Energy option in Windows 7

Analyze the system for common energy-efficiency and battery life problems. The ENERGY command should be used when the computer is idle and with no open programs or documents. The ENERGY command will generate an HTML report file in the current path. The ENERGY command supports the following optional parameters:

Usage: POWERCFG -ENERGY [-OUTPUT &;;amp;lt;FILENAME&;;amp;gt;] [-XML]
                                    [-DURATION &;;amp;lt;SECONDS&;;amp;gt;]
                   POWERCFG -ENERGY -TRACE [-D &;;amp;lt;FILEPATH&;;amp;gt;]
                                           [-DURATION &;;amp;lt;SECONDS&;;amp;gt;]
            -OUTPUT &;;amp;lt;FILENAME&;;amp;gt;   - Specify the path and filename to store the
                                   energy report HTML file.

                                   analysis. Trace files will be generated in
                                   the current path unless the -D parameter
                                   is specified.
