C2SEA/C2SEE User’s Manual

1-3 Recovery from AC Power Loss

BIOS provides a setting for you to determine how the system will respond when AC power is lost and then restored to the system. You can choose for the system to remain powered off (in which case you must hit the power switch to turn it back on) or for it to automatically return to a power on state. See the Power Lost Control setting in the BIOS chapter of this manual to change this setting. The default set- ting is Power-Off.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the C2SEA/C2SEE. The motherboard has an onboard System Hardware Monitor chip that supports PC health monitoring.

The onboard voltage monitor will scan the Onboard Voltage Monitors for the CPU Core, +1.8V, +3.3V, +5V standby, +5V, Vbat and ±12V continuously. Once a voltage becomes unstable, it will give a warning or send an error message to the screen. Users can adjust the voltage thresholds to define the sensitivity of the voltage moni- tor by using SuperO Doctor III.

1-5 ACPI Features

ACPI stands for Advanced Configuration and Power Interface. The ACPI specifica- tion defines a flexible and abstract hardware interface that provides a standard to integrate power management features throughout a PC system, including its hardware, operating system and application software. This enables the system to automatically turn on and off peripherals such as CD-ROMs, network cards, hard disk drives and printers. This also includes consumer devices connected to the PC such as VCRs, TVs, telephones and stereos.

In addition to enabling operating system-directed power management, ACPI pro- vides a generic system event mechanism for Plug and Play and an operating- sys- tem-independent interface for configuration control. ACPI leverages the Plug and Play BIOS data structures while providing a processor architecture-independent implementation that is compatible with Windows 2000, Windows XP, Windows 2003, Windows 2003 Servers.

Enhanced Power Management

The onboard ICH10 chip provides advanced power management functions that will greatly improve the performance of various low-power (suspend) states and en- hance clock control. A hardware-based component provides software-independent thermal management that is compatible with the ACPI Revision 3.0a.
