Mic and Camera issue

My laptop fell recently, and a few days later both the microphone and camera stopped working. I consulted some technicians, and they mentioned that a cable might have become loose or disconnected, since there’s a cable running from the mainboard to the screen that also connects to the mic and camera. Is that correct? Should I open the screen to check it?

Hi @mohammedhitari!

The technicians may not be wrong. As far as I know, that's the most common error because camera and microphone are in the top bezel and therefore connected via the same cable.

This is actually a known issue with the XPS 13 Plus 9320. Multiple users report the camera and microphone failing simultaneously, especially after drops or physical impacts. According to repair shops, it's a "familiar thing with these laptops" and is related to the internal cable connection between the motherboard and the screen.

The display cable that runs through the hinge carries:

Display signal
Webcam/camera connection
Microphone connection
Sometimes touch digitizer (if applicable)

When a laptop falls or the hinge gets stressed, this cable can become loose or damaged, causing both camera and mic to stop working simultaneously.

I would recommend opening the screen ONLY if:

You checked that there's no software error first:
- Check Device Manager - do the camera and mic show up at all?
- Try reinstalling Intel 2D Imaging MCU Visual Sensing Controller Driver
- Update all drivers from Dell's support site for your specific model
- Check BIOS settings - sometimes camera/mic are disabled there
If software checks fail, then it's likely the cable:
- The display cable (LVDS/eDP cable) needs to be reseated or replaced
- This requires opening the screen bezel and potentially the bottom case
- It's a delicate repair - if you're not comfortable, consider a repair shop

Given that your laptop fell recently and both devices failed together, it's almost certainly a loose or damaged display cable. The good news is that reseating it might fix the issue without needing a replacement part!

Best of luck with the repair!

Best wishes

Marvin

My Dell camera failed a few months before the screen started flashing and then completely failing. The ribbon cable fails for the camera connection first and migrates to the other circuits such as the monitor under fatigue wear. So much for the pricier XPS brand. Mine didn’t make it 3 years - and there were no drops or incidents.

I opened the screen and connections were fine. The cable reliability is very poor.
