Now notebook computers are particularly common, whether in the outdoors or in the room to be used, especially in the outdoors, the laptop is fully powered by the battery. Over time we will find the battery life has not just started so long, before battery life has decreased from 3 hours to 2 and a half hours. How is this going?

Lifetime is shorter, not the battery itself

Battery lifetime may decrease within a year due to battery misjudgment in charging and discharge processes. TThe BIOS may mistakenly shut down books due to battery exhaustion, causing a shrinking battery lifetime. To resolve this, consider battery calibration to fully utilize remaining power.

How to perform Laptop Battery Calibration

There are 3 ways to calibrate the battery: Battery calibration typically involves performing through the BIOS, manual calibration, or third-party software. Here mainly talk about the first two correction methods.

Tips: Do not recommend using third-party battery calibration software. As for the reasons, the first need to install third-party software, not the first two methods are simple; Second, in fact, behind the principle of correction is similar to third-party software and not too much unique place, but also there are potential security risks. The first two methods can be completed through battery calibration, but third-party software is not recommended.

Standard laptop battery calibration Method: Use the battery calibration function in the BIOS

Many brands of notebook computers in their BIOS which are integrated battery calibration procedures. the general English is called “Battery Calibration”, that is, “battery charge proofreading.” The battery calibration operation completed directly into the BIOS, as illustrated in the ASUS notebook and other similar books.

  1. Step 1: To boot, press (F2) to enter the BIOS menu, then use the left and right arrow keys to select the Enter Power menu.
  2. Step 2: enter the Power menu, you can see the “Start Battery Calibration” option (Figure 1), select it and press the Enter key to execute.
  3. Step 3: At this time the screen will turn blue, and there are English tips, asked to plug the notebook’s power adapter to the battery charge. When the battery is full, the screen prompts the user to disconnect the power adapter (Figure 2). After the notebook began to discharge the battery until the battery power consumption
  4. Step 4: This process takes some time, such as battery exhaustion automatically shut down. Next step, you should connect to the power adapter to charge the battery, but do not boot. After the completion of charging (charge indicator light off), you need to complete the battery calibration process.

Edit Comment: This operation is more official battery calibration method, the whole process takes about 4-5 hours, more time-consuming. If you find that your laptop battery is useless for a long time. I recommended you to implement laptop battery calibration. because a lifetime as the original, and the BIOS with this feature.

Cottage correction law: Let the notebook boot naturally discharge

Some notebook, in the BIOS, how to find cannot find the battery calibration options. Is this kind of notebook cannot carry out battery calibration? In actual fact, we can “cottage version” of the battery calibration method to operate it. Is called “cottage”, because this is not the official method of publication, but through some of our manual settings, so that books in the normal work of discharge until the automatic shutdown.
