Windows 10: Create Power Efficiency Diagnostics Report in Windows 10

How to: Create Power Efficiency Diagnostics Report in Windows 10

How to Create a Power Efficiency Diagnostics Report in Windows 10


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 PC in Windows 10.

You must be signed in as an administrator to be able to run a power efficiency diagnostics report.

*note For the best results, you should run the power efficiency diagnostics report when the PC is idle and with no open programs or documents.



Here's How:

1. Open an elevated command prompt.

2. In the elevated command prompt, copy and paste the command below, and press Enter. (see screenshot below)

Code:

3. Double click/tap on the Power_Efficiency_Diagnostics_Report.html file on your desktop to open and see the power efficiency diagnostics report in your default web browser (ex: Internet Explorer).

4. Here is a copy of my power efficiency diagnostics report in Internet Explorer as an example of what you will 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.

Power Efficiency Diagnostics Report

Hi,

I got this report using powercfg command. And there was update installed recently for Windows 10 and defender. these were all the changes.

Could you please provide me countermeasures for the errors and warnings on that report I posted?

Platform Power Management Capabilities:Supported Sleep States

Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer
to resume working quickly. Very few platforms support the S1 or S2 Sleep states.

S1 Sleep Supported
false

S2 Sleep Supported
false

S3 Sleep Supported
true

S4 Sleep Supported
true

Platform Power Management Capabilities:Connected Standby Support

Connected standby allows the computer to enter a low-power mode in which it is always on and connected. If supported, connected standby is used instead of system sleep states.

Connected Standby Supported
false

Platform Power Management Capabilities:Adaptive Display Brightness is supported.

This computer enables Windows to automatically control the brightness of the integrated display.

Also here is the properties detail tab. Noticed creation date vs modified date, it seems to be an older one:

 

Hey Cliff,

My folder was still empty even after running the perfmon /report command. Is your Windows 10 a clean install, or did you upgrade to Windows 10?

 

Clean install and absolutely no OEM bulkware(just the needed drivers). One thing I do run pretty often as part of my maintenance, when cleaning up, is winsat formal with a reboot to have windows check and set it's defaults for my SSD & HDD, but that doesn't have anything to do with power efficiency.
Maybe Samsung Magician created it for RAPID. I have RAPID on, Fast Startup on and both disks set to turn off write cache buffer flushing.

 

It'll be interesting to find out what is saving there.

 

There is nothing that says what created it in the folder properties either...

 

Something of interest in Task Manager Scheduler in Computer Management, the triggers tab is empty though, and everything is like a normal system task should be set up:

 

Here is the tasks XML if that helps you:

I haven't found anything yet that saves to that location. It looks like it's going to be a mystery for a while.

 

Like you I have one created most (but not every) day. Mine go back to 19th December when I last did clean install and are not generated at any particular time of day.

Do you have a laptop? Perhaps it is normal. I've turned on history in task scheduler and will let you know if anything crops up from that...

 

This is on my desktop, I haven't check my laptop yet...

 

Yup! My laptop has it too...

 

For the heck of it, I check my preview build 11082 in Hyper-V(I haven't used it since Christmas), and it had a couple of entries too*Eek
