Turn of Bluetooth on the Dell XPS 13 - 9333

Turing off Bluetooth on the Dell XPS 13 is a real pain. Here is a quick guide on turning it off, keeping it off, saving battery power, and keeping your PC a bit more secure.

First disable the adapter, in a terminal:
sudo service bluetooth stop

To check in bluetooth is turned off or on, in a terminal type:
hciconfig

Now we need to keep the bluetooth adapter from turning back on when we reboot. Use your favorite editor (gedit, mousepad, nano, etc) to change the InitiallyPowered entry in your /etc/bluetooth/main.conf file from true to false.

In a terminal:
gksu mousepad /etc/bluetooth/main.conf

Look for the InitiallyPowered entry

Change:
InitiallyPowered = true

To:
InitiallyPowered = false

save and exit.
