My hp laptop Model (15-n243sx) keeps displaying num 7(when turning off the numlock right arrow keeps pressing instead) from numpad as if the key is physically stuck (it is not, and on pressing it nothing happens) and sometimes the touchpad would stop working until a keyboard button is pressed.
Tried the following:-
1.Booted in safemode the issue still persists.
2.Uninstalled the keyboard and touchpad drivers.
any suggestions would be appreciated.
If you already reinstalled drivers, then I would remove the keyboard, inspect the ribbon, and make sure it is seated properly. Oh and can you try plugging in an external keyboard to see if the issue persists?
