Power Management
ACPI modeDescription
G3• Mechanical Off - All devices in the system are turned off completely.  No electrical current is 
running through the system. Except for the real-t ime clock, power consumption is zero. The 
machine can be worked on without damaging the hardware or endangering service 
personnel.
G2/S5• Soft Off - The computer consumes a minima l amount of power. No user mode or system 
mode code is run. It is not safe to disassemble the machine in this state.
G1• Sleeping - The computer consumes a small amount of power, user mode threads are not  being executed, and the system “appears” to be off (from the end user’s perspective, the 
display is off, and so on). It is not safe to disassemble the machine in this state.
G0•  Working - The system dispatches user mode (appl ication) threads and they execute. In this 
state, peripheral devices are having their power state changed dynamically. The user can 
select, through some UI, various performance/po wer characteristics of the system to have 
the software optimize for performance or battery life. The system responds to external events 
in real time. It is not safe to disassemble the machine in this state.

Phoenix SecureCore Setup Utility  
Phoenix SecureCore Setup Utility is a hardware configuration program built into your systems Basic Input/
Output System (BIOS). Since most systems are already properly configured and optimized, there is normally 
no need to run this utility. 
You will need to run this utility under the following conditions: 
• When changing the system configuration including: 
• Setting the system time and date
• Configuring the hard drives
• Specifying the boot device sequence
• Configuring the power management modes
• Setting up system passwords or making other changes to the security setup
• When a configuration error is detected by the system and you are prompted (Run Setup message) to 
make changes to the BIOS settings. 
IMPORTANT: If you repeatedly receive “Run Setup” messages, the RTC battery located on the mainboard 
(RTC1) may be defective. In this case, the system cannot retain configuration values in CMOS. 
Replace the RTC battery with a new one.
NOTE: For ease of reading, Phoenix SecureCore Setup Utility will be simply referred to as “Setup” or “Setup 
Utility” in this Service Guide.
  In the descriptive tables following each of the menu screen illustrations, settings in boldface are the 
default and suggested parameter settings.
The Setup Utility loads the configuration values in a battery-backed nonvolatile memory called CMOS RAM. 
This memory area is not part of the system RAM, which allows configuration data to be retained when power is 
turned off. The values take effect when the system is booted. POST uses these values to configure the 
hardware. If the values and the actual hardware do not agree, POST generates an error message. You must 
run this utility to change the BIOS settings from the default or current configuration.
