I have a Sony VAIO Laptop thats a couple years old with a 1080p touchscreen thats running WIndows 10 (Model name: SVF15N15CDB). The touchscreen works fine (although I've had some issues with it in the past, such as it not working at all with the windows 8.1 update then working fine with the windows 10 update). The problem is that it doesn't seem to pick up the stylus I have. I have a Logiix Pistol Point stylus and it doesn't seem to work at all even though the stylus works fine on my phone. However earlier the stylus sort of worked. Sometimes it would work for a couple minutes great, but then sometimes it would just completely stop working. However after I updated Windows (I was out of date with the updates) It stopped working entirely. Do you have any suggestions on what I can do to fix this?
