An ACPI driver is software that allows your computer to work along with your ACPI hardware correctly. ACPI stands for Advanced Configuration and Power Interface. It is a power management specification that an operating system uses to control the amount of power that each of the computer’s devices receives. With the ACPI installed, a computer can turn certain devices off if they are not being used. This will conserve energy and prolong the life of the device. The primary focus of the ACPI is to consolidate and improve the computer’s usage of power. With the ACPI in place, an operating system can go into four different modes of power usage. These modes include working, sleeping, soft off, and mechanical off. When the system is in working mode, all parts that are being used by the PC user are using full power. The sleep mode is broken down into four subdivisions, which are S1 through S4. The sleep modes are different variations of the system being turned off but can be powered up quickly. Soft off and mechanical off are very similar modes. The only difference is that mechanical off means that the system is completely shut down and unplugging the power cord is safe. In order for the ACPI to run cohesively with the computer and its operating systems, an ACPI driver is crucial. Checking for ACPI driver updates on a regular basis is highly recommended.
