Power

Motive
The motive, power, 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 need the same as a sim can, or while it is daylight they can step outside and use the "Recharge" command.

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

Aspiration
The Aspiration called Power is unused but can be accessed by the Sim Modder with boolprop testingcheatsenabled. An image doesn't exist for it. In Free Time the Aspiration Benefits for Power is the same as Popularity.
