Power Plan Assistant 3.3a
Power Plant Assistant is a free power management software for Windows. It uses system inbuilt power plan as well as its own power saving modes to optimize power usage. Plus, you can use it to turn off display or to lock system directly. It is a very useful software for laptops as well because it helps in increasing the battery backup and also shows various battery related information. In it, you also get the option to change the default battery icon with the new one to get more information including battery level, active power plan, and power source (battery or mains supply).
KAR Energy Software
KAR Energy Software is another free power management software for Windows. The main aim of this software is to reduce the PC power consumption without reducing the performance. This software claims to reduce the power consumption up to 48 %. Not just it reduces the power consumption, but it also increases the system performance and reduces the system startup time. This software uses two main methods to manage the power consumption. The first method is to smartly manage the processor frequency according to the load. The second method uses some advanced features of Intel and AMD processors to bring the power consumption down. The Intel processors have inbuilt EIST and C1E advanced features, but Windows does not support these features natively unless you go through BIOS. However, this software can easily use Intel’s both advanced features directly. EIST and C1E basically enable this software to put PC screen or the whole system in Standby mode. The AMD processor comes with AMD’s own cool and quiet technology that this software uses to reduce power consumption and to increase battery life in case of laptops.
Snap CO2 Saver
Snap CO2 Saver is yet another free power management software for Windows. As its name implies, it helps you reduce the CO2 production by running the system more efficiently. It comes with a small floating interface that shows the information about CO2 savings. An inbuilt search bar is also included in it to search the web. To manage PC power consumption, you can toggle between four available Power Saving modes named as Mild, Medium, Aggressive, and Custom. Let us see the differences between the available power saving modes: Mild Mode: This mode turns off the screen after 30 minutes and hard disk after 60 minutes of inactivity. Medium Mode: It turns off both the hard disk and screen after 30 minutes of inactivity and enters standby mode after 2 hours. It saves twice as much power than the mild mode.
SmartPower
SmartPower is a completely free power management software for Windows. This software helps you significantly reduce the power consumption by Hibernating, Suspending, or Shutting down the PC according to configurable rules. The first thing that you need to configure in it is the selection of Target power state (Hibernate, Suspend, and Shutdown). This software sends the system to the selected power states according to system behavior. In this software, you can configure various system parameters according to which, you want to enable the power state or keep running the system.
