I have an Asus x541UVK running Windows 10 and a few days ago, the 6, 7, y, u, h, j, n, and m keys stopped functioning on my laptop. I tried disconnecting and reconnecting the keyboard ribbon cable but it didn't make a difference. My c key has now also stopped working.
An external keyboard works fine so it's possibly a hardware issue. I've had this issue a few months before with the same keys not working, however, I can't remember what I did to fix it. Any help is appreciated.
