Patent ID: 6972952

Claim:
A computer system having a CPU, a BIOS ROM to store a BIOS to perform a POST, and a power supply part to supply power to the CPU and the BIOS ROM, comprising: a temperature sensor to detect an internal temperature of the CPU; a power control circuit to cut off the power supplied from the power supply part when the internal temperature of the CPU detected by the temperature sensor exceeds a predetermined monitoring reference temperature; a CPU cooling part to cool the CPU according to the internal temperature of the CPU detected by the temperature sensor; and a selection part to selectively connect the temperature sensor to one of the power control circuit and the CPU cooling part, wherein the temperature sensor is connected to the power control circuit in an initial power supply, and wherein the BIOS that is stored in the BIOS ROM controls the selection part so that the temperature sensor is connectable to the CPU cooling part during the performing of the POST.
