I don't know why most of the code is there.
An abbreviated version would probably work too.

I fetched this solution from somebody's web site
(http://individual.utoronto.ca/jaelle_kitty/inspiron6400)
and it worked for me, so I'm just passing it along.
I suspect there might be extra code (to go along with
other stuff) to support something like suspend.
