Problems solved by technology

[0006] Although the function of the system management bus SMBus with the embedded controller has been widely used in portable computer devices and even desktop computers, in the traditional design, it is often caused by the failure of the system management bus or the failure of the temperature sensor. As a result, the embedded controller cannot correctly read the temperature change of the central processing unit to control the action of the fan, and the temperature of the central processing unit is overheated, resulting in machine fusion, central processing unit burnout, and unpredictable machine damage.

Embodiment Construction

[0017] figure 1 It is a schematic diagram of the system connection of the present invention configured on a computer device. The computer device 1 includes a central processing unit 11, its system bus 12 is connected to a first bridge 13 (also known as the main bridge Host Bridge or North Bridge North Bridge), and a main memory 14 is connected to the first bridge 13. A PCI bus 15 (Peripheral Component Interconnect) is connected to the first bridge 13 , and various PCI devices 16 can be connected to the PCI bus 15 . A second bridge 17 (also called South Bridge) is connected to the PCI bus 15 , and then connected to an extended bus (Extended Bus), such as the ISA bus 18 .

[0018] An embedded controller 2 is connected to the ISA bus 18 . The embedded controller 2 mainly includes a keyboard controller 21, which can be connected to a keyboard device 22. The embedded controller 2 also includes a system management controller 23 (SMC), and is connected to a system management bus 2...

Abstract

The present invention provides one kind of abnormality detecting and computer protecting method, and one temperature sensor and one system management bus are used to detect abnormality and to protect computer. After the system is powered on, the temperature sensor is used in detecting the temperature of CPU unit and the temperature signal is fed via system management bus to one embedded controller. The temperature detecting result is returned. When the detection result is backed successfully, normal power-on program is execute, or else at least one continuous temperature detecting course is executed and in case of another unsuccessful backing, fault warning is issued and the computer is forced to power off.

Description

technical field [0001] The present invention relates to an abnormality detection and protection method of a computer device, in particular to a method for detecting whether the temperature sensor of the central processing unit of a computer device and the system management bus are abnormal, and then protecting the computer device accordingly Methods. Background technique [0002] Most of the notebook computers currently in use are equipped with an embedded controller (Embedded controller), which not only serves as a keyboard control function, but also has many additional functions related to system management (System Management). Usually the embedded controller is connected to the ISA bus of the computer device. The embedded controller mainly includes a keyboard controller (Keyboard Controller), which can be connected to a keyboard device. The embedded controller also includes a System Management Controller (SMC for short), which can be managed by a system. The system mana...
