I believe that many Win7 system users do not know what ACPI is in the computer, so even if there is a problem with ACPI, they do not dare to operate it at will. Today, the editor of Huajun brings you a simple and easy-to-understand solution. I hope you will support and share the carefully selected content. If you like it, hurry up and get it!

1. What is ACPI?

ACPI is the abbreviation of Advanced Configuration and Power Interface, generally translated as Advanced Configuration and Power Management. It is a power management standard jointly developed by Intel, Microsoft and Toshiba.

2. What is the use of ACPI?

ACPI is a part of Windows (starting with Win98). It helps the operating system to reasonably control and allocate the power of computer hardware devices. With ACPI, the operating system can turn off different hardware devices as needed based on the actual conditions of the device. For example, in Win7 or Win8 systems, when the system sleeps, the system stores the current information in the memory and only keeps the memory and other key hardware components powered on, putting the computer in a highly power-saving state. Of course this is only a small part of her capabilities.

ACPI is powerful, it can achieve:

In addition to the advanced system 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 the editor. With the above detailed introduction, I believe you will have a better understanding of ACPI.
