The laptop does not see the acer battery. The laptop does not see the asus battery. The laptop does not see the battery. Uninstalling and Installing the Microsoft ACPI Battery Driver

Even a slight deviation in the work of a complex household appliances may indicate a serious software or hardware problem. For example, if the laptop has stopped seeing the battery, then you should not put off finding and fixing such a problem indefinitely, otherwise a complete failure of the computer may soon occur.

Maintenance

Which laptops are prone to problems

If it is almost impossible for a simple layman to conclude which laptop models are prone to battery failure, then computer service specialists can give the most comprehensive answer on this topic.

Repair shop employees note the fact that owners of both expensive devices and budget portable computers deal with laptop performance problems related to battery identification by the operating system.

The following laptop models are most susceptible to such a malfunction:

  • Machines
  • Lenovo
  • Packard Bell
  • Samsung
  • Toshiba

In addition, owners of domestic Aquarius laptops, which also use lithium batteries, often face similar problems.

If the laptop battery is no longer detected by the system, it is absolutely not necessary to seek help from specialists. Most of the reasons that cause this behavior of portable computers can be eliminated on their own.

Mechanical problems and how to solve them

If additional software is often needed to determine laptop software problems, then mechanical problems can be identified during a visual inspection.

Bad battery

A battery failure often causes the laptop not to see it. Lithium batteries have a limited number of charge-discharge cycles, so if the laptop has been used for many years, then it is enough to purchase a new battery for the operating system to start detecting the battery.

A new power supply can also be the culprit for such a malfunction, but only if the laptop was equipped with a defective element.

If the battery was previously charged with an adapter of the wrong type, then such actions could also cause the failure of this element with no identification by the operating system. Replacing the battery, in these cases, completely solves the problem of its detection by the computer.

Oxidation of contacts on a battery or laptop

Oxidized contacts may be the reason that the OS does not see the battery. In addition, the presence of a film with high resistance will lead to a rapid discharge of the battery. To determine such a malfunction is not difficult. It is enough to turn off the laptop, remove the battery and inspect the battery contacts.

Plaque that interferes with the normal functioning of the device can also be on the contacts of the laptop. If a dark or greenish film is found, clean the contacts on the battery with an eraser or a cloth soaked in alcohol.

Software problems and solutions

If the laptop battery is not detected, but no violations of its performance were found during a visual inspection, then most likely the cause of the malfunction is software failure. Such malfunctions can also be eliminated without the involvement of professional craftsmen.

Remove all new programs

Installing new programs may cause some services to not work properly operating system. First of all, utilities that perform the function of optimizing the power consumption of a portable computer can cause such a malfunction. Delete early installed programs in many cases completely solves this problem.

Update or reinstall battery drivers

If the removal of the utilities did not help restore the "vision" to the operating system and it again informs the user that the battery is not detected, then you should try updating the battery driver to the latest version. For this purpose, you can use special software or perform the operation yourself.

In windows 10, to update the driver manually, you must:

  • Go to device manager.
  • Find the battery in the list of connected equipment.
  • click right click mouse by battery name.
  • Select "Update driver".

The system will automatically search for the driver, including on the Internet. If a new driver was not found, then you can try to reinstall the existing device software.

For this you need:

  • Right click on the battery in device manager.
  • Select "Delete".
  • Restart laptop.

The next time you turn it on, the operating system will automatically detect the battery and install a suitable driver for its normal functioning.

Reverting the system to before the problem occurred

If the battery was previously detected by the laptop, then it is enough to perform a system restore to fully restore previous settings. To roll back the system in windows 7, you must:

  • Click "Start" then "Run".
  • Enter command:
  • On the System Protection tab, click the System Restore button.
  • On the next tab, select a restore point and click Finish.

As a result of such an operation, the system configuration that was saved earlier will be restored.

OS level crashes and how to fix them

If system restore did not help, then the most drastic measures should be taken, up to reinstalling the operating system.

OS reinstallation

To perform this operation, you will need boot disk with windows, which must be installed in the drive. Then you should restart the laptop and go into BIOS. In the window that opens, you need to find a section that displays the sequence for selecting boot disks.

To boot First, select CD-ROM. Then save the settings and try to boot from installation disk. Next, the system is installed in the standard way.

Restoring factory settings

This method will allow you to restore the laptop to working capacity only if the user has not previously reinstalled the operating system. During this operation, information from hard drive will be deleted, so you should save important documents on removable media in advance. Restoring the factory settings of the laptop is carried out in the following sequence:

  • The laptop turns on.
  • Key held down
  • In the window that opens, select "Windows setup".
  • Select the "Restore Windows to the first partition" option.
  • Press the "Finish" button.

BIOS level crashes and how to fix them

If the battery is connected correctly, but is not detected by the computer, then a faulty BIOS may be the cause of the laptop malfunction.

Reset settings

The easiest way to restore the system software is to reset the settings. This operation is performed in the following sequence:

  • Turn on laptop.
  • Enter BIOS by pressing the function key.
  • Go to the Exit menu.
  • Select Load setup defaults.
  • Press a key

Update BIOS

Sometimes you can solve the problem by updating the BIOS to a more new version. To perform this operation correctly, you must adhere to the following recommendations:

  • Go to the BIOS manufacturer's website and find the support section for your model.
  • Find latest version software.
  • Download the BIOS update utility.
  • Run the program on the computer.

The BIOS of the laptop will be updated automatically, but in order to prevent a failure during this operation, it is necessary to charge the battery in advance to the maximum value so that the device does not turn off at the most inopportune moment.

If the laptop writes that it does not see the battery, then you can almost always fix such a malfunction yourself. In most cases, it is enough to strip the contacts on the laptop or simply re-plug the battery.

Depending on the laptop model, the methods for solving the problem may differ, so if you still have questions or is there something supplement the article? Write about it in the comments. This will make the article more complete and useful.

Today we will look at:

A laptop or any other laptop is a very popular thing today due to its compact size and the presence of a battery that allows you to use this device in places where there are no sockets for direct connection to power. However, along with the presence of a battery, laptops also have corresponding problems, one of which is that at some point the laptop may stop seeing the battery. Of course, this is not a death sentence for your device and to prove it, we suggest you check out the article below where we will tell you how to fix this problem.

Why does the laptop not see the battery?

There are several reasons why this could happen:

  • failure of the battery itself;
  • errors in the operation of the operating system;
  • BIOS problems.

Each of these points requires a detailed explanation and suggests its own way of solving the problem, which we will talk about now.

Reason 1: battery failure

Battery health is the first thing to check. The fact is that no matter how carefully you use your laptop, its battery tends to lose charge, which is maintained by special lithium batteries inside. Therefore, the failure of any battery is just a matter of time.

First of all, you need to pull the battery out of the device and disassemble it. When the disassembled battery is already in front of you, pay attention to the contacts and the special blue “barrels” (they are the same lithium components): check if the contacts are burned out and examine each of the lithium batteries for performance. To do this, you will need to have a few tools with you.

Incidentally, more fast way how to check a laptop battery for a malfunction is to connect it to another suitable laptop (however, one will still need to be found, because each manufacturer has its own standards).

As for the manufacturers themselves, many conscientious developers install special utilities on their laptops at the production stage to monitor the operation of individual elements of the system. So, for example, many HP series laptops have a special HP Support Assistant utility that allows you to quickly check whether a battery problem is the cause of the problem or whether the laptop is the problem. If you have such a utility, use it immediately.

Reason 2: operating system errors

Quite often, software failures can cause hardware components to fail. There are only two ways out here: use a restore point or a complete reinstallation of the operating system.

About point Windows Recovery we've already said. Regarding reinstallation, here we recommend that you first create backup all required files. After that, you can install Windows in any way convenient for you.

Reason 3: BIOS issues

Considering this reason, it is worth understanding that if you have never changed the battery, then the BIOS itself cannot cause the laptop system to not recognize the battery. Another thing is when you have already changed the battery before. In this case, a certain conflict may arise.

However, if you often went into the BIOS settings and changed something there, then your actions could also affect the situation that arose. The first thing we recommend doing is resetting the settings to the default ones.

If resetting the settings did not help, then the next thing you can try is to update it yourself (this also applies to the situation when you previously changed the battery).

Outcome

All of the above methods for solving the problem when the laptop does not see the battery, in most cases, correct the situation. However, there is a possibility that the source of the problem is much "deeper" and everything that we talked about earlier simply will not help. In such cases, we recommend that you contact a specialist in service center who will accurately find the source of the problem and help fix it.

Many users often use their laptops without being connected to the network, working solely on battery power. However, sometimes the hardware fails 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 detailed look at the options for solving the battery detection error in a laptop.

When the problem in question occurs, system icon in the tray notifies the user about 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 solved.

Method 1: Update the hardware

The first thing to do is to restore the hardware, since the problem that has arisen could be caused by a small hardware failure. The user only needs to perform a few simple steps. Follow the instructions below and the update will be successful:


Resetting the hardware helps most users, but it only works if the problem was caused by a simple system crash. If the actions taken did not bring any result, proceed to the following methods.

Method 2: Reset BIOS settings

Certain BIOS settings sometimes cause incorrect operation of certain device components. Configuration changes can also lead to 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 by different methods, but they are all simple and do not require additional knowledge or skills from the user. Detailed Instructions by reset BIOS settings you will find in our article at the link below.

Method 3: Update the BIOS

If resetting the settings did not give any results, you should try installing the latest firmware 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 require some effort, carefully follow each step of the instructions. Our article describes the entire BIOS update process. You can get to know her at the link below.

In addition, in the event of problems with the battery, we recommend testing it through special programs. Often, malfunctions are observed in batteries, the life of which is already coming to an end, so you should pay 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 analyzed three methods that solve the problem of detecting a battery in a laptop. All of them require certain actions and are different in complexity. If no instructions have brought results, you should contact the service center, where professionals will diagnose the installed equipment and perform repairs, if possible.

Sometimes the user has to face a message stating 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 - unstable electrical network will simply destroy the laptop. So what to do?

Reasons why the error occurs

It happens that the battery is installed correctly in the laptop or it was not 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. Incorrect battery connection.

To avoid wear and tear, it is recommended to always have a spare battery on hand. If the message disappears after replacing the battery, it means that the matter was precisely in the service life. But not everyone follows this recommendation, much more often a laptop owner buys a battery after certain problems have appeared. And sometimes even after replacing the laptop writes: "the battery is 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 these methods will be discussed in detail in the following sections, however, if none of them help, only

Reset

This action will help clear the temporary memory of the laptop. The next time you start the laptop, the OS will conduct a full check of the hardware, 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 that, it will be possible to return everything back and start the laptop, in order to then check for the notification "battery on the laptop was not detected."

If this operation did not help, you should resort to the next step.

BIOS reset

This action will help to roll back the laptop to the factory settings, although if they were previously changed by the user, this is undesirable, since then you will have to spend time again on a partial restoration of the parameters. It is especially unpleasant when the method does not help.

But if there is no other way out, 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 "IO 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 working capacity.

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 motherboard, so nothing happens.

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

Battery not detected

For those who have not been helped by the above tips, there is only a direct road to the service. However, if there is no spare battery at hand, it is worth checking the battery for contamination and oxidation of the contacts - perhaps this was the cause of the malfunction.

Sometimes gadget owners wonder what does "battery not detected on laptop" mean? 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 on PC Windows control 7, a crossed-out battery icon appears, 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, it real time performance no longer matches the displayed indicators, or the laptop does not turn on at all without connecting to the network.

This problem in 95% of cases is solved by replacing the battery, and you should not panic when it appears - unless the laptop model is so outdated that batteries are no longer produced for it.

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

Notebook users know that when there is a problem with the battery, the system notifies them with the message “It is recommended to replace the battery on the laptop.” Let's take a closer look at what this message means, how to deal with battery failures and how to monitor the battery so that problems do not appear for as long as possible.

Starting with Windows 7, Microsoft began to install a built-in battery health analyzer in their systems. As soon as something suspicious starts to happen to the battery, Windows informs the user about it with a “Replace battery recommended” notification displayed when the mouse cursor is hovered over the battery icon in the tray.

It is worth noting that this does not happen on all devices: the configuration of some laptops does not allow Windows to analyze the state of the battery, and the user has to track failures on his own.

In Windows 7, the warning to replace the battery looks like this, in other systems it may change slightly

The thing is that lithium-ion batteries, due to their design, inevitably lose capacity over time. This can happen at different rates depending on the operating conditions, but it is impossible to completely avoid the loss: sooner or later the battery will no longer “hold” the same amount of charge as before. It is impossible to reverse the process: you can only replace the battery when its actual capacity becomes too small for normal operation.

The replace message appears when the system detects that the battery capacity has dropped to 40% of the declared capacity, and most often means that the battery is critically worn out. But sometimes a warning is displayed, although the battery is brand new and has not had time to grow old and lose capacity. In such cases, the message appears due to an error in Windows itself.

Therefore, when you see this warning, you should not immediately run to the parts store for a new battery. It is quite possible that the battery is in order, and the system posted a warning due to some kind of malfunction in itself. So, the first thing to do is to determine the reason why the notification appeared.

Checking laptop battery status

Windows has a system utility that allows you to analyze the state of the power supply system, including the battery. She is called through command line, and writes the results to the specified file. Let's figure out how to use it.

The utility can only be used with an administrator account.


The file consists of many notifications about the state of the elements of the power supply system. The item we need is “Battery: battery information”. In addition to other information, it should contain the items “Calculated capacity” and “Last full charge” - in fact, the declared and actual battery capacity at the moment. If the second of these points is much smaller than the first, then the battery is either poorly calibrated or has really lost a significant part of its capacity. If the problem is in the calibration, then to eliminate it, it is enough to calibrate the battery, and if the cause is wear and tear, then only buying a new battery can help here.

The corresponding paragraph contains all information about the battery, including the declared and actual capacity

If the calculated and actual capacities are indistinguishable, then the reason for the warning is not in them.

Operating system failure

Windows OS failure may well lead to incorrect display battery status and related errors. As a rule, if the matter is in software errors, we are talking about damage to the device driver - software module, responsible for managing one or another physical component of the computer (in this situation, the battery). In this case, the driver must be reinstalled.

Since the battery driver is a system driver, when it uninstalling Windows will automatically install the module again. That is, the easiest way to reinstall is to simply remove the driver.

In addition, the battery may be incorrectly calibrated - that is, its charge and capacity are displayed incorrectly. This is due to errors in the controller, which incorrectly reads the capacity, and is completely detected when easy use devices: for example, if the charge “falls” from 100% to 70% in a few minutes, and then the value stays at the same level for an hour, then something is wrong with the calibration.

Reinstalling the battery driver

The driver can be uninstalled through the "Device Manager" - built-in Windows utility, which shows information about all of the computer's components.


Battery calibration

Most often, battery calibration is performed using special programs - they are usually preinstalled in Windows. If there are no such utilities in the system, you can resort to calibration through the BIOS or manually. Third Party Programs for calibration can also help in solving the problem, but it is recommended to use them only as a last resort.

Some BIOS versions "can" calibrate the battery automatically

The calibration process is extremely simple: you must first charge the battery fully, up to 100%, then discharge it “to zero”, and then charge it again to the maximum. In this case, it is advisable not to use the computer, since the battery should be charged evenly. It is best not to turn on the laptop at all while charging.

In the case of manual calibration, the user faces one problem: the computer, having reached a certain battery level (most often 10%), goes into sleep mode and does not turn off completely, which means that it will not be possible to calibrate the battery just like that. First you need to disable this feature.

  1. The easiest way is not to boot Windows, but to wait for the laptop to discharge by turning on the BIOS. But this takes a lot of time, and in the process you will not be able to use the system, so it is better to change the power settings in Windows itself.
  2. To do this, you need to go along the path "Start - Control Panel - Power Options - Create a power plan". Thus, we will create a new power plan, working in which the laptop will not go into sleep mode.

    To create a new power plan, you need to click on the corresponding menu item

  3. During the setup process of the plan, you need to set it to "High performance" so that the laptop runs out of power faster.

    To drain your laptop faster, choose a plan with high performance

  4. You also need to prohibit putting the laptop into sleep mode and turning off the display. Now the computer will not "fall asleep" and will be able to shut down normally after "zeroing" the battery.

    To prevent the laptop from going to sleep and ruining the calibration, you need to disable this feature.

Other battery errors

"It is recommended to replace the battery" is not the only warning that a laptop user may encounter. There are other problems that can also be the result of either a physical defect or a software failure of the system.

Battery connected but not charging

A battery connected to the mains may stop charging for several reasons:

  • the problem is in the battery itself;
  • failure in the battery drivers or BIOS;
  • problem in the charger;
  • the charge indicator does not work - this means that the battery is actually charging, but Windows tells the user that this is not the case;
  • third-party power management utilities interfere with charging;
  • other mechanical problems with similar symptoms.

Determining the cause is actually half the job of fixing the problem. Therefore, if the connected battery is not charging, you need to start checking all possible failure options one by one.


Battery not detected

The message that the battery is not found, accompanied by an icon with a crossed-out battery, usually means mechanical problems and can appear after the laptop hits something, power surges, and other cataclysms.

There can be many reasons: a burned out or loose contact, a short in the circuit, and even a “dead” motherboard. Most of them require a visit to the service center and replacement of the affected part. But fortunately, the user can do something.

  1. If the problem is in a loose contact, you can return the battery to its place by simply disconnecting it and connecting it back. After that, the computer should "see" it again. Nothing complicated.
  2. The only possible software cause for this error is driver or BIOS issues. In this case, you need to remove the driver for the battery and roll back the BIOS to the standard settings (how to do this is described above).
  3. If none of this helps, it means that something has burned out in the laptop. You have to go to the service.

Laptop Battery Care

We list the reasons that can lead to accelerated wear of the laptop battery:

  • temperature extremes: cold or heat destroys lithium-ion batteries very quickly;
  • frequent discharge "to zero": every time the battery is completely discharged, it loses part of the capacity;
  • frequent charging to 100%, oddly enough, also has a bad effect on the battery;
  • operation with voltage drops in the network is detrimental to the entire configuration, including the battery;
  • constant work from the network - also not the best option, but whether it is harmful in a particular case depends on the configuration: if the current passes through the battery during operation from the network, then it is harmful.

Based on these reasons, it is possible to form principles for the careful operation of the battery: do not work in the "mains" mode all the time, try not to take the laptop outside in cold winters or hot summers, protect it from direct sunlight and avoid networks with unstable voltage (this battery wear is the lesser of the evils that can happen: a burned-out board is much worse).

As for the full discharge and full charge, Windows power settings can help with this. Yes, yes, the one that “takes” the laptop to sleep, preventing it from being discharged below 10%. Third-party (most often pre-installed) utilities will deal with the upper threshold. Of course, they can lead to a "plugged in, not charging" error, but if you configure them correctly (for example, stop charging at 90-95%, which will not affect performance too much), these programs are useful and will protect the laptop battery from excessively rapid aging .

As you can see, the notice to replace the battery does not necessarily mean that it is actually out of order: the causes of errors are also software failures. As for physical condition battery, then the loss of capacity can be significantly slowed down by following the recommendations for care. Calibrate the battery in time and monitor its condition - and the disturbing warning will not appear for a long time.
