1. In a stylus for use with a display screen of a computing device, a method for arming and managing power consumption of a haptic feedback component in the stylus, the method comprising, prior to actuating the haptic feedback component to produce haptic output:
at least on condition of detecting a first user interaction with the stylus, transmitting power for at least a first time period to a haptic circuit communicatively coupled to the haptic feedback component, wherein transmitting power for at least the first time period to the haptic circuit comprises executing a haptic driver that causes the haptic feedback component to vibrate at a user-imperceptible magnitude for at least the first time period;
at least on condition of determining that the first time period expires, determining if a second user interaction with the stylus is detected;
if the second user interaction with the stylus is detected, then continuing to transmit power to the haptic circuit to cause the haptic feedback component to vibrate at the user-imperceptible magnitude; and
if the second user interaction with the stylus is not detected, then ceasing to transmit power to the haptic circuit.
