On a T430 (2342-CTO) I can confirm that both force_discharge and
inhibit_charge behave as expected, both when the battery is above and
below charge_start_threshold.  Input validation also works
as-expected.  The only oddity I noticed is that force_discharge has a
delay taking effect (<1 sec) transitioning from 0 to 1 (but not 1 to
0).

Thanks for working on this!
