HP Active Pen Problems...

[SgtBot]

I recently got a used pavilion x360 convertible laptop (14m-ba015dx) from my local bestbuy, and everything ran very smoothly except for the active pen that came with it. The pen is an SPEN-HP-001 (905512-001). From what I could gather from the support tickets I read it was a problem with the drivers, so I updated all of the hp drivers and then did a clean install of the hp pen control program and the touchscreen driver, and then I updated the BIOS as well. I bought brand new batteries for the pen, and still no luck. The instructions for the pen said to just put the battery in and touch the screen to use it, and I've tried looking for ways to pair it otherwise but no luck. The wonderful HP employees just tell everybody to check compatibility lists for the pens, but I checked and mine was on there it just isn't working. Am I missing something or is this active pen just broken? I feel like BestBuy would have made sure the pen worked before selling it...
