This one seem to be working for me:

  #!/bin/sh
  if grep closed /proc/acpi/button/lid/LID0/state &>/dev/null
  then echo "Lid closed, suspending..."
  else echo "Lid is open, doing nothing"
  fi


Then, you can just put it to, say, crontab, with a line like this:

  */5 * * * * /path/to/script.sh

...which'll make it run every five minutes, so the laptop will be
suspended within five mins of closing the lid, which should also
prevent accidental closing events.


Of course, you should put your actions to the aforementioned script, if
you want it to do something useful, instead of just experimental echo.
