Title:
  Shutdown doesn’t turn the PC off

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Shutting down the system from Unity by clicking the gear icon at the
  top right of the screen, selecting the shutdown option, and then
  clicking the shutdown icon at the center of the screen, doesn’t turn
  the PC off.

  The shutdown process is initiated and the screen with the Ubuntu logo
  at the center and a solid background color appears, but the PC remains
  on. I have to manually operate the PC's power switch to turn it off.
  Selecting the restart option rather than a shutdown doesn’t restart
  the PC either, same behavior.

  Issuing a shutdown or reboot from a shell with the "sudo shutdown -h
  now" or "sudo shutdown -r now" command seems to consistently complete
  the procedure and work correctly.

  Until upgrading from Ubuntu 12.10 to 13.04 on the same hardware a
  couple of days ago, this feature worked correctly. The problem might
  be related to some frequent instability issues I reported in bug
  #1176061:

  Random system freezes
