<para>This module is useful for any computer having a monitor labeled
|
||
|
|
Energy Star Compliant. (Energy Star Compliant equipment is equipment
|
||
|
|
that can be configured to automatically enter a power saving mode when
|
||
|
|
appropriate, without human intervention.)</para>
|
||
|
|
|
||
|
|
<tip><para>Energy Star Compliance can be applied to nearly any
|
||
|
|
electrical device. This module, however, does not spin down hard
|
||
|
|
drives, does not shutdown printers, &etc; These settings only affect
|
||
|
|
the behavior of your monitor.</para>
|
||
|
|
|
||
|
|
<para>For information on shutting down components on a laptop, do not
|
||
|
|
use this module. Instead, install kdeutils, and refer to the module
|
||
|
|
entitled <ulink url="help://kcontrol/powerctrl/index.html">Laptop
|
||
|
|
Power Control Center</ulink>, for details.</para></tip>
|
||
|
|

|
|
<para>In the case of computer monitors, the computer can control the
|
||
|
|
monitor, switching it between four states: On, Standby, Suspend, and
|
||
|
|
Off.</para>
|
||
|
|
|
||
|
|
<note><para>The following list of states is a generalization, and you
|
||
|
|
may find that your monitor will differ from the descriptions
|
||
|
|
below.</para></note>
|
||
|
|
|
||
|
|
<para><quote>ON</quote> is the normal operation of your monitor while you are using
|
||
|
|
it.</para>
|
||
|
|
|
||
|
|
<para><quote>STANDBY</quote> is usually a minor power saving level.
|
||
|
|
This setting usually involves blanking the screen, and not firing the
|
||
|
|
electron gun, but keeping the electron gun <quote>energized</quote>
|
||
|
|
and ready to go. When you need to use the monitor again, the monitor
|
||
|
|
will come back on very quickly.</para>
|
||
|
|
|
||
|
|
<para><quote>SUSPEND</quote> is a very low power mode alternative.
|
||
|
|
With most monitors the screen is blanked, the electron
|
||
|
|
gun is shut down and the magnets that control the electron gun are
|
||
|
|
powered down. While the power saving is substantial, to reactivate
|
||
|
|
the monitor may take up to 10-15 seconds. The computer should always
|
||
|
|
be able to return the monitor to On or Standby while in suspend
|
||
|
|
mode.</para>
|
||
|
|
|
||
|
|
<para><quote>OFF</quote>, usually means just that. The computer
|
||
|
|
monitor is turned off. This usually means that the computer will not
|
||
|
|
be able to turn the monitor back on by itself. Obviously, this keeps
|
||
|
|
power consumption to a bare minimum (zero).</para>

<para>Using this module is very simple:</para>
|
||
|
|
|
||
|
|
<para>If your monitor is Energy Star Compliant, then you should put a
|
||
|
|
mark in the check box labeled <guilabel>Enable Display Energy
|
||
|
|
Saving</guilabel>. This will activate the energy saving
|
||
|
|
commands. </para>
|
||
|
|
|
||
|
|
<para>The next three slider bars, tell the computer how many minutes of
|
||
|
|
inactivity before automatically switching to a new state. These numbers
|
||
|
|
can be adjusted with either the sliders, or the spin boxes.</para>
|
||
|
|
|
||
|
|
<note><para>These times are not additive, but all start counting at
|
||
|
|
zero.</para>
|
||
|
|
|
||
|
|
<para>As an example:</para>
|
||
|
|
|
||
|
|
<para>If you set the Standby Mode to 10 minutes, the Suspend mode to 20
|
||
|
|
minutes, and the Power off at 30 minutes, and you stop using your
|
||
|
|
computer at 9:00, then the monitor will:</para> <para>Enter Standby mode
|
||
|
|
at 9:10, enter Suspend mode at 9:20, and shut the power off at
|
||
|
|
9:30.</para></note>
