My FGHJKL keys started failing all at the same time, its not always, but very often all of them stop working. I have tried everything from here: One or more keys on the keyboard do not respond - Apple Support
Read a couple of posts from different people that had the same issue, no solution... its always the same keys, at the same time. I can spend 1h without any issue, or have the problem 20 times in 1min. They stop working, and after a while they work again..
I have removed, cleaned and replaced them back, still the same.
If anyone has had this problem and found what was the solution to it please help. Every answer i have read about it is the same, restart,... its very specific that its always the FGHJKL keys for different people, and all at the same time.
