ACPI (Advanced Configuration and Power Interface), i.e. ACPI.The ACPI following several modes that has been in operation:
S0: normal mode.
S1: standby mode, only have CPU to quit work, other equipment are still in powering state.
S2:CPU closes, and S1 is about the same.
S3: standby mode, after system is switched to this pattern, except internal memory, the power supply of other equipment of computer all will be interrupted, and only have internal memory to rely on electric power maintaining data (because internal memory is volatibility, as long as outage, data have not just had) wherein.When wishing to recover, just can directly return to the front state of standby like this.The not power consumption fully of this pattern for example, if therefore under holding state, power abnormal (having a power failure), just can only be started shooting so next time again, thus before standby not the data of preservation all can lose, but the resume speed of this pattern is the fastest.
S4: park mode, after system is switched to this pattern, system can automatically all dump to the data in internal memory on hard disk in a hibernation file, then cuts off the power supply to all devices.When recovering, system can directly be read in internal memory by the content of hibernation file from hard disk like this, and returns to the state before dormancy.Therefore the not power consumption fully of this pattern, be not afraid of abnormal electrical power supply after dormancy, but cost is to need one and physical memory hard drive space of a size (present hard disk has been crossed over the TB rank, and big capacity hard disk is more and more cheap).And the resume speed of this pattern is slower, depend on memory size and hard disk speed.
S5: shut down computer.
SMI:System Management Interrupt system management interrupt.
