The analyzing of energy efficiency in Windows 7 supported by a new command-line option, ENERGY switch to PowerCfg. To generate the Power Management Report, it’s recommended to run the command when system is idle.
How To Perform Energy Efficiency Analysis and Generate Power Management Report in Windows 7 ?
1. Click on Start button -> All Programs -> Accessories, and right-click on Command Prompt then select Run As Administrator to open an elevated command prompt window.
Alternatively, type Cmd in Start Search, and then press Ctrl + Shirt + Enter or right click on Cmd in search result and click Run as Administrator.
2. Type the following command:
PowerCfg -ENERGY
3. The PowerCfg utility will start evaluating energy usage in the system, by running a 60 seconds tracing with the following output (example):
4. After energy efficiency analysis process is completed, an output HTML report file named energy-report.html will be created in the current directory where the command was executed. The report file, which can be view in any web browser, lists the devices and drivers that has energy-related issues such as hindering the full power saving features of the machine, and gives users a snapshot of your system energy consumption over a 60 second period. It also lists if the hardware is capable of S1, S2, S3 or S4 sleep modes.
