<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>
|
|
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.

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

scheme. When creating a scheme blacklist, you can import the general

blacklist or create a specific blacklist for that scheme. A scheme-specific

blacklist overrides the general blacklist when that scheme is in
