How to get earpods working with my hp laptop?

Earpods came with my iPhone 5, and I was wondering how I could get them to work on skype to hear regular audio, skype audio, and to use as a mic? I have 2 ports that are for headphones and one for microphones. My sister has a lenovo windows 8 computer, and she only has one port for any audio device, and earpods work on her computer.

You can't have them both working if you have different ports for Mic and Speakers in your laptop. For making one of them work, connect the jack to appropriate port and set it as default playback/recording device by right-clicking the speaker icon in system tray (bottom right corner)

Where are you plugging them again?
