answer:Mine did a couple of weeks ago. Solving it was easy. However, I needed a mouse to reset it. What had happened was that somehow the control panel setting for mouse movement was being reset (turned off) at the point of booting up. What I did – got a small USB mouse after booting up. Go to control panel Go to Mouse That opens a popup with Mouse Properties (your Toshiba is probably a different model than my Toshiba) but there was a box there that said “disable touchpad” and it was checked. Uncheck it, save, and you are done This happened to me right after the last set of Microsoft updates, so something in that sequence screwed things up.
