Got tired of accidentally hitting the power button which is oh-so-close
to delete.

/etc/acpi/events/power :
...
# shut down when power button is pressed
event=button/power.*
action=/usr/local/sbin/halt-dialog

/usr/local/sbin/halt-dialog :
#!/bin/sh
export DISPLAY=":0.0"
RESULTS=`Xdialog --screen-center --default-no --yesno "The system is
about to shut down, do you want to continue?" 10 50`
EXIT_CODE=$?
case $EXIT_CODE in
        0) /sbin/halt
        ;;
        1) exit
        ;;
        255) exit
        ;;
esac

[EMAIL PROTECTED] jack]$ grep xhost .xfce/*
.xfce/xfwmrc:+ "I" Exec xhost +

Note that I use a local firewall to block X requests from the network,
if you don't have a firewall installed on your laptop you'd better make
that xhost +localhost. If you're using some window manager other than
XFce, put xhost in its startup, not XFce's :-)
