Laptop battery detection and recovery

To the Laptop Battery that use for within 1 year, its battery life get shotter, not because of the battery normal aging, but because during the process of battery in the number of charge and discharge, the notebook BIOS system have a miscarriage of justice to the battery power.

There is a certain power in the battery, but the BIOS think that the power is exhausted with mistake, so that Laptop was forced shutdown, if happened this situation, first do not think is the problem of battery quality, we can use the “battery correction” this such a simple way to let the remaining power into full play.

How to "battery calibration"

Battery correction have more than one way, there are usually three ways: using the battery calibration programe in BIOS, artificial way and the use of third-party battery calibration software, today we mainly talk about the first way.

Standard calibration method: using notebook BIOS battery calibration

Many brands of notebook computers are integrated battery calibration programe in its BIOS. That is “Battery Calibration”, Directly into the notebook's BIOS will be able to complete a battery calibration operation, for example the Asus Laptop, other brands of laptop are similar.

step 3: Then the screen turns blue, and prompted to plug the notebook power adapter to charge the battery. After the battery is fully charged, the screen prompts the user to disconnect the power adapter. Then the laptop began continued to discharge the battery until the battery is exhausted.

step 4: This process will take some time, after the battery is exhausted automatically shut down, then plug in the power adapter to charge the battery, but do not boot. After Charging is complete (charging indicator goes off), and the battery calibration process is completed.

This operation is the official battery calibration approach, the whole process takes about 4-5 hours, and time-consuming. If you find your laptop battery did not take a long time, such as a few months, and the battery life is not as good as the original, and your notebook BIOS have this feature, proposed try it.
