The battery on the laptop is connected but is not charging. The laptop battery is connected, but is not charging: reasons, what to do, solutions for brands lenovo (lenovo), hp, msi, asus (asus), acer, dell

Laptop connected but not charging is quite common among users of these mobile computers. The reasons may vary. 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 sign that a device has begun to fail, in some cases, is the incorrect and unstable operation of its battery. That is, you seem to have connected all the wires and the charger, there is current in the electrical network, but nothing happens. “Why won’t my laptop charge?” - such a question arises instantly under such circumstances.

In outline

It is worth noting that such a state for the battery of any device - be it a netbook, an ultrabook, or a laptop - is simply inevitable. A careful attitude and calculated load can extend the life of the battery, but you cannot make it last forever. Therefore, we are faced not so much with the task of prevention, but with the need to answer the question of why the laptop does not charge.

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

It all depends primarily on how often and intensively the device itself is used. That is, we are talking about autonomous battery operation. The more often you use your laptop without connecting to a power source (electrical network), the faster the drive will become unusable, which will lead you to solving this problem. Now let’s try to answer the question of why the battery on the laptop does not charge.

Checking the part

To move on to solving any problem, it is first recommended to establish the cause that caused it. The same is true in our case. Before you grab the tools and look for instructions on how to restore the battery, make sure that the problem is precisely its unstable operation. Only then look for the answer to the question of why the battery on the laptop does not charge.

So how can we determine the nature of such a peculiar breakdown, if it can be called that? To do this, turn on the laptop. If it starts, the device and operating system will function successfully, but when connected to a working electrical network, you will not see the charging process, then 99.9 percent is allocated to battery failure. In this case, you have a direct path to information sources that tell you why your laptop battery is not charging and how you can fix it.

If the device categorically does not want to start working, then the problem here is most likely not with the battery. Check if there is power in the electrical network. If there is, then perhaps the problem lies precisely in the power supply installed in the laptop, as well as in other parts. I would like to note one interesting example: a computer with non-working RAM (which burned out or was simply installed in the wrong slot) does not even start. Laptops are based on the same operating principles, so we advise you to remember if any actions of a similar nature have been performed recently. We are talking about assembling and disassembling the device. In this case, the laptop battery may not be a problem at all.

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 programs and system utilities specially designed for such cases. They are essentially designed to scan the state of the laptop and its battery. By launching the utility, you begin the process of analyzing the energy storage device. It may answer the question of why the laptop is not charging and help solve this problem.

You can conduct one unique experiment. To do this, we check the operation of the laptop not only when it is connected to the electrical home network, but also in offline mode. The following outcome is quite possible: in the first case, everything works stably, but in the second case, the device does not start at all. Then, with a high degree of probability, we can say that the problem lies either in the battery, which was inserted incorrectly, or in the damaged contacts of the board. We do not recommend going inside right away, since trying to process the power contacts yourself can lead to a complete breakdown of the laptop.

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

Other reasons why the battery does not charge include a breakdown of the power board. In this case, power is supplied to the laptop. But it remains inside, not reaching the battery itself. Therefore, in fact, no charge as such occurs.

What to do if the laptop does not charge completely?

First, you should remember when you first encountered this problem. If the laptop has had such a feature since its purchase, then most likely this is an option activated by the model’s manufacturers. This was 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 the battery used to be fully charged, but at some point it stopped doing so. If such problems occur, you can try to “boost” the battery. What should be done? To begin, simply discharge the device completely. After this, you need to connect the charger and charge the battery for 9 hours. This method does not provide a 100% guarantee that the battery will be fully charged. 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 laptop settings and a new maximum charging threshold was set, different from 100 percent.

If the problem is not the battery

Of course, laptop batteries have their own service life, like all spare parts for such devices. But, when faced with a problem in which the battery is not fully charged, you should not first blame everything on it. Don't think that the battery is dead. The first step in a situation where the laptop does not start at all is to 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 on both sides: both to the power source and to the laptop itself. Perhaps the wire is simply not fully connected to the socket, and this is what caused the problem. The situation gets worse if everything previously listed is done correctly, but the laptop still does not turn on or does not charge.

In this case, the next step should be to check the power supply. If it burns out, this will be an excellent explanation for the incorrect operation of the device. It is possible that a voltage drop in the electrical network or technical wear of this part caused its breakdown.

Conclusion

Service centers can help in identifying the problem in such cases. You can contact their specialists, they will also scan the entire laptop if you are unable to figure out which component has failed.

You’ve been using your laptop for several years now, you’ve never had any problems with charging – and then the surprises began. The first question that usually arises is: “Why is the laptop connected to the network, but the battery is not charging?”

There seems to be nothing terrible, the device works! But at the same time, it ceases to be a convenient mobile device, because to work you will always need to look for a free outlet. And in this case, how will it differ from a desktop computer?! Unfortunately, technology does not last forever and it tends to break down and fail at the most inopportune moment. As a result, we turn to service centers and specialists.

Let's start to figure out what could be the reasons why the laptop battery has stopped charging. There is no need to panic and immediately take it in for repairs or run for a new battery.

Resetting the battery settings

Sometimes battery charging problems can be caused by software problems with the laptop itself. To exclude this item, you must reset the battery settings in the BIOS in the following order.

1. Disconnect the device from the power supply: remove the plug from it and disconnect the power supply from the network.

2. We take out the battery: to do this, you need to move the two latches on the sides of the battery.

3. Press the power button and hold it for about a minute.

4. Connect the power supply to the laptop and the network; there is no need to insert the battery back.

5. Turn on the device and go into the BIOS: to do this, press the button or Delete, or F2, or F12.

6. Look for the item “SET DEFAULTS” or “Setup(Restore) Defaults” and save the settings by clicking “Save and Exit”.

7. Turn off the laptop: hold the power button for 5-7 seconds.

8. Disconnect the charger from it and insert the battery back.

9. Connect the charger and turn on the device again.

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

Faulty power supply

Another reason why the laptop battery does not charge may be a problem with the power supply.

To do this, turn off the device and disconnect the power from the outlet. Remove the battery. Insert the power plug into the laptop and the plug into the outlet. Now turn it on. If it does not work, then the reason is most likely in the power supply or its cord. It is also possible that the power supply plug has become loose and, as a result, the contacts are coming off. There is only one conclusion: you need to replace the power supply.

Removing "useful" programs

The power management program installed by the manufacturer may also interfere with normal battery charging. Look for the program in the tray. In this case, the battery icon will be slightly different from the usual system one. Such programs often implement a mode that ensures maximum battery life. Considering that modern operating systems are capable of independently determining the mode of its use and charging, it is better not to install such applications.

Needs to be replaced

Well, if none of the above works for you, then, of course, the most common problem is physical wear and tear of the battery.

The fact is that modern lithium-ion batteries can withstand approximately 800 recharge cycles. And with each charge they lose a little capacity. Therefore, in any case, in two or three years you will have to replace the battery on your laptop.

So we looked at the main reasons: why the battery on the laptop does not charge. Treat it with care and remember that sooner or later, you will still have to replace the battery.

Laptops are, first of all, fairly compact mobile devices. In other words, these are computers that you can carry with you. 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 is not charging. Fortunately, the problem does not always have to be fixed by replacing the battery - often the problem is due to 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.

Charger problem

First, we suggest you check the charger itself. Quite often, many people in a hurry forget that sometimes the problem may lie in the charger. You can check it literally in a matter of seconds if you have a second charger at home, a laptop with exactly the same connector and a working battery. But what to do if none of the above exists? Then we suggest you do the following:

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

Removing third-party software

Few people know that third-party software can cause this trouble. In principle, the same remark is also true for official software - an error can creep in anywhere, which will not allow the battery to be charged when the charger is connected. So, let's figure out how to remove the software:

As you can see, there is nothing complicated about this - a few simple steps and you will get a working battery again.

If this method did not work, and you are sure that the laptop battery is connected correctly, but is not charging, we have to disappoint you - the problem is unlikely to be related to the operating system and software. Most likely, you won’t be able to do without buying a new battery.

Laptop owners often encounter such a problem as the battery not charging when the power cord is connected to the network. This situation causes significant discomfort, and ultimately makes using the device simply impossible. What should you do if it’s connected and won’t charge?

What to do?

Before you do anything, you need to find out the cause of this problem. When it becomes clear what the matter is, it will be much easier to decide what to do.

Battery is connected but not charging: reasons

Any battery has its own service life, that is, a certain number of charges. It turns out that when the limit is exhausted, it means that the battery is worn out - this is one of the most popular reasons. In this case, you just need to replace the battery with a new one.

However, if your laptop is new, then you cannot refer to the “oldness” of the battery. In this state it should function normally. It is possible that there is a loose connection inside the battery, so you can try removing the battery and inserting it back.

The next reason is a malfunction in the circuit. If the battery is connected but is not charging, you should pay attention not to the battery or power supply, but to the motherboard. It has a microcircuit with a power distributor and electrical circuits. If it fails, the laptop will not charge.

The cause of the malfunction may also be a power failure. It may be banal, but it’s true. Therefore, you need to make sure that the network adapter and laptop cable are connected correctly.

Why is it important to deal with the problem right now?

If the battery is connected but not charging, working with such a device becomes difficult. After all, you have to always keep it connected to the mains. It turns out that the laptop loses its advantage - the ability to work autonomously. Therefore, you need to pay special attention to charging your device so that it is done correctly. Because in the end, more serious problems may arise that will require additional costs.

The battery protects the laptop hard drive and operating systems installed on it from sudden shutdown. It allows you to shut down Windows 10 correctly. There comes a time when you notice that your device is not charging. What do we have to do?

The essence of the problem with the battery on a laptop

Without a battery, the built-in drive would fail after several hundred or a couple thousand sudden power outages. It reacts very painfully to the interruption of recording/erasing data when the power supply is lost - poorly responsive and bad sectors appear on it, which is why programs currently running freeze in the most interesting place. And the Windows operating system would be reinstalled more often than once a month. It would be impossible to work on such a laptop.

When the battery is low, the default action for Windows should not be standby/hibernate, but shutdown.

This applies to all its versions - at least 98, at least 10. This way you will save the drive itself.

Why is it not charging?

There are several reasons for this.

Battery is connected but not charging

The following may be to blame.
Worn-out elements (batteries) - most often in laptops, elements of the standard size 18650 are used. But it takes up to 10 years for them to completely wear out (no longer hold a charge in the slightest degree). The controller installed in the battery itself also makes its own adjustments.
The original chipset drivers are not installed or damaged on drive C:. Go to your laptop manufacturer's website and download drivers specifically for your model from there. Reinstall them. If your laptop has a DVD-RW drive, most likely it comes with two disks - an original copy of Windows and a distribution kit with drivers. If you don’t have a disk drive, keep a flash drive or external HDD/SSD drive handy, which stores the “sources” for your laptop’s chipset.
A system failure, some devices not working, including the battery and power driver. Re-register these devices in the system. There is a separate step-by-step instruction for this.
The charger has failed (the power connection indicators on the laptop and the charger do not light up); the plug, socket, or charger output connector are damaged; the wire has frayed (the eternal problem of cords at bends at the point of their connection with the plug/connector); the contacts in the socket and in the connectors of the laptop or charger do not fit tightly; the contacts and/or connector of the battery itself or its socket on the laptop are loose or damaged. Check all of the above.

Re-registration of controllers and power circuits in a laptop

Here and below, Windows 10 is used as an example. In general, the latest versions of Windows, starting with Vista, already have the necessary drivers and system libraries that control the power of any portable PC (even tablets with Windows). They allow you to customize the behavior of the laptop entirely to your liking. Do the following.

If none of the above steps helped, try System Restore, check for updates, or reinstall Windows 10 again. These steps are the same for all versions of Windows, starting with XP Service Pack 3.

Loads up slowly

The reasons are as follows.

The controller is faulty (its microcircuits have failed after 10 or more years of continuous operation, this also happens). Look in repair shops and computer service centers for a similar controller that produces similar parameters (charge current, operating and input voltage range). But this solution is for experienced “techies” - it is better to completely replace the broken part.
You are using “charging” from another laptop (netbook), the power of which differs by 1.5 - 2 times, but matches the output voltage (for example, 19 volts). The laptop itself is capable of operating from an input voltage of 16 - 20 volts, this is provided by a built-in switching stabilizer inside the laptop (it produces 15 volts), located in the circuit before the battery controller. All circuits have protection against overvoltage, internal short circuits of power buses and wires, and temperature protection. It is possible that the charger is too low-power - when the laptop is running, recharging does not occur, and slow discharge is possible: this occurs in low-budget Chinese mini-laptops. Use the original charger or, if it is faulty, purchase another one with the same parameters.
As a result of independently replacing the elements (if the controller correctly recognized the new ones and works with them), you installed elements not with 10 watt-hours each, but larger ones, say, with 14. This is natural. Lithium-ion battery technology is improving; 18650-size “cans,” which 5 years ago contained 10 watt-hours of usable power, today can provide 11 to 18 watt-hours. Consider yourself lucky - you have given your “laptop” battery a second life, and its capacity has also increased significantly. It is recommended to use a “charging” that is somewhat higher in power, but do not overdo it - it is unlikely that the controller is designed for a higher charging current.

Poor charge distribution

The reasons are as follows.

Again, the controller is faulty - the battery circuit is such that each element (or group of elements) is controlled, and any of the corresponding sections of the controller could fail.
Manufacturing defects. Replace.
During self-disassembly, not all battery elements are replaced - the old ones are already worn out and cannot provide the required power, and because of this, the new ones are not used 100%, the charge is “conserved”, which negatively affects them.
The battery controller is not calibrated. Cyclic discharge-charge is required (several consecutive cycles).

The battery status icon has disappeared from the Windows taskbar

The reasons may be:

accidental change in settings of the Windows tray icon area;
“virus attack” (most often caused by visiting unverified sites), which damaged the system processes winlogon.exe, explorer.exe and others responsible for the current session of working with Windows, managing the desktop, Windows Explorer and the taskbar (including the notification area);
Damage to system libraries and drivers that are Windows components due to frequent installation of new programs (the reason is a conflict of shared system resources that could be replaced by newer versions).

To check your battery status display settings, do the following.

Right-click on the taskbar and select Settings.
Select this item
Click the "Customize" button on the taskbar tab.
In the Windows general settings window that opens, select the notifications and actions tab and click the link to select the icons displayed in the tray. A set of them will open.
Entering Windows tray icon settings
Check to see if the battery icon (Power) is showing.
The battery icon must be active

It happens that icon settings are not saved, control over the display of one or more icons freezes, this tool launches after one or two or does not respond at all, or there are errors in third-party Windows optimization utilities (for example, incorrect work with the Auslogics Boost Speed package, jv16PowerTools, CCleaner, etc.). In the most advanced cases, a Windows message is displayed with or without an error code (code 0) - a sign of damage to the system files of the Windows folder (regardless of the method of damage).

In this case, only reinstalling Windows 10 is guaranteed to help.

Battery calibration

Contrary to all the instructions that various authors are desperately promoting, there is the most painless way for a laptop to “bleed” the battery without doing anything special. Do the following.
Shut down Windows by giving the command “Start - Shut down - Restart”.
When Windows is finished and the logo of your laptop manufacturer appears on the screen, there will be an inscription in English below, for example: “To enter BIOS Setup, press (hold) Delete (F2, F4, F7).” The required key and behavior with it depends on the manufacturer's instructions. Perform the indicated action.

The BIOS settings will open. That's it, step away from the laptop. When the charge is depleted, it will turn off itself. The screen is lit, the laptop fans are running, and battery power is being consumed.

After the battery is drained and the laptop is turned off, connect the charger to the laptop and charge the battery. Whether this happens with the laptop turned off or running does not matter much: “charging” has a good power reserve. If necessary, repeat a full discharge with the BIOS menu running, followed by a final charge.

If the battery is not completely discharged (for example, there is still 40% left), but the laptop turns off and does not turn on, connect the charger, turn on and put the laptop into BIOS mode, then unplug the laptop. It will most likely keep running until it runs out of that 40% charge. Repeat the charge-discharge process again - the charge level record in the controller will be updated, and the battery will work as it should again.

In computer centers, auxiliary methods are used to train and calibrate batteries: analyzers and “smart” chargers, old disassembled laptops without a hard drive and display, etc. - the choice depends on the decision of a specialist.

Windows 10 Widgets and Panels for Status Tracking

There are several ways to monitor the battery status in Windows 10.

The already familiar battery icon is on the taskbar, next to the system calendar. Clicking on it opens a window displaying the charge level and links to power settings.

Laptop battery status in Windows 10: the first one is more discharged than the second

For normal operation in Windows, you may need to optimize energy consumption when running on battery power. For example, you need to configure your laptop to shut down Windows when the charge drops to 3%. Give the command “Start - Settings - System - Power and sleep mode.”

Power and sleep mode in Windows 10

If this is not enough for you, the link for additional power settings will allow you to switch between existing modes and create new ones (to your liking). You can also open the Windows 10 power planner by going to the Battery Saver submenu.

Set up power plans

Complete battery statistics can be saved to a separate file. Launch the Windows command line by pressing Ctrl+X on your keyboard and enter the command: “powercfg /batteryreport /output “C:\ battery_report.html”. As can be seen from the command format, the PowerCfg (power configurator) system process will start. Then open the created file using any browser (for example, Mozilla Firefox) - you will see statistics of the last hours (or days) of battery use, the completeness of its discharge-charge cycles (when the charger was turned on and off).

This information may be useful if you are experiencing battery problems.

You can also get to the power settings in Windows 10 by clicking on the page-shaped icon in the system tray and selecting the desired one from the list of widgets - “Battery Saver”. The familiar window for settings for Windows behavior when the battery is low will open.

Another way to get to the battery parameters

How to return the battery icon to the classic style

Diagnosing the condition of the battery on your own is not a difficult task. The right decision will minimize your costs - you will only pay the cost of a new battery or replacing faulty elements as soon as necessary.
