The screenshots show the Bluetooth adapter is not currently detected by Windows (Code 45). When that happens, the Bluetooth toggle and taskbar icon can disappear.
Try these steps in order:
- Fully power off the PC, then turn it back on
- Hold Shift.
- Select Start > Power > Shut down.
- Wait 1 minute.
- Turn the PC back on.
- This is important because Shut down, not Restart, completely powers off the Bluetooth hardware.
- Check Airplane mode
- Press Windows + A to open Quick settings.
- Make sure Airplane mode is Off.
- Run the Bluetooth troubleshooter
- Open Settings.
- Go to System > Troubleshoot > Other troubleshooters.
- Find Bluetooth and select Run.
- Update the Bluetooth driver
- Right-click Start > Device Manager.
- Expand Bluetooth.
- Right-click the Bluetooth adapter and select Update driver.
- Select Search automatically for drivers.
- Restart the PC if prompted.
- If the adapter still appears in Device Manager but Bluetooth is still missing, uninstall and let Windows reinstall it
- In Device Manager, expand Bluetooth.
- Right-click the Bluetooth adapter and select Uninstall device.
- Shut down the PC.
- Turn it back on so Windows can try to reinstall the driver automatically.
- If Windows does not reinstall it, scan for hardware changes in Device Manager.
- Install optional updates
- Go to Settings > Windows Update > Advanced options > Optional updates.
- Install any available optional updates.
- Restart the PC.
- Install the latest Bluetooth, BIOS, or firmware updates from ASUS
- Bluetooth hardware errors are often caused by the PC manufacturer’s drivers or firmware.
- Since the device shown is an ASUS Vivobook, check ASUS support for the latest Bluetooth driver and any BIOS/firmware updates for that model.
If the Bluetooth setting is still missing after these steps, Windows may still not be detecting the Bluetooth hardware. In that case, manufacturer-specific troubleshooting is the recommended path.
