Power Efficiency Diagnostics Report

How to Run a Power Efficiency Diagnostics Report in Windows 7 and Windows 8​

   Information

The Power Efficiency Diagnostics will analyze your system for common energy efficiency and battery life problems, and report any errors, warnings, and informational details found.

This tutorial will show you how to run a power efficiency diagnostics report of your computer in Windows 7 and Windows 8.

   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 an elevated command prompt in Windows 7 or Windows 8.

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)

   Tip

For more information about how to read Powercfg energy reports, you can read the paper "Using PowerCfg to Evaluate System Energy Efficiency" available from the following Microsoft website below as a .docx file.

That's it,

Hello Blissr, and welcome to Seven Forums.

It's an analysis of your PC's power management. There's to much to listed to explain every bit of it here. Most of it is pretty much straight forward for what it says, but did you have anything specific in mind?

 

[BLISSR]

Hi was just wondering anything of concern to be worried about main reason for doing it was to check battery power
thank You

 

[Brink]

I don't see anything that stands out as unusual or would be an issue.

 

[BLISSR]

Thank You

Apologies for creating a Lazarus thread, but this was one of the first links when researching this. I have never run this program on my system (Vista desktop upgraded to Win7), but just noticed something has been running it periodically since Sept. 2022 and saving the xml files in a "Power Efficiency Diagnostics" folder in windows (the oldest report is "energy-report-2022-09-09.xml", the most recent is June 5 this year, file size varies from 21k-74k, anywhere from one to three reports per month).

What is doing this, and why? Are these reports local or being sent somewhere? Can I (should I) disable it?

You might want to run Autoruns and Process Explorer or Process Hacker to narrow down what it is. Don't disable anything in Autoruns you no nothing about. Feel free to open a separate help thread here.

Note: Process Hacker may trip your anti-virus. It's a false positive.
