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

Status in HWE Next Project:
  Invalid
Status in unity-settings-daemon package in Ubuntu:
  Fix Released

Bug description:
  * Impact
  the battery hotkey doesn't do anything

  * Test case:
  On a laptop with a special key for battery info press fn+f3
  -> the power info dialog should be displayed

  * Regression potential
  the action used before was buggy, having a valid one shouldn't create any issue

  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?
