HP EliteBook 840 G9 - Integrated Camera Issues
Asked by
TechyTraveler42
I'm a service desk analyst and I've encountered a recurring problem with the integrated camera on several HP EliteBook 840 G9 laptops running Windows 11 (24H2). The webcam is completely unrecognized: the camera app, Teams, and Zoom all show that no camera is detected, and Device Manager has no camera listed. The HP Camera app is also greyed out. After running a command to check for camera devices, it returned nothing. From my digging, I found that the laptop uses Intel's IPU6, which doesn't seem to be enumerating correctly, meaning the camera won't function in Windows. I've double-checked settings in the BIOS, reset it, used the HP Support Assistant, reinstalled drivers, and ensured privacy settings are correct, but nothing has worked. I'm considering wiping the device entirely, so any advice would be appreciated!

Make sure you’ve checked any keys or buttons that might disable the camera. Sometimes there’s just a physical switch or software setting that could be turning it off.

I've seen this before—doing a proper power reset usually resolves the issue. Here's a quick guide: shut down your laptop completely (not hibernation), unplug everything, hold down the power button for 30 seconds, then plug it back in and start it up. This action resets embedded controllers and can fix various hardware detection problems.

Just a thought—if you've already tried extensive troubleshooting, wiping the device could be a viable last resort. If your setup is well-organized, re-imaging should be straightforward and could save you time in the long run.

It looks like the newer HP cameras are no longer USB-based, and they rely on the Intel IPU6. I recommend checking for any recent firmware updates for both the systemboard and peripherals. Another option is to boot the laptop using a Linux live USB to see if it detects the hardware—if not, it might be an issue with the firmware or hardware rather than Windows itself.

For the 840 G9 with IPU6 cameras, ensure your BIOS and chipset firmware are fully updated; sometimes they need specific camera firmware updates separately. It's also worth looking into group policies or security software that might block the camera. If booting from a Linux USB doesn't detect the camera, the issue might be at the firmware level. If all else fails, HP has a peripheral firmware recovery tool for IPU6 cameras, though finding it can be tricky.
