Now here is the instructions:

The easiest way to get the best battery life out of your Dell laptop is to select one of the pre configured power plans. The pre configured power plans automatically adjust key settings that can have a significant impact on battery life, such as reducing screen brightness or dimming the display when you are not actively using your laptop.

To extend battery life as long as possible during a working session

Turn off wireless - Your wireless card is a significant drain on your battery. If you don't need to be connected to a wireless network, then you should turn off wireless. Press the F2 key or use the wireless switch to turn wireless on and off.
Avoid multitasking - If you limit the number of applications you have running or the number of windows or tabs you have open, your battery will last longer.
Limit power-intensive activities - Batteries will last a lot longer if you are reading emails and editing documents than if you are watching a movie or playing a video game.
Change the Power Plan
On the notification area of the taskbar, right-click the Battery icon.
On the options list, click Power Options.
Select a power plan on the battery meter, such as Power Saver or Balanced.
