System Power: With this option, you can select On if you want the computer to remain on, or Off if you want the computer to shut down. Processor Speed: With this option, you can set your microprocessor to run at 1, 10, 25, or 50 percent of its internal clock speed, or you can disable the microprocessor entirely. Any computer activity returns the microprocessor to full speed. Display: With this option, you can select one of the following reduced-power states or the off state: - Standby: In this mode, the screen is blanked, but the screen image is restored immediately when any activity is detected. - Suspend: In this mode, the monitor uses less power than in Standby mode. The screen is blanked, but the screen image is restored within a few seconds after any activity is detected. - Off: In this mode, the monitor power is turned off. To restore power to the monitor, you must press the monitor power switch. On some monitors, you might have to press the power switch twice. Hard Disk Drive: With this option, you can enable the hard disk drive to "spin down" (shut down the drive motor) after about 20 minutes of inactivity on the drive. When you attempt to read from or write to the hard disk, the spindle starts back up within a few seconds. This feature can be activated in PC models with EIDE hard disk drives, but not in models with SCSI hard disk drives. (In models with SCSI hard disk drives, the feature is set to Enabled by default, but it is not operational.) Setting Automatic Power Management Features: To set these features, complete the following steps. 1. Start the Configuration/Setup Utility program (see "Starting the Configuration/Setup Utility Program" on page 38). 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. 54 Using Your Personal Computer
