Program for asus laptop battery. How to calibrate a laptop battery - the best programs and standard system tools

There are a huge number of different recommendations and other tales floating around among users that allow you to extend the battery life. But what is most interesting is that a lot of this is based on the source of OBS - one grandmother said :), that is, advice that is not substantiated in any way, as a rule, is not effective and even dangerous. At the same time, such recommendations often begin to contradict each other and are still passed on, articles are written, and others are written from them...

But in fact, there are no secrets that scientists were silent about and there is no secret in the operation of batteries, so dancing with a tambourine is cancelled. Battery operation is based on the most common laws of physics and chemistry. In order for this element to work stably and last as long as possible, you need it calibrate correctly and adhere to basic rules during operation, depending on the battery type.

What types of batteries are there in laptops?

There are several main types of batteries you can find in everyday life. Depending on the type, they are marked with the following designations:

• NiCd– stands for nickel-cadmium battery;
• NiMH– common nickel-metal hydroid batteries;
• LiIon– even more popular lithium-ion batteries;
• LiPol– lithium polymer batteries.

They all differ in both their properties and characteristics. At the moment, most often you can stumble upon lithium-ion batteries. They are used everywhere, including in laptops.

The main advantages of such batteries are their compact size, relatively light weight and lack of memory effect. Everything is great, but unfortunately, improper use of such batteries can ruin them very quickly. Especially often, people use operating methods intended for NiMH batteries, which generally differ in every way from lithium-ion batteries. As a result, an expensive battery soon turns into useless garbage and the laptop owner begins to ask the question:

It is very important to understand that different types of batteries require different approaches, even if they are just going to sit on a shelf and collect dust samples.

Battery calibration

What is it and why is it needed? Everything is very simple, and most likely many have already heard something about this method - we fully charge the battery and then completely discharge it

There is a misconception that in this way the battery is “trained” or its capacity is increased. But the reality looks a little different: the battery controller records the minimum and maximum charge values ​​and corrects the statistical measurement error. This is necessary to ensure that the data on the battery charge level is as objective as possible.

So, after such a procedure, the battery wear indicator can move either for the better or for the worse. But this does not mean at all that the battery has worsened or become better, just that the data on its charge has become more accurate.

It should be taken into account that the error can still reach up to 10%. Because in reality there is no charge level inside the battery, all these indicators are calculated purely statistically and with a certain percentage of inaccuracy.

When the laptop battery is brand new

You have a new device, a laptop or a phone - it doesn’t really matter, the main thing is that it has a lithium battery. Most likely, it will already be partially charged and the device can operate from it.

To begin, fully charge and then fully discharge. But already at this stage, most users make a grave mistake: they completely discharge the battery from the beginning, and then only begin to fully charge it. This is the battery's first step towards recycling, so don't do it.

Why is this bad? Because the controller has not yet been calibrated properly and there is a risk of overdischarge, which worsens the properties of the new battery. So, first of all, start charging it fully and only then, let the device discharge until it turns off, and then charge again. After such a basic procedure, charging can be done at your convenience.

Usually, equipment sellers, after purchase, begin to give a ton of recommendations on how to “activate” the battery with long-term charging, how to “boost” it. But they are wrong about everything. There is no need for the so-called “activation” (even this term is not used by anyone except sellers), because when purchased, it already has a charge and is ready for use.

“Rocking up” will also not bring anything good. If someone enthusiastically tells you how they “boosted” the battery and it began to work longer, then just silently listen to this person, but don’t do this yourself. Even if the battery really began to hold a charge longer, this only indicates that it was previously used incorrectly.

Any battery will hold exactly as much charge as it is physically (and chemically) capable of holding. There is no way it can be expanded, stretched and enlarged; it is not capable of that.

But the charge controller is capable of storing incorrect values, as well as a bunch of different errors, after experiments with “swings”. In general, even battery manufacturers themselves prohibit doing such things with their products.

But do not forget, we are now talking only about lithium batteries; if you use a metal-hydroid battery, then the build-up will really make some sense.

What is a battery controller?

This is a small microcircuit that controls the charge (or discharge) level, voltage and temperature values, and determines when to turn off battery charging. A fairly reliable part that almost never fails. So you can’t blame the controller too much; it is rarely the culprit of malfunctions. Sometimes, some “good” craftsmen use such an “excuse”, saying that the controller has flown. Although this may not be true at all.

We calibrate the battery correctly

As mentioned above, the essence of battery calibration is to fully charge, then fully discharge, and then fully charge again. There is nothing complicated here. Many laptops have a battery calibration function in the BIOS settings. In principle, it is no different from the manual process. But when setting up the controller manually, you need to monitor the discharge of the laptop, because most laptops, when the charge is low, do not turn off, but simply go into hibernation mode and in this case a complete discharge does not occur. To prevent this from happening, you need to disable hibernation, then the battery will be discharged to the very minimum.

Calibration in the BIOS occurs using a parameter (this name may differ for laptops of different models, but the essence is the same). This item can usually be found on the tab power(power management). Sometimes it comes across in other sections, for example, boot or advanced.But if you couldn’t find such an option in the BIOS, then this won’t be a big problem. Because you can easily and simply do everything manually. We do it this way:

1. We put the laptop on charge and fully charge it.
2. After charging, unplug it from the network.
3. We use the laptop until it is completely discharged, until it turns off.
4. We put it on charge and fully charge it.

And that's all! You no longer need to make any body movements. After this procedure, you can continue to use your laptop as usual.

How often should calibration be performed?

There are some users who generally calibrate the battery every week. But you shouldn’t follow their example, this will only reduce the life of your battery. If the battery is working quite normally and your screen displays quite adequate charge values, then there is no particular need for calibration. The battery life is limited by the number of charges and discharges, so such frequent procedures will only wear it out in vain. In some cases, recalibration may be required no more than once every six months, and this will be quite sufficient. If the laptop battery rarely charges to the very end, then you can do this a little more often. But still, no more than once every two months; it’s not worth driving the battery again and wasting its resource.

There is no such need at all. If the battery is only slightly discharged, it can still be safely charged. It is only NiMH batteries that need to be completely discharged and charged, otherwise they reduce their capacity. But you don’t have to do this for LiIon batteries. Here, on the contrary, it is not the duration of the charges that is important, but their quantity. Whether full charging or partial charging, they have the same effect on the battery. The battery lives stably for from five hundred to a thousand charge-discharge cycles, then it begins to significantly lose its capacity.

In general, lithium batteries do not like complete, deep discharge. So try to avoid this. If you don’t even charge a completely discharged battery for at least a week, it will begin to age, lose its capacity and even completely fail. And then you will have to take everything in for repairs.

In the figure below, you can see a graph that shows the change in battery capacity (in this case for mobile phones), depending on the number of cycles.

As we can see, after five hundred cycles, the battery already has only 80% of its original capacity. It happens that this value occurs much earlier. In general, the calculation is that the battery should serve the device consistently for the first year, and then whatever happens.

By the way, the ambient temperature plays an even bigger role here. The colder it is, the less current the battery produces, and self-discharge increases. In such cases, it is best to bring the battery temperature to room temperature. And in the cold, condensation can form and lead to failure of the charge controller.

Take a look at the graph below to see how temperature affects the current output of a battery.

Please note that when the temperature begins to exceed +20 degrees, the capacity also begins to decrease. From this graph you can determine that it is best to use the battery in the range from 0 to +30. Within these limits, the change in capacity is practically not felt. At the same time, if few people will work on a laptop in cold weather, then in hot weather this is a common thing, and when it also heats up under load... In general, think about additional cooling on hot days.

Is it worth removing the battery if the laptop is always running on mains power?

This also makes no sense. In addition, the battery will always serve as an uninterruptible power source and in the event of a power outage, you will not lose unsaved documents and can safely continue working. When a fully charged battery is in a laptop, it is not constantly charged, and there is no constant resource consumption.

The battery's capacity is still lost, even if it is not used. With active use - to a greater extent, with constant operation from the network - to a lesser extent. But in any case, the capacity goes away.

There will be no point in disconnecting the battery in this way only if you really don’t use it for a very long time. When you don't need protection from sudden power outages.

In other cases, it’s better not to even bother. Nothing lasts forever in this world, and one day the battery in your laptop will also stop holding a charge. And there is no way to fix this; here you can only install a new battery.

How to properly store a laptop battery?

If you still decide to keep your battery, then it should be stored at room temperature (even a lower temperature will do, just don’t try to put the battery in the freezer). In this case, the charge level should be within 35-40%. In this way, you can preserve your battery for as long as possible (as far as possible) with minimal loss of capacity. In any case, when it sits for a long time, its capacity will decrease. This phenomenon is called “self-discharge”. For a molded battery it can be approximately 5-10% per year.

As you can see, the battery will not last indefinitely. The main thing is that the battery is not fully charged or, on the contrary, discharged. The latter is especially dangerous. If over-discharge occurs, there is a high probability of losing the battery forever. Remember that we are only talking about lithium batteries here.

Maximum capacity at 65% - how bad is that?

There's really nothing terrible here. Although it all depends on the newness of this battery. For example, if the capacity drops below 80% during warranty, then this is a warranty case, and you can replace yours with a new one. Nowadays, the warranty period for batteries is almost always within one year. So don’t drag your feet if something is wrong and rush to replace the faulty part.

Moreover, services also have very tricky rules. If you do not have a warranty card for the battery, then the warranty starts from the date of manufacture. Who knows how long it was lying on the warehouse shelf? In general, there is no need to drag out time here.

Do programs work to increase laptop battery life?

There are no programs that can physically extend the life of batteries. As a rule, such utilities simply reduce the power consumption of the laptop by turning off everything that seems unnecessary to the program. For example, USB ports will be disabled, the screen backlight will become dimmer, the system design will become simpler, and much more in this spirit.

Yes, it’s true that the operating time on a single charge can extend. But you can achieve this yourself by turning off all unnecessary things yourself.

The developers of such software love to advertise it with loud words, about how this miracle program revives batteries, makes them work in a way that they didn’t even work when new, and much more. But there is nothing so true here that one could really install such a program. All these are fictions and enthusiastic fantasies of developers, whose goal is to attract new users. Here even a negative effect is possible, because it is unknown what else can be installed with this program.

This situation often began to occur when users began to switch en masse from Windows XP to Windows 7. This does not happen on new laptops, and in general this problem gradually disappeared and now practically does not occur.

Users blame Windows 7 for the reduced battery capacity. But the problem here lies not in the system, but in the battery itself. Most likely, such a low capacity already existed and the new system simply displayed real wear indicators.

There is another version - the system itself displays the level incorrectly and wastes resources. However, Microsoft denies such statements. And this problem has practically ceased to appear. Perhaps, if there was a bug, it was fixed, but just in case, still regularly receive the latest system updates so that there are no problems.

A little about the safety of lithium batteries

There is a huge amount of information floating around the Internet about the dangers of lithium batteries, whole stories are posted about how they ignited and even exploded. But you shouldn’t be afraid of batteries; all of the above happens extremely rarely and not without reason. Currently, batteries are manufactured using normal, modern technologies, which are designed to reduce this to a minimum, unless, of course, they are cheap Chinese products.

When working with batteries, follow simple safety rules. They should not be overheated and contacts should not be shorted; they are afraid of moisture. Don’t even think about taking anything apart, much less piercing it!

If you use the battery for its intended purpose, it is in the laptop all the time, no one picks it or does any experiments - then you can rest assured that there will be no problems here.

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:

1. Unplug the power cable from the outlet and then turn on your laptop.
2. When HP appears in large letters on the screen, press Esc.
3. After the Boot item appears, press the F2 button to select system diagnostics.
4. 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.
5. After completing the previous step, plug the power cord back into the outlet.
6. 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 need to 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.

Over time, the capacity of the laptop battery decreases and you have to install a different power source. But if you know how to calibrate your laptop battery, you can extend its life. The chemical processes will not stop due to calibration, but the charge level will be displayed correctly, which also matters.

Why is calibration needed?

In the system settings, a discharge limit value is usually set, upon reaching which the laptop goes into sleep mode - 10%. When the system sees that the charge is 10%, it will turn off the laptop. In this case, the actual charge can be much higher (30-40%).

The controller incorrectly determines the battery volume and believes that it is on its last legs.

To eliminate this drawback, it is necessary to calibrate the battery several times a year, that is, remind the controller of the real maximum and minimum charge level. To accurately determine whether calibration is necessary, use the built-in battery health diagnostic tool:

1. Open a command prompt with administrator rights.
2. Run the command “powercfg.exe -energy -output C:noutbook.html”.

The value “С:notebook.html” determines where the diagnostic report will be saved. In this case, a text file named notebook.html will be sent to the root of drive C. You can specify a different name and save location.

Once the diagnostics are complete, go to the C drive and open the report. It is executed as an HTML file, so its contents can be viewed through any browser. You need to find the “Battery Information” field, which indicates the battery code, manufacturer, chemical composition, number of discharge-charge cycles, estimated capacity, last charge and other parameters.

To determine if your battery needs calibration, compare the estimated capacity to the last full charge. If the readings differ significantly (by more than 15%), then the battery must be calibrated. You will not be able to make the last charge equal to the calculated capacity for the old battery - the flow of chemical processes cannot be reversed, the battery capacity is constantly decreasing. Calibration is needed so that you see the real charge level, no matter how small it may be.

Automatic and manual calibration

The calibration procedure takes several hours, during which the laptop will not be able to be used, so it is better to leave the laptop overnight. Most often, you can calibrate the battery using the built-in utility that the manufacturer preinstalls on the laptop. For example, on Lenovo laptops you will find an Energy Management utility for battery management. How to work with it:

During the calibration process, the laptop will be fully charged, then discharged to zero and charged again to 100%. At this time, you cannot run other programs, turn off the laptop or close its lid, sending it to sleep or hibernation.

If there is no calibration application on the system, try universal utilities such as BatteryCare or Battery Eater. They work on the same principle, discharging and charging the battery.

On some laptops, a calibration utility is built into the BIOS. For example, on HP laptops with Phoenix BIOS, the application is called Smart Battery Calibration. You can find it on the “Boot” tab.

The location of the utility may vary depending on the laptop manufacturer and BIOS version, so it is recommended that you carefully study the manual for your laptop model to make sure that you even have the necessary software.

Manual calibration

The calibration procedure involves completely discharging the battery and then charging it to 100%. You can perform these manipulations without programs. It is enough to solve one problem - the laptop goes into sleep mode when it reaches a certain low charge level. To do this:

The created meal plan will be selected automatically. Now your task is to completely discharge the battery until the laptop shuts down from lack of power. After turning off, connect the laptop to an electrical outlet and wait until the battery is 100% charged. Calibration is completed, now the system will show the real charge level, which will allow you to use the available battery capacity more efficiently.

Programs and utilities for calibrating a laptop battery

To improve the operating efficiency of a laptop battery, it is advisable to periodically calibrate it. This can be done manually, using special programs, as well as through utilities in the BIOS. As you know, a laptop battery consists of a controller (chip) and individual batteries connected in parallel and/or in series. The controller monitors the charging and discharging process of the battery cells. The problem here is that during the operation of the battery, the controller data begins to diverge from the actual state of the cans. As a result, the laptop may “go offline” even when the battery is charged. The battery cannot be used under such conditions and requires calibration. Calibrating a 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 battery charge data of the battery controller does not match their actual state. Let's give a simple example. The charge level of the battery packs is 90%, and the controller has information about their charge at 70%. As a result, when the controller sees 10%, it will send the laptop to sleep mode. 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.

This is a situation where the battery “remembers” the state of charge when connected to the mains, and then releases its charge to this point. As a result, the laptop battery capacity is not fully used.

Battery calibration programs help correct this situation. All modern laptop models use lithium batteries and they do not have the “memory effect” that batteries have.

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

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

Launch Command Prompt with administrator rights. For those who have forgotten how to do this, type cmd.exe in the Start menu and using the context menu, launch the command line on the laptop as the computer administrator.

At the command line, type the following:

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

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

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 received report, we are interested in the section called “Battery Information”. There you need to pay attention to the calculated capacity and the value at the last full charge of the battery. This section will also indicate your laptop's battery type.

As you can see, the last full charge shows a capacity significantly less than the nominal one. A message is even displayed stating that the last charge was carried out at less than 50% of the battery capacity. In this case, you need to use programs and utilities to calibrate, or, more precisely, recalibrate the laptop battery.

But it should be remembered that calibration is not a cure-all. 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 errors in determining battery capacity.

What programs are there to calibrate a laptop battery?

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

HP laptops

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

On the page that appears, you will need to click “Start battery testing”. A scan will be launched and will take some 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 you need to 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 utility's operating parameters and prevent the window from appearing during subsequent 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 some time, and upon completion it will display the results of the battery test. Below you can see everything in the photo.

Lenovo

For Lenovo laptops, you should use the Energy Management program to calibrate the battery. Most Lenovo Idea laptop models are equipped with an Energy Management utility designed to manage power supplies. 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.

Often, due to improper charging, the laptop battery fails. At best, it will show the wrong percentage of charge; calibrating the battery will help here. In the worst case, the battery will completely fail, where only its replacement will help. Therefore, to improve its performance, today’s article will talk about how to calibrate a laptop battery.

I once talked about how to properly charge a laptop battery, be sure to read it, following the rules listed in that article will help your battery last longer.

When is it necessary to calibrate the battery?

Battery calibration should be done when your laptop begins to show an incorrect charging percentage, for example, it shows 90 percent, but turns off very quickly, like after 20%.

This happens due to the “memory effect” of the battery, it remembers the charge level and it appears as if the battery is fully charged, but in fact, the charging was turned off much earlier than its end, and the battery remembered this as a full charge. Nickel batteries (NiMh, NiCd) have always had problems with memory, but as practice shows, lithium-ion (Li-Ion) also suffer from this, although not so much. I remember that many claimed that lithium-ion batteries are not subject to the memory effect, apparently not true. Excerpt from Wikipedia:

Researchers from the Swiss Paul Scherrer Institute, together with colleagues from Toyota Research in Japan, have discovered that a widely used type of lithium-ion battery is still susceptible to a negative “memory effect.”.

In general, calibration should be done approximately once every three months, for preventive purposes; this is quite enough for the normal operation of your laptop’s battery.

How to calibrate a laptop battery.
In principle, there is nothing complicated, the only thing is that the process itself can be very long.

Some laptops, such as Asus, have built-in utilities in the Bios to calibrate the battery. But in this article we will talk about another method that is suitable for any device. Now let's take a closer look at how to calibrate the battery.

Before starting the process, you will need to disable the automatic shutdown of the laptop and the transition to sleep mode (hibernation), which is carried out at a certain percentage of the remaining charge. Let's say this is 10%, then the battery will not be completely discharged, in our case we need a complete discharge, down to 0%. You can disable this by going to Start > Control Panel >
Hardware and Sound > Power Options and set it to “Never”.

The next step is to fully charge the battery, up to 100%.

After this, you need to disconnect the laptop from the network and discharge the battery. You can do this quickly, for example, by playing some computer game, you can also increase the brightness of the screen, which will help drain the battery faster.

And now, the battery is discharged, the laptop has turned off, now you need to fully charge it immediately, you should not leave the battery discharged for a long time, this can damage it. While charging, the laptop must be turned off.

Here it is, simple battery calibration process laptop. Everything should work out for you if you did everything exactly like this. But, if your battery has not been calibrated, then it may already have to be replaced.

A few more tips for using the battery:
Avoid direct sunlight. The optimal temperature for storing the battery is +10°C - +35°C.

I repeat once again that you should not store the battery completely discharged - this will lead to certain death for your battery. Also, you should not leave it for storage outside the laptop when its charge is 100%; the optimal charging percentage for storing the battery is approximately 50%. So you can easily forget about it for several months.

Proper operation and timely calibration will prevent your battery from failing ahead of schedule.

That's all for now. If you still have questions, feel free to write to me at,
