Save Power with Windows 7 Power Management Diagnostics

Have you been wondering if your laptop or desktop uses more power than it needs to? Well, wonder no more! Windows 7 includes a utility for generating a report of potential energy hogging systems within your computer.

Simply open a Command Prompt window as Administrator, and enter the following command:

powercfg -energy

Windows 7 will take about a minute and a half to analyze power usage and provide an HTML report of possible issues that could be drawing more power than necessary. By default, the report is placed in C:\Windows\System32\energy-report.html, however you can change the output location with the flag -output on the command above, no carats.
