Keyboard And Mouse; Acpi - NEC N8100-958F User Manual

2-20 General Description

Keyboard and Mouse

The keyboard/mouse controller is PS/2-compatible. A Y-cable can be used if both a PS/2 mouse and
keyboard are required at the same time.

ACPI

The mother board supports the Advanced Configuration and Power Interface (ACPI) as defined by
the ACPI 2.0 specifications. 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 system 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.
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.
s5: Soft off: Only the RTC section of the CSB and the BMC are running in this state. No
context is saved by the OS or hardware.
IMPORTANT: The system is off only when the AC power cord is
disconnected.
