ABSTRACT:
Power usage in a personal computer is reduced by repetitively performing the following sequence of steps: a. generate a wake-up signal in connection with a user beginning to interact with the computer; b. in response to the wake-up signal, switch at least a portion of the computer into a more fully powered mode; and c. keep the portion of the computer in the more fully powered mode only as long as the user is delivering input to the computer, and thereafter immediately switch the portion of the computer into a less fully powered mode. A detector issues a wake-up signal when a user begins to interact with the computer; and control circuitry connected to the sensor switches between the more fully powered mode and the less fully powered mode. The sensor may be mounted in a keyboard that includes an array of keys, and a sensor mounted in a position to detect use of the keyboard even when the keyboard is in an unpowered state.
