Windows 7 Tip#3

Get a power efficiency report

Have a laptop and want to get more battery life out of it? Windows 7 includes a hidden built-in tool that will examine your laptop's energy use and make recommendations on how to improve it. To use it:

1. Run a command prompt as an administrator. To do this, type cmd in the 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:

powercfg -energy -output \Folder\Energy_Report.html

where \Folder represents the folder where you want the report to be placed.

3. For about a minute, Windows 7 will examine the behaviour of your laptop. It will then analyse it and create a report in HTML format in the folder you specified. Double-click the file, and you'll get a report -- follow its recommendations for ways to improve power performance.
