Hi. I suddenly had this problem. I used the on board windows recovery with no result. There was no screen pointer and the touchpad seemed dead.
I didn’t want to open the box so found my way to the drivers using keystrokes. With nothing to loose, I simply deleted the touchpad driver and everything returned in perfect working order on reboot!
If you have this problem it may be worth a try. In my case it seems to have been a corrupted driver issue or perhaps because the wrong driver got installed during an update?
