Problems solved by technology

To put it simply, the advanced configuration power interface does not provide other mechanisms to reduce the power consumption of hardware components (such as CPU, display screen, which consumes a lot of power), so that the power saving performance is limited
Although some application software on the market provides related mechanisms to reduce the power consumption of hardware components, for example, when the notebook computer enters the battery mode from the power supply mode, it directly reduces the frequency of the CPU, but this method will seriously reduce the power consumption of the notebook computer. computer performance

Abstract

A power management method for a mobile device including a basic input output system (BIOS) and an embedded controller (EC) includes determining whether the mobile device is operated in a direct current (DC) mode, determining whether a loading of an operating system of the mobile device exceeds a predetermined value, adding a flag associated with the embedded controller in a physical memory of the mobile device when the mobile device is operated in the DC mode and the loading of the operating system exceeds the predetermined value, and reading the flag in the physical memory via the basic input output system, to notify the embedded controller to perform a power management process corresponding to the flag.

Description

technical field [0001] The invention relates to a power management method and a related device, in particular to a power management method and a related device capable of reducing power consumption. Background technique [0002] The capacity and endurance of notebook computer batteries have been greatly improved in the past few years, but today's processors consume more power than in the past, and the new generation of notebook computers introduces more and more power-hungry devices. That's why power management is becoming more and more important. You don't have to buy another battery to prolong battery life, a good use of smart power management policies can make a big difference. [0003] According to different levels of power supply, most of the hardware components in a notebook computer can operate in different states: stop, sleep, idle, running. Generally speaking, most of the power consumption on the motherboard is in the display screen, processor and hard disk. Alth...
