Abstract: A Computer based on a dual processing structure, with a main processing subsystem associated to an alternate processing subsystem. The main subsystem includes a main processor, a keyboard and a display, and the alternate processing subsystem has a quicker response time than the main processing subsystem. Additional multiplexing means are used for sharing said display and said keyboard between the two processing subsystems. The computer includes a powering control unit (40) for controlling the powering of the components of said main or said alternate processing subsystem, said powering control unit being controlled by a main power-on control and a alternate power-on control keys. The actuation on the main power-on control key causes the power-on control unit to power the two processors while actuating the alternate power-on control key causes the powering of the alternate processing subsystem only.

Abstract: A power state sub-system changes the power state of a computer system associated with the sub-system. The sub-system has (1) a wireless receiver responsive to control instructions including IDs for plural different computer systems and (2) a controller that changes the power state of the system associated with the sub-system in response to the instruction having the ID for that associated system. The sub-system is powered independently of the computer system, so its ability to receive control instructions is unaffected by the system's power state.
