The Lenovo Yoga 7 2-in-1 14AGP11 can use ANY stylus using AES drivers.
This is mostly meant to fill a gap of knowledge I found while doing Research.
For context, I bought a Yoga 7 2-in-1 14AGP11 for college and they offered to bundle it in with its included pen (Lenovo yoga pen 2) which I initially refused.
Later on I actually was interested in getting a pen, but there were none in stock in my area, plus the pen is pretty pricey at the moment due to how new it is.
This led me down a rabbit whole of finding out what alternatives I could use for my laptop.
When doing research for what Stylus work for my laptop I bought a Lenovo Active Capacity Pen because it was cheap and it was also a Lenovo stylus, so it should've worked.
When I got this pen, it worked on the laptop surprisingly. The only issue was that it was extremely buggy, it would draw lines all over the screen, It would sometimes just not draw at all, and it was very inconsistent. But, the pen was recognized by the laptop, and it even appeared within the Lenovo pen app.
Although I got a "working" pen I wanted something that was actually better. So I did some research using AI. I had them find what other pens would be compatible with my Laptop. Come to find out, Gemini, Copilot and ChatGPT didn't think any other pen Besides the Lenovo Yoga Pen 2 would be compatible with my Lenovo Yoga. Copilot didn't believe any other pen could work, Chat was unsure, and Gemini just said "maybe". I did my own research using Lenovo's website and Q&A section. They were pretty old and outdated with nothing useful.
After some time, I compared Stylus's within the Lenovo website and none of them said they worked on a single platform so I gambled and got myself a Lenovo Digital Pen 3.
Come to find out after the purchase, this pen was mostly designed for the tablets Lenovo makes, and it would be a gamble if it even worked on my Lenovo Yoga.
When I finally got the pen, it worked perfectly fine, with no issues at all.
This is because of the Pen Drivers that Lenovo has for the Lenovo Yoga.
As long as the pen uses AES drivers, it will work, and be recognized by the laptop, while it may not be perfect, it will get the job done for the most part.
So if you are wanting to know if a Stylus will work on your laptop, I recommend checking if you have drivers installed for a Stylus. Ensure your laptop has touchscreen and the capability for Universal Stylus Initiative (USI) Drivers, Wacom WinTab Drivers, Wacom AES (Active Electrostatic) Drivers, (Which is what Lenovo uses), Microsoft Pen Protocol (MPP) / N-Trig Drivers and Windows Ink API.
