Fully charged 100 recommended to replace the battery. What does "It is recommended to replace the battery on a laptop" mean: how to correctly fix battery problems

In Windows 7, a system for monitoring the battery, for its wear, has appeared - if it has reached unacceptable values, the operating system can report this. Very often this message appears on those laptops that are about 2 years old or more, and their batteries have lost capacity due to natural reasons. But, nevertheless, in some cases this message appears with a new battery.

To get rid of this warning, try the following:
- Carry out several cycles of full charging, as well as discharging the laptop (right before turning it off). At the same time, charge the laptop with it turned off.

If this does not help, do the following to resolve the recommended battery replacement on your laptop:

1. Open the Device Manager on the laptop (Start button - then Control Panel - then select System and its maintenance - then Device Manager);
2. Select the Battery section, namely Microsoft ACPI-Compliant Control Method Battery, right-click, then select Delete;
3. Restart your computer. The driver will be reinstalled.
If this method does not help, then do this:
1. Open Device Manager on your computer;
2. Select the Battery section there, right-click, and then select Disable.

However, if the battery still holds a charge much worse, if earlier you could use the computer offline for about 2 hours, and now the battery usage time barely reaches thirty minutes, and the system displays already familiar messages, something should be done.

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

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

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

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

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

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

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

Checking laptop battery status

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

The utility can only be used with an administrator account.

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

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

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

Operating system failure

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

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

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

Reinstalling the battery driver

The driver can be uninstalled through the "Device Manager" - a built-in Windows utility that shows information about all the components of the computer.

Battery calibration

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

Some BIOS versions "can" calibrate the battery automatically

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

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

The easiest way is not to boot Windows, but to wait for the laptop to discharge by turning on the BIOS. But this takes a lot of time, and in the process you will not be able to use the system, so it is better to change the power settings in Windows itself.
To do this, you need to go along the path "Start - Control Panel - Power Options - Create a power plan". Thus, we will create a new power plan, working in which the laptop will not go into sleep mode.
To create a new power plan, you need to click on the corresponding menu item
During the setup process of the plan, you need to set it to "High performance" so that the laptop runs out of power faster.
To drain your laptop faster, choose a plan with high performance
You also need to prohibit putting the laptop into sleep mode and turning off the display. Now the computer will not "fall asleep" and will be able to shut down normally after "zeroing" the battery.
To prevent the laptop from going to sleep and ruining the calibration, you need to disable this feature.

Other battery errors

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

Battery connected but not charging

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

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

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

Battery not detected

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

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

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

Laptop Battery Care

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

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

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

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

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

It happens that your PC in the lower right corner of the monitor began to show an alarming red cross. The system indicates what is on the laptop. What to do in this case? Is there a solution to the problem? Of course have. But it is worth noting that this system message is not always correct, and it does not need to be blindly trusted. Perhaps the problem lies elsewhere.

Causes of the problem

Luckily, there aren't many of them. The most logical version of the error is the natural wear and tear of the battery and its incorrect operation due to a long operating time. The operating system itself analyzes the health of the battery and indicates that it needs to be changed.

Wear is a certain number of discharge / charge cycles in which the battery loses its performance. By the way, this period is indicated in the instruction manual, and surprisingly, on average it is 2-3 years. Although, of course, it all depends on the correct use. Perhaps, and which has worked for 6-7 years, will work like clockwork.

Another reason is a system failure. It happens that the system takes a working battery for a faulty one, and therefore a similar error occurs. There is another factor due to which it is recommended to replace the battery on a laptop - these are problems with the outlet. This happens due to power surges or a malfunctioning outlet. How to solve this problem, you can guess for yourself, but let's take a closer look at the previous two.

Simple steps

Before delving into system changes and other complexities, try to get started:

Carry out several cycles of charging and discharging. In this case, the battery needs to be charged only when the laptop is turned off.
Also try removing the battery and leaving it alone for 10-15 minutes. Then insert and turn on the laptop.
Accept and use the laptop as a desktop PC. In this case, no cost.
Buy a new battery. There may be problems finding the right model.
You can take the battery in for repair. This option is not the best, because not always financial costs can justify themselves.

Update drivers

So, we examined why the laptop writes: “It is recommended to replace the battery”, and now we will analyze in detail the ways to fix it. The first one is updating drivers. This option is best used if you are sure that the battery is really working. Press Win+R to open a command prompt and type control. Select "View" and "Large Icons". Select "Batteries" in Device Manager. From the proposed list, select "Battery with ACPI-compliant management" and right-click to delete this item. Now, for the changes to take effect, restart the PC. Once turned on, you won't see a "replace battery recommended" message on the laptop. What to do if it didn't help?

calibrate battery

To carry out this process, you need to understand what it is? If you do not delve into a lot of complexities and terms, let's move on to such a concept as the "memory effect". In a simple way, this is a decrease in the initial capacity. This happens either due to physical defects, or as a result of constant recharging of an incompletely discharged battery. Simply put, if your laptop is not completely discharged, you charge it, but again - not completely, it loses energy, but in the end does not get it.

The battery becomes weaker due to the fact that the battery seemed to “remember” the limit to which it could not charge, and perceives it as the limit of its capacity. Then a lot of errors appear, and the battery does not work correctly. The calibration process does not make the volume larger, it only removes all errors from memory and resumes the capacity boundary.

There are two types of battery:

lithium-ion;
nickel.

Each of them has its own calibration process. In the first case, the "memory effect" practically does not affect the battery. But wear and tear, like any technology, is bound to occur. Therefore, calibration in this case is carried out so that unexpected shutdowns do not occur at a 30% charge. If it is still recommended to replace the battery on a laptop, what to do in the case of a nickel battery?

They require periodic calibration. So, you need to work until you turn off completely. Then charge the battery to the maximum. It is advisable to repeat the process itself a couple of times. But before such a calibration, you need to set up a power plan. Find the "Power Options" tab in the control panel. You will be presented with several battery life plans. On different laptops, they are named differently. You need to select "Portable" or "Balanced". Next, click "Set up power mode" and in the lines "Turn off the display" and "Sleep mode", set the parameter "Never".

Disconnecting the battery

This method will not completely solve your problem if the laptop says: "It is recommended to replace the battery." What to do in this case? We do everything the same as in the case of updating drivers, only instead of "Delete" select "Disable". In this case, you will simply lose this annoying message.

How to check?

If the system writes: “It is recommended to replace the battery on the laptop”, then first you need to check the battery after all. "Start" - "Run", in the command line we prescribe powercfgenergy. A check will take place, and you can find the report in the "Additional Information" - "Battery Information" line. The larger the Last Full Charge value relative to the Estimated Capacity, the better.

How to replace?

Replacing an old battery is very easy. We turn off the laptop. There are two sliders on the back cover. One of them, when you move it away, returns to its place, the other remains in the desired position. Therefore, when we snapped off the second one, the first one needs to be held and the battery pulled out. To insert a new one, you just need to click it.

It's all Windows 7's fault

What does it mean - it is recommended to replace the battery on a laptop? Basically, you have already dealt with this issue. But sometimes it happens that the whole problem is in Windows 7. It turns out that this operating system is to blame for this problem. Despite the fact that Microsoft is trying to fix everything, OS users periodically complain about battery problems.

According to users, after buying a laptop with Windows7 already installed, after 2-3 weeks, the charge time and battery life are almost halved. So far, it is known that it is recommended to replace the battery on a laptop due to a mismatch between certain elements in the system itself and some BIOS elements, since in this case the battery requires constant recharging and wears out very quickly.

If you come across the fact that you are advised to replace the battery on your laptop, you already know what to do about it. If all the above methods did not help you, you will have to contact the professionals at the service center. Especially if the laptop is new and is still under warranty. Then the repair will cost you free.

Now asus laptop users can periodically, with bated breath, observe a message that

At the same time, its appearance is observed both on “hard workers” that have honestly worked for several years, and on recently purchased devices.

For most users, the appearance of such an unobtrusive recommendation becomes a fairly strong source of stress.

Usually, the monitoring function algorithm gives a similar maxim when the maximum value of the stored energy reaches 40% of the nominal value.

That is, if instead of the prescribed 4–5 hours, it holds a charge of only one hour or less.

The process of natural battery wear is inevitable, moreover, it is often exacerbated by improper operation.

The second reason is in the wilds of the system itself. Sometimes it happens that even owners of brand new laptops are perplexed, they see the mentioned message on their screen.

This is not a reason to panic, because the new battery would not physically have time to wear out to such a state. This is a system error, which is not difficult to eliminate.

How to fix the error?

And suddenly an unfortunate error occurs, what to do in this case? If there is a natural battery expiration, then there are few options. In fact, there are only three of them:

Look for positive aspects in using a laptop as a desktop computer.
Take a risk and give the battery for soldering to craftsmen.
Buy a new battery.

The first method is the most popular, apparently in favor of its outstanding cheapness.

One way or another, when the battery “dies” from wear and tear, you won’t help the cause without material injections or special knowledge.

Quite different with a software bug. It is not difficult to make small adjustments to the system settings.

In addition, eliminating the disturbing message will contribute to peace of mind. You can do this in several ways.

Option 1

For its implementation, you will need the "Device Manager". It opens from the "Control Panel", which is located in the "Start" menu.

In the open device manager, you will need the "Batteries" line. By clicking on it, a list of power sources used by the laptop will open.

Of the entire list, only the item “Battery with ACPI-compliant management” is needed.

Right-clicking on it will bring up a context menu.

From here there are two options.

First, you can disable this service (1). Then, after rebooting the system, the annoying message should disappear.

If this does not help, then you can completely remove it (2). Then, again after a reboot, the driver will be updated and the message will disappear.

If nothing has changed, you can take other methods.

Option 2

In this option, laptop battery calibration comes to the rescue.

In general, the calibration process is a sequence of 100% charge, full discharge and re-charge "to the eyeballs".

Such procedures will help the battery controller to set a more efficient flow rate.

Before starting the process, you will need to create a new energy plan. It will help speed up the process of discharging the battery.

First, you need to open the "Power Options" section in the "Control Panel".

In the power plan settings window, you will need to select the "Create a power plan" item.

The new plan will need to be named somehow. For convenience, the name "Battery Calibration" is used. After defining the name of the plan, you can press "Next".

In the plan settings window, you will need to select "Never" in all drop-down lists.

Thus, the laptop will not go into sleep mode and will not turn off the display during operation, which will allow you to drain the battery as much as possible.

After completing the parameter settings, all that remains is to click the "Create" button, and the new plan will be ready.

Now you need to activate it and wait until the battery charge decreases as much as possible.

The discharging process must be observed. Lithium-ion batteries deteriorate from being left in a fully discharged state for a long time.

Therefore, you must connect the charger immediately after turning off the laptop.

The battery must then be fully charged.

Advice! Correct operation will be a good help to preserve battery life. So, in everyday use, you should not allow the complete discharge of a lithium-ion battery. In addition, temperature extremes are sharply contraindicated for him. The normal operating range is between -10 C and +35 C.

Careful and proper handling is the key to a long battery life.

How to restore the battery in a laptop?

Laptop battery is draining quickly, but there is no money for a new one? We'll show you what to do!

In the taskbar of my laptop, a notification began to appear, an error was shown "It is recommended to replace the battery", although the laptop is relatively new and cannot be called old. What causes this error and how to deal with it?

With the release of Windows 7, a battery monitoring system was added - at the moment when it reaches low values, the operating system will be able to notify the user about this. Often this notice appears on laptops that have actually been used for about 2 years or more, and the battery has lost its capacity due to normal wear and tear. Despite this, in some moments such a notice was also noticed on new, freshly purchased batteries. If you want to avoid this warning, you can try the following:

Carry out one or two cycles of maximum charge and subsequent discharge of the laptop battery (discharging should be brought to a complete shutdown). Remember that you need to charge your laptop when it is turned off.

If this doesn't work for you, try the following method:
1. Go to the "Device Manager" on your laptop ("Start" then "Control Panel" then "System and Maintenance" then "Device Manager");
2. Open the "Battery - Microsoft ACPI-Compliant Control Method Battery" section, right-click and click "Delete";
3. Restart your computer. Your driver will be reinstalled. If this method did not fix the situation, there is one more option:
1. Go to "Device Manager"; 2. Select the "Battery - Microsoft ACPI-Compliant Control Method Battery" section, right-click and select "Disable".
