How to Get More Running Time from Each Charge

Have you ever wondered why it is that the pa3399u battery life on your laptop seems to vary each time you use it? If it's the same battery being used, what causes it to either last longer or die quicker from time to time?

To get a better understanding of why this happens, think of your laptop pa3465u battery as if it were a car. Just like a car, laptop batteries have a 'gas tank' that stores the energy it needs to function. This is what is often referred to as the 'reservoir' or capacity of charge per cycle of the battery. And as is the case with a car's gas tank, the amount of usage provided by a battery with a full reservoir is greatly affected by how the machine is operated.



The simplest way to get the most out of your laptop pa3383u 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.

Another way to get the most out of your laptop pa2487u 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 pa3107u 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.

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.
