Every laptop or Netbook user these days have the same headache of limited backup time of batteries. As far as your system is new , you will have a good backup time but when it becomes a few months old you will definitely face problem of limited battery life.

So here I am giving you a solution to Increase battery life of your laptop upto a sufficient extent.

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.

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.
