Why the laptop does not charge and what to do in such cases?


If you encounter problems with charging, many people ask themselves “why is the laptop connected but not charging?” And they are in a hurry to replace it with a new one. Yes, the battery is a consumable item. It is designed for a limited number of charge / discharge cycles, and over time, the capacity becomes much less than the nominal value indicated by the manufacturer. but absolutely optionally, the problem with charging will be solved by replacement. In this article, we will consider the three most common problems and tell you what to do to solve them.

Problem: Battery on laptop stopped charging

It happens that a device that used to charge normally - from one point it stopped doing it. The laptop works, the battery is connected correctly, but it does not charge. Confirmation of this is the absence of an inscription when hovering over the battery status icon in the tray. There are three ways to solve the problem.

Method 1 - reset the battery settings in the BIOS

  1. Turn off the power. Unplug the power supply plug from the device or unplug it from the power outlet.
  2. Take out the battery. In models with a removable battery, and most of them, for this it is enough to simply turn the device over and push one or two locking devices that hold it.
  3. Press the power button and keep it in this state for about a minute.
  4. Insert the plug of the power supply into the laptop and connect it to the mains. At the same time, the battery does not need to be replaced yet.
  5. Turn on the laptop and enter its bios. To do this, at startup, press a key or a combination of the keys specified in your user manual. Typical solutions: Del, F12 or F2.
  6. Reset the settings to the default value, Restore Defauts, and save the bios, Save and Exit settings.
  7. Turn off the laptop by holding the power button for 5-7 seconds.
  8. Again, turn off the power supply and install the battery in place.
  9. We insert the charging plug and turn on the power supply to the outlet.
  10. We turn on the laptop in the usual way.

If the method worked, then we should see the system message by hovering the mouse over the tray icon: the battery is connected and charging.

Method 2 - removal of “useful” utilities

In some models, manufacturers install “useful” utilities that monitor the state of charge. In particular, they sometimes implement a mode that provides the maximum battery life. It may prevent the battery from fully charging.

Try to search for such a program in the system tray. If the battery icon differs from the usual system one, then it is likely that some similar utility is installed on your laptop. Modern operating systems are quite capable of independently determining the optimal mode of using the battery and its charging. So it’s better not to install any third-party applications.

Method 3 - if the power supply does not work

Another reason may be the loss of operability of the power supply and a decrease in the reliability of its plug. In this case, the battery has nothing to do with it. It is verified simply.

  1. Turn off the laptop, unplug the power supply.
  2. Remove the battery, insert the plug of the power supply.
  3. Plug the power supply into a power outlet.
  4. Press the power button.

If after that the laptop did not work, then the power supply or its cord failed. Also, the old power supply may not provide enough current to run the laptop and charge its battery at the same time. Such a device must be replaced.

Step 1. Check the battery status.

You can check the battery status with the free Battery Health program for iOS or the standard Battery Care utility in devices running Windows 7 and 8.

The three main parameters of battery health are important to us.

  • Declared, rated, power. This is the capacity of the new battery when it just left the factory.
  • Maximum power. This is the current capacity value.
  • Battery wear as a percentage. The larger this value, the higher the need for replacement.

The problem of not reaching the required charge level is also solved by calibration.

Step 2. Replacing the battery (if necessary)

If the wear is high, then it is likely that this is the reason for the decrease in battery life. To solve the problem you will need a new battery, in most models it is removable. In this case, you can change it yourself. In a number of modern compact models, the battery is not removable and its independent replacement will be more difficult. It is safer to do this in the service center.

Step 3. Diagnostics of programs on a laptop

If in step 1 regarding the battery, the diagnostic utility showed no serious wear, the battery is probably not a direct cause of the decrease in battery life. The culprit of the fast discharge may be some recently installed program that runs in the background and does not allow the processor and the Wi-Fi chip to go into economy mode.

Open Task Manager by pressing Ctrl + Shift + Esc and analyze CPU usage by background programs. Sort the applications on the list by processor usage and observe for a while. Removing unnecessary programs running in the background will increase battery life.

What to do if a new battery is not charging

A much more complicated situation is when only the installed new battery on the laptop does not charge at all. To get started, we recommend that you perform the bios reset operation described above.

If the problem persists, then the first thing to do is check the labeling. It should not differ from the marking of the old battery. When buying a new one in the store, always take with you either the laptop itself or the old battery for reconciliation.

Do not run to change components ahead of time

Try the methods of restoring the functionality and diagnosing the cause of the malfunction described in our article. A battery, especially a new one, rarely fails suddenly. Where more often are software problems or failures in the operation of the power supply or its connectors. Check all the options, and only then decide on the purchase of a new device.

Causes and troubleshooting

In fact, there are not so few reasons, however, in order to sort them all out, we simply do not have enough time, and the article itself can turn out to be of such a size that it can be read at least all day. Therefore, we will analyze the most popular factors due to which a charging problem may occur.

  • System crash. The first one. what you have to do is remove the battery from the laptop, having not previously forgotten to disconnect all connected devices from it and turn off the power from the outlet. After taking out the battery, be sure to wipe the contacts on it - maybe they just oxidized (for example, someone without your knowledge uses a laptop in the bathroom). After that, install the battery in the proper place and plug the device into the network, and then press the Power button. Such a simple operation works in about half the cases, and if this does not help you, then you can switch to the next paragraph of this article.
  • Lack of voltage in the power supply network. This suggests that there is simply no voltage in the outlet. It may be that the problem is relevant for your entire apartment, or perhaps the problem is associated with one single outlet. Plug the adapter into another outlet.
  • Problems with the cord. In other words, it has mechanical damage, often invisible to the eye. For example, a wire broke under a braid. Such cases are rare, but still happen. Check the voltage with a tester, if you have one. If this is not possible, then you can check the power supply in two ways: by connecting it to another laptop, or by using a known working power supply that is suitable for your device. Most often, the user does not even have such an opportunity, so he can only buy a new adapter, which is not very cheap.
  • The adapter does not work. If there is no problem with the wire and you are 100% sure of this, then the adapter itself may break. At the same time, do not be surprised if its indicator lights up - this does not mean at all that the device is working or working correctly. The solution to this difficulty is described in the previous paragraph.
  • The battery driver ordered a long life. Not everyone knows that laptop batteries have their own drivers that are installed by the manufacturer. In most cases, the user will never know about them, but sometimes they show themselves in all their glory, namely, they are damaged. The solution is simple - you need to download the driver directly for your model, which can be found on the manufacturer’s website. If this was not possible, then you can download universal programs that can identify faulty and damaged drivers and replace them with obviously working ones. Here are just such cases that occur extremely rarely.
  • The power controller does not work. In this case, the problem is interesting in that the battery can be charged with it, but not in all cases. Here is an example. You have connected your laptop to the network, but there are no signs of charging. You take out the adapter plug, reinsert it and - oh, miracle - charging has begun. This most often indicates that the power controller is out of order and must be replaced at a service center. But this applies only to those cases where repair can cost you a small amount, in the rest it is better to purchase a new battery, because such a procedure can draw a lot of money out of you. What to do, it's up to you.
  • The battery has run out. What does this mean? And the fact that the battery life is running out. In other words, it will not work to charge it; in fact, it "died". You can restore the battery and some SCs are quite successfully doing this, however, you are unlikely to wait for the guarantee that after a few days or weeks the battery will not fail. However, it depends on the service you plan to contact.
  • Battery performance has deteriorated significantly. In this case, unlike the previous one, the laptop is charged without any difficulties, however, the main problem is that the charge lasts for several minutes instead of several hours. You can try to solve this problem yourself. Fortunately, the method is very simple, although it will take a lot of time. You need to put the laptop into sleep mode. Now we wait until the battery is completely discharged and do not touch the laptop for a few more hours. Then we charge the battery using the power supply. This procedure must be repeated three times. According to users who have tested this method on their devices, it works almost flawlessly.
  • High battery consumption. This suggests that excess power consumption appeared in the laptop, which is most often associated with moisture, malfunction of microcircuits, or mechanical stress. The final reason can be found after diagnosing the battery.
  • Problem in BIOS. Such a phenomenon, although rare, but still happens. It is connected with the fact that a software failure occurs in the BIOS (for example, you incorrectly updated the system). In theory, the problem can be solved if you at least know how to use Google. In other cases, we recommend that you do not tempt fate and entrust your laptop into the hands of masters working in service centers.

Is the battery worth repairing?

If you find out that the problem lies in the battery, the SC will probably offer you to restore or repair it. Is it worth it? Yes, but not in all cases. Why?

The fact is that the process itself is very laborious, and therefore requires special skills. Accordingly, the entire procedure should be carried out by specialists. In this case, the workshop must first be sure that the battery will really work after recovery. If experts are not sure about this for sure, then most likely they will refuse you and do the right thing. Here are just a lot of companies assure their client of the rationality of such a procedure, trying to grab money from him, and at the output the battery lasts at best for several days, after which it simply “dies”. In addition, the cost of work is often not much lower than buying a new battery.

By the way, about buying a battery. Today on the market you can see many different devices made by Chinese businessmen. Do not laugh, many of them have proven themselves well, and their cost compared to the original is sometimes two times, or even three. But before the purchase, it will not be superfluous to read reviews about the manufacturer on the Internet. Noname purchase is not recommended, you can fall for a frank fake. We will discuss this issue in more detail in one of our next articles.

The battery is connected, it does not charge (or it does not charge in Windows 10)

Perhaps the most common variant of the problem is that in the status in the Windows notification area you see a message about the battery charge, and in brackets - “connected, does not charge”. In Windows 10, the message is “Charging not in progress.” This usually indicates software problems with the laptop, but not always.

Battery overheating

The above “not always” refers to overheating of the battery (or a faulty sensor on it) - when overheated, the system stops charging, as this can damage the laptop battery.

If the laptop that was just turned on from the off state or hibernation (to which the charger was not connected during this) is charging normally, and after some time you see a message that the battery is not charging, the cause may be the battery overheating.

The battery does not charge on the new laptop (suitable as the first method for other scenarios)

If you purchased a new laptop with a pre-installed licensed system and immediately found that it is not charging, this can be a marriage (although it is not likely), or incorrect initialization of the battery. Try the following:

  1. Turn off the laptop.
  2. Disconnect "charging" from the laptop.
  3. If the battery is removable, unplug it.
  4. Press and hold the power button on the laptop for 15-20 seconds.
  5. If the battery was removed, replace it.
  6. Connect the laptop power supply.
  7. Turn on the laptop.

The described actions do not help often, but they are safe, they are easy to perform, and if the problem is solved immediately, a lot of time will be saved.

Note: there are two more variations of the same method.

  1. Only in the case of a removable battery - turn off charging, remove the battery, hold down the power button for 60 seconds. First connect the battery, then the charger and do not turn on the laptop for 15 minutes. Include after that.
  2. The laptop is turned on, charging is turned off, the battery is not removed, the power button is pressed and held until it is completely turned off with a click (sometimes it may be absent) + about 60 seconds more, charging is connected, wait 15 minutes, turn on the laptop.

Reset and Update BIOS (UEFI)

Very often, certain problems with power management of the laptop, including charging it, are present in early versions of BIOS from the manufacturer, but as users experience these problems, they are fixed in BIOS updates.

Before performing the update, just try resetting the BIOS to the factory settings, usually the items “Load Defaults” (load default settings) or “Load Optimized Bios Defaults” (load optimized default settings) are used on the first page of BIOS settings (see How to enter BIOS or UEFI in Windows 10, How to reset BIOS).

The next step is to find downloads on the official website of the manufacturer of your laptop, in the "Support" section, download and install an updated version of BIOS, if available, specifically for your laptop model. Important: carefully read the official BIOS update instructions from the manufacturer (they are usually found in the downloadable update file as a text or other document file).

ACPI and chipset drivers

In terms of problems with battery drivers, power management, and the chipset, several options are possible.

The first method may work if the charging worked yesterday, but today, without installing the “big updates” of Windows 10 or reinstalling Windows of any version, the laptop stopped charging:

  1. Go to the device manager (in Windows 10 and 8, this can be done through the right-click menu on the "Start" button, in Windows 7, you can press Win + R and enter devmgmt.msc).
  2. In the “Batteries” section, find “Microsoft ACPI-compatible Management Battery” (or a similar device in name). If the battery is not in the device manager, this may indicate a malfunction or lack of contact.
  3. Right-click on it and select "Delete".
  4. Confirm removal.
  5. Reboot the laptop (use the “Reboot” item rather than “Shutdown” and then turn it on).

В тех случаях, когда проблема с зарядкой появилась после переустановки Windows или обновлений системы, причиной могут стать отсутствующие оригинальные драйверы чипсета и управления электропитанием от производителя ноутбука. Причем в диспетчере устройств это может выглядеть так, как если бы все драйверы были установлены, а обновления для них отсутствуют.

В данной ситуации зайдите на официальный сайт производителя вашего ноутбука, загрузите и установите драйверы для вашей модели. Это могут быть драйверы Intel Management Engine Interface, ATKACPI (для Asus), отдельные драйверы ACPI, и другие системные драйверы, а также ПО (Power Manager или Energy Management для Lenovo и HP).

Battery connected, charging (but not really charging)

“Modification” of the problem described above, but in this case, in the status in the Windows notification area, it is displayed that the battery is charging, but in fact this does not happen. In this case, you should try all the methods that were described above, and if they do not help, then the problem may be:

  1. Faulty laptop power supply (“charging”) or lack of power (due to component wear). By the way, if there is an indicator on the power supply, pay attention to whether it is on (if not, there is clearly something wrong with the charge). If the laptop does not turn on without a battery, then the matter is probably also in the power supply (but maybe in the electronic components of the laptop or connectors).
  2. A malfunction of the battery or controller on it.
  3. Problems with the connector on the laptop or the connector on the charger are oxidized or damaged contacts and the like.
  4. Problems with the contacts on the battery or their corresponding contacts on the laptop (oxidation and the like).

The first and second points may cause problems with charging even if no messages about the charge appear at all in the Windows notification area (that is, the laptop is running on battery power and “does not see” the power supply being connected to it) .

Laptop does not respond to charging connection

As noted in the previous section, the lack of response of the laptop to connecting the power supply (both when the laptop is turned on and off) can be a result of problems with the power supply or the contact between it and the laptop. In more complex cases, problems may be at the power level of the laptop itself. If you cannot diagnose the problem yourself, it makes sense to contact a repair shop.

Additional Information

A couple more nuances that may be useful in the context of charging a laptop battery:

  • In Windows 10, the message “Charging is not performed” may appear if you disconnect the laptop from the network with a charged battery and, after a short time, when the battery has not had time to be seriously discharged, reconnect (in this case, the message disappears after a short time).
  • Some laptops may have the option (Battery Life Cycle Extension and the like) to limit the percentage of charge in BIOS (see Advanced tab) and in proprietary utilities. If the laptop starts to report that the battery does not charge after reaching a certain charge level, then this is most likely your case (the solution is to find and disable the option).

In conclusion, I can say that in this topic the comments of laptop owners with a description of their solutions in this situation would be especially useful - they could help other readers. At the same time, if possible, tell the brand of your laptop, this can be important. For example, for Dell laptops, the method with updating the BIOS is more likely to work, on HP it turns off and on again, as in the first method, for ASUS it installs the official drivers.
