1. A computing device comprising:

  • a plurality of computing device components;

    a trackpad comprising a plurality of conductive plates; and

    a processor configured to;

    provide reduced power to at least some of the computing device components and provide increased power to the trackpad in response to a lack of user interaction with the computing device for a predetermined time period such that an overall power consumption by the computing device is decreased,activate the plurality of conductive plates of the trackpad to cause generation of an electric field over the trackpad using the increased power to the trackpad, andprovide normal operating power to the at least some of the computing device components and to the trackpad in response to an object entering the electric field over the trackpad without the object touching the trackpad.
