Power Management Setup

The Power Management Setup option sets the system’s power saving functions.

ACPI function

You can enable or Disable Advanced Configuration Power Interface features. [For more information see your motherboards documentation]

Power Management

This category allows you to select the type (or degree) of power saving and is directly related to the following modes: Doze; Standby; Suspend; HDD Power Down.

Disabled	Global Power Management will be disabled. (No power management. Disables all 4 modes.)
Min. Power Saving	Minimum power management. Pre-defined timer values are used such are used such that all timers are in their MAX value.
Max. Power Saving	Pre-defined timer values are used such that all timers MIN value. Maximum power management only available for SL CPU’s.
User Defined	Allows you to set each mode individually.

PM Control by APM

When enabled, an Advanced Power Management device will be activated to enhance the Max. Power Saving Mode and stop the CPU internal clock.

No	System BIOS will ignore APM when power managing the system
Yes	System BIOS will wait for APM’s prompt before it enter any PM mode e.g. Doze, Standby, or Suspend

Video Off Method

When you are using the Green Monitor with your PC system, there are three modes selectable in this field to save the power energy.

Blank Screen

H-SYNC and V-SYNC signals are still active when the system turns into green mode, only the RGB signals are disabled. The power of the monitor remains ON, but you can see no display on the screen.

V/H SYNC+Blank

H-SYNC, V-SYNC and RGB signals are all disabled to blank the screen(ports and write blanks to the video buffer). Before you can select this option, make sure whether your display card has special design on the H-SYNC and V-SYNC signal. Such VGA card display may not be recovered when we blank the screen.

DMPS

Initial Display Power Management Signaling. Beside the H-SYNC, V-SYNC and RGB signals, the monitor will be power off when computer enters the Green mode. So not only the screen will be blank off, the power of the monitor will be turned off to save the energy. This option is the recommended one you have the Green monitor connected to your PC system.

Video off After

When enabled, this feature allows the VGA adapter to operate in power saving mode.

N/A	Monitor will remain on during power saving modes.
Suspend	Monitor blanked when the system enters Standby mode.
Standby	Monitor blanked when the system enters Standby mode.
Doze	Monitor blanked when the system enters any power saving mode.

Modem Use IRQ

If your mainboard has the ACPI (Advanced Configuration Power Interface) feature designed on board and it will “wakeup” automatically when it detects the incoming modem Ring-in signal. Before you can use the Ring-in signal to wakeup your PC, you have to install a modem (some systems only support external modems for this function) to your PC and tell the PC system which serial port connects to the modem by selecting the IRQ in this field. (officially, COM1 uses IRQ4, and COM2 uses IRQ3)

[For more information see your motherboards documentation]

Doze Mode

Doze mode is the most limited power saving mode, The PC will be inactive (the CPU clock will run at slower speed while all other devices still operate at full speed) after the time period which you have selected in this field.

Standby Mode

Standby mode is the intermediate power saving mode, the PC system will be inactive (the HDD and the video would be shut off while all other devices still operate at full speed) after the time period which you have selected in this field.

Suspend Mode

Suspend Mode is the maximum power saving mode, The PC will be inactive (all devices expect the CPU will be shut off) after the time period which you have selected in this field.

HDD Power Down

When enabled and after the set time of system inactivity, the hard disk drive (it should be a power saving mode HDD) will be powered down (motor off) while all other devices remain active.

Note:

When HDD is in power saving mode, any access to the HDD will wake the HDD up.

Wake Up Events In Doze & Standby

The specified event’s activity causes the PM Timers to be reloaded (i.e. the Power Management Unit (PMU) monitors the specified activities as PM events).

Power Down & Resume Events (IRQ3~15)

These are I/O events whose occurrence can prevent the system from entering a power saving mode can awaken the system from such a mode. In effect, the system remains alert for anything which occurs to a device which is configured as On, even when the system is in a power down mode. When an I/O device wants to gain the attention of the OS, it signals this by causing an IRQ to occur. When the OS is ready to respond to the request, it interrupts itself and performs the service. When set off, activity will neither prevent the system from going into a power management mode nor awaken it.

Reload Global Timer Events

When enabled, an event occurring on each device listed under your “Reload Global Timer Events” restarts the global time for Standby mode.

i.e. you can enable;

IRQ [3-7,9-15], NMI

Primary IDE 0

Primary IDE 1

Secondary IDE 0

Secondary IDE 1

Floppy Disk

Serial Port

Parallel Port

IRQ x Break Suspend

When enabled, the device which occupies the IRQ x can wake the system.

(In most system’s IRQ8)

VGA Active Monitor

When the PC enters the Green mode, the system will keep scanning the status of the monitor. You may use this field to select whether you are going to have the monitor get into Green mode or not:

Enabled : The screen display will not be off (or powered off) when there is the video signal sending from VGA card to monitor.

Disabled : The screen display will be blank off (or powered off) no matter whether there is the video signal sending from VGA card to monitor or not.

Soft-Off by PWR-BTTN

Instant-off or Delay 4sec (ATX power supply only)

Instant-off: When push the power button, the system power will be off immediately.

Delay 4 sec: When push the power button, it will enter suspend mode. You need to push the power button and hold for 4 seconds to turn off the power. [For more information read your motherboard’s user manual.]

CPUFAN Off In Suspend

This section allows user to controls the function of the CPU cooling fan. When “Enabled” is selected, the CPU cooling fan will stop (cooling fan must be connected to the motherboard’s “CPU fan” power connector) in Suspend mode to decrease the system power consumption and noise. When “Disabled” the CPU cooling fan keeps on working when the system is in Suspend mode.

Resume by Ring or LAN (Modem Ring Resume)

When “Enabled”, you can resume the system from Sleep or Suspend mode (if ATX power supply, system can be turned on) by using a Modem Ring-in or a LAN signal. [For more information please read your motherboard’s user manual.]

Note:

In some systems “Modem Ring Resume” function only works when the system is turned off in Windows mode, and Doze mode will not function.

Resume by Alarm (RTC Alarm Resume)

You can select the date and time which you want to resume the system from Sleep or Suspend mode.(If power supply ATX, automatically power on that date & time you were selected) [For more information please read your motherboard’s user manual.]

Note:

In some systems “RTC (Real Time Clock) Resume” function only works when the system is turned off in Windows mode, and Doze mode will not function.

Throttle Duty Cycle

Over heat will cause to damage the CPU. Use this option to select the “Throttling Speed” to protect your CPU when over heating. [For more information please read your motherboard’s user manual.]
