Laptop Mode Tools!

RightMark CPU Clock Utility (RMClock) is a small GUI application designed for real-time CPU frequency, throttling and load level monitoring and on-the-fly adjustment of the CPU performance level on supported CPU models via processors power management model-specific registers (MSRs). In automatic management mode it continuously monitors the CPU usage level and dynamically adjusts the CPU frequency, throttle and/or voltage level as needed, realizing the "Performance on Demand" concept. Notice: RMClock is different than CPU RM, those are two very different pieces of software designed to do different things. »

PowerTOP is a Linux tool to diagnose issues with power consumption and power management. In addition to being a diagnostic tool, PowerTOP also has an interactive mode where the user can experiment various power management settings for cases where the Linux distribution has not enabled these settings.

TLP brings you the benefits of advanced power management for Linux without the need to understand every technical detail. TLP comes with a default configuration already optimized for battery life, so you may just install and forget it. Nevertheless TLP is highly customizable to fulfil your specific requirements.

PROGRAM DISCONTINUED (see project's home page)

Jupiter is a light weight power and hardware control applet for Linux. It is designed to improve battery life of a portable Linux computer by integrating with the operating system and changing parameters of the computer based on battery or powered connection.

cbatticon is a lightweight GTK+ system tray application which tells you the state of your battery. If your battery reaches a certain point, it will pop up a message using libnotify.

Processor Hardware Control is a project to allow CPU voltage/frequency changing from userspace.

UPower is an abstraction for enumerating power devices, listening to device events and querying history and statistics. Any application or service on the system can access the org.freedesktop.UPower service via the system message bus. Some operations (such as suspending the system) are restricted using PolicyKit. UPower was once called DeviceKit-power. UPower aims to make a large chunk of HAL redundant, as HAL is officially deprecated.

Boray POWer is a reliable tool that allows you to adjust your PC power plans automatically depending on your computer’s activity. With the aid of a slide bar, one is free to set idle time for system power plan and select any amongst them, ranging from a high performance to a balanced or a power saving one. Also, depending on your requirements, the option to temporarily lock the computer in high performance or power saving mode is readily accessible.

CPUMSR controls frequency, voltage and multiplier settings of supported CPUs.

Faronics Power Save is an effective and reliable energy conservation tool that accurately manages energy consumption throughout ain a multiple workstation environment and significantly cuts down on energy expenditures. Power Save offers flexible options for determining when a computer is inactive (by CPU usage, hard drive usage or by running applications—not just keyboard and mouse movement), and only shuts computers down when they are inactive for a specified amount of time. As well, Power Save can schedule shutdown, start-up, and wake events by day, weekend, weekday, or a specific date. Faronics Power Save provides central reporting, configuration management, deployment, and control across an enterprise via Faronics Core Console. »

SmartPower's “goal” is to hibernate (or sleep) your computer. Use the SmartPower configuration utility to tell SmartPower when the computer should stay on (and turn on) – at all other times your computer will be automatically hibernated.
