Device Manager Missing Bluetooth

Missing Bluetooth in Device Manager usually means one of a few things: the adapter may be hidden, disabled, have a driver issue, or be absent from the PC. If Bluetooth is not listed in Device Manager, first confirm the device actually supports Bluetooth. Checking the wrong cause can waste time and keep earbuds, mice, and file transfers out of reach. This guide shows how to tell which case applies on Windows 10 and 11, then follow the right fix for laptops, desktops, and Surface PCs.

Common causes and initial triage steps

If the Bluetooth category vanished, split the problem into four cases: the adapter is hidden, the Bluetooth service is stopped, the driver is damaged, or the PC has no Bluetooth hardware. Start in Device Manager with hidden devices shown. That tells you whether Windows can still see the radio at any level.

Likely causes

Most often, the cause is hidden devices, a bad driver, or a service problem. Less often, Airplane mode or a firmware setting turns the radio off. If none of those restore Bluetooth, the adapter may be missing from the machine or failed.

Bluetooth decision table

Is Bluetooth actually supported on your PC?

If Device Manager has no Bluetooth category, confirm the hardware first. Some desktops and older towers do not include Bluetooth unless you add a USB Bluetooth adapter.

1. Open Start search, type device manager, and open it.
2. Expand Network adapters and Other devices as well as Bluetooth.
3. Look for entries such as an Intel, Realtek, Broadcom, or Qualcomm wireless adapter that also handles Bluetooth.
4. Check the PC maker’s specs page for the exact model.
5. If it is a desktop without built-in Bluetooth, plug in a USB Bluetooth adapter and restart.

Say your 27-inch desktop has Wi-Fi through an add-in card but no Bluetooth entry anywhere. That points to a machine that needs a USB Bluetooth adapter or a replacement wireless card with Bluetooth support, not a driver tweak.

How do you show hidden devices in Device Manager?

Hidden devices are the next check because Bluetooth can drop out of the visible list while still sitting in a ghosted state. In Device Manager, check the View tab for a tick mark beside Show Hidden Devices, and click Show Hidden Devices to reveal hidden Bluetooth devices.

1. Open Device Manager.
2. Select View > Show hidden devices.
3. Expand Bluetooth, Network adapters, and Other devices.
4. Right-click the PC name at the top, then choose Action > Scan for hardware changes.
5. If Bluetooth appears, right-click the adapter and check whether it is disabled or has an error icon.

A common mistake is assuming Bluetooth is gone just because the Device Manager tree looks incomplete after a driver update. If Bluetooth is hidden under Other devices, Windows may still be detecting it but failing to bind the correct driver.

How do you repair the Bluetooth driver?

Driver damage is common after a Windows update, driver swap, or restart. Run the Windows Bluetooth troubleshooter in the Get Help app, then uninstall the adapter and let Windows reinstall it; if that does not work, install the latest driver from the PC maker’s support site and restart.

1. Run the Windows Bluetooth troubleshooter in the Get Help app.
2. Open Device Manager, expand Bluetooth, right-click the adapter, and choose Uninstall device > Uninstall.
3. Shut down the PC.
4. Turn it back on.
5. If Windows does not reinstall it, return to Device Manager and choose Action > Scan for hardware changes.
6. If the driver still looks broken, install the latest Bluetooth driver from the PC manufacturer’s support website and restart.

Win+X > Device Manager > (Bluetooth adapter) > right-click > Properties > Driver tab
Actions:
- Update driver
- Roll Back Driver
- Uninstall device
- check "Delete the driver software" when reinstalling a corrupted driver
If Windows Update has no newer package, download the driver from the OEM or chipset vendor site.

Why is Bluetooth missing after a reboot or update?

If Bluetooth vanished after a reboot, update, or power loss, check the service layer and the radio switches before chasing driver files. Open the Services app, right-click the Bluetooth Support Service, open Properties, and click Start if the service is disabled. If needed, perform a power flush. Windows 11 users should also check Quick settings, while Windows 10 users should check the action center or Network & internet.

1. Open services.msc.
2. Find Bluetooth Support Service.
3. Open Properties, set Startup type to Automatic, then choose Start or Restart.
4. Turn off Airplane mode in Settings > Network & internet on Windows 11, or in action center on Windows 10.
5. On Windows 11, check Settings > Bluetooth & devices and the Quick settings Bluetooth tile.
6. If the problem started after a firmware change, review BIOS/UEFI wireless settings before reinstalling the driver again.

Suppose a laptop comes back from sleep with Wi-Fi working but Bluetooth gone. If Airplane mode was switched on, the adapter may disappear until you turn that switch off and restart.

What if Bluetooth disappeared from Device Manager after an update?

When the category vanishes after an update, check service state, scan for hardware changes, and then install the vendor package if Windows restores the wrong or incomplete driver. Check Windows Update for driver updates, then download and install the latest Bluetooth driver from the PC manufacturer’s support website and restart if Windows cannot sort it out.

1. Open Settings > Windows Update and check for updates.
2. Install any optional driver updates that mention Bluetooth or wireless.
3. Return to Device Manager and select Action > Scan for hardware changes.
4. If Bluetooth returns with a warning icon, uninstall that adapter and let Windows reinstall it.
5. If the issue remains, install the latest OEM Bluetooth driver and restart.

Can Airplane mode make Bluetooth disappear from Device Manager?

Yes. Airplane mode can turn off wireless radios, and that can make Bluetooth devices disappear from Device Manager until the radio is turned back on. On Windows 11, the toggle is usually in Quick settings or Settings; on Windows 10, it is usually in action center or Network & internet.

1. Open Quick settings on Windows 11 or action center on Windows 10.
2. Turn Airplane mode off.
3. Open Settings > Network & internet and confirm wireless is enabled.
4. Restart the PC.
5. Check Device Manager again for the Bluetooth category.

How do I check if my PC actually supports Bluetooth?

Start with the model specs from the PC maker, because some machines do not include Bluetooth hardware. Microsoft says that if Bluetooth is not listed in Device Manager, the first step is to confirm support, since some devices do not have Bluetooth at all.

1. Find the exact model number on the PC label, packaging, or system page.
2. Open the manufacturer’s support page for that model and look for Bluetooth in the wireless section.
3. Open Device Manager and check Bluetooth, Network adapters, and Other devices.
4. If it is a desktop with no built-in radio, use a USB Bluetooth adapter.
5. If the PC maker lists Bluetooth and Windows cannot see it, move on to driver and firmware checks.

Bluetooth verification checklist

After a fix, verify more than one screen. A working adapter should return in Device Manager, appear in Windows Bluetooth settings, and allow a pairing test. If any one of those fails, keep troubleshooting instead of assuming the issue is solved.

1. Confirm Bluetooth appears in Device Manager without a warning icon.
2. Confirm Settings > Bluetooth & devices shows the radio as available.
3. On Windows 11, confirm the Bluetooth tile exists in Quick settings.
4. Pair a small test device, such as earbuds or a mouse.
5. If the adapter appears but pairing fails, remove the device in Settings > Bluetooth and devices > Devices and pair it again.

Still not working?

If Bluetooth still does not redetect after hidden-device checks, service restarts, driver reinstall, Airplane mode checks, and BIOS/UEFI review, stop repeating the same steps. At that point, the problem is usually OEM-driver specific or hardware-related. On laptops and Surface devices, vendor support is the best next step; on desktops, a USB Bluetooth adapter or replacement wireless card is often the practical fix.
