Battery not charging on HP laptop

Table of Contents

Damaged adapter

You can check the performance of the laptop charger using a multimeter. To do this, switch the device to the DC current measurement mode, plug the adapter into the network and touch the meter probes to the output contacts of the plug. A device malfunction is determined if the device does not show the rated voltage, which is indicated on the charger label.

To completely eliminate errors, you should connect the adapter to a different outlet, if the device indicators do not change, then this will indicate a malfunction of the charger. The converter cannot be repaired, so you will need to purchase a new adapter, but if the culprit is a plug or wire, then it can be repaired on your own.

Viruses

Viruses can invade the system files of the computer, causing various problems, including in the field of providing the battery with electric current. This problem is eliminated with the help of a high-quality antivirus program.

Problems with the wire or adapter

If the adapter is the cause of the problem, you will need to replace the charger to fix the problem.

The laptop won’t fully charge: Causes and What to do

The basic rule when self-repairing expensive electrical equipment is a minimum of actions, in the effectiveness and safety of which there is no absolute certainty. The optimal strategy for eliminating this kind of malfunction is to exclude, in the first place, the most probable causes that led to an incomplete battery charge.

Damaged wire

To establish the unsuitability of the device for repair, it is enough to cut the cable at the converter, then strip the wires and check the presence of electric current again.

battery, charging, laptop

If the tester shows the rated voltage, then the fault will be the cable. This problem is eliminated very easily: it is enough to replace the cable section from the converter to the plug with a new wire of the same cross-section.

Damaged plug

If, after the new cable is installed, the device does not charge the laptop battery again, then the adapter plug is most likely damaged. Such an element cannot be repaired, so it will need to be replaced.

You can take a working plug from a burnt-out charger with a similar connector or purchase a new one. To restore the adapter’s performance, it will be enough to solder, observing the polarity, a new element.

Aggressive exploitation

Aggressive use can also lead to insufficient battery charging. In this case, the battery is not fully charged due to the lack of electrical power of the adapter.

HP laptop battery is not charging

HP is a wonderful computer, but it can give you some trouble, or even terrible problems! Here is one of the typical problems faced by hobbyists and HP users and tips on how to solve this problem.

Why did this happen to me? How did I deserve this? Oh my God! This is terrible!

There are typical expressions you use when you are nervous and grab your head when you suddenly discover that your precious HP laptop battery is not charging. Well, this is life. after all, even the person you love more than anyone else in the world cannot always come to the rescue exactly when you need him, so it is quite fair that an inanimate and inanimate device that consists of microchips, wires and microcircuits, and not flesh and blood, can let you down, nullifying all your optimism and plunging you into despondency!

I agree, it all sounds too dull and melodramatic, but these are the words of a person who too often encounters equipment malfunctioning! Well, good! Stop whining! Let’s now talk to the point. The problem where the HP battery won’t charge even though the computer is plugged into an electrical outlet is quite common for older HP fans. So let’s take a look at the various aspects of this issue.

Why my HP laptop battery won’t charge even though the computer is plugged in?

Well, let’s say you plugged your HP into a power outlet and set off to go about your business with complete confidence that your laptop will be fully charged when you return. However, this did not happen, and when you returned, you found that your laptop battery was not charged even though the computer had been plugged in for over an hour. Basically, the laptop shows no sign of being charged at all! Well, there can be several reasons for this problem. The most likely reason is that your HP battery has expired. If you have been using your laptop for several years now, it is very likely that it is time to replace the battery. In addition, if the battery is badly worn out due to prolonged use, your HP’s battery life can run out much faster if you charge it unnecessarily, i.e. if it is not completely discharged. Doing this for an extended period of time will cause your laptop battery to wear out faster and need to be replaced.

Another reason the HP laptop battery may not charge is possibly because the connector pins are loose in the wall outlet. Press down on the plug more firmly, or try using a twin or multi-pole plug that matches the pins of the adapter connector. A loose plug is also a common reason the battery won’t charge.

The cause of the problem may also be the connector or the adapter itself, and in this case, you yourself decide whether to replace it or not. You can easily determine if this is the cause of the problem if the connector or adapter indicator light does not come on when plugged in. Also, if the cause of the problem is with the power control unit, reconfiguring it will help solve the problem.

Only a purchased HP laptop won’t charge the battery? Well, try reinstalling the battery in the cell. If that doesn’t work, you may have to take your laptop, along with the battery, adapter, and more, to the nearest HP service center. We hope our tips will help you! If not, please contact HP!

The battery does not charge on an HP laptop, although the laptop says that the battery is connected and charging: causes and solutions to the problem

There are times when an HP laptop recognizes the charger is plugged in, but the battery is not charged. Why it happens? There are many reasons for this: from a malfunction of the battery itself to software and hardware failures. We will talk about the main problems and ways to solve them in our article.

Reasons for which the battery is connected, but there is no charge

If after connecting the charger the message “Battery connected but not charging” appears, the following may have happened:

  • the network adapter is broken;
  • the battery needs to be recalibrated;
  • BIOS malfunctions;
  • software problems;
  • the working resource of the battery is exhausted;
  • motherboard problems;
  • use of “heavy” applications.

If your HP laptop displays a message saying that it is not charged, but the battery is recognized, this means that the device also recognizes the connected AC adapter. But this does not mean that it is serviceable. To test how the adapter works, try connecting another device to it. If it works, then the laptop is broken. The pins in the power connector may have come off. If the adapter doesn’t work, just buy a new one.

Resetting the BIOS settings often helps. To perform the migration, you need to do the following:

  • Disconnect charger.
  • Remove battery.
  • Press the start button and hold it for 15 seconds.
  • Wait 2-3 minutes and connect the PSU to the HP laptop, and then immediately to the mains without installing the battery.
  • Turn on the computer and open the BIOS by pressing Del, F12, F2.
  • Reset settings, save.
  • Turn off the laptop and install the battery.
  • We reconnect the laptop to the charger and power supply, start it up.

This method almost always helps. After performing the above manipulations, the battery begins to receive a charge in normal mode.

If the HP laptop battery is recognized but does not charge, and the charger and battery are working, and there are no software glitches, call the service wizard. To do this, call 7 (495) 146-65-51. We work around the clock.

If your HP laptop does not charge the battery, the reason is probably hidden in the factory utilities. They are installed to conserve battery life. But it also happens that it is the utilities that cause the lack of battery power. Your job is to find these apps. To do this, open the Task Manager and see what programs are currently running. If the utilities are to blame, the battery icon on the display will be different from the standard one. A third-party utility (Battery Mode, Battery Care, BATExpert, etc.) must be detected and removed from the Programs and Features menu, which opens through the Control Panel in the Start menu.

Other software issues include failed drivers or low-level settings. You can troubleshoot low-level parameter failures as follows:

  • Unplug HP laptop, remove battery.
  • Hold the power button and hold it for a minute.
  • Connect the charger and turn on the laptop.
  • When the operating system starts to load, open the BIOS.
  • Find the item Load Default Settings or Load optimized defaults in BIOS, apply it.
  • Save settings (Exit and Save changes).
  • Turn off the computer, then install the battery, charger and turn on the laptop.

If the reason was hidden in the wrong low-level parameters, charging should work in the previous mode.

What if the problem occurs with a brand new battery and it refuses to charge? Try resetting your BIOS first. Did not help? It is worth checking the labeling of the battery and make sure that the battery is compatible with your model of equipment. To avoid compatibility problems, it is better to purchase a new original production battery and, upon purchase, take your laptop with you.

To preserve the battery’s working life, charge it correctly: connect to the power supply when the charge level reaches 5% and disconnect only when it rises to 100%.

Each battery has a specific working life, calculated for a specific number of charging cycles. If the resource is exhausted, the battery needs to be replaced. When the battery is worn out, the message that there is no battery charge appears rarely. Most often, a quick discharge indicates a malfunction. In any case, the element will have to be replaced. Better to install the original battery, which will last longer.

This is quite a serious breakdown. The motherboard is one of the main components of a laptop. It can break down for various reasons. Microcircuits, controllers, resistors can burn out on it. You can determine the malfunction if you connect a practically new and serviceable battery. If, after all the manipulations with the driver updates, resetting the parameters, the charging problem persists, it means that the power circuits on the board are definitely damaged.

It is very difficult to repair a component on your own. This requires specific skills and knowledge. You need to contact the service center, where they will diagnose the device, and then either replace the board completely or repair it.

If all devices and components of technology have already been tested, it is worth looking for the reason in “heavy” applications running in the background. It is likely that it is they who consume the charge almost completely. To identify such software, you need to open the Task Manager and analyze which applications are currently using the processor. This will help you determine what is draining your battery instantly. Close the application or uninstall and the situation will be resolved.

If none of the above steps helped to get your HP laptop battery charged, it’s time to contact a service center. The service wizard will conduct a free device diagnostics, accurately determine the nature of the breakdown, and then eliminate it in a short time.

Do not install third-party applications on your laptop from unverified manufacturers. Better to use licensed software. This will prevent the possibility of infection with viruses and exclude malfunctions during the operation of equipment components.

New laptop battery won’t charge

An infrequent but very unpleasant situation when a new laptop battery does not charge. When it comes to a new battery, the first thing to do is to visually assess the markings on it.

It must be identical to the one printed on the old battery.

Another likely reason for a new laptop battery not charging is incorrect initialization of the battery. You can identify and solve this problem with your own hands by doing some simple steps:

  • Shut down the device and turn off the power.
  • Disconnect the battery.
  • Forcibly turn off the device using the button and hold it for about 30-40 seconds.
  • Install the battery back.
  • Connect the power and start the laptop.

After you have done all the manipulations, and the laptop is connected to the network, but does not charge, there is only one reason. a manufacturing defect. Here it will not be possible to solve the problems on your own, you need to contact the official representative for a warranty replacement.

What to do if your laptop won’t charge:

  • Hold the power button for about 60 seconds.
  • Connect the power supply (without battery) and start the device.
  • Open your laptop settings. BIOS. How to do this is written on the screen of your laptop at the very beginning of the download. Most often, this is done by pressing the Del button.
  • You will need to reset the default settings. Select Restore Defaults or Load Defaults. Then select Save and Exit to save and exit.
  • Without waiting for the download, turn off the laptop using the button.
  • After disconnecting the charger, replace the battery.
  • Plug in the adapter and restart the laptop.

If you have followed all the steps described above correctly, after the device is fully loaded, you will no longer be disturbed by messages about an uncharging battery. If, after the performed manipulations, the laptop battery does not charge, you should not get upset and run for a new power source. With a high degree of probability, you may have difficulties in the operation of the power adapter itself. Over time, they can deliver less power than is needed to run the laptop on AC power and charge the battery at a time. Therefore, it is recommended to replace the adapter and test the power supply again.

Laptop battery not charging

Many people who use laptops for work or entertainment are familiar with the unpleasant situation. the laptop battery does not charge. over, this can happen both with a used model and with a completely new technique. Guided by the fact that the battery is a consumable, many are in a hurry to replace it with a new one. But first, you need to find the root cause, because there are a lot of explanations for the fact that the laptop is not charging. These are technical difficulties and systemic problems, or mechanical damage. Solving individual problems may require contacting the service, however, many situations can be solved independently. The main thing is to correctly identify the problem.

We have analyzed the situations that laptop users most often face, and below we will tell you in detail what actions you can take to solve unpleasant situations with the battery on your own.

Laptop battery is connected but not charging

One of the most popular situations among users is that the laptop is running on AC power, but not charging. In other words, the power supply is installed correctly, the laptop is working, but it does not react to the charge in any way. over, when you hover the pointer over the icon showing the charge level, the following message is displayed: “Connected, not charging.” Let’s analyze the probable reasons why the laptop does not charge.

The main problem may be a software problem that only a specialist can handle. What can be done without resorting to the help of service workers? The optimal and rather effective method that does not require special skills is to reset the BIOS to default settings.

Step 1: Check the status of the power supply

So what if your laptop battery won’t fully charge? It is important to check the condition of the battery correctly. This can be done with the free Battery Care program.

If you have an iOS laptop, you can use the free Battery Health utility.

Having launched these programs, we select three main parameters of the battery state for analysis:

  • Initial nominal battery capacity. This is exactly the power that the battery had before use.
  • The maximum charge is the current capacity of the battery.
  • Battery wear percentage. The higher this indicator, the greater the need for replacement.

By checking the condition of the battery, as well as its current charge level, you can conclude that it is worn out and the need to install a new power source.

Laptop battery does not fully charge

It happens that the laptop battery is connected, but does not fully charge. Unlike when there is no charge at all, in this case the device is charged, but not to the maximum. In addition, the battery life of the device is significantly reduced. For example, a laptop worked for 5 hours on a single charge, and started working for no more than 1 hour. Let’s take a look at three basic steps to help you identify and fix problems.

Driver and Chipset Issues

The battery may not consume power due to problems with the operating system and its updates. For example, yesterday, the battery was charged as usual, but today the laptop does not respond to charging, and there were no system updates. Try following a few steps below:

  • Go to Device Manager
  • Find the ACPI Compliant Battery (or similar name) under the Batteries section. If there is no such item, this is the first sign of a problem.
  • Using the reboot function, restart the laptop.

Another option is that the laptop does not charge due to reinstalling the operating system or installing large updates. In this case, the device may not have enough drivers to correctly detect the battery. To fix this problem, you need to download and install the power management drivers.

Overheating of the battery

The answer to the question “why the laptop is not charging” may lie inside the device itself. Large amounts of dust accumulate in a dense layer on the cooling heatsink, causing the laptop to overheat.

A lock is triggered and the system stops charging, so as not to aggravate the situation and not harm the battery. Also, overheating of the laptop and turning off the battery charge can be the use of the device in dusty, unventilated rooms, high room temperature.

How to understand that this is the problem? Initially, the laptop works like a clock, charges normally, but at one point a notification pops up that the battery is not charging. This is one of the main criteria that the device is overheating. There may also be another situation where the laptop battery 0, connected, charging. This suggests that it is time for the device to take preventive measures and clean the radiators from dust deposits.

Also, to reduce the degree of heating and avoid situations when the laptop battery is not charging, you can use special stands.

They allow you to cool the device, and therefore reduce the load on the processor and battery. Another important tip: do not place your laptop on soft surfaces like a sofa or bed, as they block the ventilation holes.

BIOS or software problem

If the error started to be displayed recently, after changing the software on the laptop or reinstalling the OS, then you should check the software. You may need to reinstall the chipset drivers. It is important to download them from the manufacturer’s website (both motherboard and laptop). There is one more method to fix this problem: find the battery in the “Manager” and remove it, and then restart the computer. If it is not there, then it may be defective.

Problems with power management can also be the cause. This is associated with earlier versions of the BIOS, which, as a rule, is eliminated later by an update. But it also happens that a failure has occurred in the BIOS: a sign is system reboots at regular intervals or a constant hum of the cooler. Therefore, the first thing to do is reset it. On the BIOS start page, select boot settings. If it didn’t work, go to the laptop manufacturer’s website and find the BIOS update, download it and install it.

When you download the update in the archive with the installer, you will find a text file. This is an instruction, you need to follow the recommendations indicated there. All diagnostic measures are best done before the red low battery indicator starts blinking and the laptop stops turning on.

Checking the power supply

Check the power supply sections to find the problem. For this:

  • Check the serviceability of the surge protector from which the laptop is powered. Plug in the lamp, if it works, then this is not the reason.
  • The next step is to check the power supply. Remove the battery, if it works without it, then everything is fine with it. If not, it’s about charging.

Repairing a laptop connector is tricky due to its location on the motherboard. It is not recommended to change it yourself.

The charge goes, but not to the end

Most manufacturers install special software that is designed to monitor battery performance. These programs are often the reason your HP laptop won’t charge up to 100 percent.

When using such utilities, the battery can operate in two modes. The first one is designed to save energy, and therefore does not allow the battery to be fully charged. In this case, just stop using the utility. If this does not work, then the cause may be a malfunction of the batteries. There is wear of elements, breakdown in the controller or oxidation of contacts. A weak charge is often observed. In this case, contact the service department.

Software reasons for the failure

The most common variant of the problem: the status in the Windows notification area contains a message about the power being supplied from the network. It says: “Error. Charging is not in progress. ” A common reason is a failure in the software of the device.

HP notebook does not charge

If your HP laptop does not charge, look for the cause in the electronics or software. To understand whether you need to contact a specialist and replace computer parts, consider the most common problems.

Device problems

In half of the battery charging failures, there is an electronics problem. It happens that the battery does not charge, but the indication indicates the opposite. Software methods are suitable for solving the problem. If they do not improve the situation, then the reason is the following:

  • Charger defective or lack of power if using other charger. Pay attention to the indicator, if it does not light up, then the power supply unit malfunction is likely.
  • Problems with the connector: breakage of contacts or their oxidation, sometimes they can simply come off. This is noticeable by this sign: if you move the wire, a charge appears, often then the battery is charged slowly.

There may be no notifications in the OS, but there may be an icon indicating that the laptop is powered by battery.

Motherboard problems

The failure of the laptop motherboard is considered a bad sign. Repairing it is difficult due to the small size of the circuit elements and specialized chips. You can detect a breakdown in the following way: connect a working power supply unit to a laptop.

If the problem persists, it is most likely that the power circuits are faulty; it will not be possible to fix this without special skills. Better to take your laptop for repair. You can find a master in our service center.

On a new laptop

If the laptop is new and the licensed OS is already installed on it, the reason that the battery is connected but not charging may be a defect in HP. You can suspect a similar problem if it did not start charging immediately after the first turn on.

Another common cause is battery initialization failure. To fix it, follow the sequence of steps:

  • turn off the laptop and disconnect the charger and battery from it;
  • press the power button for 15-20 seconds;
  • put the battery back in place;
  • you can turn on a laptop with a battery.

These steps are easy to follow, but not always helpful. There are two more variants of the described method:

  • If the battery is removable: disconnect the power supply unit, remove the battery, hold the button for a minute. Connect the battery, then charge, then charge for 15 minutes and then turn on the laptop.
  • Disconnect charging without removing the battery, hold the power button until shutdown, connect the charger and wait 15 minutes, after which you can turn on the device.

If there is no result, it is better to take the laptop to a specialist.

What to do if the phone shows charging but not charging?

If the phone shows that charging is in progress, but does not charge as a result, it is possible that the controller in the main board has failed. In this case, you just have to contact the service center for a complete check of the device and replacement of its boards.

What to do if your laptop won’t charge?

What to do if the laptop battery does not charge

  • Resetting in BIOS Power off the notebook, unplug the AC adapter from the device or unplug it from the wall outlet, then remove the battery.
  • Uninstalling the utilities Some notebook models have preinstalled utilities that monitor the charging status.
  • Replacing the power supply The power supply itself or the plug is defective.

Is it possible to charge the laptop when it is turned off?

The following condition is also important in determining how to properly charge a laptop. it is best to charge the battery with the computer turned off. Firstly, this will allow you to charge it much faster than when the computer is on, and secondly, it will save the battery capacity.

How to test your HP laptop battery?

Checking the battery with HP Support Assistant

  • In Windows, search for HP Support Assistant and open the application.
  • Select the My Devices tab, then select your PC from the list of devices.
  • Go to the Troubleshoot and Errors tab, then select Battery Check.

How to check if the battery is working on a laptop?

Look at the condition of the contacts on the battery and on the laptop itself. if they are damaged. The battery itself should be flat. if there is swelling, it should be replaced immediately. Such a battery is no longer usable. If the battery is non-removable, swelling can be identified by the case of the “laptop” itself.

Why Lenovo laptop won’t charge?

If your Lenovo laptop won’t charge from the mains, then it’s not always the battery. This could be a system error. To fix it, you need to remove the battery, restart your Lenovo IdeaPad, enter the BIOS and set the default settings. This problem can occur when you replace the battery with a new or non-original one.

Is it possible to keep the laptop on charge all the time?

Whether it is necessary to keep the laptop on charge constantly. not at all, if we are talking about Li-Ion, whether it is possible to keep a charged laptop on charging. undesirable if we are talking about Li-polymer. The lifespan of modern batteries depends on many factors.

Checking the power supply

The first step is to check all sections of the power supply between the outlet and the laptop, starting with the first. Then check the power filter from which the laptop is powered for operability, exclude damage to the power supply (by trying to turn on the computer with the battery removed) and make sure that it is correctly connected to the laptop. By eliminating the most obvious causes of the malfunction, you can assume the rest of the problems.

Why a connected HP laptop battery won’t charge and what to do about it?

Every laptop user will sooner or later face a battery malfunction. This breakdown is inevitable due to the nature of the battery. It has a limited number of charge and discharge cycles, therefore, in fact, it is a consumable.

That, however, does not exclude the possibility of failure of the actual battery components or other sections of the supply network. In addition to the end of the working life, incorrect charging can be caused by:

  • improper operation of the charge controller;
  • damage to system board elements;
  • software failure;
  • malfunctions in the section of the power supply between the outlet and the laptop.

Depending on the nature of the breakdown in a particular case, you should choose a suitable way to solve it. In case of low “health” of the battery or malfunctions of the charge controller, the best option is still a replacement. No special skills are required for replacement (except for models with a built-in battery). The main thing is to choose the right block. So that it is fully compatible with the laptop.

A special marking, which includes the designation of the laptop model and the part code, will help to purchase a known suitable model. However, the reason for the unstable operation is not always related to the problems of the battery itself. Consider other options.

Motherboard problems

The least favorable type of failure is damage (regardless of the cause) to the laptop motherboard. A lot of elements are responsible for the distribution of electricity in such a complex system. from millimeter resistors to fairly complex microcircuits, power controllers.

Connecting a known good battery with minimal wear will help to detect breakdowns. If, after manipulating the software and using a working battery, the symptoms persist, then most likely the matter is precisely in damage to the power circuits on the board.

It will not be possible to fix such a problem without special skills and tools. The only option is to contact an appropriate workshop for a professional repair. Wizards will carry out the necessary diagnostics and replace the failed component.

Software glitches

Incorrect battery operation can also be caused by software. There are two most common cases. third-party charge management software, failure of low-level settings or drivers.

The first is identified by a non-standard power supply icon in the operating system taskbar. A third-party program (Battery Mode, Battery Care, BATExpert and others like them) must be detected and removed from the Programs and Features menu, accessible through the Control Panel, which, in turn, is invoked through the Start menu.

Low-level software crashes are resolved as follows:

  • Turn off the laptop, unplug it and remove the battery.
  • Hold the power button for one minute.
  • Connect the network adapter, and turn on the laptop.
  • Before loading the operating system, press F10 (esc or F1, and then F10, depending on the laptop model) to open the BIOS.
  • Find the item Load Default Settings or Load optimized defaults and apply it. BIOS settings back to factory settings.
  • Exit and Save changes.
  • Turn off laptop.
  • Connect the battery and AC adapter, and turn on the laptop.

If the problem was in the wrong settings, then after these manipulations the charging process should work.

What to do?

In cases of difficulties with the battery after prolonged operation (more than 3 years), in 90% of cases, replacing the battery that does not work as a result of severe wear of the elements or a malfunction of the controller will help.

If the battery stops charging suddenly, for example, after updating or reinstalling the operating system, then it makes sense to check the software. In particular, download and install the current version of the chipset driver from the manufacturer’s official website.

And in situations where all the user’s actions do not bring tangible results, it remains only to contact the specialists. You should not neglect the possibility of warranty service (if its term has not expired).

Problem: Laptop battery is connected but does not fully charge

The problem is manifested 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 1. reset battery settings in BIOS

  • Disconnect the power supply. Unplug or unplug the AC adapter from the device.
  • Take out the battery. In models with a removable battery, and there are most of them, for this you just need 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, you do not need 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 replace the battery.
  • Insert the charging plug and turn on the power supply into the outlet.
  • We turn on the laptop in the usual way.

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

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 a 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 required level of charge is also solved by calibration.

Diagnostics of programs on a laptop

If the diagnostic utility shows no significant wear on the battery in step 1, then the battery is probably not the direct cause of the drop in battery life. The culprit of the fast discharge may be some program you recently installed that runs in the background and prevents the processor and Wi-Fi chip from going 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.

Method 3. if the power supply does not work

Another reason 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.

How To Fix HP Battery Not Detected / 0% Available Plugged In Not Charging / Battery Wont Charge

  • Turn off the laptop, unplug the power supply.
  • 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 enough current to operate the laptop and charge its battery at the same time. Such a device must be replaced.

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.

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 get started, we advise you to do the BIOS reset operation described above.

Battery replacement (if necessary)

If the wear is high, then it is likely that it is the reason for the 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 battery is not removable and it will be more difficult to replace it yourself. It is safer to do this at a service center.
