Good afternoon and welcome to the community.
I believe that you'll need an adapter similar to this: http://www.everbatim.net/store/index.php/headphone-microphone-jack-splitter.html in order to use the combo input jack on your laptop.
I've not used the linked device, personally, and have never dealt with the company, either. I provided the link only as an illustration, so please reseach any purchase.
Hope this helps.
