I have a Lenovo Y520 gaming laptop, on the keyboard there are certain keys not working correctly, and it's always the same ones. The 6, 7, y, u, h, j, n, and m keys are the ones that are causing the problems. (If you notice where the keys are on the keyboard, they make a diagonal-ish line, I'm not sure if that's important at all.)
To make the keys (temporarily) work again I ave to old the keys down util they start working again, this cold take a second to a few minutes, so typing paragraphs like this takes a log tie.
I've already tried cleaning the keys, that doesn't work, ad I' not sure what else to do, help is appreciated! :)
