Lenovo W520 - no microphone jack

I recently purchased a new thinkpad W520 laptop and was trying to plug in my headset with built in microphone for using skype. My old thinkpad T500 had two audio jacks, one for headphones/speakers and one for a microphone, right on the front. My headset also has 2 3.5 mm jacks. The new W520 only has a single audio jack with a picture of a headset with microphone above it. How can I plug my headset in? Do I need a different type of headset, or is there some kind of joining adapter I can get that will allow me to plug in a my dual jack headset to the laptop?


Will this do what I need or is this only for combining two audio signals of the same type (i.e. 2 input or 2 output, not one input and one output)
