What is the ACPI of the Win7 system? Win7 system ACPI detailed introduction

I believe that many users of Win7 system don't know what ACPI is in the computer, so even if there is a problem with ACPI, don't dare to operate it. Below, Xiaobian will come to you to introduce the functions of ACPI and ACPI.

a, ACPI what is?

ACPI is an acronym for Advanced Configuration and Power Interface. It is generally translated into advanced configuration and power management. It is a power management standard jointly developed by Intel, Microsoft and Toshiba.

Second, what is the use of ACPI?

ACPI is part of Windows (starting with Win98). It helps the operating system to properly control and allocate the power of computer hardware devices. With ACPI, the operating system can turn off different hardware devices according to the actual situation of the device. . For example, in Win7 or Win8 system, when the system sleeps, the system stores the current information in the memory, and only keeps the power of several key components such as memory, so that the computer is in a state of high power saving. Of course this is only a small part of her function.

ACPI is powerful and can be implemented:

In addition to the system advanced configuration and power management mentioned above, it also implements device and processor performance management, configuration/plug-and-play device management. , system events, temperature management, embedded controllers, and SMBus controllers.

The above is the function of ACPI under Win7 system introduced by Xiaobian. With the above detailed introduction, I believe you will have a better understanding of ACPI.
