I believe there are many Win7 system users do not know what is ACPI in the computer, so even if there is a problem with ACPI, also dare not arbitrarily to operate it. Below, the small series to tell you a specific about ACPI and ACPI functional role.
One, what is ACPI?
ACPI is the acronym for Advanced Configuration and Power interface, which is generally translated into advanced configuration and management and is a power management standard developed jointly by Intel, Microsoft and Toshiba.
What's the use of ACPI?
ACPI is part of Windows (WIN98), which helps the operating system reasonably control and distribute the power of computer hardware devices, with ACPI, operating systems can shut down different hardware devices as needed, depending on the actual device. such as Win7 or WIN8 system, system sleep, the system to store the current information in memory, only a few key components of memory, such as the power of hardware, so that the computer in a highly energy-saving state. Of course, this is only a small part of her function.
ACPI is powerful, and it can achieve:
In addition to the system Advanced configuration and power management mentioned above, it implements device and processor performance management, configuration/Plug and Play device management, system events, temperature management, embedded controllers, and SMBus controllers.
