How to drive an hidden bluetooth on my laptop

What do you mean it's hidden ? Go into device manager and ifyou have blue tooth then it will be in there , if you have a Dell computer then look on the bottom of the laptop and you'll see a service code that you can enter when you go to the Dell support page. This will bring up your computer and everything that's in it and the drivers that are needed, you can then download the blue tooth driver and install it and then it won't be hidden any more.
