Hello so, I have an ASUS X550JX second hand, So this problem started a few days ago, So the problem is that the "O, L and the ." keys stop working RANDMOLY and then sometimes RANDOMLY start working again. This is super annoying as I am a coder and I have to use those keys like a million times in a day and my laptop PIN also has those characters. The thing in common I found out is that on my keyboard the "O, L and the ." key are in a line. So this maybe an issue with something totally else. Thanks in advanced.
