What to do if the battery is not detected on the laptop and the reasons for this message. The laptop does not see the battery The computer does not see the battery

Many users often use their laptops without a network connection, running solely on battery power. However, sometimes the hardware malfunctions and is no longer detected by the laptop. There may be several reasons for the malfunction, when the laptop does not see the battery and the question arises: “What to do,” and it is caused not only by problems with the battery, but also by interruptions in the software part of the laptop. Let's take a closer look at the options for solving the battery detection error on a laptop PC.

When the problem in question occurs, the system tray icon notifies the user of this with an appropriate warning. If after executing all instructions the status changes to "Connected", which means that all actions were performed correctly and the problem was successfully resolved.

Method 1: Hardware update

First of all, it is worth restoring the equipment, since the problem that arose could have been caused by a minor hardware failure. The user is required to perform only a few simple steps. Follow the following instructions and the update will be completed successfully:

Resetting the hardware helps most users, but this only works in cases where the problem was caused by a simple system failure. If the steps taken did not bring any results, proceed to the following methods.

Method 2: Reset BIOS Settings

Certain BIOS settings sometimes cause certain device components to not work correctly. Configuration changes may also cause problems with battery detection. First of all, you will need to perform a factory reset to return the settings to factory defaults. This process is carried out using different methods, but they are all simple and do not require additional knowledge or skills from the user. You will find detailed instructions on how to reset BIOS settings in our article at the link below.

Method 3: Update BIOS

If resetting the settings did not produce any results, you should try installing the latest firmware version for the BIOS of the device you are using. This is done using third-party utilities, in the operating system itself or in the MS-DOS environment. This process will take a little longer and will require some effort, carefully following each step of the instructions. Our article describes the entire process of updating the BIOS. You can view it using the link below.

In addition, if problems arise with the battery, we recommend testing it using special programs. Often malfunctions are observed in batteries whose life is already coming to an end, so it is worth paying attention to its condition. Below is a link to our article, which describes in detail all the methods for diagnosing a battery.

Today we have discussed three methods that can be used to solve the problem of detecting a battery in a laptop. They all require certain actions and vary in complexity. If none of the instructions bring results, you should contact a service center, where professionals will diagnose the installed equipment and carry out repair work, if possible.

The key element in a laptop is the battery, without which its mobility is impossible. Therefore, any problems in this aspect worry users first of all. Against the background of existing problems associated with battery operation, it is worth considering in detail the most common one - why the laptop does not see the battery. Knowing the reasons, you can correct the situation yourself without resorting to the help of specialists.

Description of the problem

There are often cases when, even if the battery is working properly and installed correctly, the laptop does not see it. In such a case, there is a red cross on the corresponding icon located in the taskbar. When you hover the mouse cursor over it, a message appears - “Battery not detected.”

Additional factors indicating a battery malfunction:

• The battery does not retain the incoming charge.
• The charging indicator light is blinking or is off.
• The battery is not detected by the computer.
• The charge is constantly kept at the same level.

The length of time a laptop can operate without receiving a charge depends on the capacity of the battery and the degree of its wear. If you do not solve the problem, you will need to connect the gadget to an electrical outlet.

A similar situation is possible if you constantly keep the device connected to the mains.. Over time, the operating time of your computer on a single charge will decrease. This is due to the negative impact of direct currents on the battery. As a result, the laptop completely loses its visibility.

Main causes and methods of detection

Why does the laptop not see the battery:

• technical problems with the battery;
• incorrect connection;
• OS crash;
• problems with the motherboard.

The first thing they do is replace the battery with a working one. If it is detected, then it's all about the battery. Otherwise, they look for a fault in the motherboard.

Since not everyone has a spare battery, there are other checking options.

Checking adapter functionality

For stable charging, the power adapter must be fully functional. This is checked in the following way:

1. Reboot the computer.
2. In the first seconds of startup, press the F2 key and wait until a message appears about going to the settings - Entering Setup.

In the BIOS modification, the power adapter type is set correctly. If the word “no” appears opposite, then make sure that the device is connected to the PC. When the adapter is assigned the “Unknown” status, perform a series of sequential actions proposed by the system to correct the problem. If it is correctly detected, they move further in search of the root cause.

Running a diagnostic test

Launching the diagnostic program allows you to determine the cause of the malfunction and solve the problem according to the proposed scenario. There are built-in (Imtec Battery Mark) and online tests. To activate the first option you will need:

1. Turn on the laptop and press F12.
2. In the menu that appears, select “Diagnostics”.

If the check results are negative, go to the “ePSA, PSA Error Codes and Troubleshooting Steps” section. Further manipulations are coordinated according to the instructions issued there. If the diagnostics are successfully completed, they conclude that the primary source of the problem is the operating system.

To check online, you need to download a utility that corresponds to a specific brand of computer. So, on HP it is Support Assistant, on Dell - Support Assist.

Solving the problem

To get the battery working on your own, it is recommended to try several methods:

• reset the hardware settings by resetting the BIOS;
• charge the battery without connecting a computer;
• restore or reinstall the system;
• run a troubleshooting program;
• reinstall the battery driver.

Reset BIOS

BIOS is software built into the computer's motherboard. By resetting it to the initial version programmed by the manufacturer, it is sometimes possible to restore full interaction between the device and the battery. A similar situation arises when the factory settings were changed or a new battery was installed.

This can be done directly through the BIOS, provided that the computer is powered by a power adapter.

Adhere to the following algorithm:

1. Turn off the device and remove the battery.
2. Remove the charger from the network.
3. Press the Power button and hold for at least 30 seconds.
4. Connect the laptop to the outlet without installing the battery and start it up.
5. Go to BIOS.

Entering the BIOS system is carried out by pressing the corresponding button at the time of startup, which varies by device model - mainly F1, F2, F12, Del or Esc. At the bottom of the menu there are tips that you should pay attention to.

Select Load Defaults or Standard CMOS Features and agree to save the settings when prompted.

The final step is to turn off the PC, unplug it from the outlet, insert the battery and turn it on again. Often such simple manipulations lead to positive results.

Charging the battery with the PC turned off

The performance of the battery can be negatively affected by several factors: incorrect driver functionality, failures in power management. Recharging the battery separately, separately from the OS, eliminates the hardware from being a problem. To do this, turn off the PC and recharge the battery in this state.

After resuming work, they check whether the charge level has increased or not. If nothing has changed, move on to the next step.

Restoring and/or reinstalling the OS

Another cause of trouble may be Windows system failures. If the possibility of a battery failure is excluded, then there are two options: restoring or reinstalling the OS.

The first option involves returning to the time period when it was detected by the computer. Just go to the menu, where a list of available recovery points will be displayed in a pop-up window. They choose the appropriate one, focusing on the date, and activate the process. Then the program will do everything itself without outside intervention.

The second option is considered more radical, but effective. Before you start reinstalling the OS, it is recommended to save important files on a flash drive or move them to the cloud. Then completely reboot the system using a separate boot disk.

Running Microsoft Fix-It as a troubleshooter

A special tool built into the Windows OS for troubleshooting problems of this kind will help solve the problem with the battery. Available only for versions 7, 8/8. 1 and 10.

Step by step instructions:

1. Press the Windows + R key combination on the keyboard.
2. In the dialog box that appears, type the Control command and launch it using Enter.
3. In the search bar located in the control panel, enter Trouble shooter and click on “Troubleshooting”.
4. In the “System and Security” tab, activate the “Power” icon.

You will then need an administrator account to log into Windows. If the User Account Control prompt appears during startup, you must accept it.

Removing and installing the Microsoft ACPI battery driver

Reinstalling the device driver is another step that can give the desired result and correct a difficult situation. Sequence of actions:

1. Press two keys at the same time: Windows and R.
2. In the dialog space called "Run", type - devmgmt.msc and press enter.
3. In the “Device Manager” section, put a plus or a check mark next to the “Batteries” column.
4. Right-click to select “ACPI-Compatible Battery Management (Microsoft)” and left-click to select “Delete”.
5. Confirm the completed manipulations via Ok.

All that remains is to restart the computer and check that the battery is functioning properly.

Other types of problems

If none of the proposed actions are effective, it is worth considering several more options for correcting the malfunction.

Brief overview:

• Accumulation of remaining charge - suitable for laptops with a removable battery and involves clearing temporary memory of unnecessary information. Why do they completely disconnect the PC, including from the network. Remove the battery from the socket, then press the power button and hold for 20–30 seconds. Insert the battery into place and start the computer.
• Replace the battery with a new one - if the icon in the taskbar is crossed out from the inside with a red cross. This designation indicates high wear and tear of the equipment. The same is done when the battery quickly loses its charge and often needs to be recharged.
• They change the wire - when it is damaged or has been in use for a long time, the slightest movement of it causes the contact to be interrupted, and charging stops. The issue here is not the battery, but the power supply.

These reasons are not so common, but they do exist.

What to do when the battery is not fully charged

The installation disk is often overloaded with useless utilities that slow down certain options. These include energy consumption control managers. Manufacturers install such programs to extend the life of the battery due to inadequate charging. If such a situation occurs, you need to find unnecessary applications and remove them. The name of such system add-ons contains the laptop brand plus a combination of words - Power Management.

To search for slowing utilities, just go through “Start” to “Control Panel” - “All Control Panel Items” - “Programs and Features”.

Find unnecessary applications and remove them. After completing the procedure, a reboot may be necessary.

Most of the proposed methods help to establish a relationship between the laptop and the battery. If you cannot fix the problem yourself, contact the service center. Then there is a possibility of hardware failure. Usually the controller burns out, which can only be replaced by professionals.

The battery is one of the key elements of any laptop or netbook. It is the battery that distinguishes a laptop from a desktop computer. And it is the battery that ensures the mobility of the laptop. If it is faulty, then the laptop is immediately tied to the outlet. Therefore, laptop owners are very interested in various issues related to the operation of batteries. Today we will look at several problems related to laptop battery. The main question addressed in this article is why the laptop does not see the battery. We will try to understand the causes of this problem and what to do in such a situation.

There is a situation when, when the battery is installed correctly, the laptop does not see the battery. At the same time, you are absolutely sure of the correct installation and normal contact between the battery and the laptop. If it does not detect the battery, then the icon in the taskbar is displayed with a red cross.

If you hover your mouse cursor over the battery icon, a message will appear: “Battery not detected.”

What could be the reasons for this message?

• Battery malfunction;
• Incorrect battery connection;
• Laptop motherboard malfunction.

To find out what's going on here, replacing the battery with a known working one will help. If the laptop sees the battery, then the problem is in the old battery. If the problem persists, then it is a malfunction of the motherboard.

But not everyone has a spare battery on hand. Therefore, below are ways to resolve this problem using what is at hand.

What to do if the battery is not detected on the laptop?

In principle, Windows may not detect the battery if everything is fine with the latter. But from the outside it looks like the laptop doesn’t see the battery. To check the battery status yourself, you can do the following:

• Reset hardware settings;
• Reset BIOS;
• BIOS upgrade;
• Checking to start a laptop on battery power without connecting to the network.

These operations are discussed in more detail below. If you need it, read the article at the given link.

Hardware reset

Resetting the hardware settings deletes all information that is in the temporary memory of the laptop. After this, the Windows operating system will definitely conduct a full scan of the laptop. Including the battery.

The following sequence of actions must be done to reset the hardware settings:

• Unplug the laptop's power supply or docking station, if equipped;
• Take out the battery;
• Then hold down the Power button for 15 seconds. Many users wonder why they need to press the power button on an unplugged laptop with the battery removed. This is necessary to remove the residual charge of the capacitors;
• Reconnect the battery and power supply to the laptop;
• Turn on the laptop and check the battery status in the Windows taskbar.

If the reset operation did not help, then move on to the next solution to the problem.

Checking to start a laptop on battery power without connecting to the network

HP recommends this option for its laptops. They advise running a laptop running on battery power without connecting to the network. If this is successful, then HP specialists advise reinstalling the operating system. This will reportedly help in cases where the battery is not detected on the laptop.

If the laptop refuses to start without a power adapter, then it has a direct route to a service center.

Other laptop battery problems

In addition to the fact that the battery is not detected on the laptop, there are also a lot of problems with batteries. Even if the laptop sees the battery, this does not mean its normal operation. Let's look at a couple of common faults.

The laptop turns off if it is not connected to the power supply

In this case, the Windows operating system sees the battery. If the power supply is connected, then when you hover the cursor over the battery icon, the message “charging” will be written. And when you unplug the power adapter, the laptop turns off.

What could be the cause of this malfunction?

• Incorrect battery installation. Remove the battery and install it again;
• Oxidation and contamination of battery contacts. Therefore, there is no normal contact with the motherboard. Wipe the battery contacts with a cloth soaked in alcohol. Then install it in place.

If a known working battery does not change the situation during installation, then this indicates a malfunction of the motherboard.

Battery charging stops if you move the power connector

The laptop sees the battery. The problem is that the power adapter charges the battery only in a certain position of the power connector.

What could be causing this?

• The laptop power supply is working, but the cable is faulty;
• The power supply and cable are working, but the power connector is faulty. It is subject to replacement, which must be carried out at a service center.

Some laptop models are equipped with power connectors on a flexible cable. In principle, you can replace them yourself, since soldering to the board is not required.

Rapid battery discharge after a certain value

The situation is approximately the following. The battery is detected on the laptop and is 100 percent charged. If you turn off the power supply, the battery works, for example, up to 50 percent and then very quickly discharges to zero.

The battery is one of the key elements of any laptop or netbook. It is the battery that distinguishes a laptop from a desktop computer. And it is the battery that ensures the mobility of the laptop. If it is faulty, then the laptop is immediately tied to the outlet. Therefore, laptop owners are very interested in various issues related to the operation of batteries.

• Turn on the laptop and check the battery status in the Windows taskbar.

If the reset operation did not help, then move on to the next solution to the problem.

Reset BIOS

If the battery is not detected on the laptop, then you can reset the BIOS to return the laptop settings to factory settings. To do this you need to take the following steps:

• When you turn on your laptop, press the button (key combination) several times to enter the BIOS on your model. Depending on the model or manufacturer, this may be Del, F2, F10, F12 and others;
• In the BIOS settings, find the option that is responsible for resetting the settings. These may be the following options: “Restore default settings”, “Reset settings to factory settings”, “Default settings” and the like;
• Then you need to confirm the reset, save the changes made and exit the BIOS.

After this, check the battery status in the operating system.

BIOS upgrade

If resetting the settings to default values ​​did not help and the laptop does not see the battery, then you can try updating the BIOS. Sometimes this can help if the battery on the laptop is not detected. To do this, you need to find the latest BIOS version for your model on the manufacturer’s website. You will also need a special utility for flashing the firmware. As a rule, all manufacturers produce similar software. Some manufacturers implement such utilities directly into the laptop's BIOS.

Attention! If you do not have experience in flashing BIOS, and do not clearly imagine the whole process, it is better not to take on this matter.

Checking to start a laptop on battery power without connecting to the network

HP recommends this option for its laptops. They advise running a laptop running on battery power without connecting to the network. If this is successful, then HP specialists advise reinstalling the operating system. This will reportedly help in cases where the battery is not detected on the laptop.

In this case, the Windows operating system sees the battery. If the power supply is connected, then when you hover the cursor over the battery icon, the message “charging” will be written. And when you unplug the power adapter, the laptop turns off.

What could be the cause of this malfunction?

• Incorrect battery installation. Remove the battery and install it again;
• Oxidation and contamination of battery contacts. Therefore, there is no normal contact with the motherboard. Wipe the battery contacts with a cloth soaked in alcohol. Then install it in place.

If a known working battery does not change the situation during installation, then this indicates a malfunction of the motherboard.

Sometimes the user has to deal with a message that the battery on the laptop is not detected. Often such a notification leads to panic, because it is the battery that ensures the mobility of the device, and even if there is an outlet nearby, it is not always possible to use it - an unstable electrical network will simply disable the laptop. So what to do?

Reasons why the error occurs

It happens that the battery is installed correctly in the laptop or it has not been touched at all, but on the taskbar the battery charge icon is crossed out with a red cross, and the laptop writes: “battery not detected.”

The main reasons for such an error can be three types of malfunctions:

1. Non-working motherboard.
2. Battery wear.
3. Battery connection is incorrect.

To avoid wear and tear, it is recommended to always have a spare battery on hand. If after replacing the battery the message disappears, it means that the problem was due to the service life. But not everyone follows this recommendation; more often, the owner of a laptop buys a battery after certain problems have appeared. And sometimes even after replacement the laptop writes: “battery not detected.”

What to do?

There are several ways: resetting the hardware settings, resetting the BIOS and starting the computer with a battery without connecting to the mains. Calibration programs can also help.

Each of the above methods will be discussed in detail in the following sections, however, if none of them helps, all that remains is

Reset settings

This action will help clear the laptop's temporary memory. The next time you start the laptop, the OS will conduct a full check of the equipment, including the battery. To reset the settings, you will need to disconnect the computer from the power supply, remove the battery and hold down the power button for 15 seconds to get rid of the residual charge. After this, you can return everything back and start the laptop, and then check for the “battery not detected on the laptop” notification.

If this operation does not help, you should resort to the next point.

Resetting BIOS

This action will help restore the laptop to factory settings, although if they were previously changed by the user, this is undesirable, since then you will have to spend time again on partially restoring the settings. It is especially unpleasant when the method does not help.

But if there is no other choice, you will have to sacrifice your time. To reset, you will need to enter the BIOS when you turn on the laptop (the specific key combination depends on the model) and find the section responsible for resetting the settings to factory settings. After confirming the operation, you need to exit the “input/output system” and wait for the OS to load.

If the battery on the laptop is still not detected, you can try to reflash the BIOS, but a beginner should not undertake this procedure, otherwise the computer will completely lose its functionality.

Starting a laptop without a network connection

You can try this method on any computer, but it will not always work, even if the battery is fully functional. As a rule, these are still problems with the motherboard, so nothing happens.

But this method is recommended when the battery is not detected on a laptop, HP for example. If the startup of the laptop is successful, the company’s specialists advise reinstalling the operating system - often this action helps to restore the correct operation of the equipment.

Battery not detected

For those who were not helped by the above tips, there is only a direct path to the service. However, if you don’t have a spare battery at hand, it’s worth checking the battery for dirt and oxidation of the contacts - perhaps this is what caused the malfunction.

Sometimes gadget owners wonder what “the battery is not detected on the laptop” means? Everything is quite simple: the laptop motherboard does not see the battery, because there is no proper connection of the contacts. Therefore, if the battery is completely new and the OS has not undergone any changes, there is no doubt about the cause of the malfunction.

Other problems

Sometimes a crossed out battery icon appears on a PC running Windows 7, but this does not mean that the battery on the laptop is not detected. Most often, the OS in this case requires replacing the battery, since it does not work correctly - it does not hold a charge, its real operating time no longer corresponds to the displayed indicators, or the laptop does not turn on at all without being connected to the network.

This problem is solved in 95% of cases by replacing the battery, and there is no need to panic when it appears - unless the laptop model is so outdated that batteries are no longer produced for it.

Other problems with the battery are usually solved in a similar way. If it doesn’t help, then you need to check the motherboard and then install new equipment or components. If the laptop does not turn on even with the power supply, first of all, you should try starting the PC from another charger. If the situation does not change, the connector may be faulty. Sometimes you can replace it yourself, since in some models it is not connected to the motherboard directly, but through wires, so it can be easily disconnected from it.

In this article, I will explain how to fix laptop battery charging problem. I'll list the most common examples of battery failure and suggest some troubleshooting steps.

Example 1.

The laptop recognizes the battery but turns off when the AC adapter is not connected.

When you move the cursor, click on the battery icon while the laptop is connected to the AC adapter, this will show the remaining battery power and say "charging".

If you click on the icon, a window will open which also shows that the battery is connected and charging.

But... as soon as you unplug the AC adapter, the laptop turns off completely.

Possible problems:
1.Battery is not installed correctly. Try connecting the battery again.
2. The battery contacts are dirty or oxidized and the battery does not have good contact with the motherboard. Try reconnecting the battery several times.
3. If reconnecting the battery does not help, the battery is most likely faulty and should be replaced.
4. If you have replaced the battery and the problem still exists, the motherboard is faulty. In this case, the entire motherboard must be replaced (or repaired at the component level).

Example 2.

The laptop does not detect the battery.

The battery is installed and you know it is making good contact, but there is a red cross on the battery icon.

If you move the cursor over the battery icon, a "battery not detected" message will appear.

Possible problems:
1. Most likely the battery is faulty. You have a very good chance to fix this problem by replacing the battery.
2. If replacing the battery does not help, it is a malfunction of the laptop motherboard. The motherboard must be replaced (or repaired at the component level).

Example 3.

The battery discharges very quickly after reaching a certain critical point.

The battery is detected by the laptop and shows 100% charge.
When you unplug the AC adapter, the laptop runs normally until some critical point (say 80%), but after that the battery drains very quickly to 0%.

Possible problems:
This is due to a faulty laptop battery. The battery is faulty and must be replaced.

Example 4.

The battery is charged only if the power connector is in a certain position.

You must move the plug in order to charge the battery. Once you find the correct position, the battery charges properly.

Possible problems:
1. The AC adapter is faulty. The AC adapter is OK, but the cable is damaged. You can test your AC adapter using a voltmeter.
2. If the adapter works fine, most likely the power connector (the connector in the laptop where you plug in the power adapter) is damaged. In this case, the power socket must be replaced.

In some laptop models, the power connector is not soldered to the motherboard; it is located on a flexible wire.

In this case, you can disconnect the faulty power connector from the motherboard and replace it with a new one.

A laptop is a compact mobile device that is capable of battery life for some time, which allows you to safely use a full-fledged computer even in places where it is not possible to connect to an outlet. Below is about the problem when the laptop does not see its own battery.

The duration of operation of a laptop without connecting to the network depends on the capacity and “newness” of the battery connected to the device. Unfortunately, over time, capacity will be lost, which means the laptop will work less and less on a single charge. But today the problem will be considered much more seriously - the problem has reached the point that the laptop does not see the battery at all. Such an error can be influenced by several factors, which will be discussed below.

Why doesn't my laptop see the battery?

Reason 1: battery failure

First of all, you need to suspect that the problem lies with the connected battery, and not with the laptop itself. You can check this only by trying to connect a similar but new battery to your laptop. If the laptop detects the other battery correctly, the old battery needs to be replaced.

Please note that some laptop manufacturers bundle their devices with proprietary utilities. So, if you are an HP laptop user, try finding and running the HP Support Assistant utility, which has a special tool for checking the battery. This function will allow you to find out without leaving home whether the problem is caused by a faulty battery, or whether the problem lies in the laptop itself.

Reason 2: operating system malfunction

Let's assume you rule out the possibility of battery failure. In this case, you should think that, most likely, the problem arose due to problems with the operating system.

1. System Restore

First of all, you can try to restore the system to the moment when the battery was detected by the laptop absolutely correctly. To do this, go to the menu “Control Panel” – “Recovery” – “Run System Restore” .

A window will appear on the screen with available recovery points, among which you will need to select the appropriate one, dated from the time when the battery was detected correctly by the computer.

2. System reinstallation

A radical, but also the most effective way to solve many problems, which will allow you to start running your computer “from scratch.” If possible, save all the necessary files to a disk on which Windows is not installed, upload them to the cloud or transfer them to a flash drive (external hard drive). After this, perform a complete reinstallation of the operating system using a boot disk or flash drive. If the problem was software, then after performing these manipulations the laptop will correctly detect the battery.

Reason 3: accumulation of residual charge

Another possible solution to the problem, which is suitable only for users of laptops with a removable battery.

The essence of this method is to carry out special manipulations that will allow you to reset information stored in the temporary memory of the laptop.

To do this, you will need to turn on your laptop completely and then unplug it. After this, you will need to remove the battery and press the power button on the laptop without a battery and hold it for 30 seconds.

After completing these steps, connect the battery back to the device and start the laptop. Check the functionality of the laptop.

Reason 4: Incorrect BIOS settings

As usual, a similar reason applies to users who have had to change BIOS settings. The essence of this method is to reset the BIOS settings to factory settings.

As a rule, you can reset the BIOS on a laptop from under the BIOS itself. To do this, turn on the laptop or reboot and at the very early stage of startup, begin to repeatedly press the button to enter the BIOS settings - as a rule, in most cases this is either the key F2, or Delete.

Having successfully entered the BIOS, you will need to find the item "Load Setup Defaults" or a slightly different but similar name of the item. Often such a function is located either in the section "Exit" , or in one of the main BIOS sections.

Reason 5: Outdated BIOS version

This problem scenario is listed last because it is the least common, since even the oldest BIOS versions usually work correctly.

However, if the first 4 methods of solving the problem did not work for you, then you should try updating the laptop BIOS.

As a rule, to do this, on the website of the laptop manufacturer you can download a special utility specifically for your model, which allows you to update the BIOS from Windows without any problems. However, you should be extremely careful about the power supply: if the laptop suddenly loses access to the network and the computer turns off right in the process of updating the BIOS, everything can end very sadly - the BIOS may even fail.

If you have your own experience in solving a battery problem, be sure to share it in the comments.
