Some keys on keyboard is not working with Windows 8.1

[Malinda A]

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.

u tried external keyboard

An external keyboard works but I need my work (aka laptop) to be portable (and not to mention lugging around an external keyboard is troublesome) because I am a student.

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.

vuhuuu, I have the exact same problem. The letter N seems very affected by this. Weird.

Did you find a solution?
