If your energy saving’s power button action setting for “When power button is pressed” in AC Power and Battery Power is being ignored, you can comment two lines in /etc/acpi/acpi_handler.sh to fix this issue:
Comment:
# power) /sbin/init 0 # ;;
Commented out /etc/acpi/acpi_handler.sh:
#!/bin/sh
# Default acpi script that takes an entry for all actions
IFS=${IFS}/
set $@
case "$1" in
button)
case "$2" in
# power) /sbin/init 0
# ;;
*) logger "ACPI action $2 is not defined"
;;
esac
;;
*)
logger "ACPI group $1 / action $2 is not defined"
;;
esac
No reboot necessary, it should be fixed instantly.

Betteridge’s law of headlines is an adage that states: “Any headline which ends in a question mark can be answered by the word no.” It is named after Ian Betteridge, a British technology journalist, although the general concept is much older. The observation has also been called “Davis’ law” or just the “journalistic principle”.
