Dell OptiPlex E1 - Manual (Page 22)

Report Keyboard Errors
Report Keyboard Errors enables or disables reporting of keyboard errors during the POST, which is a series of tests that the
system performs on the hardware each time you turn on the system or press the reset button.
This category is useful when applied to self-starting servers or host systems that have no permanently attached keyboard. In these
situations, selecting Do Not Report suppresses all error messages relating to the keyboard or to the keyboard controller during
POST. This option does not affect the operation of the keyboard itself if a keyboard is attached to the computer.
Auto Power On
Auto Power On allows you to set the time and days of the week to turn on the computer system automatically. You can set Auto
Power On to turn on the system either every day or every Monday through Friday.
NOTE: This feature does not work if you turn off your system using a power strip or surge protector.
Time is kept in a 24-hour format (hours:minutes). To change the start-up time, press the right-arrow key to increase the number in
the highlighted field or press the left-arrow key to decrease the number. If you prefer, you can type numbers in both fields.
The default for Auto Power On is Disabled.
Wakeup On LAN
Wakeup On LAN determines whether the Wakeup On LAN feature is set to On or Off. You must reboot your system before a
change takes effect.
Power Management
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 Management 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 default setting for this category is Disabled.
Saving Monitor Power
If you have a Video Electronics Standards Association (VESA ®) Display Power Management Signaling (DPMS)-compliant monitor,
enabling the Power Management category reduces monitor power consumption during periods of keyboard and mouse inactivity.
CAUTION: Check your monitor documentation to make sure you have a DPMS-compliant monitor before you
enable this feature. Otherwise, you risk damaging the monitor.
NOTE: The power management feature monitors activity of a mouse connected to the PS/2-compatible mouse port.
By setting Power Management to Maximum, Regular, or Minimum, you can set predefined time-out periods (see Table 2-2) for the
two successive monitor shutdown stages, standby and off.
