How to fix my bluetooth , it doesn't work or show anymore

Fully shut down the Windows 11 PC while holding Shift, wait one minute, and then power it back on to reset Bluetooth hardware that has stopped responding.

1. Perform a complete shutdown

A normal restart may not completely reset the Bluetooth adapter.

1. Hold Shift.
2. While holding it, select Start → Power → Shut down.
3. After the PC turns off, wait one minute.
4. Turn it on and check Settings → Bluetooth & devices.

This is Microsoft’s first procedure when the Bluetooth icon or switch has disappeared or is grayed out.^1^

If this is a laptop, also check whether it has a physical wireless/Bluetooth switch or keyboard function key and ensure it is enabled.^2^

2. Run the Windows 11 Bluetooth troubleshooter

1. Open Start → Settings → System → Troubleshoot → Other troubleshooters.
2. Find Bluetooth and select Run.
3. Apply any suggested repair, then check whether the Bluetooth switch has returned.

Also press Windows+A and verify that Airplane mode is off.^1^

3. Check whether Windows detects the adapter

Right-click Start → Device Manager, then use the matching case below.

If Bluetooth appears

1. Expand Bluetooth.
2. Right-click the Bluetooth adapter—its name may contain “Bluetooth” or “Radio.”
3. Select Update driver → Search automatically for drivers.
4. Install any update and restart if prompted.

If updating does not restore the missing control:

1. Right-click the adapter and select Uninstall device → Uninstall.
2. Select Start → Power → Shut down.
3. Turn the PC back on. Windows should attempt to reinstall the adapter.
4. If it does not, return to Device Manager and select Action → Scan for hardware changes.^2^

If Bluetooth does not appear

1. Look under Other devices for an unidentified Bluetooth or wireless adapter.
2. Visit the support site for the exact PC or motherboard model.
3. Download and install its Windows 11 Bluetooth/wireless driver.
4. Restart the PC and check Device Manager again.

If the adapter remains completely absent after installing the manufacturer’s driver, contact the PC manufacturer. Microsoft notes that a disappeared Bluetooth switch can indicate a Bluetooth hardware, driver, or firmware error.^1^

4. Install optional driver or firmware updates

Open Settings → Windows Update → Advanced options → Optional updates, install applicable Bluetooth, driver, or firmware updates, and restart.

If the manufacturer offers a BIOS or UEFI update, use only the update for the exact PC or motherboard model. Connect the computer to reliable AC power, follow the manufacturer’s instructions, and never interrupt or power it off during the update, because a failed firmware update can leave the PC unable to start.
