Chosen Solution
So I got a double click problem and had to replace the “rubber part”, which is under the hinge: https://www.replacementlaptopkeys.com/pr… It seems like it won’t hold in place anymore so the key does not work properly. Should it be glued? Did anybody tried to replace it?
So I had to glue it for it to hold, but the butterfly part which I ordered was from 2017 model (mine is 2016) so the key was lower and didn’t work properly in the corners. But it solved my double click problem and I been happy with it for a while. Later I got same double click on another key and had to replace my keyboard under the warranty. I got new 2017 keyboard model and new battery as a nice bonus. 2017 model is much better so I would highly recommend anybody with such issue to replace the whole keyboard.
