Regulation method of revolving speed of computer and mainboard system

Abstract

The invention provides a regulation method of the revolving speed of a computer and a mainboard system. The regulation method of the revolving speed of the computer comprises the following steps: an embedded controller receives a BIOS program write operation command which is sent by a BIOS processing unit and contains the type information of an electronic element, and stores the BIOS program into an embedded controller memory; the embedded controller carries out a read operation on the BIOS program stored in the embedded controller memory; and according to a result of the read operation on the embedded controller memory, the embedded controller selects a heat emission parameter corresponding to the type of the electronic element to regulate the revolving speed of a fan. The embodiment of the invention detects the type of the electronic element during starting up, the embedded controller selects the heat emission parameter corresponding to the type of the electronic element according to the type of the electronic element to drive the fan, the heat emission parameter corresponding to the type of the electronic element still can be selected when the configuration of the electronic element in the computer is changed, and the heat emission and the noise of the fan are caused to be mutually matched with the heat emission and the noise of the changed electronic element so as to better realize the control of the noise and the heat emission.

Description

technical field [0001] The invention belongs to the field of computer control, and in particular relates to a method for adjusting the rotational speed of a computer fan and a main board system. Background technique [0002] The boot control chip, also known as EC (Embed Controller, embedded controller), is a 16-bit single-chip microcomputer, and it also has a certain capacity of Flash inside to store the code of the embedded controller. During system start-up, the embedded controller controls the timing of the most important signals. In a notebook, whether it is on or off, the embedded controller is always on. In the shutdown state, the embedded controller keeps running and is waiting for the user's power-on information. After the power-on state, the embedded controller is used as the control of the keyboard controller, charging indicator light and other various indicator lights. It does not occupy system CPU (central processing unit) resources, and will not cause system...
