Hello
Your question is actually quite unclear.
Can you please clarify a few things so that the instruction given to you can be more specific?
Are you trying to connect to a certain Bluetooth device, such as your headset or speaker, but running into issues?
Or it doesn't matter; it is more in general that you cannot connect to ANY Bluetooth device?
Or are you having trouble even finding the Bluetooth option in your computer settings?
If you do run into error, please include error message. These scenarios can determine the troubleshooting steps, and they can be quite different; hence, clarification is much needed. Thanks!!
