My HP Pavilion 15-e013TX’s built-in keyboard has some keys unresponsive (A,S,D,F,J,K & L to be specific) I tried most of the things on https://au.pcmag.com/how-to/9345/how-do-… but the problem still prosper.
Most of these are because the keyboard has failed or the connector is loose. It may work again if you reconnect the keyboard internally, but it’s generally due to a matrix failure. In your case, you picked the wrong system :-). The 15-e has a modular keyboard, which isn’t the case on the 15-p series. Refer to the Service manual to replace the keyboard and get the part number that matches the country you are in. The US part numbers are 719853-001 or 720597-001.
