no, to do the battery run-down test, you must not have it plugged in!
otherwise you'd just be powering it from the adapter, and you'd never
run out of juice.
so, the steps are:
1. bootload your HB with pcode_hb.s19. you should see the Interactive
C message and a beating heart on the lcd.
2. unplug your HB from everything. time how long it takes for the
board's battery to run out of power.
you should get 8 to 10 hours if the battery was fully charged when you
started.
