I dropped my laptop (case was closed) today. Later certain adjacent letters started not working sporadically: 8 i k ,
Notice that they are vertically adjacent on the keyboard. Occasionally, they won`t work at all. Most often they work only when press the letter to the right or left immediately before, e.g.: jk or ui
Should try disassembling and cleaning the keyboard? Or is there some diagnosis you would recommend first?
This is a Dell Latitude E6410 laptop. I got it as a refurbished computer, and it has been very reliable.
