I can press all the multimedia keys as if the fn key is pressed permanently, but I can't use F5-F12. I have tried resetting from Armoury Crate and pressing Fn+Esc, but since fn doesn't work it's useless.Is there anything I can do?
I have managed to "solve" the problem, to my own embarrassment the problem was that I had the fn and menu keycaps physically swapped. I tell this so that the next idiot who has the same issue will find the solution.
Yes, the keyboard has been working perfectly for three months until this morning. I can type perfectly in Spanish with accents and ñ, so that shouldn't be the problem.
It does not work, I guess because the Fn key does not respond no matter what.(It appears faded out on the keyboard in Armoury Crate).*In case it is of any use, my keyboard has an ISO layout (Spanish).
