<p>PROBLEM TO BE SOLVED: To control the operation of a computer by effectively switching the power supply to the computer. SOLUTION: In accordance with a 1st mode control signal, a 1st control signal generating means PCSG 150 generates a 1st power source control signal PCS 1 and a selection control signal BCS 3 by using a power detecting signal. In accordance with the selection control signal BCS 3 and 2nd and 3rd mode control signals, a 2nd control signal generating means PCSG 160 generates a 2nd power source control signal PCS 2 while using a power detecting signal PDS. Then, a combining means DPCSG 170 logically combines the 1st and 2nd power source control signals PCS 1 and PCS 2, generates a final power source control signal DPSC and supplies it to a power unit 200 and plural DC voltages are selectively supplied corresponding to required elements in the computer so that the ON/OFF operation of the computer can be controlled.</p> |
