Abstract: A method for preheating an electronic system when booting in an environment with low temperature and an apparatus using the same are provided. The electronic system includes at least a processor, at least a first controller, and at least a second controller. The method includes: the first controller checking whether the initialization of the second controller is successful or not after the electronic system boots, wherein the first controller include a basic input/output system; entering a preheating mode when the initialization of second controller has failed, wherein in the preheating mode, the processor is powered continuously and a turbo function is enabled, so as to provide a heat energy for heating the electronic system; and stopping the preheating mode and rebooting the electronic system.

Abstract: An automatic thermal throttling protection method is described. a computer system executes a main BIOS for initializing an embedded controller when the computer system is power on or boots. And the sub BIOS of the embedded controller is also executed. The sub BIOS of the embedded controller obtains an upper temperature limit and a lower temperature limit set by the main BIOS, and obtains a temperature of the CPU through a thermal sensor. The sub BIOS of the embedded controller compares the temperature of the CPU with the upper temperature limit. When the temperature of the CPU is higher than the upper temperature limit, the sub BIOS sends a system control interrupt event to the main BIOS through the embedded controller. 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.
