The present invention is a television that executes a process for transitioning between multiple power modes. Both the transition events and the power states may be factory-defined, or they may be user-configurable. The TV may have two sleep modes. In a quick-start mode, the screen is powered down but the operating system is spun-up, and possibly other major functional subsystems are user-enabled. In an energy-saving mode, fewer subsystems than quick-start mode, and possibly only components required to recognize a tactile control requesting a return to a power-on mode, may be enabled. Quick-start is less efficient than energy-saving mode, but results in much faster return to power-in mode. In some embodiments, power modes and transition events between them power modes may be automated, and either user defined or factory defined.
