a button stopped working on my laptop's keyboard ( asus rog strix). the button A and sometimes the buttons 1 and Q dont work, but in pretty unusual way. Sometimes they suddenly start working again without any reason. Then, after a couple of hours, stop working again and without any reason too. That have started like 2 weeks after asus support have replaced motherboard, because of a different issue (not sure its related, but decided to mention). It continues a month already. Sonetimes buttons work properly, sometimthey don't. Another thing i think is worth to mention- during a periods of time, when the A button doesnt work and i apply some pressure on it- it types A for once. Please advise what can i do to fix this issue, i really need help.
