Saving Eide Hard-Disk Drive Power; Sound; Nic; Mouse - Dell OptiPlex GXi Reference And Installation Manual

By setting
POWER MANAGEMENT
or , you can set predefined time-out periods (see
MINIMUM
Table 2-2) 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
monitor, see the documentation that came with the
monitor.
From either shutdown stage, you can return full power to
the monitor in one of the following ways:
•
For most DPMS-compliant monitors, any subse-
quent activity—including moving the mouse—
should return full power to the monitor.
•
A few DPMS-compliant monitors require that you
turn monitor power off and then on again to return to
full power.
Check your monitor documentation for information on
how your monitor is designed to operate.

Saving EIDE Hard-Disk Drive Power

For most systems, enabling
level causes EIDE hard-disk drives to switch to low-
power mode after about 20 minutes of system inactivity.
NOTES: Not all EIDE hard-disk drives support this fea-
ture. Enabling this feature for drives that do not support
it may cause the EIDE drive to become inoperable until
the computer is restarted and the
category is disabled.
However, all EIDE drives shipped with your original sys-
tem support this feature. (For more information on
Energy Star systems, see "Energy Star Compliance" in
Chapter 1.)
In low-power mode, the disks inside the drive stop spin-
ning. They remain idle until the next drive access, which
causes them to start spinning again. (Because the disks
take a few seconds to regain full speed, you may notice a
slight delay when you next access the hard-disk drive.)
When

tem is turned on.

If you set the serial port to
containing a port configured to the same designation, the
system automatically remaps the built-in port to the next
available port designation that shares the same IRQ setting:
•
COM1 (input/output [I/O] address 3F8h), which
shares IRQ4 with COM3, is remapped to COM3
(I/O address 3E8h).
•
Likewise, COM2 (I/O address 2F8h), which shares
IRQ3 with COM4, is remapped to COM4 (I/O
address 2E8h).
