my keyboard recently started doing this after not being used for a while, and the keys feel like their functions have shifted into different areas on the keyboard. It's not the Num lock problem, and i have tried a lot of different ways to try and fix this but it seems that nothing works. i don't want to give up on trying and having to pay to get this fixed. i can only use and external keyboard to type this on an on-screen keyboard. I'm starting to think the problem is to do with the actual keyboard its self.
