For a 4-pole combo jack to work you need:
1. To be sure the laptop's socket supports 4 poles (is there a headset
icon next to it?); and
2. To be sure your headset uses the same standard as the laptop.
Unfortunately there are at least two different and incompatible
standards for 4-poles ("TRRS"):

I can't find any detailed specs or photos of that laptop. If you are
sure there's a headset icon next to the port then my next suggestion
would be to try a different type of headset (a PC headset instead of
Apple, or vice versa).
