ACPI features include:

Plug and Play (including bus and device enumeration)

Power management control of individual devices, add-in boards (some add-in boards may require an ACPI-aware driver), video displays, and hard disk drives

Methods for achieving less than 15-watt system operation in the power-on/standby sleeping state

A soft-off feature that enables the operating system to power-off the computer

Support for multiple wake-up events

Support for a front panel power and sleep mode switch

The Server Board S875WP1-E supports sleep states S0, S1, S2, S3, S4, and S5. When the server board is operating in ACPI mode, the operating system retains control of the system and the operating system policy determines the entry methods and wake-up sources for each sleep state. Sleep entry and wake-up event capabilities are provided by the hardware but are enabled by the operating system. The following is a summary of the supported sleep states:

S0: Normal running state.

S1: Processor sleep state. No context will be lost in this state and the processor caches will maintain coherency.

S3: Suspend to RAM (Instantly Available PC Technology).

S4: Hibernate or Save to Disk. The memory and machine state are saved to disk. Pressing the power button or another wake-up event restores the system state from the disk and resumes normal operation. This state assumes that no hardware changes were made to the system while it was off.

S5: Soft off. Only the RTC section of the chipset is running in this state.

CAUTION

The system is off only when the AC power is disconnected.

Table 8 lists the system states based on how long the power switch is pressed, depending on how ACPI is configured with an ACPI-aware operating system.
