2-14 Dell OptiPlex E1 Managed PC Reference and Installation Guide3RZHU0DQDJHPHQWFor certain types of monitors and most EIDE hard-disk drives, you can reduce systempower consumption by enabling the power management feature. With PowerManagement enabled, these monitors and drives automatically switch into low-powermode during periods of system inactivity.Power Management can be implemented at three levels—Maximum, Regular, andMinimum. (The different levels apply to the monitor only; hard-disk drive operation isthe same for all three.) The default setting for this category is Disabled.6DYLQJ 0RQLWRU 3RZHUIf you have a Video Electronics Standards Association (VESA ®) Display Power Man-agement Signaling (DPMS)-compliant monitor, enabling the Power Managementcategory reduces monitor power consumption during periods of keyboard and mouseinactivity.&$87,21 &KHFN \RXU PRQLWRU GRFXPHQWDWLRQ WR PDNH VXUH \RX KDYH D'306FRPSOLDQW PRQLWRU EHIRUH \RX HQDEOH WKLV IHDWXUH 2WKHUZLVH \RXULVN GDPDJLQJ WKH PRQLWRUNOTE: The power management feature monitors activity of a mouse connected to thePS/2-compatible mouse port.By setting Power Management to Maximum, Regular, or Minimum, you can set pre-defined time-out periods (see Table 2-2) for the two successive monitor shutdownstages,standby andoff.NOTE: Each monitor manufacturer defines the details of the shutdown stages for itsown 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.From either shutdown stage, you can return full power to the monitor in one of the fol-lowing ways:á For most DPMS-compliant monitors, any subsequent activity—including movingthe mouse—should return full power to the monitor.á A few DPMS-compliant monitors require that you turn monitor power off andthen on again to return to full power.Check your monitor documentation for information on how your monitor is designedto operate.6DYLQJ (,'( +DUG'LVN 'ULYH 3RZHUFor most systems, enabling Power Management at any level causes EIDE hard-diskdrives to switch to low-power mode after about 20 minutes of system inactivity (seeTable 2-2).
