The 'Do Nothing' Option for power button in system power options!

[kaspro]

Hello, i've tried to set the option for pressing the power button to 'Do Nothing' so no body can shut the computer, and yet it shuts down by pressing the button, so why is that and how can i work this out?
Thank you.

Make sure you have the ACPI drivers properly installed. Set the same thing on the sleep button as they may be one in the same.
