Sure, why not? It would be an incredibly low powered PC and you'd have to be a fast typer, but you might manage to power something. Probably no chips capable of displaying at that power level though

If your aim was to power a PC then you wouldn't use a normal keyboard. Why not have something much like a typewriter of old, with a long travel distance for the key? Instead of moving a stamp on a stick, use that kenetic energy to generate power instead. Surely you could get a lot more power out it it that way.
