Title:
  Battery hot key does not bring up the power management dialog in
  Trusty

Bug description:
  CID: 201209-11840 Dell L322X

  The battery hotkey on this system (fn+f3) cannot bring up the power management dialog.
  Also verified with 14.04.2 on LiveUSB, it's not working as well.
  But it works with 12.04.5 on LiveUSB. (Maybe it's user-space related?)

  It seems that the key event could be detected properly, it could pass
  our checkbox test (which will check the '0xe071,0xef1:Battery Info'
  signal)

  ubuntu@201209-11840:~$ sudo showkey -k
  kb mode was ?UNKNOWN?
  [ if you are trying this under X, it might not work
  since the X server is also reading /dev/console ]

  press any key (program terminates 10s after last keypress)...
  keycode  28 release
  keycode 240 press
  keycode 240 release
  keycode 238 press
  keycode 238 release
  keycode  29 press
  ^Ccaught signal 2, cleaning up...
