Laptop battery calibration techniques05.26.14

Shorter battery life, not the battery itself.

For the battery using time within 1 year, shorter battery life, often not because of battery normal aging, but because the battery in the process of many times of charging and discharging, notebook BIOS system has a miscalculation on battery power. Original battery has a certain power, but mistakenly think that the BIOS battery has run out, let your laptop to force to turn it off. If appear this kind of battery life shrink, the first battery quality problem is not busy to conclusions, and can be done by “cell calibration” this simple and easy way to let the rest of the power out into full play.

How to make “battery calibration”

Battery calibration method is more than one, there are generally three kinds of ways: using BIOS battery calibration program, manual Battery Calibration and use third party Battery Calibration software. Here mainly to talk about the first two correction methods.

Tips: do not recommend the use of third party Battery Calibration software. As for the reason, first of all need to install third party software, not the former two methods is simple; secondly, the correction principle behind is similar, there wasn’t too much unique local third party software, but also a potential security risk. So in the front two methods can complete battery calibration case, does not recommend the use of third party software.

The standard correction: correction function used the books of BIOS battery

Many brands of laptops in the BIOS, integrated with battery Calibration procedures, general English is called “‘ Calibration”, namely “Battery check”. Directly into the laptop BIOS battery calibration operation, will be finished here in asus notebook, for example, simple talk about how to operate, the operation of the other laptop similar way.

Step 1: boot, boot screen after press “F2″ to enter the BIOS menu; Through the or so direction key, the Power menu choice.

Step 2: enter the Power menu, you can see “Start ‘Calibration” option, select it and press the return key.

Step 3: then the screen will become blue, have English tips, and requested the notebook power adapter plug in to recharge the battery. After the battery is full, such as screen and prompt the user to disconnect the ac adapter. Notebook to continue after discharge the battery until the battery runs out.

Step 4: the process over a period of time, such as automatic shutdown after its battery runs out, then plug in the ac adapter to recharge the battery, but don’t start up. (charge indicator extinguished) after fully charged, such as cell calibration process is completed.

This operation is the official battery correction method, the entire process takes about 4 to 5 hours and more time-consuming. If you find that your laptop battery doesn’t work long time, such as a few months, battery life is better than at the beginning, and laptop BIOS with this function, suggested to implement it.

Introduce the necessary procedures manual Battery Calibration

Step 1: in the operating system (Windows XP), into the “power options”. “Choose to use the scheme of” power to “open”, and to “close the monitor”, “off the hard disk” is the most short time, while the system standby should be set to “never”.

Step 2: in the “Power Options” “alert”, cancel all alert options, the purpose is to let the battery is fully drained until the shutdown.

Step 3: set of finished, close the application, all closed WIFI, unplug the power adapter, battery powered. Don’t do any operation, until the battery is depleted shutdown. The estimation process is relatively long, may take several hours. After discharge, even the power adapter, the battery is full, then completed a battery calibration.

After correction, whether to try the battery life time increased, if not clear, can be in accordance with the above method again, but is not recommended for regular. If the battery has a long time of use, and the battery after correction, the effect is not obvious, it may be the battery life of its own natural aging. In addition, if the laptop battery is normal, we do not recommend battery calibration operation.
