acpid is usually packaged with a script which contains as an action a line
"shutdown -h now". acpid runs this script every time, when a power button is
pushed. HAL notices that the power button is pressed and this information sends
to DBus. Bud if there is no application which would listen on DBus and catches
this event, nothing will happen. Applications which catch this kind of event on
DBus are for example gnome-power-manager or kpowersave.
