Windows 10: Bluetooth Hardware not devices not found after update 1/12/2020

My computer updated on 1/12/2020, before this my bluetooth was working perfectly, afterwards my bluetooth hardware built-in was no longer found on my device. I'm not referring to bluetooth devices like mouse, conroller, etc. either.


Checking device manager with "show hidden files" on does not show any bluetooth options nor is bluetooth adapter under any category. Services manager still has bluetooth support services automatic and running; restarted for good measure.


Should probably mention my PC is a laptop with Intel I7-7700HQ CPU; Network Card is Intel Dual Band Wireless-AC 3168.

Bluetooth devices will not connect

Hello Jean57sn, my name is Irisdiel and I am an independent advisor.

Down below I'm going to provide you with steps and instructions on how to help you with your issue which was listed by Lenovo Support to best help you.

Make sure your computer has the necessary hardware and that wireless is turned on. Bluetooth requires both hardware and software to work. Not all wireless networking hardware supports Bluetooth.

Method 1:

Step 1: Enable Bluetooth radio If Bluetooth is not turned on it may not show up in your control panel or device manager. We first need to enable the Bluetooth radio Press the key or button to enable your wireless adapter. This key may be the, F8 or Press Fn+F5
(or F5).

Step 2: Check the Bluetooth drivers

Click Start and search for "Device Manager"

Look for all Bluetooth listings by opening the Network Adapters category and the Bluetooth Radios category (if available). If you can't find any Bluetooth listings under Network adapter and Bluetooth radios proceed to next step B

Make sure the driver has no Yellow exclamation mark or Down arrow sign

- Yellow Mark = The Bluetooth hardware is not responding or set up correctly. Updating or reinstalling Bluetooth drivers may correct this problem

- Down Arrow= Bluetooth is disabled. Right-click the device and select Enable to turn on Bluetooth.

Method 2: Enable Discovery Mode

Click Start and search for "Change Bluetooth"

From the Options tab, select Allow Bluetooth device to find this computer, and make sure Allow Bluetooth devices to connect to this computer is selected.

Click OK and try to connect to your device. If problems persist, continue to the next step.

Method 3: Update Bluetooth Drivers

Click Start and type "Device Manager"

In Device Manager locate the Bluetooth adapter. Right-click and select Update Driver Software,

Select Search automatically for updated driver software, and then follow the rest of the steps.

Then...

Click Start and type "Device Manager"

In Device Manager locate the Bluetooth adapter. Select Uninstall

Restart your machine and Windows will automatically install the driver after you logged in

I also suggest you refer to Lenovo support down below as this issue has to do with Microsoft for best support:

Cannot use bluetooth device

1 Pairing is done in Settings, Devices
1.1 You click on Add Bluetooth or other device
1.2 You choose Bluetooth
1.3 If there is a pairing button on the bluetooth device itself then you press that now. You need to check the instructions for your bluetooth device to see how to do this - several automatically go into pairing mode when they switch on, others have a button that needs to be pressed for, say, 5 seconds.
1.4 The computer detects all available bluetooth devices and you select yours from the list. If yours is not on the list then Windows could not detect it.
1.5 It connects - pairing includes connecting
1.6 The computer sounds a buzz in the earpiece then displays Your device is ready to go and you click on Done
1.7 The device is shown in the devices list below the subheading Audio and it shows it as connected
1.8 The device should also appear in Control panel, Sounds, Playback tab
1.9 The device should also appear in Control panel, Devices & printers
1.10 {I just paired some bluetooth earphones as I typed so I could make sure these notes were correct} You use a music player and the sound comes out of the bluetooth earphones

2 If this is not happening for you then go to Contol panel, Devices & printers
2.1 Right-click on the device & select Remove device
2.2 You can now try pairing from scratch again
2.3 Several other users have reported that only removing the device with Bluetooth command line tools - BluetoothInstaller allowed them to re-pair again [see xzion's guidance below]
2.4 Yet others reported that only the KeithM code or Bungee's guidance worked for them [see below]

3 Where is this all going wrong for you?
[I assume we are definitely talking about bluetooth headphones/earphones. I understand that WiFi ones do also exist.]

Several people registered in TenForums just to be able to thanks xzion, KeithM & Bungee. Apparently, what worked for some people did not work for others so each solution seems worth trying.

Bluetooth disappeared after update

I just installed the 2020-02 and 2020-03 cumulative updates. Windows seems now to have forgotten about bluetooth. I've gone through steps listed to diagnose this, but most notably, I no longer have a switch to turn bluetooth on and the troubleshooter says
I have no bluetooth capability. In the device manager, bluetooth is hidden. Scanning for hardware changes does nothing. It says I have 2006 drivers, "the most up to date". (Really?).

Has anyone figured this out?
