Users of portable PCs, namely laptops or netbooks, often encounter one common problem: when the laptop is turned on, the battery does not charge. In this case, the LEDs work, the device does not display messages about critical errors and. The only difference is that there is a message in the tray about the battery: “connected, not charging.” We'll look at how to charge the battery on your laptop in this manual.

A common glitch: the battery on the laptop stopped charging

Those who often deal with computer equipment have long been aware that “glitches” and buggies can occur for no apparent reason. This is true both for the OS (and not only Windows) and the hardware. The good news is that the vast majority of such “breakdowns” can be fixed with a simple reboot of the device. If the laptop writes: “the battery is connected but is not charging,” it would be a good idea to disconnect the battery and insert it back. To do this, just turn the device over bottom up and open one or two latches holding the battery. Remove the battery until its connectors stop touching the laptop connectors, then insert it back. The next time you turn on the device, it should work normally.

Why the laptop does not charge the battery: method two

If this happens and the charger is connected, the owner can help out by resetting the BIOS settings. This is explained by the fact that after a failure the device may not correctly detect the battery. This often happens if the user leaves a laptop or netbook connected without a battery, and also replaces the “original” battery with a new one. To reset BIOS settings, you will need:

• - Turn off the device.
• - Remove the battery (see above).
• - Disconnect the charger from the network.
• - Press the device power button and hold it for 60 seconds.
• - to a socket without a battery.
• - Press the power button and go into the BIOS.

If the battery on your Acer laptop does not charge, just press the F1, F2 or Del button. If the battery on your asus laptop does not charge, you should press F2 or Del to launch the BIOS. When the battery is connected but not charging on a Lenovo laptop, the BIOS menu is called up by pressing the same keys or F12. And if HP - just press the same buttons or Esc. In other brands of laptops or netbooks, the BIOS menu is called up by pressing the same buttons during boot. Carefully read the inscriptions in the start menu: usually at the bottom of the screen there is a hint which key combination should be pressed.

• - Find the Load Defaults item (most often it is located in the EXIT menu). This will allow you to apply the default hardware settings, that is, optimal for this device
• - When the BIOS prompts you to save the settings, click Yes, then turn off the device. To do this, just hold the power button for 10 seconds.
• - Disconnect the charger, then insert the battery and turn on the device.

Usually, after performing such a simple algorithm, Windows reports that the battery has been detected and is charging correctly.

The battery on the laptop is not fully charged: what to do?

Manufacturers often push on installation disk various useful utilities that serve to increase the performance of the device or its service life. These include energy managers. These programs serve to increase the life of the battery, almost always at the expense of an incomplete charge. This is the main reason why the laptop battery is not fully charged.

If the battery on your laptop is charging 60 percent or even less, you should look for and remove unnecessary software. Typically, such programs contain the brand of the laptop in the name. For example, if the battery on an Acer Aspire laptop does not charge, you should look for the Acer Power Management utility, and if the asus laptop has an incomplete charge, then, accordingly, Asus Power Management.

To find these utilities, launch Control Panel after clicking the Start button.

All software located in the "Programs and Features" section

Select the utility that does not allow you to fully charge your battery, and click the “Uninstall” button. Your device may need to be rebooted.

New battery: why is the laptop battery not charging?

If these methods did not help and you decide to buy a new battery, an unpleasant surprise may await you here too. If a new laptop battery is connected but is not charging, first make sure that the marking new part Fully corresponds to the old label. If everything is correct, in most cases the algorithms described above will help.

All these methods help in most cases when the laptop battery is dead and won't charge. When, after your “dancing with a tambourine”, the laptop still does not see the battery, intervention in the hardware will be required - perhaps the power controller has burned out. And it is better to entrust the procedure for replacing it to experienced specialists.

Laptop battery - 90% available (connected, not charging)

In this situation, it is not clear who is being disingenuous - the hardware or Win 7. New Fujitsu laptop... The battery is charged to 90% capacity, and then does not charge. When the power supply is connected, in the tooltip when I hover over the charge manager, I see the following message: “90% available (connected, not charging).” What kind of nonsense is this? Previously it was charging up to 100%. Please help with friendly advice. Thanks in advance.

This is a protection system on many laptops now, it charges only up to 90 so as not to spoil the battery with long useless loads, i.e. when the laptop is charged at 100%, the battery deteriorates.

Sanya | December 22, 2013, 20:58
Discharge the battery below 90% and charge it - it will go up to 100%.

Sergey Viktorovich | February 13, 2013, 11:42 pm
Perhaps your battery is set to “economy mode”, I can’t figure out what to call it correctly. I installed it on a Samsung laptop - there was the Easy Setting utility, where the default settings were set to 80%, but you could set your own value. It also only charged 80%. When I turned it off, it began to charge up to 100%.

Paul | 29 January 2013, 14:13
It often helps to remove and insert the battery. It is possible (and even advisable) to reboot the laptop. This method works especially often with new laptops.

Evgeniy | January 28, 2013, 10:19 pm
The battery may not charge to 100% for several reasons. Firstly, if a load is connected to the battery that constantly consumes current. Secondly, if there is an abnormally high self-discharge current. There could also be anything here, for example, some irreversible processes in the battery itself (to put it simply, you need to change the battery). Thirdly, the cause may be an unintended high leakage current caused, for example, by some kind of dirt. In this case, you need to wipe with alcohol.

The main advantage of laptops over desktop PCs is their high mobility and ability to operate autonomously. It can be provided by capacious and efficient current sources, the parameters of which determine the duration of the laptop’s operation.

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

Most of these situations may be associated with an incorrect charging process or failure of the components of the laptop's electrical circuit.

Maybe the problem is not the battery

Difficulties that arise with power supply are not always hidden in an autonomous current source. This can be determined at the switching stage. If the device suddenly stops showing signs of life when turned on, you need to pay attention to the integrity of the electrical circuit of the portable charger, as well as to the outlet to which it is connected.

To begin with, it’s worth studying the situation, adhering to a simple algorithm:

1. check the functionality of the outlet;
2. check the connection of the cords and the correct connection of the connectors;
3. determine that there are no problems with the power supply and cable;
4. check the presence of charge in the battery itself, if it is removable and replaceable. To do this, you can use a tester or a flashlight bulb with suitable characteristics.

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

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

To check the serviceability of the charger, you can use the same one from another laptop PC. If, when you connect it, the laptop also does not show signs of life, then there is a breakdown in itself or in the autonomous power supply.

Common Battery Problems

As is known, 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 laptop PC is connected to the power supply every day, it will function properly for at least two years.

If your laptop has been used for a long time, it is likely that its batteries may have gradually deteriorated and can no longer provide sufficient charge.

Specialized software can help determine whether this is so. Most manufacturers of equipment, in particular portable PCs and laptops, produce special utilities for testing the status of current sources.

As a rule, they provide detailed information, including the following parameters:

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

In addition to changing characteristics chemical elements, the problem may also be controller failures. It is usually located on a special board inside the battery pack or, less commonly, built into the motherboard of the laptop itself. Specialized software utilities from the manufacturer or third-party developers will help you check it.

Connected but not charging

The most common problem with the battery life of a laptop is that it is connected to the network, functioning properly, but is not charging. This indicates that the electrical circuit between 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. There may be several reasons why the battery is connected but not charging.

As a rule, a laptop battery pack contains several cells - from 3 to 12 pieces. If one of them turns out to be defective or fails prematurely, then it is likely that the entire electrical circuit has broken down and needs to be replaced. With a sufficient level of knowledge, you can do this procedure yourself by choosing the right necessary elements by parameters.

Do not neglect the need to regularly check the physical condition of contacts. Over time, they may have oxidized or become clogged, leading to poor surface contact and problems.

In this case, it is necessary to wipe all contacts with an office eraser. This procedure must be done carefully to avoid damage to the contacts themselves and elements located nearby.

Charging, but not fully

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

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

In the first case, you can use the software methods mentioned above to determine and diagnose all important parameters. Based on the results obtained, you can determine their condition and the need for replacement.

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

IN latest version the problem may be that special utilities are running in the background that manage the laptop’s power supply and charging process.

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

By disabling third-party utilities for managing PC resources, you can achieve the correct display of the battery status and charge it to 100 percent.

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

1. turn off the power;
2. disconnect the charger and remove the battery, if possible;
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.

In a similar way, you can repeat this set of steps, but turn on the PC without autonomous batteries and connected to the network. As a result of these actions, the residual voltage of all capacitors on the board without exception will disappear.

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

Laptop battery is not charging

If, based on the results of checking the circuit, it turns out that the difficulties lie in the autonomous current source itself, then there may be several options for solving this problem.

The main ones:

Failed individual chemical sources current in the unit can disrupt the electrical circuit, making charging itself impossible. They can be replaced independently or at a service center.

Controller failure may be caused by its breakdown or incorrect operation. In the first case, you will need to replace it 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 of debris or oxide.

Driver errors

The reason why the charging process does not occur may be due to the operating system power driver. You can fix this problem by reinstalling the driver or disabling it.

If the operating system you are using is Windows, then all the necessary settings are located in the corresponding section of the Control Panel.

To do this you need:

After these steps, you can try to change the power supply mode using the standard operating system tools 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 was changed during operation, especially from third-party manufacturers, and then problems arose with its use, the problems may be at the level of this component.

The most common of them are:

• incompatibility with laptop. Even suitable batteries from other manufacturers may have some electronic components that differ in characteristics and parameters;
• a number of equipment suppliers take a particularly careful approach to eliminating the use of counterfeits and build in protection against them even at the level autonomous sources electricity. Counterfeit components simply will not function on such a computer;
• reversed polarity on the board due to defective or counterfeit products. It is recommended to be extremely careful when using components from little-known suppliers, as their manufacturing quality may be poor.

You can find out why the failure occurred and also check its serviceability using the same testing utilities or separate programs that analyze its indicators in more depth.

Indications in Aida64

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

It will be especially important to conduct a check before purchasing a used laptop computer. Diagnostics using this program, among other things, will show the number of recharge cycles of an autonomous power source, and the degree of its wear. Based on these parameters, it will be possible to draw conclusions about the approximate operating time.

Among other things, Aida64, when performing a comprehensive check of a laptop, displays the following parameters of its autonomous current sources:

• manufacturer;
• date of manufacture;
• type of chemical elements;
• current capacity;
• current frequency;
• predicted operating time;
• temperature;
• voltage;
• power supply mode;
• number of recharge cycles;
• wear and other parameters.

As can be seen from the above material, a laptop battery is a rather complex component and highly susceptible to the risk of failure. To use it correctly, you should be careful about using third-party portable chargers and regularly conduct tests using specialized software.

Most problems that arise can be successfully fixed on your own and even without the need for major repairs. If the problem is unrecoverable, contacting a service center or warranty workshop will help.

The main task of a laptop and its main difference from a non-portable personal computer is mobility, that is, the ability to use it not only near an outlet, with the power always connected, but also in places remote from it. That's why every laptop has a removable battery, which can break down over time. If you encounter such a problem when the battery is not charging or is charging slowly, then you should not immediately take the device to technical service; first, you can try to fix the battery yourself. Below we will look at the main problems associated with the battery on a laptop with Windows 10.

Battery won't charge on Windows 10 laptop: how to fix the problem

There are several options for problems associated with a laptop battery, each of them has its own solution:

• The laptop sees the battery, that is, it is connected, but the charge level does not rise, but only decreases.
• The battery is not 100% infected, but only to a certain level.
• The power supply is broken, not the battery itself. That is, the problem lies not in the battery, it is in working condition, but in the wire itself, which cannot transfer charge to the battery for some reason.
• The computer does not see the connected battery.
• The battery I just purchased does not work with my laptop.
• The battery charges very slowly and discharges faster than it can charge.

Below in the article we will discuss solutions to all the problems described above, but before proceeding with them, follow these steps:

Checking battery wear

Maybe the battery has already outlived its useful life and it’s time to replace it. But to make sure of this, you need to use one of the free third-party programs for assessing the condition of batteries. One of the best and most convenient programs of this kind is Aida 64.

New battery doesn't work

If you bought a new battery for your old laptop, but it does not work, then there may be two reasons for this: the battery is defective, you should contact the place of purchase and ask for a replacement of the broken product with a new one or a refund, or the battery does not fit your computer model To make sure of this, compare the information on the batteries themselves in the form of a sticker.

Cleaning contacts

Check the physical condition of the external contacts on the battery itself and the laptop. There should be no plaque on them, all contacts should be smooth, not bent. If you find any debris on the contacts, carefully remove it with a dry cloth or rubber band.

The computer does not see the battery, the charge is distributed poorly

If the computer does not detect the connected battery, or it sees it, but the charge level is distributed incorrectly or fluctuates, then you need to perform the following steps, since the cause of the problem most likely lies in the fact that the system settings have been reset:

1. Unplug the cable from the outlet, and then unplug it from the laptop itself.
2. Remove the battery from the laptop slots. Typically, this is done by moving special latches in different directions.
3. Turn off your computer.
4. Reconnect the laptop to the power outlet, but do not insert the battery yet.
5. Start turning on the laptop and go to the BIOS by pressing the Del, F2 or F button. Which button to use depends on what brand your laptop is.
6. Select and activate the Restore Default function. It will reset all BIOS settings to standard, that is, if changes have been made to the main computer settings, they will be canceled, but your personal files and system settings will not be deleted or reset.
7. Save your changes by clicking the Save and Exit button and confirming the action.
8. Turn off the computer by holding the power off button for 6 to 8 seconds.
9. Unplug the laptop from the power outlet.
10. Return the battery to the computer.
11. Reconnect to power. Such frequent disconnection and connection to the network is necessary in order not to harm the batteries. Turn on the laptop and check the results of the work done.

Battery does not charge to 100%

If the battery does not charge completely, then there may be two reasons for this: the battery is broken or worn out, it is time to change it, or you have installed energy saving mode operation, which does not allow the battery to be fully charged in order to save the amount of energy spent and the battery life. To configure the battery mode, follow these steps:

What to do if the battery icon disappears

If in the panel quick access, which is located in the lower right corners of the screen, the battery icon has disappeared, then you need to follow these steps to get it back:

1. Using the Windows search bar, navigate to your PC settings settings.
2. Open the "Personalization" section.
3. Expand the “Taskbar” subsection.
4. In the “Notification Area” block, click on the “Turn system icons on and off” button.
5. Find the “Power” icon in the general list and activate its display.
6. You can close the settings. Next you need to go to Device Manager.
7. Expand the "Batteries" item.
8. Disable the "AC adapter (Microsoft)" section in it.
9. Restart your computer for all changes to take effect.

How to calibrate

Battery calibration involves first fully charging the battery and then discharging it to the very end. It is better to repeat this operation twice. This process will not improve or worsen the condition of your battery, but it will allow the system to more accurately determine the maximum battery capacity. This is necessary so that the computer can always accurately determine how many percent the battery is charged.

Useful widgets

To always be able to see how many percent of the charge is left before the computer turns off, you can use special widgets. They allow you to display on your desktop all the necessary statistics about the battery status. On the Internet you can find a lot of widgets with different designs and design, most of them are distributed free of charge. For example, you can use the CircleColor Battery program, which can be downloaded from the following link -

http://wingdt.com/circlecolor-battery.html. After installation, a circle will appear on the desktop that will change color depending on the charge level, and also display in large numbers information about the charge level in percent.

If none of the above methods helped you fix the problem with the battery, then there is only one thing left to do - take the laptop itself and its battery to a service center to get help from qualified specialists. You may have to buy a new battery, so write down in advance all the data about the old one that is on the sticker attached to it. You will need them to buy a battery suitable for your laptop.
