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

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

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

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.
