Hello,
I tested on Surface Laptop 5 15inch model with my slim pen 2 which works fine on my Surface pro 3. The touch sreen stopped working after some drawing. I am now 99% sure that the entire Surface Laptop 5 lines have this compatibility issue with stylus including Surface Slim Pen 2. Could you please report this issue to SL development team that SL5 lines are NOT compatible with Surface Pens (or any stylus)?? I think this is serious issue.
