Problems solved by technology

This restart method pulls down the electrical signal and then pulls it up, which prolongs the process from pressing the reset button to completing the restart and loading system. Power failure phenomena such as the screen backlight and indicator lights affect the user experience, and it is difficult to meet the user's requirements for restarting the notebook.

Embodiment Construction

[0015] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0016] Such as figure 1 and 2 As shown, the present invention provides a notebook system restart control method based on an EC single-chip microcomputer. The programming content for the restart module includes the writing and packaging of restart action functions, restart action trigger functions, and restart sequence control functions. As the top-level function of the restart action process, the restart action function completely and uniquely controls a series of actions after the EC receives the restart command. The change of the system state is completed by this entry, ensuring that the restart command does not modify other state information of the system by mistake. , to ensure the reliability of the f...

Abstract

The invention relates to a notebook system restart control method based on an EC single-chip microcomputer, which is characterized in that it includes the following steps: S1: monitoring whether a restart command is received, if a restart command is detected, go to step S2, otherwise go to step S1 to continue monitoring ;S2: Enter the restart action, the restart action trigger function changes the state of the system to the restart state, the restart sequence control function excludes the control of nuclear power and screen signals, and only pulls down and pulls up some non-electrical restart signals according to the restart sequence; S3 : After the series of restart actions are completed, the system status will be switched to power on, and the notebook will load the operating system normally.

Description

technical field [0001] The invention belongs to the technical field of notebook system restart control, and in particular relates to a notebook system restart control method based on an EC single-chip microcomputer. Background technique [0002] EC (Embeded Controller, embedded controller) is a 16-bit microcontroller. When the notebook is powered on, the EC controls the timing of most important signals and external devices such as keyboards, fans, and charging indicators. When the notebook is connected to an external power source, whether it is turned on or turned off, the EC is running. EC plays an irreplaceable important role in the internal management of notebooks. [0003] The traditional way to restart a notebook is to restart after a power failure. When the EC receives the restart command, it enters the restart sequence control section, all electrical signals are pulled down in sequence according to the power-off sequence, the charging indicator light turns from on ...
