Hp Laptop Battery Does Not Charge

Diagnostics of the battery itself

You can also programmatically diagnose laptop battery efficiency. Run for this command term as administrator and enter the command:

  • Powercfg / batteryreport

Then follow the specified path, in my case C: /Windows/system32/battery-report.html and run the report. You can copy the path from the command line and paste it into the address bar of the browser, as the report is in html.

Contacts on the battery

Remove the battery from the laptop and pay close attention to the contacts on both the battery itself and the laptop. Clean them from dust and dirt, if any. Also, pay attention if all the contacts are in place, and not broken off or bent terminals.


Press the WinR keyboard shortcut and enter devmgmt.Msc to open the device manager. Find and expand the “Batteries” column. Right click on each of them and select “Remove Device”. Now remove the battery itself from the laptop and wait 1 minute, then insert it back, and then connect the charger. Drivers Should be automatically reinstalled, if this did not happen, then right-click on the empty field and select “Update hardware configuration”.

Battery troubleshooter

If the block is not detected when using a Windows 10 laptop, then open “Options” “Updates and Security” “Troubleshoot” Case Start “Power”.

In Windows 7 go to “Control Panel \ All Control Panel Items \ Troubleshooting \ System and Security \ Power”.

Reset BIOS to default

Communicating with one of the users in telegram, we managed to solve the problem by resetting the BIOS to default. We will NOT go into details of what he overclocked and tried to configure there, but it helped to solve the problem with detecting the battery on the laptop. When you just turned on the laptop, press the DEL or F2 button continuously immediately to get into the BIOS settings. Different laptop models may have different login buttons.

Once you get into the BIOS, the reset is usually in the “Exit” tab called “Load Setup Default”. Press F10 to save parameters.

Checking the charger

A NOT working laptop charger may NOT work properly. In my case, it was an imperceptible micro-short circuit of the wires, which then demolished the drivers and system files responsible for software monitoring of the battery. If you have an electrician you know, let your device ring, or inspect it very carefully yourself. Also, if you have another charger, then you can use it.

Block not detected on Asus, HP or Acer laptop

When working on a laptop with Windows 10 or Windows 7, you may encounter the message that the block was not detected. The culprit for this problem can be both hardware and software. In most cases, this is due to the deterioration of the laptop battery itself, or the contacts do not contact the laptop well due to dust. Also, there were software cases like the battery device driver or some third-party software could disable the battery in the task manager. The battery detected message can appear on any laptop model, be it Asus, HP or Acer. Let’s take a look at what to do and how to fix it when a laptop running Windows 10 or Windows 7 displays a message that the battery has been detected.

Technical moment

For example, you bought a laptop in 2020 and want to use the Winows 7 system, or vice versa, you want to install Windows 10 on an old 2010 laptop. The fact is that battery management in new laptops does not come from standard ACPI, but through your own device. for which a driver is needed, and the official driver is only for Windows 10.

In this case, updating the BIOS sometimes helps. You can find the firmware on the official website of the laptop manufacturer. I solved this problem with the HP Pavilion 15 laptop. The HP Pavilion 17 laptop showed battery life when using Windows 7, but it was fine with Windows 8 and 10. Laptop BIOS update resolved battery detection issue.

Laptop battery is NOT charging, reasons!

In order to understand why the laptop battery is not charging, load the operating system and check the battery status. To check if the factory reset worked, you need to pay attention to the system report on the remaining time and% battery charge. The main thing is that the status “Connected, charging” should be displayed.

If you still can’t reset the settings, then look for a problem or defect in the battery itself. If the battery is not detected by the laptop, but it functions perfectly without a power supply and the battery charging process is visible, then most likely there is a problem with the controller. In this case, the battery must be replaced.

And here are the main problems that are inherent in batteries:

  • Physical deterioration. A typical lithium-ion battery is capable of about 800 recharge (charge-discharge) cycles, i.e. Work for 2-3 years (depending on the manufacturer). Gradually chemical reactions make the contents of the battery unusable.
  • Poor battery power supply, short circuit in the network. The battery consists of modules combined into a single controller. It is enough for one module to fail, and the whole mechanism of battery operation stops. Such cases allow for battery recovery.

As usual, in each article, I highly recommend that you familiarize yourself with such articles as: how to open the djvu file, and I also recently wrote where you can download it to your computer, as well as how to change the date in ios, and I did NOT forget about the article how to change the password in Miley.

Now you understand why the laptop battery does not charge. If you have any questions, ask them in the comments. I’ll be glad to help!

Laptop battery is NOT charging?

Today I will help you figure out why the laptop battery is not charging. Of course, the battery can become unusable over time, but such problems sometimes happen in brand new laptops. In this case, I would NOT advise you to rush to buy a new battery. Maybe it’s just a system glitch.

Earlier, I already wrote what to do if your laptop turns on and off immediately. Now just try to reset BIOS settings and remove the charge from the laptop motherboard. You can also read about BIOS signals. In order to reset the configuration on the laptop, first disconnect the power supply from the laptop, and then disconnect the charger.

And hold down the power button for one minute.

Next, connect the charger to the laptop (do not insert the battery). Turn on the laptop and go to the BIOS menu by pressing one of the buttons: F2. DEL or F12. In the window that opens, find the item “SET DEFAULTS or Setup (Restore) Defaults”. Apply default settings, save them and exit BIOS.

Then the laptop will need to be turned off. To do this, hold down the power key for 7-10 seconds. Unplug the laptop from the power supply and insert the battery. Now you can connect the charger and turn on the laptop.

Evgeny Kryzhanovsky’s blog. I will teach you how to repair your computer! Laptop battery not charging? : 24 comments

The article is useful for me personally. Recently I was faced with the fact that the battery was not charged on the laptop. As I was not a shaman, it still did not work to fix it. I gave it to a service center, replaced it. For the future I will use this article.

Damn, thanks. Recently this started, I unplug the adapter from the socket and the laptop immediately turns off. I really wanted to go and read the laptop. I was told 1000 rubles for diagnostics. Thank you very much for helping

I have such a problem with the old ASUS. I went through all the mechanical steps, but I was afraid to climb into the BIOS. I will invite a specialist. But thanks!

Thanks to the author for the excellent article. For a long time he could solve this problem, but it did not work out. I read the article and it worked out for me.

Hello. I have a question. And when the laptop is constantly connected to the outlet. Does it somehow affect the battery life or not? Or do you need to take it out of the laptop? And in general, how should the battery be properly operated in this case? thanks.

Mikhail, of course, that the constant connection of the laptop to the network significantly reduces the life of its battery, therefore it is recommended to pull it out while the laptop is connected to the network in its operating mode.

And why the laptop battery does not work tell me

I have a good laptop, they did NOT use the laptop for a long time, and when I turned it on, the battery indicator turned red and after a few seconds it went out. The battery name is pa3534u-1brs. I understand a little about this in general, the batteries themselves are normal in general, they give out more than 10v. But it does not pass through the controller to the outputs at all by zeros. How to bypass the controller to charge and run on battery.

Artem, try the following:
1. Disconnect from the stationary power supply;
2. Disconnect the charger from the laptop;
3. Take out the battery;
4. Press the laptop power button and hold for about a minute;
5. Connect the charger to the laptop (without battery)
6. Start the device and go to the BIOS menu (Usually you need to press one of the buttons: F12, DEL, F2)
7. In the BIOS menu, find the item “SET DEFAULTS or Setup (Restore) Defaults”.
8. Apply the default BIOS settings and save before exiting;
9. Turn off the laptop (press the power button or hold it down for about 5-7 seconds)
10. Disconnect the laptop from the charger and insert the battery;
11. Connect the charger and start the laptop;

Useless. I also tried to delete the driver. there is a result.

Please tell me what to do if the BIOS has “SET DEFAULTS and Setup (Restore) Defaults” ?
The laptop works only when the charging is on, as soon as I plug it out, it is cut down (when it is on the charge it is written connected, it charges how much it costs 0% I did everything as in the article, but in the BIOS SET DEFAULTS and Setup (Restore) Defaults I don’t have (( maybe they can be called differently? Tell me who knows please.

Hello. I have hp pavilion g6. the problem is SIMilar. The laptop is new. Does NOT react to the charger, even the light does not light up. Completely DISCHARGED, cannot even turn on.
Huge request: Tell me at least something

After completing step 5, I pressed the power button, the laptop blinked two lights and went out completely. Now it does NOT react to anything, the lights do not burn at all. What to do?

Hello! I have such a problem that the laptop battery does not charge when it is turned on, only when it is turned off it charges, and then very slowly. In two days, somewhere 50% only charged, then I turn on the computer back, the battery sits down after a while and turns off n. Can you help me. ((

What if the battery is non-removable? She is somewhere inside, I can not take anything off myself. I DO NOT want to carry it to the service. Battery stopped charging after upgrading to windows 10 from figure eight.

Anna, how did you solve this problem? I now have the same problem the laptop does NOT charge after the update

And if the battery is built in then what to do.

Writes connected, charging. But it doesn’t charge. After rebooting, the charge goes on for a few seconds. The unit is not removable.

READ  Screen share LG how to connect laptop

I have the same thing as in Andrey. Supposedly “connected, charging”, but in fact it is not charging. Only the battery is removable, new. Help me please!

Hi! The reason is this! You turn on the charging, it starts charging, it writes connected, it charges, then it starts flashing, then it charges, then it discharges, the ambassador does not charge, you pull out the charging plug, plug it in, again the same garbage! But! In the off state, the battery is charged normally and completely! This garbage became after I installed Windows 10!

And I also forgot, when you take out the battery and start turning on the computer just on the charger, it starts to load and after 5-10 seconds it turns off!

Interestingly, however, I didn’t succeed. I have
Sony Vaio-VPCEB19FX. The battery is dead, I bought a SIMilar one.
Says “0% available, connected, charging”,
however, charging is available. Charging goes to how the computer is fully
boot, then skiff. Are there any more ways?

Hello, tell me when we reinstalled Windows the battery did not get stuck it says 52% It does not get stuck and it is written and charging the laptop immediately turns off. BIOS has already reset the ASUS laptop, the battery is built-in, that is, NOT removable, the laptop itself is not new year, and such is the problem.

Good afternoon. Tell me pzhsta, I have the same problem, and the battery is not charging, but at the same time, even when the OS is turned on, the laptop does not work for me. I move my battery to another good one, charging does not work like that, but the beech is expressed in 10-20 seconds and does NOT want to work.

How does the beech model depend on whether it works with a dead battery or not. Or why one beech works with her and the other comments?

How to setup?

Everything about the Internet, networks, computers, Windows, iOS and Android

Why is the laptop battery (battery) connected but not charging??!

Hey. For the day, they brought me an Acer laptop on which there was a problem with the battery. it SIMply did not take charge when the charger was connected. Confused by the fact that the laptop itself, although inexpensive, is also NOT old. only 1.5 years. Of course, you can kill a laptop or netbook battery in less time. But here everything depends on the conditions and correct operation. For example, I have an old HP Compaq laptop, which has been working for more than 7 years and it still has a living battery, which keeps charging up to 35-40 minutes. For such an old man, this is more than great.

Deterioration is one of the main reasons for the failure of laptop batteries, because it has a certain limit of charging / discharging cycles, and when it depletes, it usually just “ends up”. Even the manufacturer in the manual most often writes that the battery life is 2-3 years. The point is that in about the first year it loses a fifth of its capacity, and by the end of the second year it may SIMply fail. The cases when she lived longer than three years can, roughly speaking, be counted on the fingers. And the only way out is just to replace the laptop battery.

But there are cases when the battery has stopped charging on an almost new laptop and the operating system writes that “The battery is connected but not charging”:

The reason may be a banal failure of the operating system or the controller on the motherboard. You can try to do the so-called “full reset” of the computer BIOS settings.
To do this, let’s try to do a few SIMple steps.
Turn off the laptop and disconnect the charger from it.

Then removing the battery.

Press the laptop power button (Power) and hold it pressed for about a minute.

This is done in order to remove the remaining charge from the capacitors.

Connect the charger to your laptop or netbook. Leave the battery NOT connected for now.

We turn on the laptop and go into the BIOS. To do this, press the Del or F12 button. On some models, the F2 or F5 key may be used to enter the BIOS. Look at the labels when loading. As a rule, it indicates which button to press.

Go to the “SaveExit” section and select the item “Load Setup Defaults” or “Restore Defaults”:

In some BIOS versions, this item may be located in another section, for example, “Boot”. After that, we restart the laptop. And as soon as it starts loading again, turn it off with the “Power” button.

Disconnecting the charger, I return the battery to its place and connect the charger.

We turn on the laptop and wait until it boots.
If you are lucky and after resetting the parameters, the laptop battery comes to life. great! If not, then except for replacing the battery. there is no way to solve the problem and replacement is the only way out.

As a conclusion, I want to give a method that is often resorted to in order to keep the battery efficient for the longest possible period. It consists in the fact that when you work at home or in the office, that is, where the work on the battery is not needed. just Disconnect the battery and connect the laptop directly to the network through the charger. If the laptop is used as a regular PC and it is always connected to the electrical network, the battery can be disconnected and removed altogether.

Software malfunctions

First you need to check if the malfunction is the result of some software glitch. It is likely that the battery is still charging, only this is not shown by the indicator. Restart your PC and look at the battery charge indicator. If you have installed third-party power management software before, uninstall it. The laptop still won’t charge? Check if everything is ok with the ACPI drivers. Go to Device Manager, find and expand the item “Batteries”. Look to see if the “Microsoft ACPI Compliant Battery” device is marked with a yellow icon, however, even if the device works fine, uninstall the driver and restart the computer. But the absence of the “Batteries” item in the device manager will indicate a hardware failure of the power board or contacts.

Problems with drivers often arise after installing Windows updates, so if the battery stops charging after the next system update, download the original software for the chipset and power management from the laptop manufacturer’s resource and install it.

Incorrect initialization of the battery

If you bought a new laptop with a preinstalled OS and found that the laptop is not charging from the charger, the battery may not be initialized correctly. After turning off the laptop, turning off the charger and pulling out the battery, press and hold the power button for 15-20 seconds. Then insert the battery, connect the power supply, wait 10-15 minutes, turn on the device and check the battery in the system. This method is universal for all laptop models. Asus, Acer, Samsung and others.

Another way to get the laptop to detect the battery normally is to reset the BIOS to factory defaults. You can resort to it if the unit does not charge on the laptop after some system failure or replacement of the old “native” battery with a new one. Repeated the actions described in the previous paragraphs up to holding the power button, Connect the laptop through the charger to the network (insert the battery), turn on and enter the BIOS, holding the corresponding key at the moment of turning on.

To enter BOIS in different laptop models, different keys can be used, for example, in HP it is F10 or Esc, in Asus and Acer, Lenovo, Dell and Samsung. F2 or Delete. In the settings of the basic I / O system, you need to find the option “Load Defaults”, “Load Optimized BIOS Defaults” or “Restore Defaults” and use it to reset the parameters to the original.

After that, turn off the laptop, turn off the power supply, insert the battery and turn on the device again. Check if charging is correct by connecting the charger to the laptop.

Faulty battery, controller or power circuit

Finding the answer to the question why the battery on a laptop does not charge is often NOT within the power of an ordinary user. The lack of reaction of the laptop to the connection of the charger and the actual charging during normal indication may also indicate a malfunction of the battery, controller or power circuit in any of its nodes. If all attempts to find and eliminate the cause of the problem were unsuccessful, it’s time to contact the service center.

The battery has reached the end of its life

If the battery is old and quickly discharged before that, it is likely that the moment has come for it to finally lose its ability to accumulate and store charge, although in principle the indicator in the system tray should indicate the charging procedure. In any case, such a battery must be replaced. The same applies to the battery, after lying without work for a long time: if they are not regularly recharged, they can fail.

Hardware faults

The laptop is not charging the battery, and charging connections. where else to look for the cause? Are you sure that the problem is in the battery? Eliminate breakdowns and damage to second devices. charger, cable and contacts. First of all, make sure that the battery is installed correctly in the connector. Remove the battery and carefully inspect it for damage and swelling, check the quality of the contacts: over time they can oxidize.

We also check the socket, plug and other elements of the power circuit. Many chargers have an LED indicator, if it does not light up, this may indicate a breakdown of the charger. To completely eliminate this moment, Remove the battery and try to turn on the laptop from the mains. If the laptop isn’t working, that’s right, the problem is not with the battery, but with the power supply. Alternatively, try charging the battery with a guaranteed working charger with SIMilar output parameters.

Laptop battery does NOT charge at all

“Well, everything, something is covered, you need to urgently run to the service center, or even buy a new battery”. the first thing that usually comes to mind for a user who has encountered a problem. Yes, such a scenario is not excluded, but you shouldn’t rush, perhaps nothing serious happened, and the problem can be solved on your own. The situation when the laptop battery is connected, but not charging, can be caused by many reasons, and often they are related not only to software, but also to hardware. An ordinary user can eliminate the first, but in the second case, most likely, you will have to resort to the help of a specialist.

Laptop battery is NOT charging. how to solve the problem?

Compactness would remain the only advantage of laptops, if they were NOT equipped with a battery or otherwise a battery. It provides the necessary autonomy, allowing for some time to work in the absence of power supplies in the access zone. On average, a laptop battery lasts for four hours of active work, which is not so much compared to smartphones and tablets, so the laptop has to be recharged regularly. Apart from the gradual decrease in power consumption, the battery usually does not have problems, however, one day users may unexpectedly find that the laptop battery is not charging.

When the laptop battery won’t fully charge

The case when the laptop battery does not fully charge, or at least the charge indicator shows this, requires separate consideration. The reasons for this phenomenon may be the limitations on the percentage of charge pre-installed in the laptop, as well as controller errors, due to which the real capacity of the battery does NOT coincide with the values ​​determined by Windows. As for the preset limits, they are set either at the BIOS level or at the level of proprietary utilities integrated into the system. Go into the BIOS of your laptop and look under the “Advanced” section for the “Battery Life Cycle Extension” option. To disable restrictions, set its value to “Disabled”.

READ  The laptop does not pick up the WI-FI signal well what to do

In the system itself, you should look for such a utility as Power Management, although it may be called something else. Battery Life Extender, Battery Long Life, etc. Typically, the names of such power management managers begin with the brand of the laptop, for example, for Samsung, it will be called Samsung Battery Manager. Go to the manager’s settings, find the battery management option and Remove all restrictions. As for controller errors, here the problem is solved by calibrating the battery. manual or software.


So, we figured out why the laptop battery often does NOT charge. If you happen to encounter such a problem, start looking for the reasons with the SIMplest and most obvious things. checking cables, memory and contacts. After that, you can go to software settings, including BIOS settings. If I suspect that the reason is still in the hardware, then do not try to fix the problems yourself, unless we have the appropriate skills and do NOT understand electronic computer circuits. Well, DO NOT forget that when replacing equipment, at least the same charger, it is very important that all technical parameters of the new device meet the requirements of the computer, otherwise the correct operation of its components is NOT guaranteed.

Overheating of the battery. causes, effects, solutions

The problem arises if the owner of the gadget did not keep the cooling system clean. As a result, the dust accumulates in a dense layer and the battery, along with the entire device, SIMply overheats. Also, this defect can occur if you use the device in stuffy / dusty rooms. In a hot season. this is one of the first reasons on the list why the laptop battery won’t charge.

How to tell if a battery is overheated? When the device is turned on, it charges quite normally for a certain period of time, and then the message “the unit is not charging” appears. This is a sure signal of its overheating. What are the solutions? First of all, it is necessary to clean the device from dust accumulations. To do this, you should contact a laptop technician.

In addition, special laptop stands will save the battery from overheating. They help to cool the device as a whole, and therefore, extend the life of the gadget.

An important tip in the end: The laptop should not be placed on soft surfaces (such as beds or sofas) so as not to block the ventilation holes.

Battery connected. charge available

The age of the device and its manufacturer do NOT play any role here. Samsung, Xiaomi, Prestigio or other laptops are equally affected by this problem.

The defect is identified as follows. in the notification area next to the icon, indicating the charge, a message is displayed with the text: “connected, not charging.” Users of “Windows” (version 10) will read a slightly different message: “Charging is not in progress”.

The first cause of the problem is software anomalies that only a specialist can figure out. What can you do yourself? The universal method is to “reset” the BIOS.

This is done in 10 steps:

  • Turn off the device completely.
  • Take out the battery.
  • Disconnect the gadget from the network.
  • Hold the power key on (1 min).
  • Connect the device to the mains (without battery).
  • Press the power key and go to BIOS.
  • Reset to factory defaults (EXIT menu. Load Defaults).
  • Save changes and turn off the gadget.
  • Disconnect the power supply cord from the laptop.
  • Return the battery to its place, connect the charger.

At the end, it remains to turn on the device (user settings will be saved) and observe its operation. If everything is done correctly, then “Windows” will please the user with a message: “connected, charging.” In case of failure, it is worth studying the following sections of this material and apply other methods of eliminating breakdowns.

Laptop does NOT charge: 5 main reasons and more than 10 solutions

What is the reason that the laptop suddenly stopped charging? Can this be fixed without calling a repairman? This article discusses the 5 most common problems with charging a device that users encounter, as well as ways to fix them on their own.

New laptop. the unit does not want to charge

Assembly-only devices have a pre-installed licensing system. In this case, the battery of a brand new laptop does not charge for 2 reasons: a factory defect or incorrect battery initialization.

You can help the device like this:

  • Turn it off;
  • Disconnect the gadget from charging;
  • Take out the battery;
  • Hold the ON key (20 sec)
  • Return the battery to its place;
  • Connect charging.

The only thing left to do is to turn on the device and make sure it works correctly.

A couple more tips for those who have a removable battery. For example, an elementary method:

  • Disable charging completely;
  • Remove the battery from its compartment;
  • Press and hold the power key for 1 minute.

Then you need to sequentially perform the steps: return the battery. turn on the charger. wait 15 minutes and turn on the device. All.

New variation of the previous method:

  • Disconnect charging with the device switched on, DO NOT touch the battery.
  • Press and hold the power key to turn off the device.
  • Connect the power supply.
  • Wait a quarter of an hour.

The procedure ends with turning on the device. Thus, you can cope with the problem yourself, without involving a master. 3 more common problems and their elimination are discussed below.

Battery charge does not reach 100%

Most of the manufacturers of laptops develop and install specialized software on devices to monitor and control the consumption / condition of the battery. Most often, these “optimizers” are the culprit for incomplete charging.

In such utilities there are 2 modes of battery operation, the first of them saves energy and does not allow to fully charge. Switching to the second mode will restore 100% charge. A radical solution is to disable or completely eliminate the utility.

If the last procedure did not help, then the matter may be in the natural wear and tear of chemical elements, failure of controllers, oxidation of contacts. In this case, it will not cope with the problem on its own.

Does the laptop NOT charge? The software is to blame!

The creators of devices often stuff devices with various utilities. Their purpose is to increase the performance and lifespan of devices. The reverse side of the coin is that the battery charge does NOT reach 100% because of this. The same goes for the official software where the error has crept in. You can deal with this by finding and eliminating unnecessary software.

Finding harmful utilities is easy:

  • Name “Start”. “Control Panel”;
  • Go to “Programs and Features”;
  • Select Unnecessary software (hint: it’s easy to recognize a software pest. its name contains a laptop brand)
  • Select it with the mouse button and click “Delete”.

Securing success is worth rebooting the gadget.

In the end, all of the above methods are effective in 90% of cases of troubles in charging a laptop. Even beginners can use these instructions to help the gadget get back to work. If, despite all efforts, the charging is NOT working out, then the problem lies in the equipment itself: wear of the charger, lack of power, problems with connectors on the laptop, and more. In this case, only a wizard will be able to find out why a Lenovo, ASUS, HP or second-brand laptop is not charging.

A common glitch: the battery on a laptop stopped charging

Those who often deal with computer equipment have long been aware: “glitches” and buggies can occur for no apparent reason. This is true both in relation to the OS (and not only Windows) and the hardware. The good news is that the overwhelming majority of such “breakdowns” can be eliminated using a banal overload of the device. If the laptop writes: “the battery is connected but not charging”, it will not be superfluous to disconnect the battery and put it back in. To do this, just turn the device upside down and open one or two latches holding the battery. Remove the battery so that its contact connectors stop touching the pins of the laptop, then plug it back in. The next time you turn it on, the device should work normally.

Why the laptop won’t charge the battery: method two

If this happens, while charging the connections, the owner can help out by resetting the BIOS settings. This is explained by the fact that after a failure, the device may incorrectly detect the battery. This often happens if the user leaves a laptop or netbook connected without a battery, and also changes the “native” battery for a new one. To reset BIOS settings, you will need:

  • – Turn off device.
  • – Remove the battery (see above).
  • – Disconnect the charger from the network.
  • – Press the power button of the device and hold it for 60 seconds.
  • – Connect laptop to a power outlet without battery.
  • – Press the power button, enter BIOS.
  • – Find the Load Defaults item (most often found in the EXIT menu). This will allow you to apply the default hardware settings, that is, the optimal for this device.
  • – When the BIOS prompts you to save your settings, click Yes, then Turn off the device. To do this, just hold the power button for 10 seconds.
  • – Disconnect the charger, then insert the battery and turn on the device.

Usually, after executing such a SIMple aLGorithm, Windows reports that the battery has been detected and is charging correctly.

The battery on the laptop is NOT charging. what to check first

Users of portable PCs, namely laptops or netbooks, often face one common problem: when the laptop is turned on, the unit does not charge. At the same time, the LEDs work, the device does NOT display critical error messages and works almost normally. The only difference is that a message about the battery hangs in the tray: “connected, not charging.” How to make the battery on a laptop charge, we will consider in this manual.

Laptop battery does not fully charge: what to do?

Manufacturers often shove various useful utilities onto the installation disk, which serve to increase the device’s performance or its life. These include energy managers. These programs serve to extend battery life, almost always due to incomplete charging. This is the main reason why the laptop battery does NOT fully charge.

If the battery on your laptop is charging 60 percent or less, it is worth looking for and removing excess software. Usually, such programs contain the brand of the laptop in the name. For example, if the battery on an acer aspire laptop does not charge, you should look for the Acer Power Management utility, and if an incomplete charge goes to an asus laptop, then, accordingly, Asus Power Management.

To find these utilities, launch Control Panel after clicking the Start button.

All software is located under “Programs and Features”

Select a utility that does not allow you to fully Get battery power, and click the “Uninstall” button. Device may need to be rebooted.

Your Setevichok. New battery: why the laptop battery is not charging?

If these methods did not help and you decide to buy a new battery, an unpleasant surprise may await you here. If a new laptop battery is plugged in but does not charge, first of all, make sure that the markings on the new part match the markings on the old one exactly. If everything is correct, in most cases the aLGorithms described above help.

READ  How to increase the frequency of the processor on a laptop

All of these methods help in most cases when the laptop battery is dead and is NOT charging. When, after your “dancing with a tambourine”, the laptop still does not see the battery, intervention in the hardware will be required. perhaps the power controller has burned out. And it is better to entrust the procedure for its replacement to experienced specialists.

What to do if a block is not detected on a laptop?

In principle, Windows may NOT detect a battery if the latter is okay. And from the outside it looks like the laptop does not see the battery. To check the battery status yourself, you can do the following:

  • Resetting hardware settings;
  • Resetting the BIOS;
  • BIOS upgrade;
  • Checking laptop startup from battery without connecting to the network.

These operations are discussed in more detail below. If you need a program to calibrate laptop battery, read the article at the specified link.

Why the laptop does not see the battery?

Why the laptop does not see the battery

The battery is displayed with a red cross

If you move the mouse cursor over the battery icon, the message “Battery not found” will be displayed.

Message: “Battery not detected”

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

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

But not everyone has a spare battery at hand. Therefore, the following are ways to resolve this problem with what is at hand.

Fast battery discharge after a certain value

The situation is approximately as follows. The battery was 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 problem here is almost always related to battery failure. In this case, the battery must be replaced.

BIOS upgrade

If resetting the parameters to default values ​​did NOT help and the laptop does not see the battery, then you can try updating the BIOS. Sometimes it can help if the laptop battery 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 the firmware. As a rule, all manufacturers produce SIMilar software. Some manufacturers implement such utilities directly in the laptop BIOS.

Attention! If you do not have experience with BIOS firmware, and do not clearly understand the whole process, it is better not to take up this business.

Resetting hardware settings

Resetting the hardware settings deletes all information that is in the temporary memory of the laptop. After that, the Windows operating system will definitely carry out a complete check of the laptop. Including battery.

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

  • Unplug the laptop power supply or docking station if available;
  • Take out the battery;
  • Then hold down the Power button for 15 seconds. Many users wonder why they should press the power button on a disconnected laptop with the battery removed. This is necessary to remove the final 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.

Laptop shuts down if not connected to 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, a message will be written: “charging”. And when you disconnect the power adapter, the laptop turns off.

What could be the reason for this malfunction?

  • Incorrect battery installation. Take out the battery and reinstall it;
  • 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 put it back in place.

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

Resetting BIOS

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

  • When turning on the laptop, press the button (key combination) several times to enter the BIOS on your model. Depending on the model or manufacturer, it can be Del, F2, F10, F12 and others;
  • In the BIOS settings, find the option that is responsible for resetting the settings. These can 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.

Then check the battery status in the operating system.

Checking laptop startup from battery without connecting to the network

This option is recommended by HP for its laptops. They advise starting a laptop running on battery without being connected to the network. If this succeeds, then HP experts advise you to reinstall the operating system. It is reported that this will help in the case when the block is not detected on the laptop.

Battery charging stops when you move the power plug

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

How can this be caused?

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

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

Problem: The battery on the laptop stopped charging

It happens that a device that used to charge normally stopped doing it at some point. The laptop is working and the battery is connected correctly, but not charging. This is confirmed by the absence of an inscription when you hover the mouse over the battery status icon in the tray. There are three ways to solve the problem.

Problem: Laptop battery is connected but does not fully charge

The problem manifests itself as follows: the battery is charged, but does not reach 100%, i.e. DOES NOT fully charge. The operating time of the device from one charge is sharply reduced. For example, it worked up to 4 hours, and now it works only 40 minutes.

Method 3. if the power supply does not work

Another prerequisite may be the loss of performance of the power supply and a decrease in the reliability of its plug. In this case, the battery has nothing to do with it. It’s easy to check.

  • Turn off the laptop, Unplug the power supply from the socket.
  • Take out the battery, insert the plug of the power supply.
  • Plug the power supply into a power outlet.
  • Press the power button.

If after that the laptop does not work, then the power supply or its cord is out of order. Also, an old power supply may NOT provide sufficient current to operate the laptop and charge its battery at the same time. Such a device must be replaced.

Battery replacement (if necessary)

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

What to do if a new battery won’t charge

A much more difficult situation is when only the installed new battery on the laptop does NOT charge at all. To begin with, we advise you to do the BIOS reset operation described above.

Diagnostics of programs on a laptop

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

Open the Task Manager by pressing CtrlShiftEsc and Analyze the CPU usage of background programs. Sort applications in the list by CPU usage and watch for a while. Removing unnecessary programs running in the background will increase battery life.

Check the battery status

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

Three main parameters of battery health are important to us.

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

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

Method 2. removing “useful” utilities

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

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

Method 1. reset battery settings in BIOS

  • Disconnect power. Unplug the power supply plug from the device or unplug it from the power outlet.
  • Take out the battery. In models with a removable battery, and there are most of them, for this, it is enough just to turn the device over and move one or two locking devices that hold it.
  • Press the power button and hold it in this state for about a minute.
  • Insert the plug of the power supply into the laptop and connect it to the mains. In this case, it is not necessary to install the battery in place yet.
  • Turn on the laptop and enter its BIOS. To do this, at startup, press the key or their combination indicated in your user manual. Typical solutions: Del, F12 or F2.
  • Reset settings to preset value, Restore Defauts, and save BIOS settings, Save and Exit.
  • Turn off the laptop by holding the power button for 5-7 seconds.
  • Turn off the power supply again and Reinstall the battery.
  • Insert the charging plug and plug the power supply into an outlet.
  • We turn on the laptop in the usual way.

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