Turn Bluetooth on or off
You can turn Bluetooth on to use Bluetooth devices and send and receive files, but turn it off to conserve power. To turn Bluetooth on, click the Bluetooth icon on the top bar and switch Bluetooth on.
Many laptop computers have a hardware switch or key combination to turn Bluetooth on and off. If the Bluetooth hardware is turned off, you will not see a Bluetooth icon in the top bar. Look for a switch on your computer or a key on your keyboard. The keyboard key is often accessed with the help of the Fn key.
To turn Bluetooth off, click the Bluetooth icon and switch Bluetooth off.
You only need to switch Visibility on if you are connecting to this computer from another device. See for more information.
