I felt like that when I couldn't configure GNOME to shutdown when I hit the power-button on my chassis, I could only pick to suspend.
It is not possible to change the power settings and it was removed by the GNOME developers[0] (the shutdown/power off action was considered too destructive[1]).
Bottom line: You can no longer power off your laptop by pressing the power off button.
