It depends on the laptop.  The older ones just have simply hardware
control of charging, as you described.  Newer ones have firmware control
of charging, and some allow you to vary the parameters.

In theory, more intelligent control of the battery should prolong its
life (though mine only lasted about two years, so that's not an
improvement).  And I can see the potential for really bad settings to be
set.  I hope the firmware has sensible defaults for when an OS doesn't
try to control the charging.
