Hello -

My husband gave me this laptop (GT72 2QD), because he got a full-sized desktop, and I'm trying to get some stuff working he didn't think was important. First it was the keyboard lights, now I'm working on the webcam. 

The webcam is not showing in Device Manager, and even if I choose to show hidden devices, there is nothing under "unknown" and there is no imaging or camera category. I first installed the SCM and made sure that the webcam was "on", but no luck. I also tried toggling the button through SCM, no luck. I tried using the Fn+F6 keys, but no luck. I've updated the chipset, no luck. When I look up the specifications for the laptop, it just says "webcam", there's no model or device identifier that I can go off of. I was going to ask MSI for support, but I also can't seem to register the laptop successfully. I'm thinking because my husband might have registered it?

Running Windows 10 (1909 - 18363.815), there are no pending updates that I can tell. 

TIA

Try pressing the Fn and F5 keys together or if you look at your F-keys there should be one with a camera graphic if it's not F5.

Thanks for the assist, but the key combo on my keyboard is Fn+F6 (I can see the webcam icon), and I already tried toggling that on and off. I've also heard that it wont appear in Device Manager until its "on" (using Fn+F6 or SCM) but I've tried using those options and confirming in Device Manager with no luck. F5 is Eco mode for the battery.

That's not the case.  As soon as the webcam is enabled it will show in device manager as long as the drivers are installed.  If they are not installed it would appear as an unknown device.
Camera is not in use but still shows up after being enabled in the picture.  And if it's not enabled it will still be visible in device manager by showing hidden devices if it's installed and functioning properly.

Well that's nice to know! I do computer / software repair all day long and when I read that online it seemed fishy - but I've never had an MSI laptop so I thought... Okay... 

I just don't know where to get the drivers!

Do you see any unknown devices listed?  I think Windows uses generic webcam drivers so can try doing a windows update and see if that may pick something up that was missed.   If you see any unknown devices in device manager you can go into the properties, click on the details tab and check the hardware id's from the properties drop down box.  Then go to a pci database type site and put in the id's to see if you can find the manufacture and get them directly from them since MSI doesn't seem to provide any for your model.  It is also possible that it does not work or function properly therefor windows won't pick it up no matter what you do.

You can also try this after pressing Fn+F6. Go into device manager and right click on your computer name and scan for hardware changes.  See if that picks it up.

No offense taken! I appreciate any tips, because I've been pulling out my hair. I work primarily with Dell (Enterprise environment) and their support portal let's you just drop in a service tag and shows you everything you need. I'm finding it hard to find the equivalent on the MSI support portal. I've been working off of this page: https://www.msi.com/Laptop/support/GT72-2QD-Dominator-4.html

I had one unknown device earlier, but it was for the keyboard (installed the SteelSeries 3 and that fixed the keyboard). But nothing that is showing as an error or unknown. Going to force some more update checks, see if I'm missing anything.

One other thing you could possibly try is to reset the ec.   It's possible that the embedded controller just stopped communicating with the webcam.

I've never had to do this myself so not sure if it will work or not but I found the instructions here:
