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 computer in Windows 7 and Windows 8
Note : You should run this report when your computer is idle and with no open programs or documents for the best results.
Here's How
1. Open an elevated command prompt in Windows 7 or Windows 8.
2. In the elevated command prompt, copy and paste the command below, and press Enter. (see screenshot below)
