A hard disk temperature monitoring device for monitoring a temperature of a hard disk in a computer system is provided. A hard disk stores an operating system. A basic input/output system (BIOS) has a setting configuration. When the setting configuration is a first setting value, operation of the hard disk is restored. When the setting configuration is a second setting value, the operation of the hard disk is stopped. A thermal sensor detects a temperature of the hard disk. A keyboard controller (KBC) is electrically connected to the thermal sensor via a data transmission channel for detecting the temperature of the hard disk in real time. If the KBC detects that the temperature of the hard disk rises to a first predetermined temperature, the setting configuration is set to the second setting value, and the BIOS stops the operation of the hard disk according to the second setting value.

An apparatus and method are provided to monitor the current temperature of a hard drive in a computer system protect, and protect the hard drive from being overheated. The apparatus includes a thermal sensor and a data input/output module. The hard drive stores at least one application program. The thermal sensor senses a current temperature of the hard drive. When the thermal sensor senses that the current temperature of the hard drive ascends to a first preset temperature, the data input/output module ceases the hard drive from being accessed. When the thermal sensor senses that the current temperature of the hard drive descends to a second preset temperature, the data input/output module allows the hard drive to be accessed.

A method for protecting a battery of an electronic device from overheating is provided. The method senses the temperature of the battery and conduct an unloading action when the temperature of the battery ascends to an unloading temperature. The method further halts the unloading action when the temperature of the battery descends to a lowest critical temperature, wherein the unloading temperature is not lower than the lowest critical temperature.

A magnetic storage device capable of recording a drop height and an electronic device using the same are presented. The magnetic storage device includes: a G-sensor, installed in the magnetic storage device, for outputting a first trigger signal when the magnetic storage device starts to drop and outputting a second trigger signal when the magnetic storage device stops dropping; a timer, for calculating a duration between the first trigger signal and the second trigger signal, and recording the duration as a drop time; a logic operation processor, having a built-in height calculation formula, for calculating a drop height according to the drop time; and a memory unit, for storing the drop time and the drop height. An electronic device using the magnetic storage device is also presented, which is capable of record the actual drop height when a drop event occurs on the electronic device.

A process for a monitor working in a DPMS mode applies when a monitor ends a working mode and enters the DPMS mode. In the DPMS mode, when the signal processor of the monitor detects there is no signal input to the connecting interface, the signal processor will be off and inform the micro-controller to open the signal detecting function to find whether there is a signal input to the connecting interface. When the micro-controller detects there is no signal input for a certain of time, the micro-controller will enter the sleep status. As a result, the purpose of saving the electricity can be achieved.

A preheating control system of an information processing device and a control method thereof are described. The system includes a temperature sensing module, a first controller, a heating module, and a second controller. After receiving a power ON signal, the first controller shifts to a primary control mode and determines whether temperature of the hard disk satisfies an operating temperature scope or not. When the temperature does not satisfy the operating temperature scope, the heating module is used to heat the hard disk. When the temperature satisfies the operating temperature scope, the first controller shifts to a secondary control mode and activates the second controller to execute a boot program of the information processing device, thereby improving system stability.

A boot determining method of an electronic device is used to determine whether to boot the electronic device having at least one storage. The boot determining method includes: receiving a start signal; detecting an ambient temperature; detecting whether the at least one storage has a heating module; comparing the ambient temperature with a temperature threshold; reading storage information; determining type(s) of the at least one storage according to the storage information; and determining whether to boot the electronic device after receiving the starting signal, according to a determining condition. The determining condition includes the type(s) of the at least one storage; whether the environment temperature is lower than the temperature threshold; and whether each of the at least one-storage has the heating module.

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.
