Bluetooth is an integral part of your computer system. We use Bluetooth headset, mouse, and keyboards every day. It becomes a huge issue when Bluetooth suddenly disappears from your PC or device manager.

This article will discuss all fixes for when Bluetooth randomly disappears from your PC and Device Manager on Windows 10. The fixes explained in this post include:

  • Restart your computer
  • Update and reboot the operating system
  • Show hidden devices
  • Run the troubleshooter
  • Update Drivers
  • System File Checker (SFC) and DISM Scan
  • Restart Bluetooth support service
  • Use a USB Bluetooth adapter.

Fix 1: Restart Your Computer

The tech support’s mantra is restart and try again!

If you haven’t already tried that, restart your computer and turn on Bluetooth in the settings window.

To turn Bluetooth on in your system:

  1. Press the Windows key + I to open the settings window.
  2. In the settings window, click on Devices.
  3. Click on Bluetooth & Other Devices in the sidebar, and turn Bluetooth ON.

You should be able to see Audio and Other Devices listed under the Bluetooth toggle option. Connect the device and start using Bluetooth immediately.

Important: if you’re on a PC that requires a Bluetooth adapter to make a Bluetooth connection, the Bluetooth and Other Devices tab in the sidebar should be there. Here’s an example of the screen you should be seeing.

Fix 2: Enable Bluetooth with a Physical Key on the Keyboard

On most laptops, there is a dedicated key or a combination of keys to turn the Bluetooth on/off. Fn + f12 is the most common combination for turning Bluetooth ON/Off.

Check your keyboard for any specific or combination of keys to turn Bluetooth on/off. It’s quick and efficient. You can just click on/off instead of going through all the settings on the computer.

In some cases, Bluetooth cannot be turned on/off via software (only). It requires a combination of hardware and software.

If I accidentally (or otherwise) turn ON the Airplane mode in my computer, the Bluetooth is turned off automatically. To turn the Bluetooth back ON, I have to turn Off the Airplane mode first.

Important: Bluetooth does not work with the Airplane mode turned ON.

If your laptop has a key to turn on/off the Airplane mode, check that to make sure that you didn’t accidentally press that.

Fix 4: Update and reboot the operating system

A missing update on your computer can cause several issues. If the Bluetooth suddenly disappeared from your PC and device manager, it may be due to an update.

To update and reboot your operating system:

  1. Press the Windows key + I to open settings.
  2. In the settings window, click on Check for Updates.

If there are any available updates, download and install those and reboot your computer.

In case there are no available updates, try restarting your system. This solution works for most relevant issues.

Fix 5: Update Drivers

In most cases, when a device is malfunctioning, we just update the drivers. This case is different; how do you update a driver when you can’t see the device?

The standard approach to solve this dilemma is updating all USB drivers.

To update all the USB drivers:

  1. Press Windows key + R and type devmgmt.msc in the Run dialog box.
  2. In the device manager, scroll down to the bottom of the driver’s list and click on Universal Serial Bus controllers.
  3. You will see a bunch of USB devices listed under the Universal Serial Bus controller.
  4. Update each USB driver one by one and then reboot your system.

Fix 6: Run the Bluetooth Troubleshooter

Windows 10 comes equipped with a lot of unique features and apps. Those applications protect the system from potential threats and fight against it. An example of such applications would be Windows 10 Antivirus and troubleshooter.

You don’t need to use any third-party Antivirus software to keep your system safe.

On the other hand, the troubleshooter can resolve a lot of issues in your computer. Troubleshooter is especially helpful with built-in apps and services like Bluetooth.

To open and run the troubleshooter:

  1. Open the start menu and type troubleshoot in the search bar.
  2. From the given options, select Find and fix problems with Bluetooth devices.
  3. Click next in the troubleshooter window and follow the given instructions (if any) to resolve the issue.

Fix 7: System File Checker (SFC) and DISM Scan

The SFC (System File Checker) scans the system for corrupt files and repair them. If the files related to the Bluetooth feature are corrupted, you can scan to find and resolve them.

To run the system file checker:

  1. Open command prompt (cmd) with admin privileges.
  2. Type the following command in the cmd window.
    sfc/scannow
  3. If Bluetooth is still missing after running this command, then try the DISM (Deployment Image Servicing and Management) commands (in the same order as follows):
    DISM /Online /Cleanup-Image /CheckHealth
    CheckHealth: checks for corruption.
    DISM /Online /Cleanup-Image /ScanHealth
    ScanHealth: used when the checkHealth command fails to find the error.
    DISM /Online /Cleanup-Image /RestoreHealth
    RestoreHealth: restores corrupt files

Fix 8: Restart Bluetooth support service

Stopping or disabling the Bluetooth Service can result in several issues. You may not be able to find your device, pair, or associate with it. Restarting the Bluetooth support service can fix this issue.

To restart Bluetooth support services:

  1. Press Windows key + R and type “services.msc” in the dialog box.
  2. In the Services window, right-click on Bluetooth Support Service and select:
    a) Start: if it is not running.
    b) Restart: if it’s already running (and wait for a few seconds)
  3. Check for Bluetooth and if it worked, right-click on the Bluetooth Support Service and select Properties in the dropdown menu.
  4. In the properties window, General tab, choose Automatic as the Startup Type.

Now, your computer will automatically repeat this step each time it’s booted.

Fix 9: Use a USB Bluetooth Adapter

On desktop computers, you will require a Bluetooth adapter to connect Bluetooth devices. The Bluetooth adapter is readily available anywhere online, but it’ll permanently occupy one USB slot to it.

Fix 10: Show Hidden Devices

When there are multiple devices installed on your computer, you may not be able to see some of them on the device manager. In this case, the ‘show hidden devices’ option can help.

To show hidden devices in device manager:

  1. Open device manager by pressing Windows + R keys, typing ‘devmgmt.msc,’ and hit enter.
  2. In the device manager, click on the View Option and select Show Hidden Devices.

The list of devices gets extended, and you can see the primary category name only. Go through the list and check if the Bluetooth device is hidden for some reason.
