1-18 System Overview
The sleep states are defined as follows:
!
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 restores the system state from the disk and resumes 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 chipset and the BMC are running in this state.
AC Link Mode
The AC link mode allows the system to monitor its AC input power so that when the
AC input power is lost and then restored the system will return itself to one of three pre-
selected settings, listed as follows:
!
Power On
!
Last State (Factory Default Setting)
!
Stay Off.
The AC link mode settings can be changed by running the BIOS Setup Utility (F2).
Refer to Chapter 3 "Configuring Your System."
Remote Power-On (Wake ON LAN) Function
The remote power-on function turns on the system power by way of a network or
modem. If the system power is set to OFF, it can be turned on remotely by sending a
specific packet from the main computer to the remote system. This feature can be
enabled or disabled using the BIOS Setup Utility. See Chapter 3.
