Hey Brink, thanks for this. Worked for me the first time (previous install) but can't seem to get it to run again. I tried it with entering my user name and computer name and got it to run with the username only, but it didn't create a html file on the desktop. Think you'd know why?

Hello DustSailor,

Did you move your user profile folder from the default location?

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 (output) at.

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

You're most welcome.

Eh, knowing a user name alone shouldn't cause any issues.

I just used this but I had Firefox open on this website.
Very neat little trick. Thank you.

Shawn,

I've run the Powercfg -energy report in the past on my Desktop PC without issue but I can't get it to run now. I tried to run it on my Laptop and I'm getting the same error.

Here's my background info:

Desktop PC: Custom-built Windows 7x64 Home Premium (OEM version) with an Asus MoBo. The Desktop PC is my everyday PC, used several times daily. It's been running good, no other Win issues that I can detect, no error screens/dialog's seen, boot time the same as the original OS install in 2011 .

I've run the -energy report last year without the present issue and saved it to an HTML file but that's the last time I've tried running the report since last April.


Laptop PC: Toshiba Windows 7x64 Home Premium, OEM install, standard Toshiba install extra's (recovery partitions, etc). It's mainly a backup PC to my Desktop so I don't use it often, just a daily sign-in to verify basic functions are all ok ('net access, Outlook working, etc).

The other Powercfg queries/commands work ok on both PC's (-requests, -getpowerscheme, -availablesleepstates, -lastwake, -hibernation off/on, etc).



I'm getting the following error when I try to run the -energy report on both PC's.

Could not open the NT Kernel Logger. The NT Kernel Logger is already in use. Ensure that all other performance monitoring utilities, including Reliability and Performance Monitor are not currently in use.


I googl'ed this topic and didn't find a lot of suggestions other than to disable/turn off "Power Performance Monitor" (perfmon.exe) and/or other Reliability utilities that are running. I don't see those processes running when I look at Task Manager or (Sysinternals) Process Explorer.

The searches did also suggest to disable/turn off Procmon (Sysinternals tool) but I'm not running that one on either PC.

I do run the default Windows Task Manager minimized in my Tray so I exited Task Manager to eliminate that as a possible source of the error but that didn't fix the -energy error.

Hello Scoop,

If you haven't already, restart the computer, then see if you may be able to successfully run the report.

That did it. I don't know why I can't get the "try the 'universal panacea restart' first" action loaded in my brain's RAM after all these years
