3.3 ACPI
The Advance Configuration and Power Interface (ACPI)-aware operating system can place the
system into a state where the hard drives spin down, the sytem fans stop, and all processing is
halted. In this state the power supply is still on and the processors still dissipate some power,
such that the power supply fan and processor fans are still running.
Note: ACPI requires an operating system that supports this feature.
The ACPI sleep states discussed below are defined as:
•
s0: Normal running state
• s1: Processor sleep state. No content is lost in this state and the processor caches
maintain coherency.
