Power Management

Power status ACPI mode

G3 • Mechanical Off - All devices in the system are turned off completely. No electrical current is

running through the system. Except for the real-time 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 minimal 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 use r’s perspective, the display is off, and so on). It is not safe to disassemble the machine in this state.

G0 (S0) • Working - The system dispatches user mode (application) 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/power characteristics of the system to have the software optimize for performance or ba ttery li fe. The system responds to external event s in real time. It is not safe to disassemble the machine in this state.

System Utilities

Phoenix SecureCore Setup Utility

Phoenix SecureCore Setup Utility is a hardware configuration program built into your system's 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.
