This page explains how to configure the action(s) taken by your system when you press the power button on your PC.


== Configure Power Button Action ==

When the power button is pressed on your PC, the ACPI daemon consults the following file to determine what action to take:

  '''/etc/acpi/events/powerbtn-acpi-support'''

This in turn passes control to:

  '''/etc/acpi/powerbtn-acpi-support.sh'''

This script is therefore the best place to configure the action(s) taken when the power button is pressed.  For example, in '''antiX 17.1''', the command executed by '''/etc/acpi/powerbtn-acpi-support.sh''' is handled by this block of code:

{{{
if [ -x /etc/acpi/powerbtn.sh ] ; then
        # Compatibility with old config script from acpid package
        /etc/acpi/powerbtn.sh
elif [ -x /etc/acpi/powerbtn.sh.dpkg-bak ] ; then
        # Compatibility with old config script from acpid package
        # which is still around because it was changed by the admin
        /etc/acpi/powerbtn.sh.dpkg-bak
else
        # Normal handling.
        /sbin/shutdown -h -P now "Power button pressed"
fi 
}}}

So, for example, if you want a laptop to sleep rather than shutdown when you press its power button, you would change the final section of this code block to the following:

{{{
else
        # Normal handling.
        /usr/sbin/pm-suspend                      
fi 
}}}

This change can be effected by editing the file with '''nano''' using the following command:

  $ sudo nano /etc/acpi/powerbtn-acpi-support.sh
