How to Get More Run Time for laptop

Adjust Power Management Settings

The simplest way to get the most out of your laptop battery is by adjusting the Power Management settings located in the Control Panel of your laptop. Most are familiar with these controls, and they generally have three different settings you can select from. If you plan on using your laptop for several hours in between charges, you'll probably want to select the setting that saves the most power.

Take a Look at Your Battery

Just like your car; laptops also have a gas tank; which is the battery. Unlike you car, you can increase the size of your laptop's gas tank (the battery) by replacing it with battery that has higher cell count and capacity (HP Pavilion dv4 Battery).

First look at the laptop battery from the energy point of view , since it wanted to energy conservation, it is necessary to know how to avoid cell " aging ." Typically , due to the internal resistance of the battery with the use of time and continue to grow larger, there will be a voltage drop mate , the system voltage support is not sufficient, leading to a serious shortage of electricity . Over time this will form a vicious circle , seriously affecting the laptop battery life. This is fortunate, sometimes your laptop battery failure in a very short time on the failure, it is nerve-racking . This situation is probably caused by the failure of batteries , lithium batteries this situation occurs mostly in the body, in fact, the books of the battery is like a flashlight to poke home , is one of a core consisting of electrical , just one of a failure , then it will lead to a whole series,voltage blocked, overall scrapped. So while it is charging to use electricity, do not use industrial electricity , so the voltage is too large , it will affect the discharge curve. When you start charging , do not select fast mode (BIOS setting ) , when the battery is charged with constant current charging mode , the system load current, to avoid competition for power between the CPU, hard drive , LCD phenomenon . Discharge , slow down and let the CPU , hard disk stops , the screen dimmed ( or turn off closed ) , do not run any programs until the laptop automatically shut down in order to achieve low current discharge purposes. Also, if you can find the " thermal protector " in the market , then the best. It can be achieved by adjusting the overall balance , is a very good battery backup protection equipment (HP Business Notebook 6720t Battery).

Identify Power Hogs

Another way to get the most out of your laptop battery is to identify the main consumers of energy and make adjustments so that they aren't pulling as much power as they typically would. Here are a few 'battery consumers' that can be either turned off or limited for the purpose of getting the most out of a charge:

* The Screen (adjust brightness)
* Wireless Networking Cards
* CD-ROM/DVD-ROM
* Any other ‘Extras’

Let's say that an average laptop battery is 2500 to 4000 mAh (milliAmp hours). With EVERYTHING on your laptop in use, you could be using as much as 2500 mAh each hour. At this rate, you would be lucky to get two hours out of a charge. On the flipside, wise usage of your laptop could see that rate decrease by up to 80%, allowing for much more use per charge(HP Pavilion dv7 battery).

So the next time you get set to use your laptop and want to get the most out of your charge, envision it as if it were your car and use its power accordingly. You might be surprised at how much a few minor changes can help to get more usage from each charge.
