Answer 1. Install/Update Bluetooth drivers Refer to the instructions below to make sure that the system has all Bluetooth/audio 2. Turn on the Bluetooth Click on the Action Center located in the lower right corner and select the Bluetooth button to 3. Pair the Bluetooth devices
disconnect power (turn off, remove plug) press the power on button on your computer (to ensure the power is drained to on-board capacitors etc) - at least 10 seconds. reconnect power. startup. For me, this reliably restores the Bluetooth device and Windows can then turn Bluetooth on/off and the device appears in Device Manager.
