I recently got a brand new laptop (Fujitsu Lifebook E546) and after installing Neon onto it the keyboard has stopped being fully responsive. Some keys work fine on their first press, but other keys, like backspace and space itself aren't that responsive and end up doing repeated inputs. Reinstalling the input drivers hasn't worked, and I'm not sure what to do now.

unresponsive an repeated input keys point to a hardware issue. Check you do not have any dust causing this.

I cleaned out any possible dust that was in the keyboard, but when I tried the laptop with its original drive that had windows on it the keyboard worked fine. Along with this, the keyboard is very inconsistent with typing;somtimes it will work fine, sometime it won't.
How do I fix this?

Nvm, loaded the default config of the bios and fixed the problem.
