Bluetooth Greyed Out in Device Manager: How to Restore It

Guide 10-29398 · Updated · Step by step

If Bluetooth is greyed out in Device Manager, the driver is disabled, blocked, or the radio is turned off—here’s how to restore it in a few minutes. Start by right-clicking the greyed Bluetooth adapter and selecting Enable device. If that option is missing or fails, work through the steps below in order; most cases are fixed by re-enabling the device, updating the driver, or turning the radio back on in Windows settings.

Why Does Bluetooth Appear Greyed Out?

Device Manager greys out a device when Windows recognizes the hardware but cannot use it. For Bluetooth, this usually means one of three things:

  • The adapter is disabled—either manually, by a BIOS/UEFI setting, or by a physical switch (common on laptops).
  • The driver is corrupted or incompatible—Windows may disable the device after a failed update or a conflict.
  • The radio is turned off in Windows—the “Bluetooth” toggle in Settings is off, or Airplane mode is on, which makes Device Manager show the adapter as greyed out even though the driver is fine.

Less common causes include a hardware fault (the adapter is dead or disconnected) or a Group Policy restriction on managed (work/school) computers. The steps below cover all of these, from simplest to most involved.

First Steps: Re-Enable and Check the Radio

Before touching drivers, try these quick fixes—they resolve a large share of cases.

  1. Enable the device in Device Manager: Press Win+X and select Device Manager. Expand “Bluetooth,” right-click the greyed adapter, and choose Enable device. If the option is greyed out itself, skip to the next step.
  2. Turn on Bluetooth in Windows Settings: Go to Settings > Bluetooth & devices and toggle Bluetooth to On. If the toggle is missing or won’t move, check Airplane mode: Settings > Network & Internet > Airplane mode—make sure it’s off. On some laptops, a physical switch or function key (often Fn+F2 or similar) controls the radio.
  3. Restart the device: Right-click the adapter and choose Disable device, wait a few seconds, then right-click again and choose Enable device. This forces Windows to reload the driver.

If the adapter still shows greyed out, move on to driver-level fixes.

Update or Reinstall the Bluetooth Driver

A corrupted or outdated driver is the most common cause of a greyed-out adapter. Here’s how to fix it:

  1. In Device Manager, right-click the Bluetooth adapter and select Update driver.
  2. Choose Search automatically for drivers. Windows will search online and install a newer version if available.
  3. If that doesn’t help, right-click the adapter and select Uninstall device. Check the box “Delete the driver software for this device” if it appears, then click Uninstall.
  4. Restart your PC. Windows will re-detect the hardware and install a fresh driver automatically.

If Windows doesn’t reinstall the driver, download the latest driver from your laptop or motherboard manufacturer’s support site. Match the exact model and Windows version (e.g., Windows 11 64-bit). Avoid third-party driver updater tools—they often install wrong or outdated drivers.

Check BIOS/UEFI and Hardware Switches

Sometimes the Bluetooth radio is disabled at the firmware level, which makes Device Manager grey out the adapter. To check:

  1. Restart your PC and press the key to enter BIOS/UEFI (usually Del, F2, or F10—the key appears on the first screen).
  2. Look for a setting called Wireless, Bluetooth, or Onboard Devices. Make sure Bluetooth is set to Enabled.
  3. Save changes and exit (usually F10).

On many laptops, there’s also a physical switch or a function-key combo (like Fn+F2) that toggles the wireless radio. If you have such a switch, make sure it’s in the “on” position.

Run the Windows Bluetooth Troubleshooter

Windows includes a built-in troubleshooter that can automatically detect and fix common Bluetooth issues. To run it:

  1. Open Settings > System > Troubleshoot > Other troubleshooters (Windows 11) or Settings > Update & Security > Troubleshoot (Windows 10).
  2. Find Bluetooth and click Run.
  3. Follow the on-screen instructions. The troubleshooter may reset the Bluetooth service or change power management settings.

This is a good middle step—it often fixes the problem without requiring manual driver work.

Power Management and Hidden Devices

Two less obvious culprits can cause a greyed-out adapter:

  • Power saving settings: Windows may turn off the Bluetooth adapter to save power. In Device Manager, right-click the adapter, select Properties, go to the Power Management tab, and uncheck “Allow the computer to turn off this device to save power.”
  • Hidden devices: If the adapter isn’t listed at all, it might be hidden. In Device Manager, click View > Show hidden devices. Then look under “Bluetooth” or “Network adapters.” If you see a greyed-out device, right-click and enable it.

Also, check if the Bluetooth Support Service is running. Press Win+R, type services.msc, and press Enter. Find Bluetooth Support Service, right-click it, and select Restart. If it’s not running, set its startup type to Automatic and start it.

When to Suspect a Hardware Problem

If you’ve tried all the software fixes and the adapter is still greyed out, the Bluetooth hardware may be faulty or disconnected. On a laptop, this could be a loose internal connection or a dead module. On a desktop, if you’re using a USB Bluetooth dongle, try plugging it into a different USB port. If the dongle is removable, test it on another computer—if it works there, the issue is your PC’s configuration; if it doesn’t, the dongle is likely defective.

Another option is to use an external USB Bluetooth adapter as a replacement. They are inexpensive and require no special setup—just plug it in and Windows will install the driver automatically. This bypasses the internal adapter entirely.

Frequently Asked Questions

Why is Bluetooth greyed out but the toggle is on?

This usually means the driver is disabled in Device Manager or the adapter is not properly recognized. Try uninstalling the adapter and restarting your PC to force a fresh driver install.

Can I force-enable a greyed-out Bluetooth adapter?

Yes, in most cases. Right-click the adapter in Device Manager and select Enable device. If that option is greyed out, you may need to update the driver or check BIOS settings. There’s no safe “force” beyond that—editing registry values is risky and rarely helps.

Will updating Windows fix a greyed-out Bluetooth?

Sometimes. Windows updates often include driver updates for Bluetooth adapters. Go to Settings > Windows Update and check for updates. If a Bluetooth driver update is included, it may resolve the issue.

Why does Bluetooth disappear from Device Manager entirely?

This is different from being greyed out. If the adapter is missing, it could be disabled in BIOS, the driver is completely uninstalled, or the hardware is not detected. Check BIOS settings, then try scanning for hardware changes in Device Manager (Action > Scan for hardware changes).

Is it safe to delete the Bluetooth driver?

Yes, uninstalling the driver is safe—Windows will reinstall it on the next restart. This is a standard troubleshooting step and won’t damage your hardware or data.
