Does it always work after a fresh boot? What about sleep or hibernate? If you keep hitting keys enough do they start working again? Does a USB keyboard work fine?

I had issue with a set of keys on a Dell laptop (iirc ctrl, `, 5, 6, -, =, end, home) where if I left it they would seem to stop working, but if I pressed all the affected keys enough would start working again and carry on working until left again, as if had got "stuck". In the end I got a replacement keyboard off ebay and fitted that. Was not too much of a pain and were youtube videos showing how, and fairly cheap. It has been fine since.
