Hi every one
I have recently installed windows 10 on my Lenovo ideapad Z580. My laptop's alt, Esc and F4 keys stopped working. I had have the same issue last year but it solved by itself. Honestly I forget what I did last year to solve this problem. I had googled the problem and searched lots of forums and websites but most of users had this problem because their F4 key is combination of Fn and F4. In my case my F4 is not Combined by Fn keys.
I check my keyboard in the keyboard tester website and it seems the keys that I mentioned do not work there. The thing is I had this issue last year and I had checked my keyboard by a keyboard remapper namedSharpKeys to notice if it had a hardware issue and the keys ( alt, F4 and Esc ) did not work there too But it repaired by some work that I did and I forgot.
I had updated all of my drivers and I updated the BIOS before. But I checked for newer version of BIOS. But issue is not solved yet.
I will be thankful if anyone could help.
P.S.: I had started a similar topic in microsoft forum and nothing helpful came.
Win 10 Build version 1809

Welcome to the Community Forums.
To determine if the Alt, Esc and F4 keys are really not working, access BIOS and use these buttons. If those keys are not working even outside Windows OS environment, then the keyboard needs replacement.
