+ + + + + + 2005 + Scott Rhoades + + + + + + + + + &app; is a utility used to set power consumption and conservation + options. + + + + KDE + KPowersave + power + battery + conservation + + + + + + + + + + KPowersave + + +Introduction + + + + + + Use KPowersave, 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. + + + + Starting KPowersave + + To start KPowersave, open a shell and enter kpowersave + & or select + SystemDesktop Applet + KPowersave from the GNOME or KDE + menu. KPowersave opens in the system + tray. + + + To configure whether KPowersave starts automatically when you log in, + click General Settings then check or uncheck + KPowersave starts automatically on login. Also specify + whether you want KPowersave to ask you about starting automatically if you + exit the application. + + + + + Understanding the KPowersave Icon + + The KPowersave 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. + + + + + + The systemtray applet menu + + + Switch active scheme + + To set the active scheme, right-click the KPowersave icon and select + Set Active Scheme then select the scheme to use. If you + change the active power management scheme with Set Active + Scheme, all components of your system are part of the power + saving effort. A power management scheme includes settings for CPU + frequency scaling (if supported by your computer), throttling, hard disk + control, and system cooling. + + + + + + + + KPowersave menu with entries to switch schemes + + + + + + Starting the YaST Power Management Module + + The YaST Power Management module (currently only available on SUSE) provides + several settings designed to help conserve power. To start the module, + right-click the KPowersave icon and click + Start YaST2 Power Management Module. + Detailed instructions for each setting are available in YaST. + + + + + + + KPowersave menu with entry to start YaST + + + + + + + Starting the YaST Power Management Module requires the root password. + + + + + + Suspending the System + + You can suspend the system at any time by right-clicking the + KPowersave icon and selecting Suspend to Disk, + Suspend to RAM, or + Standby (if standby is supported by the + computer). + + + + + + 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. + + + + + 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. + + + + + + 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. + + + + + + + + KPowersave menu with entries for suspend/standby + + + + + + Deactivating Autosuspend + + If autosuspend is activated for the scheme currently used, + Disable Actions on Inactivity appears in the KPowersave + menu. If you select this option, any actions that are configured to take + place when the computer is inactive do not happen, effectively deactivating + autosuspend. + + + + + + + + KPowersave menu with option "Disable Actions on Inactivity" + + + + + + Setting the CPU Frequency Policy + + To control the amount of power used by the CPU by changing the CPU + frequency policy, right-click the KPowersave icon, click Set CPU + Frequency Policy, and choose one of the available options: + + + + + Performance: Permanently keeps a high CPU frequency for maximum CPU performance. + + + + + Dynamic: Reduces the CPU frequency when the system is idle and adjusts it + dynamically if more CPU power is needed. + + + + + Powersave: Maintains a low CPU frequency to save power. + + + + + + The CPU frequency policy is only available in the menu if it is + supported by your computer. If this option does not appear, it is not + supported by your system. + + + + + + + + KPowersave menu with submenu 'CPU Frequency Policy' + + + + + + + Configuring a Power Management Scheme + + Understanding a Power Management Scheme + + A scheme contains the basic power management configuration that is + used when you use KPowersave with your computer. The number of available + schemes depends on your Powersave configuration. Add or delete schemes with + the YaST Power Management Module. Some common schemes include + the following: + + + + + Performance: Optimized for maximum performance during longer sessions + + + Acoustic: Optimized to let the machine run as quietly as possible + + + Presentation: Optimized for best performance when giving presentations + + + Powersave: Optimized to conserve battery power + + + + To choose a scheme, open the Scheme Settings tab, + click the scheme to use, modify it as desired, then click + OK. + + + + + + + + KPowersave configure dialog (select schemes). + + + + + A scheme controls: + + + + + + Whether the screen saver is permitted to run when the computer is not in use + + + + + How much time is allowed to pass before the screen goes into standby or suspend + mode or is powered off + + + + + Whether the computer automatically goes into Suspend mode after a specified + amount of time + + + + + Whether KPowersave should emit notifications + + + + + + + Procedure to setup a scheme + + + All of these options conserve power by not allowing power-consuming + processes to run. To configure scheme settings, do the following: + + + + Screen Saver + + Right-click the KPowersave icon in the sytem tray. + Select Configure KPowersave. + If the Scheme Settings tab is not already + selected, click Scheme Settings. + Optionally, click Enable Specific Screensaver + Settings. + + + If you do not want the screen saver to consume power when the + system is not in use, click Disable Screen + Saver. + To blank the screen instead of running a specific screen + saver, click Only Blank the Screen. This option is + not available if the + screen saver is disabled. + + + + + + Display Power Management + + To manage the power consumed by the screen, click + Enable Specific Display Power Management. + Specific display power management (DPMS) can also + be disabled by checking Disable Display Power + Management. This setting overwrites the desktop + configuration. + + Select the amount of time that should pass before the screen + goes into standby mode. In standby mode, the screen is blanked, but + continues to receive power. This provides a low level of power + conservation. + Specify the amount of time before the screen is suspended. In + suspend mode, the screen is turned off but enough power is used to + store the current screen information. + Specify the amount of time that should pass before all power + to the screen is turned off. + + + + + + + + KPowersave configure dialog for screen saver and DPMS settings. + + + + + + Setup Autosuspend + + Click Autosuspend if you want + KPowersave to suspend the system automatically if the current desktop + user is inactive for a specified amount of time then use the dialog to + configure specific autosuspend settings. + For example, if you want the system to suspend to disk after 30 + minutes, select the settings to do so. After 30 minutes, all open files + are saved to disk and the computer is suspended. + + + + + + + + KPowersave configure dialog for Autosuspend settings. + + + + + + Setup Sound + + To disable/reenable Notifications for the scheme click + Miscellaneous. Change the Disable Notifications + checkbox ti prevent emit Notifications. You can configure the notifications via + the applet menu by select Configure Notifications.... + + + + + + + + General Settings + + Locking the Screen + + For improved security, you can lock the screen before the computer + goes into suspend or standby mode or when you close the laptop lid. Lock + the screen with a screensaver or with xlock. + + + To lock the screen, click the General Settings tab + then select the settings to use. + + + + + + + + KPowersave configure dialog for general settings. + + + + + + + Creating an Autosuspend Blacklist + + KPowersave 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 + General Settings tab then click Edit General + Blacklist. Use the Autosuspend Blacklist Edit + dialog to add or remove applications from your blacklist. + + + + + + + + KPowersave configure dialog for Autosuspend 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 + use. + + + + + + + + KPowersave dialog to edit Blacklist + + + + + + + + + -- cgit v1.2.3
