Peculiar flaw in keyboard debouncing

I am having persistent problem with keyboard debouncing algorithm in Dell business laptops. (Mine being M4800, but I reckon Latitudes and some Vostros come with the same keyboard and the same corresponding routine in BIOS.)

I may be ‘too quick’ to hit the space-bar with my thumb right after typing another key.

The likely problem in the algorithm: As soon as it registers my hitting space, it terminates debouncing of the previous key. Yet that may still be “bouncing”… The other key then gets registered another time, after the space:

If I never rcorrected it, ,the outcome ewould dlook like ethis.

It does not happen that often, but it does happen often enough to affect my typing comfort and effectiveness.

The problem has persisted across several BIOS releases, irrespective of overall debouncing improvement between versions. I’m now on A14 (M4800).
Actually, I believe it somewhat worsened between A10 and A14 (I went from A10 to A14, skipping versions in between.)
