How do I disable my built-in bluetooth device?

My laptop bluetooth card is misbehaving and I no longer use it. I just plug in a USB dongle. Since the internal Bluetooth card serves no purpose, I would like to disable it completely.

I have already done my research and ended up writing the following udev rule:

SUBSYSTEM=="usb", ATTR{idVendor}=="13d3", ATTR{idProduct}=="3526", ATTR{authorized}="0"

This was from the following post: https://bbs.archlinux.org/viewtopic.php?id=297994

If I do

sudo udevadm control --reload-rules && sudo udevadm trigger

manually, then the rule works. However, it does not work on boot. Does it have something to do with systemd's bluetooth service?

Suggestions:

• Check if  your laptop has a physical toggle to turn its' bluetooth adapter off.

• /etc/bluetooth/main.conf  AutoEnable=false

• Checkout rfkill

• Blacklist the module.

Thank you for your suggestions.

- My laptop does not have a physical switch.
- AutoEnable=false is the default.

rfkill works but why does the udev rule fail?

Nope. This was once the default but was changed some time ago.
If there's a file named "main.conf.pacnew" you should see the change.
