Bluetooth device shows "Code 39" error in Device Manager on Windows 10 laptop

I'm encountering an issue with my Bluetooth device on my Windows 10 laptop. In Device Manager, the Bluetooth device is displaying an error message: "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)".

Here are some additional details about the problem:

• My laptop model is HP R007tx, and it is Bluetooth-capable.
  
• Despite the Bluetooth hardware being present, the device manager shows this error, indicating a problem with the device driver.
  
• When attempting to troubleshoot, I found that the Bluetooth driver's digital signature cannot be verified, suggesting a revoked signing certificate.
  

I've already tried the following troubleshooting steps without success:

• Reinstalling Bluetooth drivers obtained from the HP support website.
  
• Updating Windows and checking for driver updates.
  
• Restarting the laptop multiple times.
  
• Checking for dependencies and performing a System File Checker scan.
  

Despite these efforts, the error persists, and I'm unable to use Bluetooth functionality on my laptop.

Can anyone provide guidance on how to resolve the "Code 39" error with the Bluetooth device driver? Is there a way to address the issue with the driver's digital signature or any other troubleshooting steps I can try?

Your assistance would be greatly appreciated. Thank you!

Laptop details:

• Make and model: HP R007tx
  
• Operating system: Windows 10
  
• Bluetooth device error: "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)"
  

 

Error Code12 for Synaptics SMBus driver in Device Manager

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you receive, “This device cannot find enough free resources that it can use. (Code 12)” error for Synaptics SMBus Driver in Device Manager. I’ll help you with this issue.



However, please let us know:

• Are you aware of any changes made to the computer recently?
  
• Which build version of Windows 10 is installed on the computer currently? To check type:
  winver in search bar on the Taskbar and hit
  Enter.
  
• What is the make and model of the computer?
  

The error (Code 12) can occur if two devices that are installed on your computer have been assigned the same I/O ports, the same interrupt, or the same Direct Memory Access channel (either by the BIOS, the operating system, or both). This error message
can also appear if the BIOS did not allocate enough resources to the device.



As you have already tried removing, uninstalling and updating the driver, I would suggest you to try checking for any hidden devices, remove them and check if that helps. Refer the steps mentioned below:



Before proceeding with the steps, I suggest you to
Create a system restore point.

1. Press Windows Logo key + X, and select
   Device Manager.
   
2. Click on View and select
   Show hidden devices.
   
3. Expand Mouse and check if there is any
   hidden device.
   
4. If there is any hidden device, right click on it and select
   Uninstall device.
   

You can also try removing Motherboard resources from Device Manager, and check if that helps. Refer the steps mentioned below:

1. Press Windows Logo key + X, and select
   Device Manager.
   
2. Click on View and select
   Show hidden devices.
   
3. Expand System Devices, locate Motherboard resources devices, right click on each of them and select Uninstall Device.
   
   Note: If you can’t locate them, try with “PCI standard PCI-to-PCI bridge” or simply uninstall “PCI Bus”.
   
4. Your PC might freeze after uninstalling the devices, at this moment, hold the power button of your PC to switch off the computer and then switch it on.
