I have an Asus x75v.
my problem is that the key A,D,F,J,K,L,Ö dont work.
i have tried to update the software. restarted my laptop and nothing happened. Please help!!
Have you noticed that all of the letters you mentioned are all in the same keyboard line? I suspect a bad circuit issue. All of those keys will need to be removed and cleaned, best done by a qualified technician.
