IBM PC/IBM IntelliStation - Power management
Applicable to: World-Wide
Power Management:
Power management reduces the power consumption of certain components of the computer such as the system power supply, processor, hard disk drives, and some monitors. Advanced Power Management and Rapid Resume Manager are features of some personal computers.
Automatic Configuration and Power Interface (ACPI) BIOS Mode:
When ACPI BIOS mode is enabled, the operating system is allowed to control the power management features of the computer and the setting for Advanced Power Management (APM) BIOS mode are ignored. Not all operating systems support ACPI BIOS mode. ACPI BIOS mode can be enabled or disabled in Setup under Power Management.
Advanced Power Management:
Energy-saving settings can be viewed and changed by using the Advanced Power Management menu in the Configuration/Setup Utility program.

Automatic Hardware Power Management Features:
Automatic Hardware Power Management can reduce the power states of the computer, processor, and monitor (if monitor supports DPMS) if they are inactive for a predetermined length of time.
There are three levels of specified time that the computer must be inactive before the power management options that are selected take effect. Select the amount of time that is offered within each level.
Level 1: Set time from 5 minutes to 4 hours.
Level 2: Set time from 10 minutes to 5 hours.
Level 3: Set time from 15 minutes to 6 hours.
At each level, you can define the amount of energy savings by specifying values for the following options:
System Power:
- Select On for the computer to remain on.
- Select Off for the computer to shut down.
Processor Speed:
Set the microprocessor to be disabled, or to run at 1, 10, 25, or 50 percent of its internal clock speed.
Display:
Set display to be disabled or to be reduced at these power states:
- Standby: Screen is blank, but can be restored immediately when any activity is detected.
- Suspend: Monitor uses less power than in Standby mode. Screen image is restored after a few seconds when any activity is detected.
- Off: Monitor power is off. Press Monitor power button to restore power. On some monitors, you might have to depress the power button twice.
Setting Automatic Hardware Power Management Features:
1. Start the Configuration/Setup Utility program (see Setup Utility Program).
2. Select Advanced Power Management from the Configuration/Setup Utility program menu.
3. Be sure APM BIOS Mode is set to Enabled. If it is not, press Left Arrow or Right Arrow to change the setting.
4. Select Automatic Hardware Power Management.
5. Set Automatic Hardware Power Management to Enabled.
6. Select values for the three levels of power management (system power, processor speed, and display), as necessary.
7. Set Hard Disk to Enabled or Disabled.

Note: |
8. Press Esc twice to return to the Configuration/Setup Utility program menu.
9. Before you exit from the program, select Save Settings from the Configuration/Setup Utility program menu.
10. To exit from the Configuration/Setup Utility program, press Esc and follow the instructions on the screen.
Automatic Power-On Features:
The Automatic Power-On features within the Advanced Power Management menu allow you to enable and disable features that turn the computer on automatically.
Serial Port Ring Detect:
With this feature set to Enabled and an external modem connected to the serial port, the computer will turn on automatically when a ring is detected on the modem.
Modem Ring Detect:
With this feature set to Enabled , the computer will turn on automatically when a ring is detected on the internal modem.
Wake Up on Alarm:
You can specify a date and time at which the computer will be turned on automatically. This can be either a single event or a daily event.
Wake on LAN:
If the computer has a properly configured token-ring or Ethernet LAN adapter card that is Wake on LAN-enabled and there is remote network management software, you can use the IBM-developed Wake on LAN feature. When you set Wake on LAN to Enabled , the computer will turn on when it receives a specific signal from another computer on the local area network (LAN). For Further information, see Wake on LAN.
Rapid Resume Manager:
Some personal computers come with built-in energy-saving capabilities. Rapid Resume Manager reduces the power consumption of the computer. The following are features of Rapid Resume Manager:
Rapid Resume
Standby
Scheduler
Wake Up on Ring
Rapid Resume:
With Rapid Resume activated, the computer saves its current state when you power it off with the power switch. Rapid Resume retains all current settings, remembers which programs were active, and saves the position and size of windows and other objects on the screen. When the computer is restarted (with the power-on switch, the Scheduler, or Wake-Up on Ring), it quickly returns to full-power operation in exactly the same state. The programs that were being used will reappear in the state they were in when you suspended operation of the computer.
Running Rapid Resume Manager:
To select and activate, deactivate, or change Rapid Resume Manager, do the following.
1. From Program Manager, select IBM Management Plus.
2. Select Rapid Resume Manager.
3. View or change settings.
4. Follow the instructions on the screen.
Standby:
When the Standby feature is enabled, it initiates reduced power modes for the display, microprocessor, and hard disk drive after a specified period of inactivity. The default setting for automatically initiating standby is 20 minutes. The display is blanked and the hard disk drive "spins down' (enters a reduced-power state). Any use of the keyboard, mouse, or hard disk drive causes the computer to exit standby and return to full-power operation. For example, if 40 minutes is selected as the specified period, the computer goes into standby state if the mouse, keyboard, or microprocessor is not active for more than 40 minutes.
To select and activate, deactivate, or change the Standby feature, see Running Rapid Resume Manager.
Scheduler:
Use the Scheduler to set a time for the computer to do the following:
Start a program
Display a message
Power-off the computer
If the computer will not already be powered-on when it is time to start a program or display a message, a setting can be selected to power-on the computer at the appropriate time.
To select and activate, deactivate, or change the Scheduler feature, see Running Rapid Resume Manager.
Wake Up on Ring:
You can select settings so that, if the modems receives a call the computer is in the suspend state, the computer "wakes up" on the first ring; that is, it returns to full-power.
To select the Wake Up on Ring settings, feature, see Running Rapid Resume Manager.
