Computer incorporating a power supply control system therein
First Claim
1. A computer incorporating therein a control system for controlling the operation of a power supply therein which supplies a plurality of DC output voltages to designated components of the computer to control on-off operations of the computer, wherein the control system comprises:
- means for detecting a power selection signal, generated when a power on/off key of the computer is actuated to control the on-off operations of the computer, to provide a detected power selection signal as a power detection signal;
means for producing a first, a second and a third mode control signals when predetermined instructions corresponding to the signals are given by the computer user, respectively;
a first generation means, responsive to the first mode control signal, for generating a first power control signal and a selection control signal by using the power detection signal;
a second generation means, responsive to the selection control signal and the second and the third mode control signals, for generating a second power control signal by utilizing the power detection signal; and
a combining means for logically combining the first and the second power control signals to generate a definitive power control signal and to provide it to the power supply, thereby selectively supplying the DC output voltages to the designated components of the computer to control the on-off operations of the computer.

Abstract
A computer incorporates therein a control system for efficiently turning on and off a power supply on and off therein to control on-off operations of the computer. In the control system, a power detection signal is derived first based on a power selection signal generated when a power on/off key of the computer is actuated to control the on-off operations of the computer at a signal detector. And then, at a first generator, a first power control signal and a selection control signal are obtained from the derived power detection signal in response to a first mode control signal. Next, a second power control signal is derived from the power detection signal, the selection control signal and a second mode control signal at a second generator. Finally, the first and the second power control signals are logically combined at a second logic circuit to generate and provide a definitive power control signal to the power supply, thereby selectively supplying DC output voltages to designated components of the computer to control the on-off operations of the computer.
