TroubleShoot Power Management

Windows 7 can tell you how much power your system uses or provide detailed information about the power usage and issues caused by each application and device. This way you can optimize the way your battery is used, making It last longer. Press the Windows Key and type “POWERCFG –ENERGY –OUTPUT ”, and it will create a file called energy-report.html in the folder specified by you, after observing your PC for 60 seconds.
