8.5.9 Power Management

The System > Power Management module helps you work with saving energy technolo-
gies. It is especially important on laptops to extend their operational time. Find detailed
information about using this module in Section 28.6, "The YaST Power Management
Module" (page 524).
8.5.10 Powertweak Configuration
Powertweak is a SUSE Linux utility for tweaking your system to peak performance by
tuning some kernel and hardware configurations. It should be used only by advanced
users. After starting it with System > Powertweak, it detects your system settings and
lists them in tree form in the left frame of the module. You can also use Search to find
a configuration variable. Select the option to tweak to display it on the screen along
with its directory and settings. To save the settings, click Finish then confirm it by
clicking OK.

8.5.11 Profile Manager

Create, manage, and switch among system configurations with System > Profile Man-
agement, the YaST system configuration profile management (SCPM) module. This
is especially useful for mobile computers that are used in different locations (in different
networks) and by different users. Nevertheless, this feature is useful even for stationary
machines, because it enables the use of various hardware components or test configura-
tions.
8.5.12 System Services (Runlevel)
Configure runlevels and the services that start in them with System > System Services
(Runlevel). For more information about the runlevels in SUSE Linux Enterprise and a
description of the YaST runlevel editor, refer to Section 20.2.3, "Configuring System
Services (Runlevel) with YaST" (page 398).
