external keyboard did the same, ease of access onscreen keyboard the same, only numerical keys work. When I press any key narrator says "hidden". I'm waiting for the battery to die, to see if laptop resets. Last night I fell asleep while it was updating, in the morning battery was dead, I had to plug in the power supply to get started and updates installation was 96%, I used it all morning, turned it off around 1 p.m., at 6 p.m. I turned it on and This happened.
