How to connect x32 turtle beach headset to a laptop using headset jack?

I'm looking at getting a new computer than I can play video games decently on but the two that I'm looking at (Lenovo Y40 or the Lenovo ThinkPad T450) only have a headphone/mic jack. I'm getting very frustrated on how to connect my X32 turtle beach headphones to a newer laptop because the adapter requires you to connect one cable into a headphone jack and one into a microphone (due to wanting to be able to chat as well) Also, wondering if I wouldn't even need to get a new cable and just use the cables that come with the headphones? Please Help!

Added (1). I'm looking at getting the Lenovo Y40 or the Lenovo ThinkPad T450s. Just wanted to restate that.

You have 3 options:
1>Keep looking, you might come across a new laptop with separate headphone and microphone sockets.
2>Dump the headset. Sell it on ebay and purchase a new headset with a combo plug
3>Purchase a USB sound card for the laptop, this will have many sockets to connect even 7.1 theater speakers.

I haven't seen "separate to combo" adapters for headsets, but one might exist, someone else might give you an answer, keep this question open.
