Question about Lenovo ThinkPad Pen Pro

I also had to try it out until it worked. If the pen is not explicitly supplied with the tablet, I always recommend asking the manufacturer of the stylus whether it fits a particular tablet.
The standard defined by Microsoft for tablets and pens gives hope. If everyone sticks to it, they should all fit together in the future. However, such devices/pens are still somewhat rare.
I use the Adonit Pro3 passive pen for my Lenovo tablet. It has convinced me. However, it only fits passive LC displays.

It is indeed a problem and I can't use the pen either. Apparently there are different versions of the Lenovo Yoga and the pen only works with a certain type. We have had bad luck... I bought a Callstel pen and it works OK to some extent.
