A letter on my keyboard is stuck and just keeps typing over and over by itself

• The letter n on my laptop seems to randomly get stuck and take over, typing itself over and over without me touching the keyboard. I have taken the key off and cleaned under it  and uninstalled the driver.

If cleaning the key wasn't enough, then the mechanism has failed and you need to replace the entire laptop.

I could just replace the keyboard though?

Yes.  Sorry. I meant to write keyboard not laptop.

It doesn't always do it. Sometimes it is fine for a while and then suddenly it starts again. I am in India and it is currently super humid here, and also dusty. I am wondering if this might have something to do with it. If I shut it down for some time and let it cool down and then reboot it, sometimes it is okay.
