If he's willing to throw $3.50 at the problem (and wait a couple of weeks for shipping from China), have him try a set of ferrite cores. You clasp one of these around the mic cord near the point where it plugs into the computer, and it can block out a lot of RF interference.
> I think using a USB cord with a ferrite core for my phone will reduce that buzz.
It's what they are designed to do and they are cheap enough that it's worth a shot. You would add one to the end of the cable that plugs into the PC.
Way cool! Thank you. I couldn't figure out the proper name for them. I just ordered some off of amazon ;) Link.
Maybe looping the wire around a ferrite bead may help?
amazon? ebay?

I'm not sure this will solve it 100% but it's worth a try. If not return it or go to a shop near you and ask for this and if its possible to test it out and return it.
Sounds like RF noise from the 19V converter getting into 12V power. Maybe buy something like this for both the power leads to your laptop and the camera.
I think you are going to have to make your own. Here's some links from a comment I made from a year or two ago:
Hey! Here is a guide that will tell you everything you need to do and it doesn't require any electronics knowledge at all: http://www.stepmania.com/forums/input-adapters-and-controllers/show/5493
I made two of these and they work great. With the pinout, you're pretty much set.
The only thing that I needed to purchase that the guide was not 100% on were ferrite cores - I recommend you getting these. They are little cylindrical clasps you put on to wires that help with interference. All parts linked below:

Expensive? Not sure if the diameter matches, but here’s a pack of 5.
is it an HDMI monitor? If you have audio cables you can try clipping a ferrite bead on it.
If you get a lot of buzzing and there's no interference than it's mostly likely a failing speaker.
Use a USB extension cable, like this, and clip a ferrite choke on each end. Route the USB such that it doesn't cross, or ideally, come anywhere near any power cords or transformers, and place the dongle as far away from the PC as you can.
It'll help a bit, but it's still a $15 piece of hardware, and as such, won't be perfect.
You should get some ferrite cores. Put one on each end of the cables (your charger and your audio cable).
It's most likely engine noise entering the charging cable, but it could also get picked up by the audio cable.
You can try different schemes. It may be placebo, but I think they do best when they have one wrap around the core, like shown here.
