Fix 1: How to Fix Windows 10 Bluetooth Turn On Button Missing by Updating Drivers
As explained above, you can update your Bluetooth drivers using a driver updater like Driver Booster, or you can uninstall your driver in the device manager and then install the latest Bluetooth driver package available on the Intel website.
How to Update Bluetooth Drivers using a Driver Updater
The easiest method to update your Bluetooth drivers is using a driver updater, as they always find the latest version available and also allow you to update multiple drivers at once.
To fix your Bluetooth turn on button missing:
- Download Driver Booster and install it on your PC.
- Open Driver Booster and click on the Scan button:
- Now select all the Bluetooth drivers on the outdated list by clicking on the checkbox next to it, then click on the Update Now button:
If you want to update only the Bluetooth drivers, you can uncheck the other non-Bluetooth drivers, But we recommend updating all your drivers at once, except the network adapter drivers.
- Now confirm and wait for the update to finish.
How to Manually Update Bluetooth Driver
This method does not require you to install any software, but it might need a lot of time if you want to update multiple drivers.
- Enter Device Manager on Windows search, then click on the first result:
- On the View Tab, click on Show Hidden Devices:
- Click on Bluetooth to expand the Bluetooth devices, and uninstall the Intel(R) Wireless Bluetooth(R) driver:
- Download and install the latest Intel(R) Wireless Bluetooth(R) driver from Intel’s official website:
We will download the driver from Intel’s official website instead of updating it through Device Manager because Windows 10 often reports that you have the latest driver while you don’t. So, we want to make sure you got the latest driver.
If this didn’t work, you could also try the solutions below that worked for several users.
Fix 2: Uninstall all Bluetooth-related software on Programs and Features
If updating the drivers didn’t work, you can try to uninstall all Bluetooth-related software on Windows 10 Programs and Features, then reboot your PC so Windows can reinstall the right software. This is how you can do it:
- Press Windows Key + R and type appwiz.cpl, then press Enter to open Programs and Features:
- On Programs and Features, enter Bluetooth in the search box to filter all Bluetooth-related software:
- Uninstall all Bluetooth-related software, then restart your PC.
If the Bluetooth still doesn’t work, try running the Bluetooth Troubleshooter:
Fix 3: Run the Bluetooth troubleshooter
Windows 10 comes with a series of troubleshooters to fix common problems, including a troubleshooter made specifically to fix Bluetooth issues.
To run the Bluetooth troubleshooter:
- Enter Settings on Windows Search and click on Open:
- On Settings, click on Update & Security:
- Select Troubleshoot on the left sidebar, and under Bluetooth, click on Find and fix other problems Run the troubleshooter:
- Click on Run the troubleshooter, then follow the instructions.
If this also didn’t work, try turning off Fast Startup.
Fix 4: Turn off Fast Startup to Fix Bluetooth Issues
According to Microsoft’s official website, Fast Startup is a feature enabled by default on Windows 10 and helps your PC boot faster. It works by putting your computer into a hibernation state instead of a full shutdown.
While not seemingly related, turning off fast startup can help you fix Bluetooth issues.
This is because fast startup has been associated with hardware issues, and sometimes just turning it off can fix certain PC problems, including Bluetooth issues.
Follow the steps below to turn it off:
- Press Windows Key + R and type powercfg.cpl, then press Enter to open Power Options:
- On the left side of Power Options windows, select Choose what the power buttons do:
- Click on Change settings that are currently unavailable to enable the shutdown settings which are greyed out:
- Uncheck the Turn on fast startup box, then click on Save Changes:
- Turn your PC off and then on again.
If you don’t want to disable fast startup, you can also perform a full shutdown by holding the SHIFT key when you click on Shut Down on the Start Menu.
Now check if your Bluetooth devices are functioning correctly. If nothing else worked, consider resetting your Bios.
Fix 5: Reset the Bios
Many users also reported that resetting the Bios worked for them. This works if Windows Update ends up changing some settings in the BIOS. In this case, resetting the BIOS will make your PC recognize Bluetooth devices again.
This is an advanced fix; only try it if you are sure you understand what you are doing.
To reset your Bios:
- Enter Settings on Windows Search and click on Open:
- On Settings, click on Update & Security.
- Click on Recovery on the left sidebar, and then select Restart now under Advanced setup:
- Your PC will restart, and it will appear a blue screen. Select Troubleshoot:
- Under Troubleshoot, click on Advanced Options:
- Select UEFI Firmware Settings, then click on the Restart button to reset your Bios:
The best thing you can do to fix your Bluetooth issues (and avoid hardware issues) is to update your device drivers. Other solutions that worked very well for users are turning off Fast Startup and resetting the Bios.
Besides keeping your drivers updated, the next best thing you can do is to uninstall all programs you don’t want to use to free disk space and RAM on your PC.
