A couple weeks ago a collection of keys on my laptop started randomly inputting. It was always the same set of keys, and there was no pattern to when the problem would start. I was fairly certain it was not a software issue because the problem existed on both Windows and Ubuntu (dual boot). I thought I had fixed the issue by installing a new keyboard, but two days later another collection of keys started randomly activating. Finally, the entire keyboard became completely unresponsive.
What would the next step be in troubleshooting this issue? Should I buy a second replacement keyboard ($20) and see if that resolves the issue? Or should I take it into a shop because it is a motherboard issue? The laptop is a Dell Latitude E7450 and is not under warranty.
