The computer does not see the battery how to fix. Solving a problem with the detection of a battery in a laptop

Laptop is a compact mobile device that is capable of working a battery for a while, which allows you to safely use a full-fledged computer even in those places where there is no possibility to connect to the outlet. Below it will be about the problem when the laptop does not see its battery.

The duration of the laptop operation without connecting to the network depends on the tank and the "novelty" of the battery connected to the device. Unfortunately, over time, the container will be lost, which means that the laptop will be less and less and less from one charge. But today the problem will be considered much more serious - the problem has reached the fact that the laptop does not see the battery at all. A few factors may affect a similar error, which will be discussed below.

Why does the laptop sees the battery?

Cause 1: Battery failure

First of all, it is necessary to suspect that the problem is a connected battery, and not in the laptop itself. You can check it only by trying to connect a similar one, but a new battery to your laptop. If the laptop is another battery determines correctly, the old battery needs to be replaced.

Please note that some laptop manufacturers complete their devices by branded utilities. So, if you are a user of a HP laptop, try to find and run the HP Support Assistant utility, in which there is a special tool for checking the battery. A similar function will allow you without leaving the house to find out whether the battery has become the cause of the problem, or the problem is the laptop itself.

Cause 2: Operating system failure

Suppose you exclude the possibility of failure of the battery. In this case, you should think about what, most likely, the problem arose due to problems in the operation of the operating system.

Here we see two possible outputs from the situation:

1. Restoration of the system

First of all, you can try to restore the system by the time when the battery was determined by the laptop absolutely correct. To do this, go to the menu "Control Panel" - "Recovery" - "Running system recovery" .

A window appears on the screen with available recovery points, among which you need to choose a suitable, meanwhile when the battery is determined by the computer correctly.

2. Reinstalling the system


Radical, but also the most effective way to solve many problems that will start running a computer "from a clean sheet". If there is such an opportunity, save all the necessary files to the disk on which Windows is not installed, unload them into the cloud or transfer to the USB flash drive (external hard drive). After that, perform a complete reinstalling of the operating system using the boot disk or flash drive. If the problem was software, then after performing data for manipulations, the laptop will correctly determine the battery.

Cause 3: Residual Charge accumulation

Another possible way to solve the problem, which is suitable exclusively to users of laptops with a removable battery.

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

To do this, you will need to fully enable a laptop, and then turn it off from the network. After that, you need to remove the battery and click on the laptop without the battery button and keep it for seconds 30.

After executing these actions, connect the battery back to the device and run the laptop. Check the performance of the laptop.

Cause 4: Invalid BIOS Settings

As I was put up, such a reason concerns users who have been changed to change the BIOS settings. The essence of this method is to reset the BIOS settings to the factory.

As a rule, to reset the BIOS on a laptop in most cases can be from under the BIOS itself. To do this, turn on the laptop or send to the reboot and at the earliest start stage. Start repeatedly press the button to log in to the BIOS settings - as a rule, in most cases it is either key F2.either Delete..

Successfully entering the BIOS, you will need to find item "LOAD SETUP DEFAULTS" or a slightly different, but similar item name. Often, this feature is located or in the section "EXIT" , or in one of the main BIOS sections.

Reason 5: Outdated BIOS version

This version of the problem is given the last on the list for the reason that it meets less frequently, since even the oldest BIOS versions usually work correctly.

However, in the event that the first 4 ways to solve the problem did not come up, then you should try to update the BIOS laptop.

As a rule, for this, on the website of the laptop manufacturer, it is for your model that you can download a special utility that allows you to update the BIOS without any special problems from under Windows. However, it is necessary to be extremely careful in relation to the power supply: if the laptop suddenly disappears network access and the computer will turn off right during the BIOS update process, everything can be completed very sadly - the BIOS may also fail.

If you have your own experience solving the problem with the battery, then definitely share it in the comments.

The battery is one of the key elements of any laptop or netbook. It is the battery that the laptop differs from the desktop computer. And it is the battery that provides a laptop mobility. If it is faulty, the laptop immediately ties 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 associated with the laptop battery. The main question considered in this article, why the laptop does not see the battery. We will try to deal with the reasons for this problem, and what to do in such a situation.

It happens such a situation when when the battery is properly installed, the laptop does not see the battery. At the same time, you are absolutely confident in the correctness of the installation and normal contact of the battery and laptop. If it does not detect the battery, the icon in the taskbar is displayed with a red cross.

If you bring the mouse cursor to the battery icon, the message will be displayed: "The battery is not detected."

What are the reasons for this message?

  • Battery malfunction;
  • Incorrect connection of the battery;
  • Malfunction of the motherboard laptop.

To find out what the case is here, it will help the replacement of the battery on knowingly working. If the laptop sees the battery, then the reason in the old battery. If the problem remains, then this is a malfunction of the motherboard.

But not everyone has a spare battery at hand. Therefore, there are ways to resolve this malfunction with the help of what is at hand.

What if the battery is not detected on a laptop?

In principle, Windows may not detect the battery if everything is in order with the last. And from the side everything looks so that the laptop does not see the battery. To check the battery status yourself, you can do the following:

  • Reset hardware settings;
  • BIOS reset;
  • Upgrade BIOS;
  • Checking the launch of the laptop from the battery without connecting to the network.

Below these operations are considered in more detail. If you need, read the article at the specified link.

Reset hardware settings

Reset the hardware settings removes all the information that is in the temporary memory of the laptop. After that, the Windows operating system must complete the laptop full test. Including battery.

The next sequence of actions must be made to reset the hardware settings:

  • Turn off the laptop power supply or docking station, if available;
  • Remove the battery;
  • Then hold down the POWER button 15 seconds. Many users are asked why to press the power button on the laptop disabled from the network. It is necessary to remove the residual charge of capacitors;
  • Connect the battery back and power supply to the laptop;
  • Turn on the laptop and check the ACB status in the Windows taskbar.

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

Checking the launch of the laptop from the battery without connecting to the network

This option recommends doing HP for your laptops. They advise you to launch a laptop running from the battery without connecting to the network. If it succeeds, then HP experts are advised to reinstall the operating system. It is reported that this will help in the case when the battery is not detected on the laptop.

If the laptop refuses to start without a power adapter, then he is a straight road to the service center.

Other Notebook Battery Problems

In addition, the battery has not been found on the laptop, there are still a lot of problems with batteries. Even if the laptop sees the battery, it does not yet talk about his normal work. Let's consider a couple of widespread faults.

The laptop is turned off if not connected to the power supply

In this case, the Windows operating system sees the battery. If the power supply is connected, then a message will be written when you hover the cursor to the battery icon: "Charging". And when the power adapter is disconnected, the laptop turns off.

What could be the reason for this fault?

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

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

Battery charging stops if you move the power connector

The laptop sees the battery. The fault lies in the fact that the power adapter charges the battery only in a certain position of the power connector.

How can this be caused?

  • Notebook power supply worker, and the cable is faulty;
  • Power supply and operating cable, and faulty power connector. It is subject to replacement, which should be carried out in the service center.

Some model of laptops are equipped with power connections on a flexible wire. In principle, they can be replaced independently, since the soldering to the board is not required there.

Fast battery discharge after a certain value

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

From a stationary computer. After all, it is she ensuring the mobility of the device. Therefore, its breakdowns can significantly complicate the work of most users. It is important to know whether it is possible to fix them, and how to do it yourself. For example, what to do if the laptop writes: "The battery is not detected."

The reasons why the laptop does not see the battery can be quite a large number:

  • breakdown of contacts;
  • incorrect operation of the battery;
  • hardware problems.

In these cases, it must be replaced or make sure that it is inserted correctly. However, problems often concern the system errors. Let's try to figure out why the laptop does not want to see the battery.

These are those tips to help you determine the source of the problem. After them it is worth making further actions.

Battery Replacement

Try to replace the battery on knowingly working. This will quickly reveal where the problem is. After all, if the battery is to blame, it means it will have to change it to a new one. If the computer issues alert that the battery is not detected with other batteries, it means that it is not in the nutritional element.

Try to replace the battery

Similarly, you can try to mount a problem accumulator to another similar laptop. Here, again, the place of malfunction will be revealed. However, not everyone has a spare battery at hand, but the more laptop.

Check without connecting to power

This advice gives HP to its users. Disconnect the wire and run the laptop with the connected battery. The inclusion also witnesses about malfunctions with a laptop, and not with a battery.

If the computer functions, although the absence icon is lit, HP advises to reinstall the operating system. The way may approach the laptops from other manufacturers with the same problem.

Solutions

The tests shown at the top showed that the problem is in a laptop. What actions do next? There are several methods for solving the problem:

  • bIOS reset;
  • reset hardware settings;
  • reinstalling branded utilities.

Reset

After this operation, Windows will re-check all parts of the laptop.

  • Hold the power button within 15 seconds. It is necessary to make it in order to remove the residual charge.
  • Connect the battery and power supply back.
  • Turn on the device and check if the battery is displayed now.

If it did not help, the laptop does not see the battery as before, proceed to the next way.

Removal of additional utilities

There are special programs that could either be installed by the user himself or go along with the laptop. They "follow" for the economical use of the battery and in most cases, especially on new systems, only harm, since:

  • do not give the battery to charge to the end;
  • displays incorrect information about the status of the battery.

Check their presence on the PC is quite easy. The battery icon is modified and differs from the standard. In this case, you need to search such utilities and remove them.

Rollback to factory settings

Rollback to the settings from the plant is the zeroing of the BIOS specified above. It is important to understand that all user data will be deleted from the laptop. Therefore, it is necessary to take care of the preservation of important information on the network or on removable media.

  1. Turn off the computer.
  2. When you turn on, press one of the following keys: Delete, F2, F10, the keys can be different. The instructions for the device usually write how to enter the BIOS.
  3. Entering the BIOS find an item called "Reset Settings", "Restore default parameters", "Restore Defaults". Click on him.
  4. Click "Save" (Save) or Save and Exit.
  5. After leaving the BIOS, we turn on the laptop again. Together with the battery connected to the power supply.

It can not only help the BIOS zeroing, but also his flashing. Doing it yourself is not worth it, especially beginners. But if you are confident in your abilities and know how this operation is performed, download the latest version of the bios on the manufacturer's website and the upgrade utility.

Battery diagnostics

When charging problems, it will be necessary to check in what state is the battery. To do this, there is a special Batterycare application. On Windows 7/8 it is already installed. For the "dozens" you can download it yourself.

The utility shows several parameters of the battery. We are interested in the following:

  • declared container;
  • maximum charge;
  • battery wear.

Parameters AKB

The higher the difference between the declared container and the maximum charge, the less time the battery will work. The higher the wear, the higher the need to change this detail of the laptop.

Other problems

Cross on the battery icon

Akb never ceases to be detected. But Windows displays the battery with the red cross icon on it. This means that wear exceeded the permissible norms and the battery must be replaced.

If the battery is quickly sits on a laptop after a certain value, then the problem also lies in it. In this case, you again have to spend money on a new battery.

Charging is interrupted when you move the power connector

A fairly common problem on laptops used for several years. The point is not in the battery. And in the power supply or connector on the computer. It is necessary to replace the wire. If it does not help, you will have to attribute a laptop to repair and check the state of the connector, especially when the prominent defect is present on it.

Now you know what to do when the laptop does not see the battery. If the ways did not help, contact the service center. After all, this indicates more serious violations in the work, which can not be fixed independently.

What if the battery is not detected on the laptop and the reasons for this message

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


BIOS zeroing

If the battery is not detected on a laptop, you can return the laptop settings to factory items by zeroing the BIOS. For this you need to do the following steps:

  • When you turn on the 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, locate the option that is responsible for resetting the settings. These may be the following options: "Restore default settings", "Reset settings to factory", "default parameters" and the like;
  • Then you need to confirm the reset of the parameters, save the changes made and exit BIOS.

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



Upgrade BIOS.

If the reset parameters for default values \u200b\u200bdid not help and the laptop does not see the battery, you can try to update the BIOS. Sometimes it can help if the battery on the laptop is not detected. To do this, it is necessary on the manufacturer's website to find a fresh version of the BIOS for your model. It will also require a special firmware utility. As a rule, all manufacturers produce a similar software. Some manufacturers implement such utilities directly in the BIOS laptop.

Attention! If you do not have experience in the BIOS firmware, and you can not imagine the entire process, it is better not to take for this business.

Checking the launch of the laptop from the battery without connecting to the network

This option recommends doing HP for your laptops. They advise you to launch a laptop running from the battery without connecting to the network. If it succeeds, then HP experts are advised to reinstall the operating system. It is reported that this will help in the case when the battery is not detected on the laptop.

Other Notebook Battery Problems

In addition, the battery has not been found on the laptop, there are still a lot of problems with batteries. Even if the laptop sees the battery, it does not yet talk about his normal work. Let's consider a couple of widespread faults.

The laptop is turned off if not connected to the power supply

In this case, the Windows operating system sees the battery. If the power supply is connected, then a message will be written when you hover the cursor to the battery icon: "Charging". And when the power adapter is disconnected, the laptop turns off.

What could be the reason for this fault?

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

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

Sometimes the user has to face a message that the battery on a laptop is not detected. Often, such a notification leads to a panic, because the battery ensures the mobility of the device, and even if there is a socket nearby, it's not always possible to use it - an unstable electric network simply will withdraw a laptop out of order. So what to do?

The reasons for which an error occurs

It happens that the battery is installed in a laptop true or did not touch it at all, but on the taskbar, the battery charge icon is crosslined with a red cross, and writes a laptop: "The battery is not detected."

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

  1. Non-working motherboard.
  2. Battery wear.
  3. Incorrect battery connection.

To exclude wear, it is recommended to always have a spare battery at hand. If, after replacing the battery, the message will disappear, which means it was precisely on the service life. But not everyone complies with this recommendation, much more often the laptop owner buys the battery after the emergence of certain problems. And sometimes after replacing the laptop writes: "The battery is not detected."

What to do?

There are several ways: reset hardware settings, zeroing the BIOS and run a computer with a battery without connecting to the power grid. Calibration software can also help.

Each of the above methods will be disassembled in detail in the following sections, however, if none of them will help, will remain only

Reset

This action will help clean the temporary memory of the laptop. If you start the laptop, the OS laptop will fully check the equipment, including the battery. To reset the settings, you will need to turn off the computer from the power supply, remove the battery and press the power button for 15 seconds to get rid of the residual charge. After that, you can return everything back and run a laptop so that you check the presence of the notification "Battery on a laptop is not detected."

If this operation does not help, it is necessary to resort to the next item.

Zeroing bios

This action will help to roll back the laptop to the factory settings, although if they were previously changed by the user, it is undesirable because then you will have to spend time on partial recovery of parameters. It is especially unpleasant in the case when the method does not help.

But if there is no other way out, you will have to sacrifice your time. To zero, it will be necessary to enter the BIOS when the laptop is turned on (the specific key combination depends on the model) and find the section responsible for resetting the settings to the factory. After confirming the operation, you need to exit the "I / O" system and wait for the OS load.

If the battery on a laptop is not detected still, you can try to reflash the BIOS, but it is not necessary to take a newcomer for this procedure, otherwise the computer will not lose the computer at all.

Launch laptop without network connection

You can try this method on any computer, but it will not always work, even if the battery is fully working. As a rule, it is still a problem 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 launch of the laptop is successful, the company's specialists advise to make a reinstalling of the operating system - often such an action helps resume the correct operation of the equipment.

The battery was not detected

Those who did not help 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 the presence of contaminants and the oxidation of the contacts - it is possible that this caused a malfunction.

Sometimes the owners of the gadget are asked what means "battery is not found on a laptop"? It's pretty simple: The laptop motherboard does not see the battery, since there is no proper connection of contacts. Therefore, if the battery is completely new, and the OS has not been subjected to any changes, there is no doubt due to malfunction.

Other malfunctions

Sometimes the PC under the control of Windows 7 appears the stumbled battery icon, but this does not mean that the battery on the laptop is not detected. Most often, OS in this case requires replacement of the battery, since it works incorrectly - it does not hold the charge, its real operation time no longer matches the displayed indicators or the laptop does not turn on without connecting to the network.

This problem in 95% of cases is solved by replacing the battery, and it is not necessary to panic when it appears - except the model of the laptop is outdated so hard that the batteries are no longer released.

The remaining malfunctions with the power element are usually solved in a similar way. If it does not help, it means checking 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 a PC from another charger. If the situation does not change, it may be faulty connector. Sometimes it can be replaced independently, since in some models, its accession to the motherboard is carried out not directly, but through the wires, so it is freely disconnected from it.
