the mentioned script in order to put the system into (S3)
     sleep when the lid is closed:

	   ...

	   case "${2}" in
	   pressed)
		   logger -p info "${0}: suspending..."

		   # As in sleep_button, kill some daemons.
		   #
		   /etc/rc.d/dhcpcd stop
		   /etc/rc.d/network stop
		   /etc/rc.d/wpa_supplicant stop

		   # Suspend.
		   #
		   if /sbin/sysctl hw.acpi.sleep.state >/dev/null 2>&1; then
			   /sbin/sysctl -w hw.acpi.sleep.state=3
		   fi

		   # Waking up.
		   #
		   /etc/rc.d/wpa_supplicant start
		   /etc/rc.d/network start
		   /etc/rc.d/dhcpcd start

	   ...
