If you don’t use you Bluetooth on your laptop then you might want to disable it. Firstly it’s another service your computer does not have to start up when it boots and secondly it will use less power.

For all the following commands you will probably need root access, i.e. you may need to prefix “sudo”.

To stop the bluetooth service use the following command.

/etc/init.d/bluetooth stop

Now lets remove the Bluetooth services from starting when you boot up:

update-rc.d bluetooth remove

Unfortunately Bluetooth support is build into the Kernal itself, but the following line should prevent the Kernel from loading up:

echo 'alias net-pf-31 off' >> /etc/modprobe.conf

That’s it, all done. When you reboot Bluetooth should not restart itself any more.
