If you want to diagnose energy consumption by a computer. Then use the following steps, type ‘cmd’ in the search field of the Start menu and then click the file ‘cmd.exe’ with the right mouse button and select the context command ‘Run as administrator’. After confirming the User Account Control prompt with ‘Yes’, type the command ‘powercfg/ energy’ in the window and press the [Enter] key. Windows will now audit the system behaviour for 60 seconds. In the meantime, you can go on working. Subsequently, the result is saved by default as a fi le with the title ‘energy report.html’ in the currently open folder which you see in the command prompt. Optionally, you can also define a custom target file with the parameter ‘-output’.
