It is of utmost importance to the laptop users to try to increase the battery power of the laptops and this can be practically achieved by moderating the laptop usage habits. With each passing year, although the efficiency of laptop batteries increase but the effect is subdued by an even greater increment in the power needs of the laptops that don’t help to prolongate the average life of the batteries. It is now a common sense that the more the physical devices are put into use, the more will be the consumption of the battery’s power. In order to considerably increase laptop battery power, it is essential to keep in mind few important measures.

While using laptop, the unused devices must be turned off as for example the infrared transceiver, the Bluetooth radio and the Ethernet adapter. This would resultantly extend the power capacity of the battery.

Optimize Laptop Battery Use
Moreover, in order to increase laptop battery power, it is very crucial to regularly defragment the hard drive so that the frequency of spin involved with it decreases, thereby extending the power usage of the battery. Such technical measure is rational in its own way as it intends to optimize the data placement on the hard drive and helps in modulating unnecessary hard drive activity.

Yet another important measure at this context is that the start up items are required to be disabled to the fullest possible extent so that the virtual memory of the CPU is not hampered shortening the runtime of the battery.
Concluding the discussion with one last point, it is imperative to properly condition the battery that is to completely drain it and then recharge it to accomplish successful power management of the battery.
If a person follows the above mentioned tips, he or she can be rest assured that there would be a definite increase in the laptop battery power.
I’ve found one of the best ways to extend the battery life is to create a power profile that you use when on battery. I set the screen brightness to very low, set the screen to turn off to 1 min, but most importantly – find the one that controls how much of the cpu can be used. set the minimum to 0, and the max to something low like 20%.
Then when you are using the laptop, it is limited as to the amount of cpu it can use, this won’t cause problems for notes, wordprocessing, and web based stuff. But can cause some issues if you are trying to play games etc. Your results will vary depending on the laptop.
I have found it is also helpful to maximize your power saver settings. If you use Windows Vista or 7, the default setting is called balanced, which balances performance and battery life. Selecting the “power saver” plan will help you squeeze out every last bit of battery life. Re: Matt’s point, it all depends on the computer, although if you experiment and try a few of these tips http://bit.ly/KnHNf, you should see an improvement.
Very nice points. Maintaining the internal specifications right is enough to make things perfect and increase the battery life.
