Power

The Power motive is only available in The Sims 2: Open for Business Expansion Pack. Only a Servo will have it.

The Power motive is like the Energy motive for a Sim. Servos can fill this by sleeping, the same as Sims can, or they can go outside while it is daylight and use the "Recharge" command.

If this need gets too low, Servo will either go outside to recharge, or go berserk and require repairs by a Sim with a high Mechanical Skill, preferably one with a gold talent badge in Robotics.
