Dell XPS 15 L502x Webcam

Hello everyone,

I am aware of an ongoing issue with the webcam for the Dell XPS L502x models. Usually if the webcam malfunctions, a power cycle will typically do the trick to get the webcam to function. However, my issue is software/driver related.

One day, I left my laptop sitting on my desk, and Windows decides to install it's own generic webcam driver. By the time I got back the Windows generic driver was installed, not the Dell Quanta h.264 driver. Thus, I updated the driver to use the original driver. In the device manager, it states that the driver is working fine, but whenever I use Skype or Dell Webcam Central, it says there is a program that is using the webcam thus it cannot function. I doubled check for any processes and also use a program named "Process Explorer" and found nothing.

I also ran Malwarebytes, CCleaner to make sure there were no suspicious activity going and found nothing.



If anyone knows if there is a solution, that would be great.

After many years of my webcam not working, I got my webcam to work again by replacing the webcam module with a replacement I got from eBay. Everything is working as it is before.

In summary, buy a OEM replacement of the Dell L502x webcam.

I just performed the instructed steps, and it's weird even after uninstalling the driver, and restarting Windows automatically installs a generic driver. I therefore must update it to switch it over the Dell Quanta and I still experience the same issue.

Hi mega99999,
