Battery moon download program for laptop. BATExpert – we monitor the health of your laptop battery. How to test a laptop battery at home

Often problems in the functioning of a laptop arise due to poor battery performance. If the battery does not charge, the cause of the failure should be identified. You should start by checking the cord and voltage in the electrical network, then pay attention to the drivers, which play an important role in the functioning of the device.

It may also be due to damage to the power circuit or connector. If the problem lies here, it is necessary to restore the board tracks, it may also require a complete replacement - this cannot be done without diagnostics.

If you don’t find a problem here, then the problem is directly in the laptop battery.

The battery on the laptop does not charge: reasons

Let's note standard battery problems.

Probably the most common cause of problems is simple physical wear and tear. Batteries on modern laptop models can withstand no more than 800 charge cycles. Thus, the device is designed to last for 2 years, after which in most cases the battery will need to be replaced. That is, the battery life is on average two years, sometimes three. After each charge cycle, the battery capacity is reduced; over the course of a year, this capacity decreases by about fifteen percent. The battery is a consumable item, so this process is quite predictable and often this breakdown is not even included in the warranty card. However, you can extend the life of the battery by following simple rules uses: the battery cannot be kept in the device all the time if the laptop is powered by an external power source - you must remove it and store it in a cool, dark place;

Important! Carry out a full discharge/charge cycle at least several times a week, otherwise the battery will fail quite unexpectedly and faster than you might expect.

Also, the reason may lie in the failure of one battery in the battery, due to which the entire battery does not function. In this case, the battery must be restored;
The next reason is a short circuit;
If the laptop does not see the battery, but is charging, most likely the reason is the failure of the controller itself - and in this case it is necessary to change the battery;
If the laptop sees the battery, but does not charge, there are a number of possible reasons:

The issue is the battery contacts, they may be damaged and may need to be cleaned to prevent oxidation;
The battery is not inserted correctly, remove it and reinsert it;
The battery life is exhausted;
It's a matter of the motherboard's power supply;
Drivers do not work;
The cord is damaged;
The battery is inoperative and needs to be replaced.

Of course, after discovering the cause of the problem, it is better to contact a specialist to fix it. But you can try to rehabilitate the battery yourself.

To get started, we perform a number of simple steps:

Turn off the device through the Start menu;
Pull out the power cord;
Remove the battery from the device;
Press the power button and hold for 20 seconds;
We put the battery back in and boot the computer;

If the charge in the tray is at a minimum level, connect an external power source.

We carry out battery diagnostics

Wondering how to check the battery on a laptop? To diagnose battery performance and determine its level of performance, there are many different utilities. By the way, they sometimes help to increase the service life of the battery.

Let's look at several popular and quite effective programs. But it is worth remembering that the causes of problems are quite varied, and the program will not always be able to fix them. Often these utilities can extend battery life by reducing the load.

Monitors the battery status, is quite easy to use, and does not slow down the system. Shows detailed information about battery performance, for example, by what percentage the capacity has decreased. Based on the initial characteristics. You can also find out the number of complete battery charge cycles and the calibration date. The utility also shares tips on reducing battery consumption. The program is free and updates automatically. I think it's worth downloading if you haven't already.

Also a fairly well-known program for optimizing battery performance and maximizing its service life. The utility differs from similar convenient function- she can tell you by what percentage the time can be increased battery life, if you change some services and services of the system. Changed settings are saved in personal profile, after which they can easily be opened at any time. The utility does advanced monitoring of battery performance, making an assessment of the loss, comparing it with the rated power of the battery. It has a fairly simple and user-friendly interface and does not require special knowledge to use.

Tests the battery condition, indicates the actual capacity. The program is useful when buying a used laptop; in a few minutes you can find out what condition the battery is in and how long it will last.

Another similar utility. Reduces energy consumption by disabling unnecessary processes, allowing the computer to work up to two times longer.

How to troubleshoot battery problems

If you have problems with the battery, do not immediately go to the store for a new one. It is quite possible to restore it. Of course, the battery capacity is not designed for a certain number of cycles, but there are recovery methods.

Let's look at solutions to the most common problems.

Battery won't charge

Sometimes the battery simply stops receiving a charge. The laptop sees the battery, the charge level is shown in the tray, but when connected to external source nothing changes in the food supply.

What to do?

Let's return the battery settings in the BIOS to their original values. To do this, perform the following steps:

Disconnect the laptop from external power;
Carefully remove the battery;
Press the computer's power button and hold it for at least a minute;
We connect the device to the power supply, do not insert the battery;
We go into bios: when loading the system, press the key combinations that are indicated in the user manual. Often this is Del, F12 or F2;
Reset the settings to the initial value (Restore Defauts), save (Save), exit (Exit);

Turn off the device by holding the power button for 5 seconds;
Pull out the cord, insert the battery;
Insert the plug and connect the laptop to an external power source;
Loading.

The method worked if you see a system notification that the battery is charging.

The charge is on, but not 100%

The charge continues, but does not reach its logical conclusion; the battery is not fully charged. Another symptom of the “disease” is that the battery life of the device per charge is greatly reduced. The laptop holds a charge several times less than before.

What to do?

The utilities that we discussed earlier will come in handy here. We check the condition of the battery of one of them. We need to know the following characteristics: the declared power of the battery (also known as the nominal power), the maximum power level that the battery reaches today and the percentage of battery wear. Accordingly, the higher the number, the higher the need to replace the battery. If the percentage is insignificant, most likely the battery is not main reason reduced battery life. Go ahead.

The problem may lie in some program that you recently installed. It can work quietly in the background and significantly increase the performance of the processor and Wi-Fi, thus closing the transition to saving mode. To check the presence of such utilities, call the dispatcher by pressing Ctrl+Shift+Esc and analyze the operation of background programs. Deactivating unnecessary utilities can improve battery life.

The purchased battery does not function

The reason may lie in the incompatibility of the purchased battery with the charging controller. Batteries may be the same size, but differ in other characteristics. Try resetting the BIOS settings. If this does not help, compare the markings of the old and new batteries - they should not be different.

Thus, there is no need to panic at the first battery failure. Moreover, you shouldn’t immediately look for money for a new battery; by the way, it costs a lot. Try our recommendations and follow the steps described. Try to diagnose and restore the battery. special utilities or by resetting the system. Check various options and analyze the causes of the breakdown. Perhaps it's not so scary. If you do not neglect the rules of operation of the device, the battery will last a long time. By the way, batteries rarely fail so suddenly; more often problems arise in the software or the cause is the power supply/connector. Try all the methods, and only then replace the battery with a new one.

Note! When buying a battery, it is better to take with you an old battery or a laptop, so it is more likely that you will be offered exactly the element that you need.

A serviceable and fully charged battery can keep your laptop running for more than 5 hours. If you notice that the battery life of your laptop is greatly underestimated, it would be a good idea to test the battery and determine the degree of its wear. The power supply may need to be replaced soon.

How to test a laptop battery at home

The instructions for using a laptop battery suggest charging it only after full discharge. Regular violation of this rule over time leads to a decrease in the actual capacity of the battery, as a result of which it runs out faster.

To check the capacity of the power element, the number of remaining charge/discharge cycles and some other parameters, you can connect a special device to it - a portable tester for PC. However, this device is characterized by one significant drawback - its high cost (more than 30 thousand rubles), so it can only be found in computer workshops.

Testing a battery at home involves the use of software diagnostic methods, namely:

command line;
additional software.

Determining the degree of battery wear via the command line

To view the current state (charge) of the power supply and the remaining battery life of the laptop, just click on the corresponding icon in the system tray.

However, the data obtained does not allow us to determine the actual battery capacity. In the operating room Windows system 7 and higher, a built-in tool appeared to check the degree of battery wear, which is launched via the command line. To do a battery test with it, you need to:

The file will contain information about the battery manufacturer, its chemical composition, serial number and so on. This data does not provide useful information to you. It is necessary to pay attention to the last two lines: the calculated and actual battery capacity.

The calculated battery capacity (Snach) is the initial state of the battery, that is, the capacity that the power element has after manufacturing.

Last Full Charge (Sreal) is the current capacity of the battery. Using these parameters, you can calculate the degree of battery wear on your laptop. To do this, you need to use the formula: (Snach-Sreal)/Snach. For example, if the factory capacity of the battery is 40,000, and the actual capacity is 30,000, then the degree of wear will be equal to: (40,000-30,000)/40,000 = 0.25 or 25%. The condition of such a battery can be considered normal.

Testing a laptop battery using additional software

If for some reason you were unable to check the battery health using the command line, you can use special software. There are many programs on the Internet that allow you to test your laptop battery. The most popular application is AIDA 64.

Battery testing using AIDA 64 is performed as follows:

After testing the laptop battery, you can draw conclusions about its suitability - will it continue to be used as an autonomous power source or is it better to replace it with a new one.

BATExpert – free utility for those who are used to monitoring the health of their laptop. Over time, a laptop battery may fail or stop working correctly. If necessary, BATExpert will recommend replacing the battery and will show its true state in the “here and now” mode.

By running the program, you will receive complete information about your laptop battery: degree of wear, exact time work from the current charge, its type and temperature, information about charge cycles, manufacturer and some other data.

The program does not require installation and is friendly to most batteries. That is why it is recommended to download BATExpert to owners of not only new, but also very old laptops - the application will find a common language even with them.

Features of the BATExpert program:

Small size (the program archive does not exceed 1 MB).
Ability to clear battery manufacturer data.
