You're in luck!  I maintain the acpid package *and* my notebook is a
Dell Inspiron 6400.

I use the default handler.sh file for my stuff, found in /etc/acpi.  I
have the lid closure trigger a suspend-to-ram:

    button/lid)
        #echo "LID switched!">/dev/tty5
        grep -q closed /proc/acpi/button/lid/*/state
        if [ $? = 0 ]; then
            echo -n mem >/sys/power/state
        fi
        ;;

You can easily replace "echo -n mem >/sys/power/state" with any of the
following, depending on your desired result:

    xset dpms force off
    xscreensaver-command -lock
    etc.
