First of all, this forum has been great learning new tricks and what my new SP3 is capable of, and has been a great resource as I am learning how to use this beast! However, I bought an SP3 for school as the handwriting and note taking capabilities on oneNote seemed to be unmatched. Naturally the pen that came with the SP3 was a tool I was excited about, but it is not working right. Here is everything I have gone through: The pen works for writing, and both buttons on the side work great. When I pair the pen, I push the eraser button for 7 seconds and the led lights up as it should, and syncs to the SP3. From everything I read, it is performing properly. But when I push the eraser button it does not work with one note. No new page, no double click for screen shot. I have uninstalled and reinstalled both the oneNote app, and desktop version with no success. I have updated any and all updates. I have gone through Microsofts trouble shooting. Nothing works. NOW. I decided to reset to factory settings, and reinstall windows 8.1. but it says its missing files to do so. I followed the directions to make a reboot usb from the troubleshooting website, and when I go to boot from that it says it is not a correct device. I feel as though this SP3 is just not quite right.. and have no clue what to do from here. Any help would be appreciated! Thanks!
