Patent ID: 8719597

Claim:
A power control system for use in a computer system and for receiving a power signal supplied by a power supply module to execute a boot procedure by a control signal inputted by a power button; wherein the power signal is a first power signal or a second power signal; the first power signal is transformed from an alternating current power signal and the second power signal is transformed from a direct current power signal, the power control system comprising: a control module used for receiving the control signal; a power management module electrically connecting to the control module and receiving the power signal to output an auxiliary power; a first switch module electrically connecting between the control module and the power management module, wherein the first switch module is used for controlling the power management module to output the auxiliary power through the first switch module to the control module by the control signal, wherein the control module performs a standby mode when the auxiliary power is received; and a second switch module electrically connecting to the control module and the first switch module and controlling the first switch module; wherein after the control module receives the control signal, the control module is used for determining whether the control signal is continuously received until a predetermined time; if yes, the control module controls the first switch module to transmit the auxiliary power continuously by the second switch module and receives the power signal to execute the boot procedure; and wherein the control module is further used for determining whether the received power signal is the first power signal or the second power signal; if the power signal is the second power signal and the control signal is not continuously received until the predetermined time, the control module is used for controlling the first switch module to cut off the auxiliary power with the second switch module; if the power signal is the first power signal, the first switch module is further used for controlling the power management module to output the auxiliary power to the control module with the first power signal.
