I've had my Surface for almost 3 years now. Everything has been smooth sailing until recently. At first I had battery problems, but I was able to fix them with the help of the wonderful people on here. Now I've been having problems with my surface pen over the past couple of weeks. I'm a student and I hand write all my notes on OneNote. Lately, the pen has been spotty. I'll start writing and one or two words in, it'll stop writing. If i change pen or color on one note it starts writing - but only one or two words until it stops. It does the same when I'm writing on Word Docs and it's even spotty with just regular point and pressing. The purple button works to open OneNote. I have changed the battery twice, re-paired the pen multiple times, disabled the pen driver, and all my updates are up-to-date. At this point I don't know what else I can do. All my notes are on OneNote and not being able to amend/ add on to the notes is really screwing me over this term. Can anyone help?
