Hello there. The next two pavilion models are listed under our tested devices that work with this Stylus:
HP Pavilion x360 14-ba000
HP Pavilion x360 15-br000
If these are not the model you have, then know that this product works with 2-in-1 Windows devices that have built-in inside their hardware either Wacom Active ES protocol (AES) or Microsoft Pen Protocol (MPP). If you are not sure if yours has one of these technologies built-in, you can reach out to the manufacturer of your device to confirm this. Hope that helps! Best
