  32 <para>This module is useful for any computer having a monitor labeled
  33 Energy Star Compliant.  (Energy Star Compliant equipment is equipment
  34 that can be configured to automatically enter a power saving mode when
  35 appropriate, without human intervention.)</para>
  36
  37 <tip><para>Energy Star Compliance can be applied to nearly any
  38 electrical device.  This module, however, does not spin down hard
  39 drives, does not shutdown printers, &etc; These settings only affect
  40 the behavior of your monitor.</para>
  41
  42 <para>For information on shutting down components on a laptop, do not
  43 use this module.  Instead, install kdeutils, and refer to the module
  44 entitled <ulink url="help://kcontrol/powerctrl/index.html">Laptop
  45 Power Control Center</ulink>, for details.</para></tip>
  46
  47 <para>In the case of computer monitors, the computer can control the
  48 monitor, switching it between four states: On, Standby, Suspend, and
  49 Off.</para>
  50
  51 <note><para>The following list of states is a generalization, and you
  52 may find that your monitor will differ from the descriptions
  53 below.</para></note>
  54
  55 <para><quote>ON</quote> is the normal operation of your monitor while you are using
  56 it.</para>
  57
  58 <para><quote>STANDBY</quote> is usually a minor power saving level.
  59 This setting usually involves blanking the screen, and not firing the
  60 electron gun, but keeping the electron gun <quote>energized</quote>
  61 and ready to go. When you need to use the monitor again, the monitor
  62 will come back on very quickly.</para>
  63
  64 <para><quote>SUSPEND</quote> is a very low power mode alternative.
  65 With most monitors the screen is blanked, the electron
  66 gun is shut down and the magnets that control the electron gun are
  67 powered down.  While the power saving is substantial, to reactivate
  68 the monitor may take up to 10-15 seconds.  The computer should always
  69 be able to return the monitor to On or Standby while in suspend
  70 mode.</para>
  71
  72 <para><quote>OFF</quote>, usually means just that.  The computer
  73 monitor is turned off.  This usually means that the computer will not
  74 be able to turn the monitor back on by itself.  Obviously, this keeps
  75 power consumption to a bare minimum (zero).</para>

  80
  81 <para>Using this module is very simple:</para>
  82
  83 <para>If your monitor is Energy Star Compliant, then you should put a
  84 mark in the check box labeled <guilabel>Enable Display Energy
  85 Saving</guilabel>.  This will activate the energy saving
  86 commands. </para>
  87
  88 <para>The next three slider bars, tell the computer how many minutes of
  89 inactivity before automatically switching to a new state.  These numbers
  90 can be adjusted with either the sliders, or the spin boxes.</para>
  91
  92 <note><para>These times are not additive, but all start counting at
  93 zero.</para>
  94
  95 <para>As an example:</para>
  96
  97 <para>If you set the Standby Mode to 10 minutes, the Suspend mode to 20
  98 minutes, and the Power off at 30 minutes, and you stop using your
  99 computer at 9:00, then the monitor will:</para> <para>Enter Standby mode
 100 at 9:10, enter Suspend mode at 9:20, and shut the power off at
 101 9:30.</para></note>
 102
 103 <para>When you are happy with the settings, click
 104 <guibutton>OK</guibutton>.</para>
