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.
