<para>Use TDEPowersave, the KDE front-end to powersave, to control power
management and monitor your laptop battery strength. For example, you can
configure the screen on your laptop to turn off if the computer is not used
for a specified amount of time, extending battery life.
</para>
<sect1 id="starting">
<title>Starting TDEPowersave</title>
<para>To start TDEPowersave, open a shell and enter <command>tdepowersave
&</command> or select
<menuchoice><guimenu>System</guimenu><guimenu>Desktop Applet</guimenu>
<guimenu>TDEPowersave</guimenu></menuchoice> from the GNOME or KDE
menu. TDEPowersave opens in the system
tray.
</para>
<para>To configure whether TDEPowersave starts automatically when you log in,
click <guimenu>General Settings</guimenu> then check or uncheck
<guimenu>TDEPowersave starts automatically on login</guimenu>. Also specify
whether you want TDEPowersave to ask you about starting automatically if you
exit the application.
</para>
</sect1>
<sect1 id="understandingicon">
<title>Understanding the TDEPowersave Icon</title>
<para>
The TDEPowersave icon looks like a power plug next to a battery strength
indicator. The icon shows the current battery strength and whether the
computer is powered by the battery or the power supply. When the battery
power is low, the background of the icon flashes, orange for Warning
and red for Low or Critical. If you leave the mouse cursor over the icon, a
message shows whether the computer is plugged in or using the battery, the
current charge level of the battery, and, if the computer is running on
battery power, the approximate amount of time left before the battery power
runs out.

change the active power management scheme with <guimenu>Set Active

saving effort. A power management scheme includes settings for CPU
frequency scaling (if supported by your computer), throttling, hard disk
control, and system cooling.

You can suspend the system at any time by right-clicking the

<guimenu>Standby</guimenu> (if standby is supported by the

Suspend to Disk saves all open data to disk before the computer is suspended.
This protects your data if power is cut off or the battery dies.

<para>
Suspend to RAM saves the data to RAM, making data retrieval faster when
the computer is brought out of suspend mode.

Standby deactivates the monitor while maintaining power to the system so
that any open data remains in RAM.
</para>

<para>
The selections that are available depend on which methods have been activated
in YaST by the administrator and whether standby is supported by your
computer. The choice you make should depend on the likelihood of the
computer losing power.

<title>Understanding a Power Management Scheme</title>
<para>
A scheme contains the basic power management configuration that is
used when you use TDEPowersave with your computer. The number of available

the YaST Power Management Module. Some common schemes include
the following:
</para>

TDEPowersave provides an autosuspend blacklist. The blacklist prevents
the system from being suspended if one of the listed applications is
running. For example, you probably do not want your laptop to go into
suspend mode while you are watching a DVD, just because you have not
pressed a key for ten minutes. To edit the blacklist, click the
<guimenu>General Settings</guimenu> tab then click <guimenu>Edit General
Blacklist</guimenu>. Use the <guimenu>Autosuspend Blacklist Edit</guimenu>
dialog to add or remove applications from your blacklist.

You can also use this setting to create and edit blacklists for each

blacklist or create a specific blacklist for that scheme. A scheme-specific
blacklist overrides the general blacklist when that scheme is in
use.
