Your Asus laptop is your workhorse and has served you faithfully, but lately have you noticed that it drains much faster? And at the same time, the charge indicator shows that the battery is still ready to work. Do not rush to panic and urgently look. Try calibrating the battery first. How to do it right, you will learn from the article.

Why do you need an Asus battery calibration?

Before getting down to business, you need to tell what calibration is. This is the process by which the correct parameters of the battery and laptop controllers are set. As a result, the charge indicator displays reliable information, and the battery serves as it should. The laptop stops turning off when it wants to. Calibration allows the battery to charge the battery to 100% percent and, accordingly, to discharge longer.

Time battery life laptop after this procedure increases markedly.

Most often, laptop batteries require calibration:, and (from)

Asus battery calibration step by step guide

Briefly, the Asus battery calibration process consists of three steps:

Charging the battery up to 100%.
Full discharge to zero.
Recharge to 100 percent.

Each stage has its own nuances that you need to know in order for the result to meet your expectations. Let's talk about everything in order.

Fully charged battery.

it is necessary to prepare the computer for calibration: disable the transition to sleep mode (hibernation). Do the following one by one: From the Start menu, select Control Panel, then Hardware and Sound. In the "Power Options" tab, check the icon next to "Never". Great, now the device will not “go to sleep” ahead of time;
connect the laptop to the network and wait until it is fully charged. At the same time, work on the device as usual, or leave it alone - this will reduce the charging time.

Discharging the battery.

when the indicator showed that the Asus battery is 100% charged, unplug the laptop from the power supply;
now wait until the device is discharged to 0. You can “help” the battery by using the laptop to the fullest: watch videos, listen to music, play your favorite games, run other energy-intensive programs;
keep an eye on the charging indicator - the lithium-ion battery must not be completely discharged. Full discharge is easy to check: the screen is off and the laptop does not start even when you press the power button.

Charging the battery up to 100%.

as soon as the laptop is completely discharged, immediately connect it to the mains. Leave the computer alone or work in the usual mode - it's up to you, there is no consensus among experts.
After fully charged, unplug the device from the power supply. Calibration is completed, now the Asus laptop battery should work correctly, the indicator will reflect reliable information.

In addition to manual calibration, there are special utilities who will carry out the entire process on their own. You can start this operation through the BIOS, or by downloading a special utility.

A few words about the correct attitude to the Asus battery

You can extend the life of your Asus Li-Ion battery by knowing and following a few simple rules:

Keep an eye on the temperature: it is impossible for the laptop to be turned on in the cold -100 or in the heat from 350C. Severe cold has a detrimental effect on a charged battery, it can instantly discharge or even fail. High temperatures increase the risk of damage and even explosion of the battery during operation.
Do not allow the battery to remain completely discharged for a long time. An “empty” battery takes 10-14 days to deteriorate permanently.
If you constantly work from the network, it is better to disconnect the battery so that it does not wear out.
Calibrate your laptop every 2-3 months to keep the battery working properly.

In the case of an incorrect display of the battery charge, calibrating the laptop battery will help you. Over time, the original battery capacity of your device is lost and full charge may not be displayed correctly (5% charge is displayed, although the real charge is 20-30%). Note that physical wear and tear cannot be repaired, but controller reading errors and software errors will be corrected.

How often should the battery be calibrated?

Some manufacturers recommend calibrating every two to three months. This helps to more accurately read the battery readings.
In fact, you should not worry about such frequent manipulations if you do not care about the most accurate charge indicator. But when your laptop turns off without any warning, or you notice a rapid battery drain in the last 10-15%, then it's time to calibrate the battery.

How to manually calibrate a laptop battery

On the this moment 2 main calibration methods are used: Manual or Software. Both methods work on the same principle - full discharge and full charge of the battery to restore the performance of the charge controller. The only difference is that laptop battery calibration programs can display more information and perform additional software manipulations to obtain best result. But on personal experience we can say that the differences between these two methods are minimal.

So let's get started. The whole point of calibration is to fully charge and fully discharge the battery. In this case, the indicators of the charge controller will be reset, which will allow you to more accurately determine the charge readings in the future.

First, open the settings for your power plan: Control Panel - Power Options

Setting the power plan

Change Extra options

Expand battery settings and select options as shown in the image.

the main objective these manipulations, so that at the end of the charge the device does not go to sleep, but goes into hibernation, which in our case is more convenient. Set the level full discharge 5% or less, the less the better. Then set the prohibition to go to sleep or turn off the display when running on battery so that the battery discharge process is not interrupted. After performing all the manipulations, you need to set these parameters by default or according to your preference.

Procedure:

Charge your battery up to 100%
Disconnect the power cord and completely discharge the battery before shutting down (or going into hibernation)
Connect the device to the mains and charge it up to 100%

Laptop Calibration Programs

Software calibration is a rather complicated process. A large number of battery and laptop models, differences in chipset drivers, ACPI drivers and many more reasons do not allow creating a universal calibration application. But such applications still exist. Most of them are created by device manufacturers, which is not surprising, since software component support is one of the manufacturer's responsibilities.

BatteryCare

To check the charge and collect battery statistics, it will be great free app– BatteryCare. It does not have the ability to calibrate, but the information that is displayed through this software can tell you if there are any shortcomings in the laptop and its power supply.
BatteryCare can be downloaded from the official website of the developer. This utility shows the battery charge and the approximate time until the battery is discharged in the tray. The app can monitor CPU temperature and hard drive and notify you if they are overheated.

Another program for calibrating a laptop battery is Smarter Battery (download). This utility is paid, but there is a free promo period of use. The functionality of this application is richer, unlike the previous utility. Collection of statistics, notifications, widgets, capacity, power settings - the main list of application functions. Registration is required in order to calibrate.

If this software is not suitable for you, try to pay attention to the programs and tips from laptop manufacturers.
Almost every manufacturer has a laptop battery calibration utility, usually included in the pre-installed software package.

In addition, it is possible to perform calibration via laptop BIOS. The Samsung website has this topic, which may also apply to other laptops (c Phoenix BIOS)
For other manufacturers (Asus, Acer, Dell and others), either the utilities are missing or are very outdated and are available on limited quantity models.

To maintain the correct operation of your device and its power, you should know a few rules:

Always keep your drivers up to date: ACPI drivers and chipset drivers are the main components responsible for power supply schemes and the interaction of the main software and hardware components of your device.
BIOS/UEFI update. Maintenance current versions firmware has a positive effect on the power supply of the laptop.
Use of different power supply schemes depending on loads. Surfing the Internet and watching movies does not require High Performance Mode, and sometimes this negatively affects the battery performance.
In cases where the laptop runs only on mains power or the battery is completely discharged in 10-15 minutes, you should consider purchasing a new power source or contacting Service center for hardware diagnostics, if new battery didn't help.

We hope that this article has helped you in resolving your issue. If you have any additional questions or difficulties, write comments to this article, we will try to help.

Have a great day!

Most laptops have a built-in battery that allows you to work on the device for some time without being connected to the network. Often such equipment is configured incorrectly, which leads to inefficient use of charge. You can also optimize all settings and set up a suitable power plan manually using the built-in tools operating system. However, it is much more convenient and correct to perform this process through specialized software. We will consider several representatives of such programs in this article.

The main purpose of Battery Eater is to test battery performance. It has a built-in unique test algorithm that will determine the approximate discharge rate, stability and condition of the battery in a short time. Such diagnostics are carried out automatically, and the user can only observe the process itself, and after that, get acquainted with the results obtained and, based on them, adjust the power supply.

From additional features and tools, I would like to note the presence of a general summary of the components installed in the laptop. In addition, there is also a test that allows you to determine the condition of the equipment, the speed of work and the load on it. You can also find more detailed information about the battery in the system information window. Battery Eater - free program and is available for download on the official website of the developer.

BatteryCare

Immediately after launching BatteryCare, the main window opens in front of the user, which displays basic data on the state of the laptop's battery. There is a scale of operating time and the exact percentage of battery charge. The temperature of the CPU and HDD is shown below. Additional Information about installed battery is in a separate tab. The declared capacity, voltage and power are displayed here.

The settings menu contains a power control panel, which helps each user to set the necessary parameters that would be suitable for the battery installed in the device and maximize its operation without connecting to the network. In addition, BatteryCare has a well-implemented notification system, which allows you to always be aware of various events and battery level.

Battery Optimizer

The last representative on our list is Battery Optimizer. This program automatically diagnoses the battery status, and then displays detailed information about it and allows you to set up a power plan. The user is prompted to manually disable certain hardware and features in order to prolong the operation of the laptop without connecting to the network.

Battery Optimizer allows you to save multiple profiles, making it possible to instantly switch power plans to work in different conditions. In the software in question, all the actions performed are saved in a separate window. Not only their monitoring is available here, but also rollback. The notification system will allow you to receive messages about low battery or remaining time without connecting to the network. Battery Optimizer is freely available on the official website of the developer.

Above, we looked at several programs for calibrating a laptop battery. All of them work according to unique algorithms, provide a different set of tools and additional features. Choosing the right software is quite simple, you just need to build on its functionality and pay attention to the availability of tools of interest.

Laptop battery calibration corrects errors in the operation of the controllers and allows you to keep the battery charged longer. Almost every model of a modern laptop is equipped with lithium-ion batteries of different capacities, depending on the specific equipment. This approach makes it possible to ensure long-term operation of the device in one charge cycle, which is why portable equipment is valuable. One way or another, any battery gradually loses its capacity over time and discharges faster, especially with heavy loads on CPU, video card and HDD. However, if you operate the laptop correctly, then the threshold for reducing the efficiency of offline operation will occur very slowly.

Calibrating a laptop battery is the most important step in initial setup new device, which is also relevant for other equipment running on Li-ion batteries such as smartphones and tablets. This procedure is recommended for both immediately after purchasing a laptop, and in the process of using it. Calibration involves the intentional conduct of charge-discharge cycles, and is done so that the controller chip can display the real percentage without glitches. In addition, this procedure sometimes helps to "extend the life" of the battery when, for example, there is a sharp drop in charge or battery life lasts no more than 20-30 minutes in normal load mode.

There are several ways to do this operation today, and one of them is manual calibration using standard Windows tools. The method works on any version of the OS and is practically the same, all you need is attentiveness and strict adherence to the instructions. First you need to check the current battery capacity and its level at a hundred percent charge. Surface information can be obtained as follows:

Paste Charger and wait for the charging to finish;
Disconnect the laptop from the network;
Check the battery level in the power settings.

In the event that immediately after disconnection charging block out of the socket percentage is less than 100, then you need to calibrate the battery.

The Windows OS toolkit also suggests the possibility of obtaining more detailed information. The command line will help you find it out, which opens by typing the “CMD” command in the search, you need to run it as an administrator by clicking right click mouse and selecting this option. Then type in the value powercfg.exe -energy -output d:\report.html, where D is the name local disk, which in your case may be different (C, E, and so on). This is where the report file with the name report and the .HTML extension will be saved. Open it with any browser and scroll to the "Battery Information" tab, then compare the last full charge and estimated capacity. If the first is much less than the second, then without fail calibrate the battery.

Operating windows tools give only information about the state of the battery, and you need to carry out the calibration procedure in manual mode or using dedicated software. First, it is better to try to do everything yourself and if there is no result, resort to software. Manual calibration is carried out in several steps:

Full battery charge;
Turn off the power supply and discharge to 0;
Network connection.

Here it is very important to correctly set the power supply mode, because by default the system selects “Balanced”. In the above procedure, it is recommended to set "High performance" in the settings, as this turns off various energy-saving technologies and increases the likelihood of a successful calibration. In addition, when the battery level is low, the laptop will go into sleep or hibernation mode and will not allow the battery to “land” to zero.

A laptop battery calibration program can play a very important role and help you to cope with this task in the most effective way. In addition, when using the software, the whole process is carried out in automatic mode and the user does not need to change any configuration. However, it must be borne in mind that various programs are used for each laptop model.

Battery calibration Asus laptop in most cases, it is carried out in the BIOS, since this manufacturer often integrates the necessary application in the form of a technological tool motherboard. Most often, this feature is present in the Phoenix BIOS, but you can check it yourself:

Disconnect the power adapter from the laptop;
Reboot or turn on the device, and then press F2 (sometimes another F-ka);
Go to the BOOT tab and find the Smart Battery Calibration menu, start the process.

Note: It is recommended to search for this item in all BIOS sections, and its name may also differ, but it always contains the word Battery. If there is no item, then it is better to calibrate manually according to the scheme described in the previous section of the article.

For laptops from manufacturers such as Samsung and Acer, there is an excellent calibration program on the Internet called. Its peculiarity lies in the possibility of faster discharge-charge cycles, due to the fact that it automatically starts the process of searching for the Pi Number, while giving the maximum load on the central processor. In general, its main purpose is to test and diagnose the state of the battery both in idle mode and in peak loads. With it, you can perform several cycles in one hour by selecting fast track and high performance in laptop settings.

The well-known manufacturer Lenovo has released a profile utility called . It is quite multifunctional regarding battery calibration, provides the user with comprehensive information and tools for correctly configuring the battery. Before starting the procedure, connect the power supply, close running applications and background processes, and do not use the gadget during the action.

- very useful official software for Hewlett-Packard laptops. A large arsenal of tools makes it possible not only to calibrate the battery, but also provides a variety of functionality for diagnosing the general condition of the device. In the "My Computer" section, you will find a battery check item and after the test, the program will notify you of the most preferred actions.

Each experienced user portable gadgets already knows and adheres to generally accepted advice on how to avoid or, at least, delay the battery life as much as possible. First of all, don't use it. This is by no means a joke, because when you are working on the device and there is an outlet nearby, you need to pull out the battery and plug the power adapter into the connector, so when you really need battery life, you will have much more time. This is due to the fact that any battery has a given number of cycles and energy intensity, which in any case is lost during natural operation.

Further, if you do not use the battery, then it is best to leave it at 60-70 percent. Surely you have never paid attention, but a new gadget, be it a smartphone or a laptop, always shows exactly this level of charge the first time you turn it on. Lithium-ion batteries do not like to be overcharged and completely depleted. And lastly, always try to comply with the recommended operating conditions, that is, do not allow the gadget to overheat, do not use the laptop in rooms with a high level of humidity or at low temperatures. In general, in the instructions, all these tips are presented in an understandable and accessible language.

Programs and utilities for calibration battery laptop

To improve the efficiency of the laptop battery, it is advisable to periodically calibrate it. This can be done manually using special programs, as well as through the utilities in the BIOS. As you know, a laptop battery consists of a controller (microcircuit) and individual cans connected in parallel and / or in series. The controller monitors the process of charging and discharging the battery cells. The problem here is that during the operation of the battery, the controller data begins to diverge from the real state of the cans. As a result, the laptop can “go offline” even with a charged battery. Under such conditions, the battery cannot be used and must be calibrated. Calibration of the laptop battery ensures that the charge of the battery cells and the readings of the charge controller are brought to the same level. In this material, we will try to figure out how this is done, and what programs and utilities are used.

Calibration is required in cases where the data on the charge of the battery cells of the battery controller does not match their actual state. Let's take a simple example. The degree of charge of the battery cans is 90%, and the controller has information about their charge by 70%. As a result, when the controller sees 10%, it will send the laptop to sleep. But in fact, the battery has a charge of 30% and could still work. As a result, battery life is reduced and the user has to charge the laptop more often.

With the help of programs for battery calibration and manual method you can get rid of this error. Calibration also eliminates the "memory" effect. Not to be confused with the memory effect.

This is a situation where the battery "remembers" the degree of charge when connected to the mains, and then gives its charge up to this mark. As a result, the battery capacity of the laptop is not fully utilized.

Correct this situation and help programs for calibrating the battery. All modern laptop models use lithium batteries and they don’t have the “memory effect” that is found in batteries.

How to evaluate the capacity and condition of a laptop battery using the program

Before carrying out the activities that are described later in this material, make an assessment of the laptop battery capacity. As they say, you need to realize and comprehend the condition of the battery. To do this, you need to perform the following sequence of steps on a laptop running Windows.

Run a command prompt with administrator rights. For those who have forgotten how to do this, type cmd.exe in the Start menu and use context menu run a command prompt on the laptop as an administrator of the computer.

AT command line type the following:

powercfg.exe -energy -output c:\report.html

At the end of the line is the path where the report file and its name will be saved.

Wait for the system analysis to complete and then go to the path you specified to view the report file. In our case, this is the report.html file in the root of drive c.

In the resulting report, we are interested in the section called "Information about the battery." There you need to pay attention to the estimated capacity and value at the last full charge of the battery. In the same section, the battery type of your laptop will be indicated.

As you can see, the last full charge shows a capacity much less than the nominal one. Even a message is displayed stating that the last charge was less than 50% of the battery capacity. In this case, you need to use programs and utilities to calibrate, or rather, recalibrate the laptop battery.

But it should be remembered that calibration is not a pill for all diseases. If the battery has lost capacity due to a long service life, then no amount of calibration will help it. Recalibration programs are designed to eliminate the error in determining the battery capacity.

What are the programs for calibrating a laptop battery?

In automatic mode, you can perform calibration using special programs. These utilities are released by laptop manufacturers.

HP laptops

In particular, HP offers a UEFI System Diagnostic tool for this. To use this utility, you need to press Esc when booting the laptop and after the F2 boot menu appears. You will enter the system diagnostics, where you will need to select "Battery Test".

On the page that appears, you will need to click "Start battery test". A check will be launched, which will take a certain time. After its completion, the program will offer certain actions that are recommended to be done.

You can also calibrate the battery using the HP Support Assistant in Windows. To do this, do the following:

Go to Start -> Programs -> HP Support Assistant. As a result, the program will start and a welcome window will appear. In this window, you can specify the parameters of the utility and prevent the window from being displayed during further launches of HP Support Assistant.

In the window that appears, open the Diagnostics tab and click the HP Battery Check button. The program will run for a while, and upon completion, it will display the results of the battery test. You can see everything in the photo below.

Together with the result of the analysis of the battery condition, the program will issue the necessary recommendations, which may include replacement, calibration, successful completion of the test, etc.

Lenovo

In case of Lenovo laptops The Energy Management software should be used to calibrate the battery. Most Lenovo Idea laptop models are equipped with an Energy Management utility designed to manage power. The program is possible.

After installation, launch the program and click the gear in the main window. In the next window, click "Start" in the "Reset indicator" line. In the window that appears, the calibration will need to be confirmed by clicking the "Continue" button. All actions are shown in the screenshots below.
