[gentoo-user] preventing PC sutdown by power button when running

How to prevent PC from shutdown when running when power button is pressed?
Is it a function in a BIOS or OS?

When booted, OS.
But the 5s press is BIOS.

Press and release, in less than four seconds, is the OS.  Four seconds 
or longer is the BIOS.

Try stopping acpid and seeing if that gets you the desired results.

If you want to be able to disable the whole switch, you could try adding a "killswitch".

Nowadays (e)logind handles that. Setting 
  HandlePowerKey=ignore
in /etc/elogind/logind.conf should disable that (haven't tested).

Kind regards, tastytea

Thank, will definitely try it and let you folks know.
But right now, I've managed to break the boot-loader, so this is the
priority.

You could always unplug the wire from the power button to the motherboard.

I've also seen where people had two or more switches in series and they
all had to be pressed at the same time to power off.  I've seen people
do that with reset buttons too.  It's just a momentary switch and ebay
has them by the dozen pretty cheap.  It's effective.

But, if one wants to really disable it, your way is easiest.  It just
depends on how far a person wants to go with this.

That seems like the simple, obvious solution to me.

Of course it makes it a bit difficult to turn the PC _on_ after it's
been powered down unless you change the BIOS to "always on after power
interruption", then you can turn it on by toggling the AC power.
