ACPI
The Altos R700 server board supports the Advanced Configuration and
Power Interface (ACPI) as defined by the ACPI 2.0 specification. An
ACPI aware operating system can put the system into a state where the
hard drives spin down, the system fans stop, and all processing is
halted. However, the power supply will still be on and the processors
will still be dissipating some power, so the power supply fans will still
run.

The Altos R700 server board supports sleep states s0, s1, s4, and s5:
•
s0: Normal running state.
•
s1: Processor sleep state. No context will be lost in this state and
the processor caches will maintain coherency.
the processor caches will maintain coherency.
•
s4: Hibernate or Save to Disk: The memory and machine state are
saved to disk. Pressing the power button or other wakeup event
will restore the system state from the disk and resume normal
operation. This assumes that no hardware changes have been
made to the system while it was off.
