Webcam won’t display in Windows or Linux, only appears after device has been on for long period

[ShortFormErnie]

My webcam appears to have a hardware issue that is preventing me from using my webcam normally. It does not appear on boot and may eventually appear, but only after a lengthy handshake process with the computer that sees frequent disconnects. Some logs, which show that the computer does not properly interact with the internal camera for more than an hour after boot:

I can confirm this is not unique to Linux, as the camera does not appear in Windows 11, either, nor in the BIOS. I have a feeling it may be related to a frayed cable or damaged part inside the device, but there appears to be no way to test this inside the BIOS diagnostics, so I’m kind of at a loss. I’m capable of taking apart the computer and replacing parts, but I just need a little help determining what I need to take out and replace. Am I looking at a screen replacement, or something less dramatic?

Hi  @ShortFormErnie,
 
Welcome to the HP Support Community!

Thanks for reaching out!

I understand how this must be for you especially since the webcam isn’t showing up consistently across Linux, Windows, or even BIOS. Thank you for sharing those detailed logs;   From what you’ve described, it does sound like the internal camera may have a hardware-level issue, possibly a loose or damaged cable connection inside the display assembly.

Could you kindly confirm the exact HP laptop model you’re using? 
Also kindly confirm the below details :  

When the camera does eventually appear, does it function normally  or does it still disconnect intermittently?

Does the camera ever show up in Device Manager (Windows) or lsusb (Linux) immediately after boot, or only after those long delays?

In the meantime, here are few steps you can try before considering a hardware replacement:

BIOS reset – Enter BIOS setup and restore defaults. 

Check Device Manager (Windows) – Look under “Imaging Devices” or “Cameras.” If it appears with a yellow warning icon, uninstall the device and restart.

Depending on your model, the fix could be as simple as reseating or replacing the webcam module and cable, or it might require a full display assembly replacement if the cable is integrated. 

I hope this helps.

The exact product is mentioned in the original post:

> Product: HP ENVY 16 inch Laptop PC 16-h0000 (534C7AV)

I can confirm that the camera does function normally after some time but there may be some visual artifacts that might appear as it’s loading in. I test the app with cameractrls, a Linux app. I can also confirm that an external camera works fine. I did all the BIOS updates. I will test the device manager in Windows next.

When I dug in there, I did see that the cables coming out of the monitor on the left side (shown at this point in the disassembly video) appeared to have been partly unbundled from the tape and it looked like at least one cable might have some wear, though I didn’t see it breaking through. (Would some Kapton tape help in this situation?)

I have gotten in here in the past, notably to replace the trackpad and battery, upgrade the RAM, and install a new SSD. So I would be comfortable replacing the monitor. When I bought the device (refurbished, about three years ago) it came with dents on the top display so I’m not opposed to swapping out the entire screen if I can find the right deal on eBay. The device is out of warranty.

Thanks for your insights.

[ShortFormErnie]

In Device Manager on Windows I got a message similar to the one I received when I ran `sudo dmesg -w | grep -i -E "usb|uvc"` on Linux:

This suggests that it can detect the device, but when it talks to it it sends back garbage or at least an incomplete message.

Hi @ShortFormErnie,

Thanks for sharing all those details. 

Since you’ve confirmed the webcam issue happens on Linux as well as Windows and BIOS, this isn’t an OS‑specific bug; it's pointing to a hardware‑level fault. 

That said, if you’d like to explore Linux‑specific troubleshooting and community expertise, I’d recommend reaching out to some of the active Linux support communities where HP users and developers often share fixes.

And if you’d prefer a professional inspection, you can also visit an HP service center. They’ll be able to reseat or replace the webcam module or display assembly safely.

You can locate the nearest HP service center using our Service Center Locator:​
