Method and computer system for thermal throttling protection

A computer system, comprising:

• a central processing unit (CPU);
• a thermal sensor for detecting the temperature of the CPU;
• a main basic input/output system (BIOS), executed when the computer system is powered on;
• and
• an embedded controller initialized by the main BIOS, and
• a sub BIOS executed by the embedded controller to obtain an upper temperature limit and a lower temperature limit set by the main BIOS, wherein the sub BIOS compares the temperature of the CPU detected by the thermal sensor with the upper temperature limit and sends a system control interrupt (SCI) event to the main BIOS through the embedded controller when the temperature of the CPU is higher than the upper temperature limit,
• wherein when receiving the SCI event, the main BIOS enables a throttling function to perform a throttling operation on the CPU or shuts down the computer system.

A non-transitory storage medium storing a computer program with a plurality of program code segment, wherein the program code segment are used for being loaded to a computer system and enabling the computer system to execute an automatic thermal throttling protection method, and the computer system at least comprising an embedded controller, a main basic input/output system (BIOS), a sub BIOS, a central processing unit (CPU) and a thermal sensor, the automatic thermal throttling protection method comprising the steps of:

• executing the main BIOS for initializing the embedded controller to execute the sub BIOS when the computer system is powered on;
• the sub BIOS obtaining an upper temperature limit and a lower temperature limit set by the main BIOS and obtaining a temperature of the CPU through the thermal sensor;
• the sub BIOS comparing the temperature of the CPU with the upper temperature;
• the sub BIOS sending a system control interrupt (SCI) event to the main BIOS when the temperature of the CPU is higher than the upper temperature limit;
• and
• the main BIOS enabling a throttling function to perform a throttling operation on the CPU or shutting down the computer system when receiving the SCI event.
