A program for automatically calibrating the battery of an asus laptop. Manual and automatic laptop battery calibration

Each of us has faced the problem of reducing the life of portable devices. If previously your mobile phone or laptop worked for 2-3 days, now you need to charge it every day, have you noticed? It's all about the battery, or rather, its volume. In this article we will look at the principles of calibration of modern lithium-ion batteries, it is a simple process, you can do it.

During operation, the battery capacity decreases, this is due to the gradual breakdown of the battery controller. A faulty controller may indicate that the battery is charged when it is only 70% full, thus significantly reducing the operating time of your device.

As mentioned above, modern lithium-ion batteries consist of a controller and battery cells. The controller monitors the voltage in each of the cells, so the maximum voltage is equal to 100% battery charge or 4.2 volts of voltage in the battery cells.

In order to return the device to its former operating life, the battery is calibrated; this is a simple process and following the simple instructions below, anyone can do it.

Battery calibration consists of three points:

1. Charge the battery to 100%.
2. Discharge the battery to 0.
3. Charge the battery to 100%.

Just 3 short points, now let's figure out how to do it right. After you charge the battery to the maximum, it will need to be discharged to complete zero, and the charge level of the battery cells on the controller will equalize, at which point they will all be equal to 0%. After this, the battery can be called calibrated; to consolidate success, you need to charge the battery again to 100%.

Now about the pitfalls of the process, in order to discharge the device you need to disconnect it from the power supply, but as soon as you do this, the laptop will change the power consumption mode to a more economical one and, without your long attention, turn off the display, and then go into sleep mode.

Thus, you will need more than one day to completely discharge the battery. But we are practical people and value our time, so we need to discharge the battery quickly, and, therefore, prevent the device from falling asleep. To prevent the laptop from automatically turning off when the power is turned off, you need to change the power plan, you can do this like this:

Go to Start > Control Panel > Hardware and Sound > Power Options

In the menu on the left, select the item Create a power plan. Set the switch to high performance, this will allow the computer to use all its power and drain the battery faster, enter the name of the power plan. Battery calibration- would be a reasonable name.

In power plan settings we prohibit turning off the display or switching to sleep mode by selecting the appropriate values in the windows that open.

A plan for quick battery calibration has been created, select it and wait for the result.

If you do not feel a strong desire to create new power plans or for some reason this is not possible, use another method, go to BIOS.

In order to enter the BIOS, you must press the key when you turn on the laptop, but before the operating system starts loading Del, this is the most common key, but there may be options, such as: F2, F10, Esc.

A smart option would be to quickly press these 4 keys immediately after turning on the device. While in BIOS, the laptop will not be able to turn off the screen or go into sleep mode; it will work until the end.

The disadvantages of this method are the absence of a battery indicator in the BIOS and the inability to predict when the laptop will turn off. In addition, a discharged battery must be immediately connected to the network to begin the charging process, in order to avoid negative consequences, it is better not to hesitate.

In addition to manual calibration methods, laptop owners Lenovo And HP can use official utilities from the manufacturer; I will leave links to their downloads at the end of the article.

I would also like to add a few tips regarding the operation of lithium-ion batteries:

1. Batteries do not do well at temperatures from minus 10 to plus 35. At low temperatures it is significantly accelerates the battery is discharged, it may fail, at high temperatures in Celsius there is a risk of explosion, be careful when operating the batteries and observe temperature conditions.

2. Lithium ion batteries should not be completely discharged, this will harm them.

3. Manufacturers do not recommend keeping the laptop constantly connected to the power grid; this accelerates battery wear. Lenovo laptops have a special mode that uses only 50% of the battery capacity when powered from the mains, thus extending its life.

That's all, have reliable batteries.

At one time, laptops gained immense popularity due to the ability to run on a battery, which made it possible not to be confined to one place and to do the necessary work almost everywhere. The first models could last only a short time without a charge, and the nickel-metal hydride batteries used had a lot of disadvantages. But manufacturers did not sit idly by, and over several decades, battery manufacturing technologies have undergone dramatic changes. Today, the vast majority of laptops use lithium-ion batteries. They can last quite a long time and lack many of the disadvantages of their predecessors.

However, they are not perfect and may also become unusable over time. A battery malfunction means that it discharges very quickly, or the laptop does not display the charge level correctly. In this case, manufacturers and equipment sellers recommend purchasing a new battery. But, since the cost of the original component is quite high, you can try to correct its operation yourself. Depending on the degree of damage, it is necessary to either replace the battery cells, or it will be enough to reset the laptop battery controller.

It is the latter possibility that we want to talk about in more detail in today’s material. You can find out in what cases you need to reset the controller, and we will also tell you about possible ways to do this yourself at home.

First, it's worth finding out what a battery controller is. This is a small microcircuit built into the battery itself that controls its operating condition, as well as the charging and discharging process. It interacts with the power controller on the motherboard of the laptop itself, and also transmits the necessary system information to the operating system. We hope the diagram is clear to you. We tried to describe everything in simple words, but if you want to know the technical details, search the Internet.

When this small chip stops working correctly, you may need to reset the controller. This procedure is also popularly known as battery calibration. By and large, there are only two situations when this may be required: incorrect charge display and replacement of battery cells.

An incorrect charge display means a situation where the laptop’s operating system, even after a long charge, shows that the charge level is less than 100%, or the charge drops sharply, and the laptop turns off not after a few hours, as it should, but much faster. Many people begin to think that the battery has become unusable, but this is not always the case. The problem very often lies in its controller, which simply does not display the charge correctly.

By replacing battery elements, we mean that some workshops and service centers may offer so-called battery repacking, that is, replacing internal units that have become unusable. After this, the controller must be reset so that all new elements are recognized and can be used correctly. Although, if after replacing the blocks something does not work correctly, you have every right to make a claim and demand that the defects be corrected.

Now let's look at how to reset a laptop's battery controller. Let's touch on the software and manual methods.

Controller soft reset

On some sites you may see a recommendation to use the Battery EEPROM Works program. This is truly a very powerful and advanced utility that can, in some cases, literally revive the battery. But there is one big BUT! To use it, you need to know a lot and be able to understand electrical circuits, as well as have the necessary adapters, which are not always easy to get on the open market. We will not recommend this program for use in home devices, as it is very easy to permanently damage the battery. What then is right for you?

Battery EEPROM Works window

Almost every manufacturer has built-in power management utilities. It can be downloaded from the support site, on the driver download page for your device, and in some cases the utility can be either pre-installed or recorded on the included driver disk. Select the reset or calibration option and follow the on-screen instructions exactly. Most often, the utility discharges the battery to zero, after which it charges up to 100%. The controller will remember the extreme charge level indicators and will work as it did immediately upon purchase.

Manual controller reset

If for some reason you cannot find or install the power management utility, you can reset or calibrate the battery manually. How?

Disconnect the laptop from the electrical outlet, and then switch it to BIOS mode. You can read more in the article how to start BIOS mode.
Leave the laptop and do not touch it until it is completely discharged. Take care that it does not overheat.
Without turning on the laptop, put it on charge. Wait until it is fully charged; to do this, you can leave it overnight.

In 99% of cases, such simple steps will help bring the battery back to life. Well, if this doesn’t help, buy a new battery, or connect the laptop directly to the outlet, removing the battery.

If you only use your laptop at home, then to reduce wear on its battery, it would be better to remove it. But before that, charge it to about 80% and also check the charge level from time to time as it is prone to self-discharge. After removing, connect the laptop to the power supply and use it like a desktop computer. This option is suitable for those who have a laptop in only one place, since with this use you can lose data if you disconnect the laptop from the power source while working.
To increase the operating time of your device, set the appropriate parameters in the power plan settings. If necessary, use the power saving mode.

Conclusion

Friends, today we talked about how to reset a laptop charge controller. We learned that sometimes the problem lies not only in the computer hardware, but also in the software. Therefore, there is no need to rush to order a new battery right away. We hope everything worked out for you and there are no questions left. Don't forget to share your opinion in the comments.

If you are a fan of ASUS laptops, then you have probably heard the legend about the origin of this brand. The name of the brand was given by the ancient mythical winged creature Pegasus, sharing the last four letters with the inventors. Apparently, the creative team initially decided to convey to users the idea of the truly unique performance of this device through a mythical image.

The flight of thought was adjusted by marketers who were looking for a way to highlight their brand, make it recognizable and something that would catch the eye in the first place. Of course, the letter A in any alphabet is guaranteed to be higher than the letter P, so the proposal to eliminate the first three letters was accepted.

What is calibration?

What is calibration and how does it help you? Calibration is the process of zeroing the readings of a battery voltmeter. Resetting allows you to return the controller back to normal if the battery is, in principle, still alive. The point is this. A charge indicator of 100% means that the voltage in the battery cells has reached its maximum value. This is 4.2 V. It is at this moment that the controller - the electronic brain of the battery - signals that the battery is fully charged. However, if the readings are not taken entirely correctly, the signal will arrive much earlier than the battery is charged.

The controller, like any brain, sometimes needs to be rebooted and rethought its usual algorithm of actions. Simply because after many months of work, this brain begins to lose count and incorrectly count volts and percentages. If you fully charge it, then completely discharge it, and then recharge it to capacity, this may well help the controller restore its functions and no longer let you down with false information about the battery being fully charged. Again, we repeat again, if the battery itself is normal. Myths and legends that calibration will help revive a dead battery are not relevant here.

How to restore the battery?

Calibration didn't help and your laptop battery still doesn't hold up? This means that you will have to disassemble and restore! Consultants of specialized companies - in particular, uabattery.com - warn that repairing laptop batteries should be trusted to professionals. In general, it’s better to buy a new one right away. In any case, it will last longer than the restored one.

Do you intend to deal with unruly equipment yourself? Well, then get your scalpel, soldering iron, multimeter and car light bulbs ready. Divide the battery into two parts along the seam, measure the voltage on each element inside the case, and discard those where the voltage is less than 3.7 volts. In their place, install new “barrel” elements (battery elements are exactly what the battery elements look like in appearance). The marking of new elements should be similar to the old ones. After this, seal the body.

Is the laptop working, the battery is charging and has started to hold a charge longer than before? Congratulations! No? Then the offer from the online store uabattery.com is still valid. Contact us and our consultants will help you choose a new battery compatible with your laptop!

Modern laptops are equipped with Li ion batteries of different capacities. Thanks to this, for each specific device the required battery volume is calculated to maintain long-term battery life. Autonomous operation is one of the reasons why users prefer laptops.

During the operation of the device, the battery loses its original capacity, charge/discharge cycles decrease, this is especially noticeable in demanding programs and games. If you follow all the requirements for proper operation of the device, then such a problem may not arise. To preserve the capacity and restore the functionality of the laptop battery, calibration will come to the rescue.

When is it necessary to calibrate a laptop battery?

Battery calibration is primarily necessary when problems are observed fast battery consumption in undemanding applications: browser, text editors, etc. In such situations, the charge may drop to 0 in a few minutes. It will also be useful when the system shows incorrect charge percentage or its level remains within one value, i.e. When connecting a charger, the percentage does not increase.

We also recommend that you perform calibration immediately after purchasing your laptop. This is necessary for the initial setup of the power controller, otherwise after a while failures may occur: The charge display is incorrect or the charging process starts after a while. Calibration will also help increase the battery life.

How to determine battery capacity

To determine the battery capacity we will use standard means Windows operating system. For this method you will need to use the command line:

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

Manual calibration

You can perform calibration and boost the battery manually, without resorting to additional software. In this case, we will use standard operating system tools.

Before you begin, you need to configure your energy saving settings:

The manual calibration process is as follows:

First, put the laptop on charge and charge it to 100%;
Further discharge to 0% by disconnecting it from the power supply;

Important! When the laptop is discharged to 0%, you should not use it or run any programs, otherwise you will not be able to reset the controller.

After the charge level reaches the minimum value, put the computer on charge again and charge it to 100%. At the same time, it is not recommended to use a PC during the process; this will disrupt the battery reanimation process.

Important! Calibration cannot increase the battery capacity; it does not eliminate physical wear of the battery. Thanks to this operation, the controller begins to work correctly: failures are eliminated, the charge level is displayed correctly, charging proceeds without delay.

Calibration programs

Next, we’ll look at specialized utilities that will help you calibrate your laptop battery. It is best to use the software offered by the device manufacturer, because... they have a specification that allows you to work correctly with the battery.

For Lenovo laptops there is a special utility that allows you to find out the status, restore the battery and perform calibration. The utility is equipped with all Lenovo IdeaPad series laptops.

Battery operation process:

After launch, click on the “ gears» located at the bottom of the utility window;
then a reset warning will appear in a new window, click “ Start» to start calibration. You must first close all running programs and connect the computer to the power supply;
then click " Continue»;
The battery optimization process will begin. It is worth saying that it will take quite a long time. The battery will be charged first and then discharged. The process cannot be interrupted; it is not advisable to use a laptop.

Smart Battery Calibration in Phoenix BIOS

This utility is built into the Phoenix BIOS on HP laptops and devices from other companies. The Smart Battery Calibration utility allows you to check the battery status, run diagnostics and calibrate it.

First, turn off the computer;
then we start the laptop and on the start screen press the key combination to enter the BIOS. The most common combinations are “Delete”, “Esc” and “F2”. The required command to enter is usually displayed on the start screen;
when entering the BIOS, to navigate, use the arrow keys and the “Enter” key to open the desired section;
move the pointer using the arrow keys to the " tab Boot»;

Functional utility for HP laptops. With her help you can check the status all hardware and software elements of a computer. It also carries out a battery diagnostic process and calibrates it if malfunctions in the controller are detected.

launch the program from the desktop;
After starting the utility, in the main window, select the section “ My Computer»;
then we start testing the battery " BatteryTest»;
After this, a window with test results will be displayed. The results may be as follows:
- « Passed» — battery replacement is not required.
- « Perform calibration"—automatic battery optimization starts.

Important! Battery calibration using HP Support Assistant may take several hours and is recommended during periods when the computer will not be used for an extended period of time.

A small program that will allow you to effectively diagnose the battery on any laptop, including Asus, Acer or Samsung. With its help, it is possible to optimize charge consumption, obtain detailed information about the state of the battery, quickly switch between power management schemes, set charge/discharge cycles, and find out the battery life. After installation, the utility is located in the system tray. BatteryCare can successfully replace the Battery Doctor or Battery Calibration utility for a laptop on Windows 7/8/10.

Instructions for working with:

go to “Settings” and to the “ Notifications»;
in the block " Miscellaneous Event» check the “Recommend battery calibration after” checkbox and set the required charging cycle, in our case 25 cycles;
After the recommended cycle has been exhausted, the application will offer to perform automatic calibration.

This utility will allow you to track the battery charge level, assess battery wear, find out the voltage, restore the battery and conduct tests. It will also allow you to find out the equipment manufacturer. During operation, the utility automatically generates a schedule of battery operation and charge/discharge cycles, saving it in a special folder on the hard drive.

Important! The utility is paid, the trial version is available for 14 days. Calibration can only be performed if the program has been purchased.

Instructions:

launch the program and in the main window click on the battery icon;
then several blocks will appear in a new window “ Battery", which displays information about the current state of the battery and "Calibration";
in this section you need to activate the parameter “ PerformCalibration" and "Battery Calibration" to start the process. The operation will be performed automatically.

How to save your battery

for proper battery calibration it is best use special utilities, which are designed for specific device models;
if autonomous operation is not expected, then it is best remove the battery from the device and work from the network. In this case, the battery must be charged at least half to prevent it from entering a deep discharge state. But you shouldn’t constantly use the power supply; you need to use the battery at least once every 5 days;
to extend battery life, it is recommended to connect to the network when the charge level reaches 15-20%;
frequent calibration may cause harm The battery has simply used up extra charge/discharge cycles. It is important to know that cycles are limited and cannot be restored;
If the battery wear is more than 65%, then optimization is recommended to be carried out once a month. This will help extend the service life a little;
In order to save the laptop battery, you need to control the temperature value. The optimal temperature is from +5 to +45, values higher may adversely affect the device.

HP Battery Calibration

Each battery has its own rated life. After it ends, the battery capacity gradually begins to decrease and this is a natural process. As a result, the monitor screen may not display the actual battery charge level. For your HP computer to display the charge level, the HP battery must be calibrated. This article provides three methods for calibrating batteries.

Calibrate using the HP Diagnostic Utility
Calibrating an HP laptop battery using this utility is done as follows:

Unplug the power cable from the outlet and then turn on your laptop.
When HP appears in large letters on the screen, press Esc.
After the Boot item appears, press the F2 button to select system diagnostics.
Next, several tabs will appear: you need to select the Battery Testing tab. It is worth noting that if the battery on your laptop is 100% charged, the battery check window may not appear.
After completing the previous step, plug the power cord back into the outlet.
You need to click on “Start battery testing”. HP battery verification and calibration has begun.

Calibration using HP Support Assistant
This HP laptop battery calibration program allows you to calibrate very quickly and accurately. To use it, you must follow the tips below:
-First click on “Start”.
-Then, under All Programs, select the HP tab - HP Support Assistant.
-A welcome screen will appear in the window that opens. It is necessary to specify the parameters of the program, as well as updates. In addition, here you can enter anonymized information into an HP laptop.
-After this, you need to click on the “Next” button, which takes you to the main page of the program.
-To access the program diagnostic tools, you must click on the “My Computer” button on this page. When it opens, tabs will appear from which you need to select “Diagnostic Tools”, and in it, check the “Check HP Battery” box.
-When you complete the previous step, the HP Battery Check test will start working.
-After checking, the results of this test will be displayed on the screen.

Instructions for calibrating or replacing the battery will also be provided with the test results. Follow these instructions.

Manual battery calibration
Manual calibration is performed in several sequential steps that allow you to accurately display the battery charge level. For example, calibrating the HP Pavilion battery manually is as follows:

First you need to fully charge the battery. To do this, connect the power cable to a power outlet and charge the battery until it is 100% charged. After that, follow the next step.
Now you need to completely discharge the laptop. To do this, unplug the power cord from the outlet, then turn off the laptop, and then press the power key. The laptop will start to turn on, and when HP appears on the screen, you need to press the Esc button. A download window should appear. If the operating system suddenly boots in the usual way, then turn off the computer and turn it on again.
After the required window appears, you must press the F2 button and select the line “System Diagnostics” in the main menu. After that, click on the “Check Hard Disk” line.
Leave the laptop in this position and wait for it to completely discharge naturally.
Next you need to complete the third step, which is to charge the battery. To do this, connect the cord to a power outlet and charge the battery to 100% capacity.
Turn on the laptop in normal mode and move the mouse arrow over the battery indicator in the bottom panel of the laptop.
After the battery is fully charged, do not turn off the laptop for at least two and a half hours.
Now you need to check the battery. To do this, also turn off the computer and press Esc when turning it on.
Next, when you press F2, a menu will appear in which we select “System Diagnostics”.
In this tab, click “battery check”. In this window you see the status of the battery test and can count the time until the process is completed.

If the calibration is successful, the “Passed” message should appear in the verification window upon completion. If there is no such inscription, but “calibration” is written, then this may mean that the battery needs to be replaced.
