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 control 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 
 
...
