Power Management Setup

This option lets you control system power management. The system has various power-saving modes including powering down the hard disk, turning off the video, suspending on RAM, and software power down that allows the system to be automatically resumed by certain events.

Phoenix-AwardBIOS CMOS Setup Utility

Power Management Setup

ACPI Function (Enabled): Use this item to enable or disable the ACPI function.

ACPI Suspend Type (S3(STR)): Use this item to define how your system suspends. In the default, S3 (STR), the suspend mode is a suspend on RAM, i.e., the system shuts down with the exception of a refresh current to the system memory.

Run VGA BIOS if S3 Resume (Auto): This item allows the system to initialize the VGA BIOS from S3 (Suspend on RAM) sleep state.

Power Management (User Define): Use this item to enable or disable a power management scheme. If you enable power management, you can use the items below to set the power management operation.

Video Off Method: This item defines how the video is powered down to save power. This item is set for DPMS (Display Power Management Software) by default.

Suspend Type (Stop Grant): If this item is set to the default Stop Grant, the CPU will go into Idle Mode during power saving power.

Modem Use IRQ (3): If you want an incoming call on a modem to automatically resume the system from a power-saving mode, use this item to specify the interrupt request line (IRQ) that is used by the modem. You might have to connect the fax/modem to the main board Wake On Modem connector for the feature to work.

Suspend Mode (Disabled): This item allows you to enable or disable the suspend mode.

HDD Power Down (Disabled): The IDE hard drive will spin down if it is not accessed within a specified length of time.

Soft-Off by PWR-BTTN(Instant-Off): Under ACPI (Advanced Configuration and Power Management Interface) you can create a software power down. In a software power down, the system can be resumed by Wake Up Alarms. This item lets you install a software power down that is controlled by the power button on your system. If the item is set for Instant-Off, then the power button causes a software power down. If the item is set for Delay four Sec., then you have to hold
