Elitebook 840 G1: replace mic-only module with webcam/mic module?

[johnnyzero2a]

Customer brought me an Elitebook 840 G1, complaining that she could never get the webcam to work.

After removing the screen bezel, I discovered the reason why: there is no webcam; this computer came equipped with the "mic-only" module. 

Am I correct in assuming that I should be able to just replace it with the correct webcam/mic combo module for this model, and that will give her a functioning webcam? Both modules appear to have the same number of pins on the cable connector.

One other complication: the screen bezel has the usual webcam port/hole at the top center (which is why the customer always assumed it had a webcam), but the port is opaque/black. See photo below. Is it possible that HP just slapped a black sticker or adhesive cover over that port on the mic-only models? I'm reluctant to try to remove it with an x-acto knife - don't wanna scratch the glass or something.

Any advice or suggestions are much appreciated.

Updates:

Yup, HP just slapped a little black adhesive disk over the bezel's webcam port on non-webcam models. I was able to carefully remove it using an x-acto knife.

Since I haven't gotten any replies, I just went ahead and ordered a webcam/mic combo module. Used ones are cheap enough. I'll install it and post the results here.

Success.

I was able to "upgrade" to a webcam by just swapping out the module.
