For certain types of monitors and most EIDE hard-disk drives, you can reduce system power consumption by enabling the power management feature. With Power Man- agement enabled, these monitors and drives automatically switch into low-power mode during periods of system inactivity.

Power Management can be implemented at three levels—Maximum, Regular, and Minimum. (The different levels apply to the monitor only; hard-disk drive operation is the same for all three.) The feature can also be set to Disabled.

If you have a Video Electronics Standards Association (VESA® ) Display Power Man- agement Signaling (DPMS)-compliant monitor, enabling Power Management reduces monitor power consumption during periods of keyboard and mouse inactivity.

NOTES: Some 3D graphics cards do not support DPMS. Refer to the documentation for your particular 3D graphics card for information.

The power management feature monitors activity of a mouse connected to the Personal System/2 (PS/2)-compatible mouse port.

By setting Power Management to Maximum, Regular, or Minimum, you can set pre- defined time-out periods (see Table 3-2) for the two successive monitor shutdown stages, standby and off.

NOTE: Each monitor manufacturer defines the details of the shutdown stages for its own monitors. But in all cases, power consumption decreases with each stage from “on” (full power) to “standby” (reduced power; the display image usually disappears) to “off” (where power consumption is minimal). To define these stages for your mon- itor, see the documentation that came with the monitor.

For most DPMS-compliant monitors, any subsequent activity—including moving the mouse—returns full power to the monitor.

Check your monitor documentation for information on how your monitor is designed to operate.
