Hi @Rissa2,
Thank you for visiting the HP Forums! A great place where you can find solutions for your issues with help from the community! I came across your post and wanted to assist you.
As I understand you want to know if the HP Active Stylus Compatible with HP Pavilion x360 notebook,
No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution:
As you suggested, I did go through the Maintenance and Service guide for your PC and did not find any information about the support for Active stylus, nor there is one mentioned in the compatibility list.
That said, you can always get a passive stylus as it works on any touchscreen device regardless of its brand or model,
For more assistance, please follow this link: HP PCs - Touchscreen Compatibility with Pen and Stylus
Keep me posted,
If the information I've provided was helpful,
Give us some reinforcement by clicking the solution and kudos buttons,
That'll help us and others see that we've got the answers!
Good Luck.
