How to Run a Power Efficiency Diagnostics Report in Windows 7

Information

This will show you how to run a power efficiency diagnostics report of your computer in Windows 7. This report will analyze your system for common energy efficiency and battery life problems, and report any errors, warnings, and informational details found.

Warning

You should run this report when your computer is idle and with no open programs or documents for the best results.

Here's How:

1. Open a elevated command prompt.

2. In the elevated command prompt, copy and paste the command below and press Enter. (see screenshot below)
NOTE: This will take 60 seconds to run by default. When done it will give you a quick report of any poroblems found and place a detailed Energy_Report.html file on your desktop.

powercfg -energy -output %USERPROFILE%\Desktop\Energy_Report.html

Note

You could also change the command to be able to use your own location for where you want the Energy_Report.html file to be placed (outputted) at.

powercfg -energy -output "C:\Full Path\Energy_Report.html"

3. Double click on the Energy_Report.html file on your desktop to open and see the power efficiency diagnostics report in Internet Explorer. (See screenshot below)

4. This is a copy of my power efficiency diagnostics report in Internet Explorer as an example of what you can see. (See screenshots below)

That's it,

Hello Dinesh.

Yeah, the -energy extension is a nice addition to the powercfg command in Windows 7. Very nice.

Is this option Available for Windows Vista?

Brink · 09-15-2010

Hello Hariharan,

Sorry, but it's not available in Vista. It's a new feature in Windows 7.

OK now I have the report, but what do I do with it in order to correct the seeming USB issues? Please be very specific, as I require detailed instructions. Thanks in advance.

Hello RJl24,

If you are referring to your issue that you posted at your thread below, then this report has nothing to do with that.

Something went amiss

RJL24 · 11-24-2010

Actually, that issue of something went amiss

Something went amiss

has been resolved, please see the thread.

This posting and report is something I did when analyzing the amiss problem, and discovered a new diagnostic tool.

I redid the analysis today.

In effect the posting I made above regarding the report is relevant to the report and has nothing to do with the previous posting about the haywire behavior of my computer which seems strongly to be linked to a defective USB hub.

But thanks for noting my previous post anyway.

This report basically just lets you know what the USB device's power plan options are set as. I did not notice any issues in your report that were just normal for these devices though.

Thanks for your analysis. if it ain't broke: don't fix it.

Cheers,
RJL
