Bug Description
CID: 201404-14986 Dell Precision M2800
The wireless slider on this system can't turn the Wifi off, but it could turn the BT on/off normally.
Steps:
1. Install 14.04.1 + update (3.13.0-37), boot to desktop
2. Try to turn the wifi off with the slider
Expected result:
* Both wifi and BT could be controlled by the wifi slider.
Actual result:
* Only BT could be turned off with the slider.
Wifi slider "ON"
