You can consider that you don’t need to know about power management in Windows 7, but the next time you’ll use a laptop, notebook or another device that uses Microsoft Windows 7 you will find this very useful. It is said that Windows 7 is designed to help your battery last longer by running fewer background activities and the processor does not work as hard as previous versions of Windows and it draws less power.
Windows 7 power plan
The basic power plan managements screen shows you which plan (Balanced, Power saver, High performance) you are running. It also shows a warning if you are not currently using the most efficient setting. This popup appears when you click on the Windows battery icon, along with the information presented when the mouse is hovered over the battery icon. Using this screen you can Select a power plan between these 2 options: balanced tries to find the best way to combine performace and power, the Power saver gives you the most battery life. As you can easily understand, High performance is running your computer with about no power saver at all: Windows 7 will turn of your monitor after 15 minutes of no moving the mouse or hitting any keys, but your computer will never go into sleep mode or standby.
Remember it’s not an automatic select, you have to do it yourself every time you plug in and unplug your laptop if you want maximum efficiency.
