I just bout a Hp Pen (microsoft) and I am not able to connect it to my laptop, which is a hp spectre x360 convertible 13, the Hewlett-Packard addition. Then pen that I have has two buttons on the side and no buttons on the eraser end with no llights. I would like some direction on wheather or not this is a compatible pen to this computer ( which I hope is) and if so then how do I connect it. Then pen is this one found here ( https://support.hp.com/us-en/document/c05166879 ) labeled as the 1MR94AA. Please Help!
