Disconnect a Bluetooth device
If you do not want to be connected to a Bluetooth device anymore, you can remove the connection. This is useful if you no longer want to use a device like a mouse or headset, or if you no longer wish to transfer files to or from a device.
- Go to the Desktop and start typing Bluetooth. 
- Click on Bluetooth to open the panel. 
- Select the device which you want to disconnect from the list. 
- In the device dialog box, switch the Connection switch to off, or to remove the device from the Devices list, click Remove Device. 
You can reconnect a Bluetooth device later if desired.
