1 Answer

Answer :

answer:Possibly scanning the area for devices? Personally, I have never had a use for the bluetooth on my laptop, and thus leave it off at all times. My mouse has it’s own USB receiver, my phone hooks up via US or wifi, I don’t use a headset, my printer is wifi…. basically useless to me.
