Embodiment Construction

[0045] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0046] The power-on process is critical for electronic devices. In the booting process, the power-on timing signal sent by the south bridge chip is particularly important, wherein the power-on timing signal is used to instruct the electronic device to provide power to each functional module (such as the system bus, memory module, central processing unit, etc.) according to the preset power supply sequence. (English: Central Processing Uni...

Abstract

The invention discloses an electronic device startup method and an electronic device, and aims to solve the problem that the electronic device cannot be normally started up because a South Bridge chipencounters with an abnormal environment in the prior art. The method specifically comprises the steps that a control module receives a first power-on time sequence signal sent by a startup module; when the control module determines that a working state of the startup module is abnormal according to the first power-on time sequence signal, data stored in the startup module is restored to initial data; the control module receives a second power-on time sequence signal sent by the startup module according to the initial data; and the control module starts the electronic device based on the second power-on time sequence signal.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method for starting an electronic device and the electronic device. Background technique [0002] Different functional modules in electronic equipment (such as system bus, memory module, central processing unit (English: Central Processing Unit, referred to as: CPU), etc.) have different operating voltages. For example, the operating voltage of the south bridge chip is 1.2V or 1.0V, etc., The working voltage of the system management bus is 3.3V, the working voltage of the memory module is 1.35V, the working voltage of the CPU is 1.2V and so on. When the electronic equipment is turned on, it is necessary to provide each functional module included on the main board of the electronic equipment with the voltage required for starting the functional module (that is, the operating voltage of the functional module) based on the power-on sequence signal sent by the south bridge chip. ...
