Bluetooth Not Working in Windows 10
If the Bluetooth on your computer is not working, you will not be able to use wireless keyboards, headphones, speakers, and other devices that can connect wirelessly with your computer via Bluetooth.
You should be able to use the troubleshooting steps provided below to get Bluetooth on your computer to work properly.
Make sure Bluetooth is enabled
Starting with basic troubleshooting steps, make sure that Bluetooth is enabled on your computer.
Go to Settings > Devices > select Bluetooth & other devices in the left-pane. In the right pane, make sure Bluetooth is turned ON.
Enabling and disabling airplane mode
Enabling and disabling airplane mode resets the Bluetooth network, which can help resolve Bluetooth connection issues.
Go to Settings > Network & Internet > select Airplane Mode in the left-pane. In the right pane, enable Airplane Mode by moving the toggle to ON position.
Wait for 30 seconds and disable Airplane Mode by moving the toggle to the OFF position.
Update Bluetooth Drivers
Right-click on the Start button and select Device Manager in the WinX menu. On Device Manger Screen, expand the entry for Bluetooth, right-click on the Bluetooth Adapter, and select the Update Driver option.
On the next screen, select the Search Automatically for Updated Driver Software option and allow Windows 10 to search for updated drivers and install them on your computer.
Run the Bluetooth troubleshooter
You can trust the built-in Bluetooth troubleshooter provided in Windows 10 to find Bluetooth connection problems on your computer.
Go to Settings > Update & Security > select Troubleshoot option in the left pane. In the right-pane, scroll down and click on Additional Troubleshooters. On the next screen, click on Bluetooth and then click on the Run the Troubleshooter button.
On the next screen, click on the Run the Troubleshooter option and allow Windows 10 to find and fix Bluetooth connectivity problems on your computer.
Remove the Bluetooth device and add it again
If a Bluetooth device such as a wireless keyboard, mouse, or headset is not detected, removing the Bluetooth device and adding it again can usually solve the problem.
Go to Settings > Devices > select Bluetooth & Other Devices in the left pane. In the right pane, select the Bluetooth device that is not working and click on the Remove Device option. Next, click on Add Bluetooth or other devices option.
Follow the onscreen prompts to Add the Bluetooth device back to your computer.
Check the status of the Bluetooth service
Sometimes, the problem is due to the system services related to Bluetooth being disabled or not being set to start automatically.
Right-click on the Start button and click on the Run. In the Run Command window, type:
services.msc and click on OK. On the Services screen, make sure Bluetooth Support, Bluetooth Handsfree, and other Bluetooth-related Services are running.
If any Bluetooth Service is disabled, double-click on the disabled service. On the next screen, set the Startup type to Automatic and click on the Start button.
Click on Apply and OK to close the Bluetooth Service Properties screen.
Apply Microsoft recommended fix
If your computer is still running Windows 7 or Windows 8, you need to apply the fix recommended by Microsoft to correct the PnP layer problem.
