If you have a Windows 7 laptop and you want to extend its battery life, Windows 7 includes a hidden built-in tool that will analyze your laptop’s energy usage and give recommendations as to how to improve power consumption and extend your laptop’s battery life.
Here’s how to do it. 1. Run a command prompt as an administrator. To do this, type cmd in the Start Menu search box, and when the cmd icon appears, right-click it and choose “Run as administrator.”
2. At the command line, type in the following:
**You can change the output directory to anything you want – as long as the directory already exists**
3. Windows 7 will take a few moments to examine laptop’s power usage. After if finishes analyzing, it will generate a report in HTML format (Web page) in the folder you selected. Just double-click the file, and the report will open in your browser.
You can follow the recommendations in the report to improve your laptop’s power performance.
You mention:
powercfg -energy -output C:Your User Name DocumentsEnergy_Report.html
It should be:
powercfg -energy -output C:\Your User Name\DocumentsEnergy_Report.html
The “\” backslash-es” are missing !!!
Or:
powercfg -energy -output C:\Report\Energy_Report.html
The MAP “Report” has to be created beforehand !!
Greetings, Adelin
That’s what it says – the back slashes are there.
powercfg -energy -output C:\Your User Name\ Documents\Energy_Report.html
It should not be DocumentsEnergy_Report.html unless you want Documents as part of the file name.
No, actually the back slashes are not there!
I don’t see any back slashes either, TC.
Must be the Halloween goblins are out early.
The report seems to have been created, but I can’t locate it. What am I doing wrong?
I also see not back slashes, TC
Your computer is different than ours?:)
I have – on my screen – all the backslashes.
