Removing AC power when laptop lid is closed doesn't suspend

Question

While the laptop lid is closed, when I remove external power, the laptop does not suspend so i have to open the lid and close to make it suspend.

When the laptop lid is open, then I remove power, then close, it works fine.

This used to work in Ubuntu 11.04.. Didn't work after upgrading to 11.10 and still not working now that I'm on 12.04

This is an annoying shortcoming in the current gnome-settings-manager (used to be gnome-power-manager). It does not check whether it should suspend when entering on-battery state. Here's a work-around:

Put the following into an (executable) file /etc/pm/power.d/zzsleepiflidclosed

#!/bin/sh 
# If the lid is closed, then sleep when we are switched to battery mode.
case "$1" in
    true) # Going into battery mode.
      sleep 1
      grep -q closed /proc/acpi/button/lid/*/state  &&  dbus-send --print-reply --system --dest=org.freedesktop.UPower /org/freedesktop/UPower  org.freedesktop.UPower.Suspend
      ;;
    false) # Going into line power mode
      ;;
    *)
        exit
        ;;
 esac
exit 0

I don't know why the sleep 1 pause is necessary, but without it, my lenovo won't resume stably.
