Compaq 6530b Notebook: Windows 10 doesn't support Bluetooth?

[Jopower]

I have a Compaq 6530b notebook that I upgraded to Win 10 (64-bit). Win 10 found all devices but the Bluetooth transceiver. It appears as "unknown device" in Device Manager. I have tried the auto-update and manual update to no avail. I have tried to use the Win 7 version Bluetooth driver sp44774.exe, but no luck. It is also difficult to determine the right BT device to find a driver for as HP doesn't give any real details in the device specs. Here's the info I have:

HP Compaq 6530b notebook PC
HP Integrated Module with Bluetooth Wireless Technology
2.0 Compliant

Software HP provides:
Broadcom Bluetooth for Windows
Microsoft Windows XP Bluetooth Software

I have also checked the Device Manager "Hardware ID" and here is the data:

ACPI\VEN_HPQ&DEV_0004
ACPI\HPQ0004
*HPQ0004

I did find this possible solution at  https://www.wiknix.com/solved-bluetooth-not-working-in-windows-10/

My Bluetooth now works perfectly on Windows 10. (Dell Inspiron 1565). This solution works 100% on Dell Laptops that have WIDCOMM Bluetooth software or Dell Wireless 365 Bluetooth Module. If you have other laptop, then I also list the other solution that solved the Bluetooth problem in Windows 10.

Solution 1: Download and Install Bluetooth Drivers
Step 1:

First of all Download your Bluetooth drivers and extract it.
Step 2:

Now go to C:\Dell\Drivers and find out your Bluetooth folder (In Dell Inspiron 1564, C:\Dell\Drivers\24T1W\R235168)
Step 3:

Now open Win64 (for 64-bit) or Win32 (for 32-bit).
Step 4:

Now find and install “BtwMM.exe“.

Step 5:

Now find "Inst.exe" and install it.
Step 6:

Now Restart your PC. Reboot is required. So open Bluetooth after restart your PC. That’s it. This solution is working for me.

Watch Video Tutorial of this Solution.
Solution 2: Update Bluetooth Drivers
Step 1:

Search “Device Manager” and open it. Now find Bluetooth and expand it.

Device Manager
Step 2:

Now right click on Bluetooth Module and click Update driver software.
Step 3:

Click “Browse my computer for driver software“.
Step 4:

Now click “let me pick from a list of device drivers on my computer“.
Step 5:
Select your Bluetooth Drivers or software and click Next. (In my case Dell Wireless 365 Bluetooth Module). You will see the driver update successful dialog box. Now Restart your PC (Required). That’s it.

I show this "solution" because I looked in the HP sp44774.exe driver files folders I previously installed and found it's using the exact same named files to install and run the device as Dell does (BtwMM.exe and Inst.exe).

Is WIDCOMM Bluetooth the real device name? (and is there a model number, etc.)

Will the Hardware ID help find the right drivers?

Is there some chance of getting it to work on Win 10?

Hi:

The driver you need for the 0004 is not for the bluetooth.

You need this driver for that device...

This package provides the HP 3D DriveGuard software for supported notebook models that are running a supported operating system. HP 3D DriveGuard protects the hard drive by "parking the heads" if the notebook is accidentally dropped or is abruptly impacted by another object.

Here's why the bluetooth radio disappeared from the device manager...this assumes your notebook came with the optional HP Bluetooth module, and you know it was working on W7...

You either had the HP wireless assistant or HP connection manager software installed at the time you upgraded from W7 to W10.

And you had the bluetooth radio turned off in either program.

Now that you upgraded to W10, neither program works on W10 (you can try the W7 versions, but I am 99% sure they won't work).

The only way you will ever get the BT to work again, is to reinstall W7, install either the HP wireless assistant or HP connection manager software, restart the PC, and use either program to turn on the bluetooth.

Once you have done that, uninstall the software, restart the PC, confirm the BT is still turned on and present, and then you can upgrade/reinstall W10.

Hi,

I own 6530b notebook and had same problems with Bluetooth when migrated from Windows 7 to Windows 10. Downgrading Windows version wasn't an option for me. 

This is what I've done:

- Download a free tool WinToUSB https://www.easyuefi.com/wintousb/index.html

- Download Windows 7 ISO image https://www.microsoft.com/en-us/software-download/windows7

- If there a problems with Microsoft download site, use these advices https://www.howtogeek.com/186775/how-to-download-windows-7-8-and-8.1-installation-media-legally/ . Personally I used  Microsoft Windows and Office ISO Download Tool .

- With WinToUSB create a bootable USB with Windows 7 (so called Windows To Go).

- Boot Windows 7 from the created USB.

- Download  HP wireless assistant https://support.hp.com/us-en/product/hp-compaq-6530b-notebook-pc/3687446/drivers and intall it.

- Run HP wireless assistant and activate Bluetooth.

- Remove USB and start Windows 10 normally.

- Enjoy Bluetooth on Windows 10.
