There is an inbuilt command in your computer for improving battery life as well as the performance of the system but not all users are aware of it. Some laptops directly provide an interface with option termed as “ POWER SAVING MODE ” but  if your laptop is old or don’t have this feature by default , you need not to worry because you can do the same task manually.

If you have a laptop with Windows 7 installed, you can use the ‘powercfg‘ command . It will display useful information about your laptop’s energy consumption and usage. If  you can understand and maintain  it correctly then you can extend your Battery life and performance by great amount.


Step 1: Click on the Start Menu and type “ CMD ” in the Start Search bar.

Step 2: The search will start and it will then display an icon of “ CMD ” . simply right click on it and select Run as administrator.

Step 3: It will open command line, now simply run the command “powercfg -energy” without quotes. (For windows 7 users.)

                                 -OR-

Simply run the command “powercfg /energy” without quotes. (For windows 8 users.)

Step 4: Now Press “Enter”.

Once you successfully execute this command , Windows  will run a complete scan of  your system and it will find some ways to improve performance and power efficiency.

The results of this process will be saved to an HTML file, which is commonly  present  in the “System32” folder of most of the systems.
