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.

Abstract: A notebook computer (10) is provided with a collapsible keyboard structure (12) in which, in response to closing of the computer housing lid (30), the key return spring portions (80) of the keyboard are shifted away from their normal underlying relationships with the keys (40) and the keys (40) are forcibly retracted to a storage/transport orientation in which the overall thickness of the keyboard structure is reduced by an amount essentially equal to the stroke distance (D) of the keys (40). When the lid (30) is subsequently opened, the key return spring portions (80) are shifted back to their normal underlying relationships with the keys (40), and the keys (40) are forced outwardly by the return spring portions (80) to their extended, operative orientations above the return spring portions (80).
