The Advanced Configuration and Power Interface (ACPI) specification is a computer industry specification developed by HP, Intel, Microsoft, Toshiba, etc. to achieve power management at the operating system level. The ACPI specification divides the operating state of the computer system into six types: S0, S1, S2, S3, S4, S5, and S6. The system power consumption corresponding to the six states decreases in turn, and the system power consumption corresponding to S0 is the highest, and S5 corresponds to The system consumes the least power.

The S4 state, also known as the sleep state, is also referred to as Suspend to Disk (STD) state. When the computer system goes to sleep, the computer system copies the current system working state (all the data in the memory) to the hard disk, and then turns off the main power. The computer system after entering the sleep state is as "quiet" as the shutdown in the usual sense, and the user can even cut off the power completely, because unlike the memory, the data saved to the hard disk does not disappear due to the power failure. When the computer system wakes up from the sleep state, the system working state previously stored in the hard disk is read out and reloaded into the memory, so that the computer system completely returns to the working state before the sleep, without reopening File or run the program.
