Is there any way, today, to tell a "good" keyboard / keyboard chip -- i.e. one that handles sleep, power-save, wake-up correctly, and the many we still find that keep the CPUs awake? For the moment, it seems hit-or-miss whether I grab a keyboard that's "good" or "bad" - even one recently purchased.

the keyboard may also be the part that is keeping your CPU out of power savings state
that "tax" is attributed to the device, not the cpu.
