Why is there no Bluetooth found in Device Manager?

You can try these steps to fix the problem: Open Device Manager and uninstall the ‘Bluetooth’ device if it’s visible. Then download the latest drivers for your Bluetooth device from the manufacturer’s website. Make sure you restart your computer after installation. Another helpful method is to run the Windows Troubleshooter by going to ‘Settings’ > ‘Update & Security’ > ‘Troubleshoot’ > ‘Bluetooth’. This can help identify and fix underlying issues barring your Bluetooth functionality.

Here’s a method I used to fix this problem: First, go to Device Manager and select the ‘Action’ tab. Then, choose ‘Scan for hardware changes’ — this will prompt your system to detect any missing devices, including your Bluetooth adapter. If that doesn’t work, go to the ‘View’ menu in Device Manager and click on ‘Show hidden devices’. This will reveal any devices that might be hidden, including your Bluetooth device, which could be listed under ‘Bluetooth’ or ‘Network adapters’. Another essential step is to update your Bluetooth drivers from the manufacturer’s website. Lastly, if all else fails, check your BIOS settings to ensure the Bluetooth option is enabled. Save the settings and restart your computer.

You might find that a simple reboot or power cycle helps. For desktops, disconnect the power supply for a minute before plugging it back in. For laptops, shutdown, remove the battery if possible, and restart. These steps often reset hardware configurations, which might resolve the issue.

Sometimes, the issue is more serious and indicates hardware malfunction. In my experience, I had to replace my internal Bluetooth module. An easy and effective workaround is using an external USB Bluetooth adapter. Plugging it in usually installs the required drivers automatically and restores Bluetooth capability efficiently. This solution bypassed my faulty internal module and allowed all my Bluetooth devices to connect seamlessly.

When faced with this issue, I found it beneficial to ensure my Windows operating system was up to date. To update Windows, navigate to the ‘Settings’ app, click on ‘Update & Security’, and select ‘Windows Update’. Then press ‘Check for updates’. After updating, the Bluetooth functionality reappeared in my device manager. Keeping the system updated often resolves diverse issues, including hardware detection anomalies.

In my case, the root cause was related to the Bluetooth Support Service. To fix this, open the Run dialog using Windows + R and type services.msc, hitting Enter. Scroll to find Bluetooth Support Service, right-click it, and choose Properties. Set it to start automatically if it’s not already configured that way. If it is, stop and then restart the service. This action restored my Bluetooth device in the Device Manager after the service restarted successfully.
