Press and hold in for 3-5 seconds, that is a hard shutdown if it wont turn off

What happens now when you press the power button?  What does your syslog
say?

First of all, you need an ATX motherboard.  (Any motherboard newer than
about 7/8 or so years ago).  Then you need ACPI compiled into your
kernel, as well as `emerge acpid`.

Finally, if it still doesn't work, post what you see from
tail -f /var/log/messages
or whatever your syslog is, when you press the power button.

post back if that doesn't work!

and you're done!  The default configuration for acpid includes a handler 
for the power button event.

Only a small addition to Mr. Iain Buchanan's reply.

You have to activate "button" under ACPI in the kernel:

cd /usr/src/linux && make menuconfig
 -> Power management options (ACPI, APM) ->
 ACPI (Advanced Configuration and Power Interface) Support
       -> Button <*> ---- here say "YES"

After emergeing acpid and runing it, you should have "shutdown now"
mapped to your power button.

I have this activated, but nothing happens other than the unhandled event

I would rather have hibernate mapped to it.  How?

PS. I think that sleep (save to RAM) does not work on this laptop, not when X 
is running anyway.

Thanks!  I hadn't spotted this article.  I've tried adding the following two 
lines in /etc/acpid/event/default but nothing much happened (as per the log 
further down):

event=button[ /]power.*
action=/usr/sbin/hibernate-ram

This is the log:
========================================

It's as if the two lines I've added were ignored.

button/power and button/sleep are _not_ the same and as the log tells
us, it's a button/sleep event. If I get this right, in your
configuration, only a button/power is handeled.

No it doesn't really.  The default entries in mine were as you show above.  I 
just followed the comments in the file to separately define what should 
happen when the power button is pressed, but it didn't work anyway.

You need to add a "sleep" case here to do whatever you want to happen
when you press the pwer button...

>                         *)      log_unhandled $* ;;

...or this case is executed.  The "log_unhandled" function generates a
message in the form of:

ACPI event unhandled: button/foo

Sound familiar? ;-)

So if you want power to shutdown nicely, try adding:

                        sleep)
                                /sbin/init 0

Just a slight hijacking of this topic,
	I have a little EPIA server acting as firewall, npt, dhcp, dns,etc,etc. 
Now even though it doesn't pull a lot of power, I don't want it running 
all the time, it has something to do with missing ice caps. So I want to 
build a button that attaches to the machine via, say, usb that when 
pushed shuts the machine down. By a button I mean that sort of emergency 
shutdown button that is usually red and used in industrial control, the 
sort of thing the hero always has to push to save the heroine/world.

	Does anyone here have enough hardware design knowledge to say if this 
would be easy or not and as to whether I should just lower my sights and 
stick to the three finger salute or the "normal" on/off switch?

	Regards,
		Andrew

p.s. The main reason driving this is that the wife never turns the 
server off. If I have a Big Red Switch, I can say "But it has a big red 
switch, how can you miss it????"

Thanks Richard,

I have added this:

and it now hibernates nicely.  I have another acpi event question, but I'll

I hope my question and answers I received have satisfied the OP requirements

Re: The Big Red Button - was Re: [gentoo-user] Power butten

[William Kenworthy]

use a usb mouse - dismantle it and use your big red button to close the
left mouse switch (or better one of the aux ones if they exist).  Map
this to shutdown the system.

don't know about the James Bond stuff - you'd probably also need an lcd
countdown where the button only works if you press it on 007...

anyway, you probably don't want to go exactly the way of the industrial
Emergency Stop, as it's a hardware cutoff - ie. power is shut of
straight away, without any software intervention.  Your disks will
probably survive the unclean unmounts, and you power supply may handle
the voltage / frequency spikes from the switch opening, but why bother?

If you really want, you can pick them up from any electrical distributer
(in Australia anyway)...

If I were you, I'd want to stay with the ACPI power button, most popular
OS's can detect this nicely.  What you can do is this:

- "splice" the power switch cable (the motherboard/case one, NOT the
power supply side!).  The button works by completing a circuit to the
motherboard when pressed, so you can have two buttons doing the same
thing on the same circuit.  Join a new wire of each of the two existing
wires. (Inside your case, they're usually labelled PWRSW or something).
- buy any sort of big red button (normally open, non latching) and wire
it to the two new wires.  I have a nice arcade "fire" button which would
do the trick.
- stick it on the top / front of your case with a sign saying "PRESS
ME" (or maybe "don't touch" if you want to go for the reverse psychology
angle...)

voila!

you could try some "reNedufication", or perhaps a script that detects
how many users are logged in and for how long, and then shutdown
automatically.  Or just shutdown at midnight (or whatever time she's
guaranteed not to be on...
