Abstract:
1. A preheating control system of an information processing device, comprising: a temperature sensing module, for sensing a temperature of a hard disk; a first controller, electrically coupled to the temperature sensing module, and having a primary control mode and a secondary control mode, wherein after receiving a power ON signal, the first controller shifts to the primary control mode, and determines whether the temperature of the hard disk satisfies an operating temperature scope or not, when the temperature does not satisfy the operating temperature scope, a heating control signal is generated, and when the temperature satisfies the operating temperature scope, an activate signal is generated; a heating module, electrically coupled to the first controller, and beginning to heat according to the heating control signal, so as to generate heat to heat the hard disk; and a second controller, electrically coupled to the first controller, and activated by the activate signal, wherein the second controller is configured such that after finishing activation, the second controller generates a finish signal to the first controller, such that the first controller shifts to the secondary control mode, and the second controller executes a boot program of the information processing device.
