How to check and optimize Power Efficiency in Windows 7 (aka How to get longer battery life):
  • Click on the Orb and in the search box type CMD
  • Right-click on the command prompt and select "Run As Administrator"
  • Click "Yes" to the UAC Prompt
  • In the new command prompt window type in powercfg -ENERGY
    Note the single space between powercfg and -Energy
  • It will say it is tracing the system for 60 seconds.
  • At the end of 60 seconds a file will be created: C:\Windows\system32\energy-report.html.
  • Move this file to the desktop and open in your favorite browser.
  • Do whatever it says to optimize your efficiency.
  • Enjoy longer battery life.

This is actually quite detailed as it monitors a range of features including looking for drivers that will prevent the computer from going to sleep etc.
