Charging does not work on a samsung laptop. Problem: The battery on the laptop has stopped charging. Not fully charged.

Laptops are, above all, quite compact mobile devices. In other words, these are computers that can be carried around. However, they instantly lose their mobility when the battery stops charging. Today we will tell you what to do if the laptop battery is connected but not charging. Fortunately, it is not always the case that the problem has to be solved by replacing the battery — often because of system errors, third-party software, or even problems with BIOS settings. In any case, we will try to help you save money on purchasing a new battery.

Problem with the charger

To begin with, we suggest you check the s / y itself. Quite often, many in a hurry forget that sometimes the problem may lie in the charger. You can check it literally in seconds, if you have a second c / y home, a laptop with exactly the same connector and working battery. But what if none of the above are present? Then we invite you to do the following:



Well, in this case, s / y, as the cause of the problem, we can exclude. What else could have a detrimental effect on battery charging?

Remove third-party software

Few people know that third-party software can cause this confusion. In principle, the same remark is valid for official software - an error can creep in everywhere, which will not allow charging the battery when the charging is connected. So, let's see how to remove the software:

As you can see, there is nothing difficult in this - a few simple steps and you get a newly earned battery.

If this method did not work, and you are sure that the laptop battery is properly connected but not charging, we have to upset you - the problem is hardly related to the operating system and software. Most likely, without buying a new battery will not work.

I would like the laptop to always serve faithfully, but this can happen: you notice with horror that the battery on the laptop is not charging. As variants of this problem, and solutions may be several. Below I will list all the popular causes of problems with charging a laptop, and also tell you how to deal with most of them on my own.

If you decide to perform diagnostics, then first I ask you to read the article until the very end, so that you know what methods are described here. While reading, you can perform the simplest options to solve this problem. If it seems to you that some option is difficult, then write it down on a piece of paper, so as not to hurry the laptop in a hurry.

Power problem

Perhaps the most frequent problem is a power failure. Start checking this version from the outlet. To do this, you can simply connect the power supply from the laptop to another, obviously working, outlet - and, perhaps, the problem will be solved by itself. If this does not happen, there is nothing to do with food - we continue to search.

In the event that the laptop is connected to a power filter (or as it is called tee), then unplug the power supply from the power filter and plug the laptop directly into a power outlet. It is possible that the tee failed and therefore does not charge the laptop. You can also check the outlet in a fairly simple way — plug your phone or any other device into the outlet and check if the outlet is performing its function.

Broken connector or problem with the controller

The next weak point in charging a laptop is the connector to which the power supply connects. It often fails or simply becomes loose, and contact with the power supply becomes unstable. Try moving the power plug into the laptop connector. If the mobile computer gives any identification marks about the appearance of charging - congratulations, the problem is found.

But do not try to replace the power connector of the laptop yourself, better contact the service. Of course you can disassemble the laptop (by the way, if you need to disassemble the laptop, then the article: “” will be a good helper for you in this procedure), look at the situation from the inside, but there are some nuances that may affect the repair of the connector. For example, in some models of HP repair of such a connector is not done (need to be changed), and if everything is not so bad, then soldering this component of the laptop will help.

This is how the laptop's power connector is replaced:

We found out that the connector is in perfect order - it fits tightly and does not hang out, but charging still does not go, and even the laptop does not show any signs of life and does not blink diodes. Most likely, the power controller is covered - a microcircuit responsible for the power and charge of the battery. It can only be repaired or replaced by qualified personnel.

Inspect contacts in a laptop or reset settings

As part of the search for the reason why the laptop is not charging, you need to check the contact of the battery. It often happens that the contacts are oxidized or clogged, or the locks holding the battery in place become unusable. To check this version, turn over the laptop (of course, off), disconnecting it from the network beforehand. On the bottom surface closer to the screen you will find the battery, which is usually fixed with two latches. They need to be moved to the "open" position (often there is an icon with an image of an open lock next to it), then pull out the battery.

Inspect carefully the contacts of the battery and laptop, if they are clogged - try to clean, then return the battery to its place. These manipulations often solve the problem of charging.

By the way, after turning off the laptop from the network and removing the battery, you can try the so-called hardware reset of the laptop settings. To do this, you must turn off all devices that are connected to a laptop, then press and hold the power button for a minute. Thus, we reset the residual power, "zeroing" the probable error.

After that, release the button and make two or three short presses on the power button. Then you can connect the battery and try to turn on the laptop. This option is simple and effective. Very often, this method helps with the problem.

And one more thing: try to turn on the laptop by connecting the power supply to it, but removing the battery. If the laptop works fine in this mode, and also if the laptop shows with the battery connected, that the “battery is missing” or something like that, and is not charging - apparently, the battery ordered to live a long time. The resource of the battery is limited, depending, of course, on the conditions of use, but often it is 500-1000 charge-discharge cycles. By this turn, the battery begins to lose capacity at an ever increasing rate.

Utilities Battery Care and AIDA64

You can check the status of the battery using free software: Battery Care. The program can be installed on all popular versions of Windows, at the moment - Windows 10, 8, 7, Vista and XP. Of course, this option is not suitable for everyone, so you must first turn on the laptop to do the test (you can connect your battery to a working laptop and make diagnostics on another laptop). During the installation of the program, the installer may impose to install additional programs, in this case, refuse to install these programs (by unchecking the box and clicking "Next"). After installing the program, start it (when you open the program, it will be in the tray - where the clock is). Next, go to the Advanced tab.

To understand how things are with your battery, you need to pay attention to three parameters:

• The claimed capacity is the “capacity” of the new battery, from the factory;
• The maximum charge is the current battery capacity;
• Battery deterioration - how much the battery capacity has decreased compared to the original.

The higher the indicator "Battery Wear", the closer the need to replace the battery, if, of course, you need autonomous operation of the laptop away from the outlet. For example, in this case (picture above), the battery has more than 50% of wear and this means that the battery is discharged 2 times faster than a new battery.

Another application for assessing the status of a PC, including batteries, is AIDA64. Having installed and opened the program, select the “Computer” item on the left and then click on “Power Supply” - and all interesting information about the status of the laptop battery will appear to your eyes.

If you look at the degree of deterioration in the two programs - Battery Care and AIDA64, then we will see that the data is almost the same 56-57%.

Note: in order to maintain battery performance and capacity longer, it is necessary to remove the battery and work from the mains when working at home at all times.

If your battery still has become unusable, then when buying a new one, remember - the marking on it and on the old battery should match. Ideally, bring a laptop with you to the store and test it on site.

Software reasons for laptop failure

Let's start with the most "deep" operating system of any computer / laptop - BIOS. It so happens that it fails, and the laptop begins to "act up." To reset, you must:

1. Remove the battery, disconnect the power supply and all peripheral devices.
2. Press and hold the power button for about a minute.
3. Connect the power supply and turn on the laptop (the battery should remain aside).
4. Enter the BIOS (this is usually done with the Del button, F2, F12 - depending on the manufacturer).
5. Perform a full reset to factory settings. BIOS versions are different, but, whatever you have, you need to find one of the items: “Restore Defaults” or “Load Setup and the like. If you do not find this item, try to find the documentation for your motherboard to deal with this issue.
6. Select the desired item, press "Enter".
7. If the computer does not start to reboot, then save the changes made by selecting “Save and Exit” or press the “F10” key.
8. After these actions, the laptop will restart, but when it starts to turn on, hold down the power button for 10 seconds (this way you turn it off).
9. Next, unplug the power supply and insert the battery into the laptop. Now insert the charge and turn on the laptop by pressing the on / off button.

Removing excess software

It so happens that the process of charging the battery is not controlled by the operating system, but by an additional application. Typically, such applications are pre-installed by the laptop manufacturer, but can also be installed by the user. The problem may be hidden in the incorrect operation of the program: for example, it contains certain settings for the battery life, and it does not allow the batteries to fully charge after a certain service life.

Or another option: there are utilities of the manufacturer, which provides the mode "Best battery life". In this mode, the battery may last you longer, but often the reason that the laptop does not charge, lies here. In any case, modern operating systems are equipped with reliable built-in charge control. Therefore, if you suddenly notice that the battery icon in the tray (the taskbar sector on the right side, where the clock and notification icons are) is different from the standard one, try to find the corresponding application and delete it. To do this, go to the "Control Panel" - "Uninstall programs" and carefully look at what programs are installed on your laptop.

The laptop is quickly discharged

It is also possible that the battery capacity is close to the original, but it still does not suffice for a long time. Most likely, the charge is actively consumed by background applications. To verify this, start the Task Manager (by pressing "Ctrl" + "Alt +" Delete ") and see what is currently running on the laptop. You can also use another option to log in - right-click on the taskbar and select “Task Manager”:

If you sort the tasks in the list by the “CPU” column, you can determine which applications are actively “loading” the laptop and are not currently being used by the user. To do the sorting, left-click on the "CPU" at the beginning of the column. If you close suspicious programs ("Remove the task"), you can extend the battery life of the laptop.

Well, if the options that are described here did not help you, then advice is to go to a computer store or service center to check how the laptop with the new battery will behave.

If the above described methods did not help you to resolve the issue - when the laptop is not charging, then there are 2 options that I can advise. The first is to try installing another battery or the second is to contact a service center who can test your laptop with special equipment and find out what the problem is.

This is how repair is done in the service center:

For any laptop, the battery is a vital element. Of course, you can work from the network, but in this case, the main advantage of a laptop is mooted - mobility. In fact, the battery itself is quite an interesting thing, shrouded in many rumors and myths. Therefore, in order for you to better understand the subject of conversation, here are some facts.

The most common problem is the physical deterioration of a lithium-ion battery or aging. Each time the battery is charged and discharged, a so-called cycle occurs. Modern batteries can withstand several hundred of such cycles, but after each of them the capacity of the battery gradually decreases. This is due to chemical processes occurring inside the battery. But this is not the most interesting.

Even if you don’t use your laptop at all, in two years the lithium-ion battery loses about 20% of its capacity, so it’s foolish to stock Li-ion batteries for future use. Also, when buying, you should pay attention to the production date - batteries released 1, 2, 3 years ago will no longer have the stated characteristics (their nominal capacity will be 10-30% lower, respectively, and the battery life of the device from such a battery will decrease).

Has the laptop battery stopped charging?

If the laptop battery is no longer recognized by the operating system, or it reports that the battery is not charging, this most often indicates a conflict between software and hardware. To solve the problem, you can use two simple ways.

1. Turn off the laptop
2. Unplug the power cord
3. Remove the battery from the laptop
5. Insert the battery in place.
6. Turn on the laptop

After loading Windows, the usual charge icon should appear in the tray, and when the power cable is connected, the charge process icon will appear. If the situation has not changed, try resetting the BIOS settings by running the following algorithm.

1. Turn off the laptop
2. Unplug the power cord
3. Remove the battery from the laptop
4. Press and hold the power button for 30-60 seconds
5. Connect the power cable
6. Turn on the laptop (without battery) and enter the BIOS
7. In the BIOS menu, perform a reset and save the changes.
8. Turn off the laptop by holding the power button for 5-7 seconds
9. Unplug the power cord
10. Insert the battery in place.
11. Plug in the power cord and turn on the laptop

After the operating system is loaded, the icon with the message “plugged in, charging” should appear in the tray. If all the same nothing has changed, most likely, the matter is no longer in software.

What does a laptop battery consist of?

The battery may have really died and needs to be replaced. But before making a final diagnosis, service center experts advise you to check whether the contacts are oxidized, whether the power board is broken, or if the battery controller is out of order.

Connected but not charging laptop, fairly common among users of these mobile computers. The reasons may be different. However, what to do if everything seems to be connected, but the laptop is not charging? We will try to answer this question in this article.

Introduction

Over time, technical devices such as tablets and smartphones, as well as laptops, tend to become unusable. The first manifestation of the fact that the device began to pass, in some cases is incorrect and unstable operation of its battery. That is, you seem to have connected all the wires and the charger, there is a current in the electrical network, but nothing happens. “Why is the laptop not charging?” - such a question arises in such a coincidence of circumstances instantly.

In outline

It is worth noting that such a state is for the battery of any device - be it at least a netbook, at least an ultrabook, even a laptop - is simply inevitable. A neat attitude and calculated load can extend the battery life, but you can not make it eternal. Therefore, we are facing not so much the task of prevention as the need to answer the question of why the laptop is not charging.

Why is this happening? What does this type of breakdown depend on?

It all depends primarily on how often and intensively used the device itself. That is, we are talking about offline battery operation. The more often you use a laptop without connecting to a power source (mains), the faster the drive will become unusable, which will lead you to the solution of this problem. Now we will try to answer the question of why the battery on the laptop is not charging.

Part Verification

To proceed to the resolution of any problem, it is first recommended to establish the cause that caused it. Similarly in our case. Before you grab the tools and look for instructions on how to restore the battery, make sure that the problem lies in its unstable work. Only then look for the answer to the question why the battery on the laptop is not charging.

So how to determine the nature of such a kind of breakdown, if you can call it that? To do this, turn on the laptop. If it starts up, the device and the operating system will function successfully, and when you connect the charging process to the working electrical network, you will not see the charge, then 99.9 percent will be allocated to the breakdown of the battery. In this case, you have a direct route to information sources that tell you why the laptop battery is not charging and how it can be fixed.

If the device in general categorically does not want to start working, then the point here, most likely, is not in the battery. Check if there is power in the electrical network. If there is, then perhaps the problem lies precisely in the power supply unit installed in the laptop, as well as in other details. I would like to note one interesting example: a computer with non-working RAM (which burned down or was simply installed in the wrong slot) does not even start. Laptops are based on the same principles of work, so we advise you to remember whether there have been any recent actions of a similar nature. We are talking about the assembly and disassembly of the device. Battery for a laptop at the same time may be generally aloof from the problem.

If the battery is connected and the laptop is not charging

What to do in such a case, when the system has successfully booted, but the user does not observe the charging process? In this situation, you can try to use the help of third-party, specially designed for such cases, programs and system utilities. They are, in fact, designed to scan the status of a laptop and its battery. By running the utility, you will begin the process of analyzing the energy store. He may give an answer to the question of why the laptop is not charging, and help solve this problem.

You can spend one kind of experience. To do this, we check the operation of the laptop, not only when it is connected to the electrical home network, but also offline. The following outcome is quite possible: in the first case, everything works stably, and in the second case, the device does not start at all. Then, with high probability, we can say that the problem lies either in the battery, which was inserted incorrectly, or in the damaged contacts of the board. Immediately, we do not recommend to climb inside, because an attempt to independently process the power contacts can lead to a complete breakdown of the laptop.

However, if you are confident in your knowledge and power, and are ready to allocate a considerable amount of money to restore or purchase a new device in the event of a breakdown, you can try to check the contacts and clear them. Of course, cleaning should be done only if it is really necessary, if the laptop is not charging for this reason.

Among the other reasons, because of which the battery does not charge, we can distinguish the failure of the power board. In this case, the power to the laptop comes. But it remains inside, not reaching the battery itself. Therefore, the actual charge itself does not occur.

What should I do if the laptop does not fully charge?

First you should remember when you encountered this problem for the first time. If such a feature of the laptop was from the very purchase, then, most likely, this is an option activated by the manufacturers of the model. This is done to extend the life of the factory battery. With this process (when the battery is not fully charged), it will last much longer.

There are situations when before the battery was fully charged, and at some point it stopped doing it. If such problems occur, you can try to "shake" the battery. What should be done? To start, simply discharge the device completely. After that, you need to connect the charger and charge the battery for 9 hours. This method does not give a 100% guarantee for the return of a full battery charge. If after such an operation you notice that it did not help you, then you can again use third-party utilities and programs. It is quite possible that something went wrong in the settings of the laptop and a new maximum charging threshold was set, different from 100 percent.

If the problem is not in the battery

Of course, laptop batteries have their own life, as well as all spare parts for such devices. But, faced with a problem in which the battery is not fully charged, it is not necessary first of all to write off everything on it. You should not think that the battery has come to an end. First of all, in a situation where the laptop does not start at all, you should check the reliability of its connection to the electrical network. That is, check the presence of current, as well as how correctly the charger is connected from two sides: both to the power supply and to the laptop itself. Perhaps the wire is simply not fully connected to the socket, and this was the cause of the problem. The situation worsens if everything listed above is done correctly, and the laptop still does not turn on or is not charging.

In this case, the next step should be to check the power supply. If it burned, then this will be an excellent explanation for the incorrect operation of the device. It is possible that the voltage drop in the electrical network or technical deterioration of this part and caused its breakage.

Conclusion

Help in fixing the problem in such cases can service centers. You can contact their specialists, they will also scan the entire laptop, if you did not manage to find out which of the components failed.

The main advantage of laptops over stationary PCs is their high mobility and the possibility of autonomous operation. Capable and efficient current sources allow to provide it, the parameters of which determine the duration of the laptop.

The laptop battery also contains special controllers. Very often, you can encounter a situation where, on a completely serviceable device, it suddenly starts behaving strangely - its charge drops off rapidly even with fairly economical use or the battery on the laptop does not fully charge.

Most of these situations can be associated with incorrect charging process or failure of the components of the electric circuit of the laptop.

Maybe the problem is not in the battery

Difficulties with power supply do not always lie in the autonomous current source. You can determine this at the stage of inclusion. In that case, if the device suddenly ceased to show signs of life when turned on, it is necessary to pay attention to the integrity of the electric circuit of the portable charging, as well as to the outlet to which it is connected.

For a start, it is worthwhile to study the situation, adhering to a simple algorithm:

1. check the performance of the outlet;
2. check the cords and connectors are properly connected;
3. determine the absence of problems with the power supply and cable;
4. check the charge in the battery itself, if it is removable and can be replaced. To do this, you can use a tester or a light bulb from a flashlight with suitable characteristics.

It often happens that a disconnected wire or a network cable that is not fully inserted into the connector leads to a rapid discharge. Particular attention should be paid to the integrity of the cable itself, since its regular use can lead to deformation of the wires near the connectors and the subsequent breaking of the contacts.

If the issue has not been resolved, then it is obvious to assume that there are certain problems in the power supply. You can check the electrical circuit yourself, using a special tester.

To check the health of the charger, you can use the same from another laptop. If, when it is connected, the laptop also does not show signs of life, it means a breakdown in it or in an autonomous power supply.

Typical battery problems

As you know, over time, the characteristics of chemical current sources fall, and this process is irreversible. One of the important parameters is the number of recharge cycles, in modern laptops it is about 700 times. This means that if a portable PC is connected to the power grid every day, then it will function properly for at least about two years.

If the portable PC was used for a long time, then it is likely that its batteries could gradually fail and can no longer provide sufficient charge.

Help determine if this can specialized software. Most manufacturers of equipment, in particular laptops and laptops, produce special utilities for testing the state of current sources.

As a rule, they give detailed information, among which are the following parameters:

• working capacity;
• voltage;
• temperature;
• charge level and others.

In addition to changing the characteristics of chemical elements, the problem may also lie in the failure of the controller. Usually it is located on a special board inside the battery pack or less often is built into the motherboard of the laptop itself. Check it will help specialized software utilities from the manufacturer or third-party developers.

Connected but not charging

The most common problem with the autonomous operation of a laptop is that it is connected to the network, it functions properly, but the charge does not occur. This indicates that the electrical circuit of the laptop and the charger is working, at least in terms of supplying electricity to the PC itself, but there is a problem with the controller. The reasons why the battery is connected, but not charging, can be several.

In the battery pack of the laptop is usually a few elements - from 3 to 12 pieces. If one of them turned out to be defective or prematurely failed, then the entire electrical circuit is likely to be broken and it needs to be replaced. With a sufficient level of knowledge, this procedure can be done independently, having correctly selected the necessary elements by parameters.

Do not neglect the need to regularly check the physical condition of contacts. Over time, they could oxidize or clog, causing poor contact of surfaces and malfunctions.

Photo: battery contacts

In this case, it is necessary to wipe all contacts with a office eraser. This procedure should be done carefully, in order to avoid damage to the contacts themselves and the elements located in the neighborhood.

Charging, but not completely

A situation where the battery is not fully charged may indicate such problems:

• physical wear of chemical elements;
• controller failure;
• actions of third-party utilities and managers.

In the first case, you can use the above-mentioned software methods for determining and diagnosing all important parameters. From the results obtained, you can determine their condition and the need for replacement.

Incorrect controller operation can also be determined using special programs or by standard methods of some operating systems.

In the latter case, the problem may lie in the fact that in the background running special utilities that control the power supply of the laptop and the charging process.

As practice shows, sometimes manufacturers of equipment or third-party developers offer software designed to adjust the parameters of the power source of a mobile PC. Such utilities automatically change the charging process, as well as optimize consumption and use of hardware power.

By disabling third-party utilities for managing PC resources, you can ensure that the battery status is displayed correctly and its charging is up to 100 percent.

If this does not happen, you need to do the following steps:

1. turn off the power;
2. disconnect the charger and remove the battery, if available;
3. hold down the power button for up to 30 seconds;
4. insert the battery without connecting the charger;
5. turn on the PC and check the power supply indicators.

Similarly, you can repeat this set of steps, but turn on a PC without offline batteries with a network connection. As a result of these actions, the residual voltage of all the capacitors on the board, without exception, will disappear.

It is recommended that the installed software or the built-in power manager be switched to the optimal power supply mode. The use of economy or maximum performance should be disabled.

Laptop battery does not charge

If the test results of the circuit revealed that the difficulties lie in the most autonomous current source, then there may be several solutions to this problem.

The main ones are:

Separate chemical sources of current in the unit can break the electrical circuit, making charging itself impossible. They can be replaced on their own or in a service center.

Failure of the controller may be caused by its failure or incorrect operation. In the first case, you will need to replace or repair the entire battery.

Third-party utilities will help diagnose problems, the most popular of which are:

In the latter case, it is necessary, as mentioned above, to inspect the contacts and, if necessary, clean them from debris or oxide.

After these actions, you can try to change the power supply mode with the standard means of the operating system and restart the computer.

Power controller

Charging modern lithium-ion cells requires a special power mode, which is actually provided by a special control board. If the battery has changed during operation, especially from third-party manufacturers, and then there are problems with its use - problems may be at the level of this component.

The most common ones are:

• laptop incompatibility. Even suitable batteries from other manufacturers may have some electronic components that differ in characteristics and parameters;
• a number of suppliers of equipment especially carefully approach the elimination of the use of fakes and embed protection against them even at the level of autonomous sources of electricity. Counterfeit components will simply not function on such a computer;
• entangled polarity on the board due to defective or counterfeit products. It is recommended to be extremely careful with the use of components from obscure suppliers, as the quality of their manufacture may be desired.

It is possible to find out why a failure has occurred, and also to check its serviceability using the same testing utilities or individual programs that analyze its indicators more deeply.

Indications in Aida64

The possibilities of the universal diagnostic utility Aida64 are truly wide. In addition to detailed information about all devices and components of the system, it also provides detailed information about the battery and its mode of use.

Particularly relevant will be checking before purchasing a portable computer that was in use. Diagnostics using this program, among other things, will show the number of recharge cycles of an autonomous current source, and the degree of its deterioration. According to these parameters it will be possible to draw conclusions about the approximate time of his work.

Among other things, Aida64 in the implementation of a comprehensive test of the laptop displays the following parameters of its autonomous current sources:

• manufacturer;
• date of manufacture;
• type of chemical elements;
• current capacity;
• current frequency;
• estimated time of work;
• temperature;
• voltage;
• power supply mode;
• the number of recharge cycles;
• deterioration and other parameters.

As can be seen from the above material, the laptop battery is a rather complex and highly risk-prone component. To use it properly, you should carefully use third-party portable charging and regularly test using specialized software.

Most of the problems that arise can be successfully resolved on their own and even without the need for major repairs. If the problem is not resolvable - contact the service center or warranty workshop.
