Some PC computers come with built-in Bluetooth while others don’t. Other times the built-in Bluetooth can stop working and needs to be fixed or replaced.
Having no Bluetooth can be annoying, especially when a device such as a headset, speakers, or keyboard needs Bluetooth to work.
If your computer has no Bluetooth or it no longer works, it is an easy task to fix that almost anyone can do.
2 Ways to Add Bluetooth to a Computer
- Use a Bluetooth USB Dongle
- Add an Internal Bluetooth Card
Most choose to buy a Bluetooth dongle as they are cheap, easy to setup, and work with most any computer.
They also work with either a desktop or laptop making them ideal for quickly adding Bluetooth ability.
Internal Bluetooth cards can also be installed which have the added benefit of often being faster, having better range, and out of the way not taking up a USB slot.
Installing an internal card will not be for everyone and most will simply buy a USB dongle.
How To Check a Computer if Bluetooth Device Already Installed
Before buying any Bluetooth adapter, check if your computer already has a Bluetooth device installed.

You can also look in Device Manager to see if Bluetooth is available.
