Keep it Cool
The harder your fan works the faster your battery will deplete. Be sure to keep the vents on your notebook clear of dust and dirt. Modern computers generate a lot of heat and use a lot of battery capacity to keep them cool. Try not to set up notebook on a mattress or couch cushion which limits airflow. If the fan is running fast all the time be sure to consult your IT support specialist to locate software that can be causing the computer to overwork.
Lower the Screen Brightness
Lowering the screen brightness can greatly increase the charged life of your battery. Most notebook computers have shortcut keys to change the screen brightness. If it does not have shortcut keys then go the Start Menu and type power. Choose the Power Options and locate the screen brightness slider along the bottom of the window.
Hibernate and Sleep
While you are in the power settings menu you can also adjust the power settings. Most notebook computers include an optimize battery life plan. Choosing that plan adjusts many settings which can extend your battery life. If you want to dig into the details you can click “Change Plan Settings” and adjust the time to dim the display, sleep time, and hibernate time to increase battery life.
Unplug when Charged
Most notebook batteries will give you 300 to 500 full discharge cycles in their life. Be sure to exercise the battery occasionally. A notebook computer kept fully charged all the time will tend to have a short battery life.
