Bluetooth stops working on the Dell Inspiron 14 5445 after a Windows 11 update, or the adapter disappears from Device Manager entirely. The AMD Ryzen 5 7530U platform uses a shared Wi-Fi and Bluetooth chip, making it sensitive to driver and power management changes.

- Expand the Bluetooth section
- Right-click the adapter → Uninstall device
- Check “Delete the driver software for this device”
- Restart — Windows reinstalls a working driver automatically

Windows can power down the Bluetooth adapter to save energy. Open Device Manager, double-click the Bluetooth adapter, go to the Power Management tab, and uncheck “Allow the computer to turn off this device to save power.” Click OK and restart.

Settings → System → Troubleshoot → Other troubleshooters → Bluetooth → Run. Apply all suggested fixes and restart.
