How to check the status of the battery on Android? Testing a laptop battery.

Not many users know that the incorrect functioning of the battery may cause a considerable number of problems relating to the work of the computer itself. Therefore, it is very important to follow the status of the battery. If your PC battery does not charge, first of all, check the power cable and driver, and then go to the battery. In this article, consider in detail how to check the laptop battery for performance. Let's deal with. Go!

What are the main causes of problems with a laptop battery? There are quite a lot of them. The most common is banal wear. The battery is not eternal and has a service life (as a rule, 2-3 years) and after its expiration it is not so good. So do not forget about this circumstance. After all, if you have an old laptop, you probably have time to replace the battery for a long time. Akb is consumableswhich can be replaced without any problems.

There are several rules that will allow you to extend the battery life as much as possible. First - remove the battery when the laptop works from the network. Very often, people use laptops as a stationary device, while not removing the battery, which reduces its service life. The second rule is recommended to fully discharge / charging the battery at least once a couple of weeks, and better every week. Otherwise, the problem may begin much earlier than the specified period.

Other reasons for poor battery performance:

There was a short circuit;
The operation of the power controller was broken;
There were problems with the contacts of the AKB;
The nutrition of the motherboard was broken;
Drivers work incorrectly;
The power cable was damaged.

If for some reason you do not want to contact the wizard or in the service center, you can spend independent diagnosis Battery laptop. To do this, you will need to download and install a special batterycare utility. With it, you can see all the basic information on work and the current state of the battery. Also Batterycare offers the user tips and recommendations for improving the operation of the AKB and a decrease in the charge consumed. In general, the program is very useful, while completely free. So be sure to download.

Another excellent utility offering similar features is Battery Optimizer. From the advantages and features you can allocate what Battery Optimizer allows you to increase the time autonomous work Laptop, by making changes to the work of some services. In this case, the program itself tells all this to the user. In addition, here you will find extensive and detailed information on the work of the battery.

You can also do without the use of programs. Need only a multimeter. Move it into direct current mode and connect to the battery, previously disassembled it. Before disassembling the battery, be sure to completely discharge it. To open the battery, insert a knife into a longitudinal case of the case and split the lids. After that, check the voltage in the chain using a multimeter. The display should be displayed equal to the number of batteries multiplied by 3.7. If the voltage of a separate cell is less than 3.7, then this suggests that it is time to replace.

Now you know how to check the laptop battery for performance. Write in the comments if this article was useful for you, share your own experience with other users, and ask any questions about the topic considered.

Let's initially clarify: the laptop attracts us only with its convenience and the fact that it is not necessary to carry a system unit. In the rest important characteristics Often the palm of the championship takes up all the same simple computer. With its mobility, the laptop is obliged to accumulator, which serves 3-4 years. However, when he exhausts his working time, the laptop grows to the outlet. And then the only reason we prefer laptops with desktop computers dissolves. Often interruptions in the laptop functionality occur due to the defective battery operation. The battery can be bad, because there is a possible defect. In this case, you need to check the cord and the current level on the network, after viewing how the drivers work, as they perform important actions in the laptop functionality. Each charging reduces battery capacity, approximately 15% / year. The battery is a consumable, while wear is a completely possible script and this breakdown in a warranty card is not included.

In modern laptops stand lithium batterieswhose average resource is about 400-500 cycles charge-discharge - here as lucky. After the time of the planned operational period, Laptop stops holding the charge and works independently less and less, up to the point that the battery is not able to work without recharging and 1 hour. Accordingly, in this regard, it is decided to replace the "dying" battery. Also, in our head there is a thought: "Is it possible to be aware of how doing the battery of our laptop? Is it possible to foreshadow the time to start his whims with charge? " Our answer is yes, it is possible, and even you need to give your compact electronic friend in a responsible moment graduated from your important activity. There are programs that help users check the laptop battery and keep the owner know all events taking place with the battery of its working device.

What are the programs for this control and that we can control still with their help

There are programs exclusively to check the state of only the battery itself, and there are those that will show you the states of many other elements of the laptop.

You can test the battery status using the regular program of the laptop itself, and you can download special programSix there are many: loading processor and non-loading, paid and free, for Windows and Mac, etc. etc.

"System Information"

This method prefers lovers of tin and those who are used to everything solve standard tools. All that the Mac host is already needed is ready in OS X. The battery check also enters this list.

Look at the "hardware" → "Power supply", and the program itself is to search for Apple → "On this Mac" → "System Report".

Often, problems in the functioning of the laptop occur due to the infallible battery operation. If the battery does not charge, the causes of the breakage should be revealed. Starting with checking cord and voltage in the power grid, then pay attention to the drivers that play an important role in the functioning of the device.

It also may be in damage to the power circuit or connector. If the problem lies here, it is necessary to restore the track paths, it may be necessary and the full replacement is necessary - it is not necessary to do without diagnostics.

If here you have not found problems, then the reason directly in the laptop battery.

Battery does not charge on a laptop: Causes

We note the standard batteries problems.

Probably the most common cause of problems is an elementary physical wear. Batteries on modern laptop models are able to withstand no more than 800 charge cycles.Thus, the device is designed for 2 years, after which in most cases the battery is needed. That is, the life of the battery is average equal to two years, it happens three. After each charge cycle, the battery capacity is reduced, for the year this container decreases by about fifteen percent. Battery - consumable, so this process It is quite predictable and often this breakdown is not even introduced into the warranty card. However, you can extend the battery action by observing simple rules for use: the battery cannot be kept constantly in the device if the laptop works from an external power source - it is necessary to pull it out and stored in a dark cool place;

Important! Perform a complete discharge / charging cycle at least several times a week, otherwise the battery fails very unexpectedly and faster than you can assume.

Also, the reason may wage in the inoperability of one battery in the battery, due to which the entire battery does not function. In this case, the battery is subject to recovery;
Next reason - short circuit;
If the laptop does not see the battery, but the charging goes, most likely the reason for the failure of the controller itself - and this case must be changed by the battery;
If the laptop sees the battery, but charging is not performed, a number of reasons are possible:

Business in battery contacts, they may be damaged, possibly needed cleaning from oxidation;
The battery is incorrectly inserted, remove it and put it again;
Battery resource has been exhausted;
Business in the nutrition of the motherboard;
Drivers do not work;
Damaged cord;
The battery is inoperable, replacement is necessary.

Of course, after detection, the cause of the problem is better to contact a specialist for eliminating it. But you can try and independently rehabilitate the battery.

To begin with, we perform a number of non-hard action:

Turn off the device through the Start menu;
Pull the power cord;
Remove the battery from the device;
Press the power button and keep 20 seconds;
We insert the battery back, load the computer;

If the charge is in the minimum level - we connect an external power supply.

Perform battery diagnostics

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

Consider some popular and pretty efficient programs. But it is worth remembering that the causes of problems are quite diverse, and not always the program will be able to eliminate them. Often, these utilities allow you to extend the battery life, reducing the load.

Monitor the state of the battery, is pretty easy to use, does not slow down the operation of the system. It shows detailed information about the operation of the battery, for example, how much percent has decreased the container. Based on the initial characteristics. You can also find out the number of full battery charge cycles, calibration date. Also, the utility shares tips to reduce charge consumption. The program is free, automatically updated. I think it is worth a download who has not done so yet.

Also pretty famous program To optimize the battery and maximize the operating time. The utility differs from similar to a convenient function - it knows how to report, for how many percent you can enhance the battery life, if you change some services and system services. Changed settings are saved in a personal profile, after which they can easily be opened at any time. The utility makes advanced monitoring of the battery operation, making a loss assessment by comparing with the rated power of the battery. It has a fairly simple and convenient interface, does not require special knowledge to use.

Tests the state of the battery, denotes a real capacity. The program is useful when buying a laptop, used, you can find out in a few minutes, in what condition the battery and how much it will last.

Another similar utility. Reduces power consumption, disconnecting unnecessary processesallows you to work with a computer up to two times longer.

How to troubleshoot the batteries

If there are problems with the battery, you should not immediately go to the store for a new one. It is quite possible to restore it. Of course, the battery capacity is not calculated a certain amount of Cycles, but there are recovery methods.

Consider the decision of the most common problems.

The battery is not charging

It happens, the battery just stops getting a charge. The laptop sees the battery, the charge level is shown in the tray, but when connected to external source No food changes.

What to do?

Let us return the battery setting in the BIOS to the initial values. To do this, perform the following actions:

Turn off the laptop from external food;
Neatly remove the battery;
Press the computer's power button and keep at least a minute;
We connect the device to the power grid, the battery do not insert;
We go to the BIOS: When loading the system, press the keyboard shortcuts that are listed in the user manual. Often it is Del, F12 or F2;
Resetting the settings to the initial value (Restore Defauts), save (Save), exit (EXIT);

Turn off the device, hold the power button 5 seconds;
Pull the cord, insert the battery;
Insert the plug, connect the laptop to an external power source;
Download.

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

Charge comes, but not 100%

The charge goes, however it does not reach logical completion, the battery is not fully charged. Another symptom of "disease" - the battery life of the device for one charge is strongly reduced. The laptop holds a charge several times less than before.

What to do?

There will be some utilities that we considered earlier. Check the battery status of one of them. We need to know the following features: the stated battery power (it is nominal), the maximum power level that reaches the battery today and the percentage of the wear of the battery. Accordingly, the greater the number, the higher the need to replace the battery. If the percentage is insignificant, most likely, the battery is not the main reason for the reduction of autonomous work. Go ahead.

The problem may wage in any program that you have recently installed. It can safely work the background and significantly increase the work of the processor and Wi-Fi, thus closing the transition to saving mode. To check the presence of such utilities, call the manager by pressing Ctrl + Shift + ESC, analyze the work of background programs. Deactivation of unnecessary utilities can increase battery life.

Purchased battery does not function

The reason may wage in incompatibility of the purchased battery with the charging controller. Batteries can be of the same size, but they differ in other characteristics. Try to reset the BIOS settings. If it does not help, compare the marks of the old and new batteries - they should not be different.

Thus, you should not panic at the first battery life failures. And even more so, you should not immediately look for money for a new battery, it is worth it, by the way, quite a few. Try to use our recommendations and execute the actions described. Try to diagnose and restore the battery performance. special utilities or by resetting the system settings. Check the various options and analyze the causes of the breakage. Perhaps everything is not so scary. If you do not neglect the rules of the device, the battery will last long time. By the way, the batteries are quite rare so abruptly fail, more often problems arise in software Or the cause is the power supply unit / connector. Try all the methods, and only then change the battery for a new one.

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

Today we will analyze another popular and frequently asked question: how to find out the degree of wear of the laptop battery. And immediately make the reservation - find out the real wear and battery life will not work in any way - all existing programs allow us to only approximate these values, although it is often enough. We will look at two ways.

Determine the wear by means of Windows

Open Start, in the search we introduce cmd. and on the found file cmd.exe click right mouse button, choosing Run on the name of the administrator. IN command line We enter powerCfg Energy and Zhmem. ENTER.

A minute later, the results will appear, but they will not appear on the screen, and will be saved in the HTML file. For his search proceed here:
C: \\ Windows \\ System32 \\ ENERGY-REPORT.HTML

Open this file From the System32 folder, you probably will not work, so you copy it to any other folder from where you open any Internet.

The report is quite bulky, boldly leafing down and find the section Battery information.

It will indicate the calculated (passportable) capacity of the battery and capacity at the last complete charge. Dividing the last container on the passport can be obtained by the remaining resource: in this case, 36% remained.

Battery wear in the AIDA64 program

To determine the degree of wear, you can take advantage of a well-known program for the diagnosis of PCs. Earlier with its help, we, name, laptop, and so on. Therefore, boldly - this utility will be useful for you more than once.

In the program open the menu A computer - Power SupplyAnd we see the same values \u200b\u200bobtained by the first way using the command line. Here, Aida64 immediately shows the degree of wear - 63%. By the way, it is after 5 years of operation of a laptop, so Windows persistently asks to replace the battery.

Another screenshot for example is a two-year sAMSUNG laptopwhich was used infrequently. AIDA64 shows 26% of worn out and 157 recharge cycles. These figures correspond to the theory that in the first two years the battery loses up to 30% of its nominal container.

If you decide to replace the battery for a laptop, we recommend reading the story of experts service Center about .

Good afternoon, regular readers and blog subscribers! The main advantage of the laptop before system block - This is its autonomy. Work without connecting the device to electrical network Possible due to the use of AKB. Modern laptops have a very wide variation on the autonomy of work - from 3 to 12-13 hours. Over time, many users faced the fact that the laptop is discharged faster and a reasonable question arises - the problem in the battery or it is influenced by something from the outside. To find the answer you should know how to check the battery of the laptop, and I will tell you how to do three ways.

Special equipment

Multimeter is a device that measures current strength. The battery in a laptop is a plastic case inside which batteries are located, each of them has a recharge cycle and with its wear, the current strength becomes less. To check the multimeter, you will need to disassemble the battery. You can do this with a thin knife, inserting it into a longitudinal seam and spreading the lid. Tester It is necessary to translate a permanent current to the value and sequentially check the voltage in the chain. It should be equal to the product of elements of batteries by 3.7. Example: 8 batteries * 3.7 \u003d 29.6. If the value is less, the battery wear is affected on the autonomous working capacity of the laptop.

Built-in

Of course, the use of a multimeter allows you to quickly and accurately assess the degree of battery wear, but if it is not at hand or you are afraid to damage the battery during the parsing, it is better to seek help to software. Option for lazy (do not download and install anything) is the branded utility that is in all windows versionsstarting from 7.

In the "Start" menu, we find the "Run" string and enter the CMD value. Upon this combination, the command line will be found to be opened on behalf of the administrator. Next, enter another command: "PowerCfg Energy". After its activation, the battery status is estimated in Windows 10 and earlier versions. It lasts not more than 60 seconds, and the result is saved to the file, the reference to which will appear on the command line after the end of the test. This is usually the root directory on the system disk. If the file does not open, it should be copied to the desktop.

The file contains a lot useful informationHowever, the most interesting thing is written in two lines from below - the calculated container (that is, the factory) and the nominal (actual at the time of the inspection). It is obvious that the test must be carried out only after the complete charge of the laptop. If the values \u200b\u200bcoincide, the battery keeps the charge at the same level and its fast discharge The consequence of third-party influences.

Useful programs

Use branded windows program Very convenient and fast, but for more details you need to install separate programs.

The best of them are:

battery Care;
aIDA64;
battery Eater;
iMTEC Battery Mark;
battery Optimezer.

Each of these utilities has its advantages, so one is quite difficult to allocate.

Battery Care - free software. Advantages - constantly updated by the creators, has a high accuracy of the battery performance, provides advanced information about the battery, does not require many resources.

AIDA 64 - useful applicationwhich allows you to conduct a comprehensive analysis of the work of a laptop or PC. It displays information not only about the hardware, but also the system itself, as well as the status of the BIOS. The utility is paid, but there is a 30-day trial version. (The one I distribute is an idle license).

Battery Eater - This utility is designed to test the autonomy of the laptop at different loads. In total, there are three test options - simple, reading and classic. In each mode, a laptop is in different ways, which gives a real and accurate assessment of its autonomy during critical loads.

IMTEC Battery Mark - the utility has similarities with the previous one and also calculates the time of operation at different loads. The advantage is - stability of work on old laptop models, especially, relevant for HP and ASUS (which have the most vitary batteries), and also makes it possible to understand how the battery will behave when the voltage changes will behave. Testing takes about 10 minutes, it is not recommended to run anything else at this time, otherwise the assessment may not be accurate. Data is provided in graphic and text form. A similar test is recommended to be carried out with some frequency to have an idea of \u200b\u200bthe wear of the battery.

Battery Optimizer is an excellent application for assessing and setting up a laptop. With it, you can simulate different situations for the device operation and select Settings with best option By autonomy and careful attitude to the battery. These settings can be saved as a template and include as needed. An important advantage is the simplicity of using the utility, even an inexperienced user will be able to figure it out.

In order to obtain a real battery status picture, it is recommended to install several of the programs proposed above and compare the result. If it is to converge in several tests, the accuracy of the data received does not leave doubt. Users who have recently become laptop owners I advise you to familiarize yourself with the recommendations on the use of AKB and install at least one program for the implementation of tests. This will allow you to continue not to face an unpleasant surprise - battery breakdown.

Conclusion

Modern batteries have 2 years of service life, but in fact work without problems 3-4 years. The average number of charging cycles is 400-500. This figure seems very impressive, but in fact the wear is carried out quickly, if not to relate to the device carefully. I do not recommend changing the corrupted battery to the Chinese version, so to save money, time and effort to take care of the extension of the service life from the moment of purchase and then the battery will have to be changed with the laptop itself.
