Cutting power costs with KPowersave
KPowersave gives KDE users a single easy interface for configuring power management settings.
Modern hardware comes with
any number of power-saving
options. KPowersave  provides
a simple interface for managing
these power options in Linux.
KPowersave requires an up-to-date KDE
version. You’ll also need a few helper applications.
The Hardware Abstraction
Layer (HAL)  facilitates access to peripherals.
The version on your machine
must be 0.5.4 or later. D-Bus, a technology
that programs use to communicate
on the X Window System , should be
version 0.33 or newer, and you also need
Powersave  0.10.15 or newer.
