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.
