What is the actual mechanism (or circuitry, I presume) that allows a computer to stop drawing power from the charger?

I know this! I learned it in electrical trade school. Granted that was 10 years ago so this may be rough.
Diodes only allow the flow of electricity one way. You can install “GATED DIODES” now think of this gate as a valve in your kitchen sink. The gates had a voltage sensory to be activated simply. Now say the gate opens or disconnects a 5.9v, when the float battery voltage reaches this level the gate opens and the flow stops.
This is veeeeery rudimentary and simple but yeah, gated diodes.
Diodes are also the reason when you are walking around with your phone plugged in and the charger in hand looking for an outlet the phone doesn’t backfeed 120v into the prongs on the charger
