MY keyboard has been not working properly. After 1 automatic update from Windows in October, I was unable to use my keyboard or the touchpad unless I went to the keyboard function window and adjusted the blink speed of the cursor. Afterwards, I could at least type.
I have since deleted the driver
and reinstalled it, rather it was reinstalled automatically on restart. It has given me use of the touchpad, but now some of the buttons are not associated properly. I intend to type an L and a 3 comes out.
