Fix Bluetooth Not Detecting Devices on Windows 10

This guide walks you through fixing Windows 10 when it fails to detect Bluetooth devices like headphones, keyboards, or mice. You’ll start with the quickest checks, then move through driver updates, services, and hardware troubleshooting until your device pairs successfully.

What You’ll Need

A Windows 10 PC or laptop with built-in Bluetooth (or a USB Bluetooth adapter)
The Bluetooth device you’re trying to pair (fully charged or with fresh batteries)
Administrator access to your Windows account
Optional: a USB Bluetooth adapter if your PC doesn’t have built-in Bluetooth

Step-by-Step

Turn on Bluetooth on your PC. Click the Start button, then Settings (the gear icon). Go to Devices > Bluetooth & other devices. Toggle Bluetooth to On. If the toggle is missing or grayed out, your PC may not have Bluetooth hardware or the driver is not installed.
Put your device in pairing mode. Most Bluetooth devices have a button or switch that puts them into discoverable mode. For headphones, hold the power button for 5–10 seconds until the LED flashes blue and red. For mice and keyboards, press the pairing button (often on the bottom). Check the device’s manual if unsure.
Start a new scan. In the same Bluetooth settings page, click Add Bluetooth or other device > Bluetooth. Windows will search for nearby devices for about 30 seconds. Your device should appear in the list. Click it to pair.
If nothing appears, restart Bluetooth on your PC. Toggle Bluetooth off and on again. Then re-enter pairing mode on your device and try the scan again.
Run the Bluetooth troubleshooter. Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters. Select Bluetooth and click Run the troubleshooter. Follow any prompts. This often fixes driver or service issues automatically.
Update your Bluetooth driver. Right-click the Start button and select Device Manager. Expand Bluetooth. Right-click your Bluetooth adapter (often named Intel, Realtek, or Qualcomm) and choose Update driver > Search automatically for updated driver software. If Windows finds nothing, go to your PC manufacturer’s support site and download the latest Bluetooth driver for your model.
Reinstall the Bluetooth driver. If updating doesn’t help, right-click the adapter in Device Manager and choose Uninstall device. Check Delete the driver software for this device if the option appears, then click Uninstall. Restart your PC. Windows will reinstall the driver automatically.
Check the Bluetooth Support Service. Press Windows + R, type services.msc, and press Enter. Find Bluetooth Support Service. Right-click it and select Restart. If it’s not running, right-click, choose Properties, set Startup type to Automatic, and click Start.
Remove old paired devices. In Bluetooth settings, if you see the device listed but it won’t connect, click on it and choose Remove device. Then put the device back into pairing mode and add it again.
Check airplane mode. Click the network icon in the system tray (bottom-right). If Airplane mode is on, click it to turn it off. Airplane mode disables Bluetooth on many laptops.
Verify Bluetooth hardware is present. In Device Manager, under Bluetooth, you should see an adapter. If you see an unknown device with a yellow exclamation mark, that’s likely your Bluetooth adapter. Right-click it and try Update driver. If there is no Bluetooth section at all, your PC may not have Bluetooth hardware; consider a USB Bluetooth adapter.
Use the hardware and devices troubleshooter. Press Windows + R, type msdt.exe -id DeviceDiagnostic, and press Enter. Follow the prompts. This checks for hardware-level problems.

Common Mistakes

Device not in pairing mode: Many users assume the device is discoverable when it’s just powered on. Most devices require a specific button press or holding the power button to enter pairing mode.
Bluetooth toggle off: The toggle can be turned off accidentally, or Windows may turn it off after a restart.
Multiple devices paired: Some devices can only remember one or two connections. If you’ve paired it with another phone or PC, it may not connect to your Windows machine until you unpair it elsewhere.
Outdated drivers: Windows Update doesn’t always provide the latest Bluetooth driver, especially for older laptops.
Interference: Other wireless devices (Wi-Fi, USB 3.0 hubs, microwaves) can interfere with Bluetooth. Move closer to the PC and away from other electronics.

Tips

Use the device’s manual: Pairing mode is not universal. Some devices blink slowly, others rapidly. Check the manual for the exact method.
Keep devices close: During pairing, keep the Bluetooth device within a few feet of the PC.
Charge your device: Low battery can prevent a device from entering pairing mode or being detected.
Restart both devices: A simple restart of your PC and the Bluetooth device (turn it off and on) resolves many temporary glitches.
Check for Windows updates: Go to Settings > Update & Security > Windows Update and install any pending updates. These often include Bluetooth fixes.

Troubleshooting

If the above steps don’t work, try these additional measures:

Check if the device works on another phone or PC. If it doesn’t, the device itself may be faulty.
Try a different USB port for the adapter. If you’re using a USB Bluetooth adapter, move it to a different port, preferably a USB 2.0 port on the back of the PC.
Disable and re-enable the adapter in Device Manager. Right-click the adapter and choose Disable device, wait a few seconds, then Enable device.
Check for BIOS/UEFI settings. Some laptops have a Bluetooth toggle in the BIOS. Restart your PC, enter BIOS (usually by pressing F2, F10, or Del during startup), and look under Wireless or Advanced to ensure Bluetooth is enabled.
Use the Command Prompt to restart the service. Open Command Prompt as administrator and run: net stop bthserv then net start bthserv. This restarts the Bluetooth service.
Check for third-party antivirus interference. Some security suites block Bluetooth. Temporarily disable your antivirus and try pairing again. If it works, add an exception.
If all else fails, consider a system restore. Go to Control Panel > Recovery > Open System Restore and pick a restore point from before the problem started.

Frequently Asked Questions

Why is my Bluetooth toggle missing in Windows 10?
This usually means your PC doesn’t have Bluetooth hardware, or the driver isn’t installed. Check Device Manager for a Bluetooth section. If it’s absent, you can add Bluetooth with a USB adapter.

How do I know if my PC has Bluetooth?
Open Device Manager and look for a Bluetooth section. Alternatively, check the bottom-right system tray for a Bluetooth icon. You can also go to Settings > Devices > Bluetooth & other devices – if the toggle is there, you have Bluetooth.

Why does my Bluetooth device pair but then disconnect immediately?
This is often due to power saving settings. Go to Device Manager, right-click the Bluetooth adapter, select Properties, go to Power Management, and uncheck Allow the computer to turn off this device to save power. Also check the device’s battery level.

Can I force Windows to detect a Bluetooth device?
Not really. Windows scans for devices in pairing mode. Ensure the device is in pairing mode and within range. Sometimes toggling Bluetooth off and on helps trigger a fresh scan.

Why does my Bluetooth device show as ‘Paired’ but not ‘Connected’?
This happens when the device is remembered but not actively linked. Click the device in Bluetooth settings and select Connect. If it fails, remove the device and pair again from scratch.

Does Windows 10 support all Bluetooth devices?
Most modern devices work, but very old or proprietary devices may require specific drivers. Check the manufacturer’s website for Windows 10 drivers or compatibility notes.

General steps for current mainstream versions; menus can differ by device and version. See the disclaimer or report an error.
