HP Envy 15 core i7 Linux - Howto resume after suspend

Bug #557072 in linux (Ubuntu): “system does not power off”

The following script works for me (saved as /etc/pm/sleep.d/5_quick-fix-drivers)
NB: The atl1c module is there because otherwise the ethernet controller didn't work after a resume. Remove it from the list if you aren't experiencing that problem.
