I can't find the mic on my HP G60-230US Notebook.Where is it?

I believe it's the dot just right of the webcam. The microphones in current laptops are very small...small enough that they might not even be labeled. I'm not positive this is right.

P.S. There's also a microphone port on the front of the laptop, but I don't think that you're asking for that.

As is with most laptops these days, the microphone is most likely at the top, center of your screen; right beside your camera (if you should have one). The reason you may not be able to see it is because it is most likely just a small hole that you wouldn't notice without looking. I hope this answers your question! Best of luck!
