Microsoft Windows 10 (64-bit)

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 ProBook 4540s 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?

What model Wi-Fi adapter does your notebook have?

 

If you don't know, go to the device manager, click to expand the Network Adapters device manager category and there you will find the name and model number of the wireless network adapter.
