  CID: 201308-14073 Lenovo T440s

  The wireless hotkey can only control the wireless network, it can't
  control the Bluetooth.

  Steps:
  1. Install 14.04 + update (3.13.0-40)
  2. Turn BT off with the wireless hotkey

  Expected result:
  * Bluetooth can be controlled by the wireless hotkey.

  Actual result:
  * Only wireless network will be turned off.
