I know it sounds obvious but if you're unsure about your PC's model number, I'd contact HP and ask - hopefully you'll get a knowledgable response. Also, if you can find your particular model on their site and the pen is absent from the various accessories they're trying to flog for it, then yep it probably won't work with one (an active one, that is).
Good luck!
