My laptop keyboard works except for a few keys (s, c, b, n, and space bar). I've checked that the toggle and filter keys functions are off and I've uninstall and reboot my laptop. I've changed language multiple times and nothing work.
I have the exact same problem. And the same keys not working on my Asus laptop (N550J). For me also the enter doesn't work. Numpad enter works. Time to time if I press letter N 20 times it finally works 1 time. Same with other keys. Took it to the service. They said its software issue and sent me away. External keyboard works without any problems and all the letters work. Restaring computer doesn't help.
Did service help you get a solution. For me there are times when all the letters and keyboard work fine. And then they just stop working again.
