Chain failure and oxidation
Also, the reason may be hidden in the motherboard and power supply. Electrical circuits and circuits can be out of order, which is why a computer connected to the network stops charging. A more serious case is the oxidation of the battery contacts. This in turn leads to poor contact with the motherboard. If this kind of problem occurs, the inoperative equipment will have to be replaced or cleaned.
Reason in utility?
If the battery is connected, but not charging in the laptop (asus, samsung, etc.), the reason may be in the Special utilities, “factory”. Such utilities are focused on preserving the longevity of the battery, and can suddenly become an obstacle, the equipment stops fully charging.
Searching for SIMilar utilities can help solve the problem. To start the search, you need to go to the Task Manager (CtrlAltDelete). The window that opens will provide the user with a list of currently running programs. If the reason is in the utility, the battery icon on the screen will differ from the standard one. In the “Uninstall software” tab you can find a program with the same icon and uninstall it.
What if the battery is connected, charging, but 0% charge is available, or it does not charge to 100%? This naturally reduces the duration of the laptop, and very significantly. What can help the user in this case?
First you need to check the performance and general “well-being” of the battery. This can be done using the Battery Care utility. We pay attention to such important parameters: power (nominal, maximum) and wear of the laptop battery. The ratio of THESE parameters and the value of the latter will inform the user about the true state of the battery. If the wear is critically high, then most likely this is the reason that the laptop has stopped charging.
How to get rid of annoying calls from unknown numbers: say goodbye forever without regret
When the battery is connected but not charging on the laptop, many users immediately seek help from service centers. The latter, in turn, take quite a lot of money for their repair services, or even offer to replace the old battery with a new one.
However, what if the PSU is NOT old at all? Is it really impossible to do without financial costs? Can! In this article, we will consider the most common causes of this problem and effective ways to solve it.
Replacement is indispensable?
If your HP laptop has a battery connected, but does not charge (as in second-party laptops), you can solve the problem yourself. You can also determine that the device needs to be replaced. This is a prerequisite in the event that the power supply (or plug, cable) has lost its functionality. How can I check this? So, we observe the sequence:
1. Turn off the laptop. Removing the power supply from the mains.
2. We take out the battery. Connect the plug immediately. 3. Next, the PSU needs to be connected to electricity.
4. Including laptop.
If the laptop is NOT turned on again, the problem is obvious. “Charging” has become unusable.
Why is the phone battery connected but not charging?
If the battery is connected, but not charging, then it may have sat down to zero and the traditional way is NOT to charge it, although the phone will see the charger.
You can solve the problem with a toad (if the battery is removable). Throw up to 6 volts on it. on the extreme contacts. plus to plus minus to minus.
So hold for about five minutes, then insert the battery and Connect the charger. if it does not help, then it may be that the battery itself is NOT serviceable.
Why the phone won’t charge the battery
One of the most common “defects” that you may encounter when using your phone is when the unit won’t charge.
In this case, it is very important to correctly determine the cause of this phenomenon. The first steps you should take when you see that your phone or tablet battery is not charging is to check the outlet.
Next, make sure that the charger is fully functional. It must match your device (people have several gadgets lately and may inadvertently use a charger that is not suitable for their phone).
Also check the operation of the cable and plug. Examine the connector on the phone. There may be several circumstances when the unit does not charge.
What to do about it, you can only decide if you know the exact reason. The reasons may be different.
The charger may not be working. In the case of the introduction of Chinese-made equipment, this happens often. in this case, it will need to be replaced.
It is still a common thing when poor contact between the plug and the input, and sometimes with dirty contacts in the connector.
It is recommended to remove the battery and wipe the contacts, but do not use solvents. Also, quite often the connector needs to be replaced with a new one.
The phone battery is NOT charging. it may have already served its purpose. each is designed for a certain number of charges. The solution is to install a new battery.
There may be damage to the built-in electronics: mechanical damage or moisture ingress. This phenomenon is often accompanied by battery swelling. The solution is to replace with a new one.
It happens that the controller is damaged in the phone or tablet. He is responsible for the battery charging process.
There may be an option when the device sees the charger, but does not charge. In order to carry out repairs, you need to disassemble the phone and replace the controller. This process can only be achieved if you have the necessary skills.
Why my phone won’t charge a new battery
It is possible that you purchased a battery with a factory defect. What to do? Go to the place of purchase and change.
It is also NOT excluded that a deep discharge has appeared in the battery, especially if it is a tablet. The fact is that when discharging below the threshold, the phone sees it, but does not charge.
Then you need to connect the charger bypassing the controller and with a slightly higher voltage than in the native.
ATTENTION: in a new battery, the contacts can be covered with an almost invisible transparent film, and for some reason the sellers do not warn buyers
Why the phone does not fully charge the battery. 100%
The battery can be fully charged, but the charge level in the phone itself is displayed incorrectly or the battery has reached 20%.
Also, if the battery is not fully charged, 100%, then the defect may be in the charger. a small output voltage and of course a defect in the battery itself.
To check on Android, you can dial the code in Dialers. ##. Then the diagnostic utility will start. See what the charge current is when charging is connected.
ATTENTION: ideal charge is up to 80%, and discharge up to 20-40%. Take this into account, then your battery will live much longer.
Battery charging problems in Samsung or Lenovo phone
Samsung or Lenovo NOT charging when plugged into a wall outlet? These messages appear when there is no original charger
The problem could also be a damaged USB charging cable or inside the device.
If these solutions DO NOT work, there may be a software bug. In this case, back up your data and restore your phone to factory settings.
If we exclude mechanical destruction of the mini-USB port or charger, then there are several more reasons.
Disconnect the device from the charger, and then remove the battery. Within a minute, press the on / off button on the phone.
After that, put the battery back and try to charge the phone for at least 20 minutes.
If this does not help, the problem is either the battery (swap) or hardware. I also recommend looking. Success.
Laptop battery is connected but not fully charged
Users worry why the laptop battery does NOT fully charge when it used to be 100%. In this case, the device can be pumped. Actions:
- Discharge the battery until the laptop is completely turned off;
- Charge (9 hours).
If the bleeding procedure does not help, the only solution is to replace the battery. It is sometimes very expensive to buy a battery, then the services will offer replacement of batteries.
Trust this work to a specialist: independent intervention may not give results. Please note that after replacement requires a reset, calibration.
Charging may have stopped working for various reasons, you can do something yourself, but it is better to contact the socialists.
Laptop does not run on battery
In this material, in detail about the possible reasons that the battery is NOT charging on the laptop and in possible ways to fix it, the normal process of charging the laptop returned.
Note: before starting any action, especially if you have just encountered a problem, make sure the laptop power supply is connected to both the laptop itself and the mains (outlet).
If the connection is made through a surge protector, make sure it has not been disabled with the button. If your laptop power supply has several parts (usually there are) that can disconnect from each other. Unplug them and then reconnect tightly.
Well, just in case, pay attention to whether other electrical appliances powered by the network in the room work.
Why the laptop battery is not charging
The charger and battery are designed in such a way that over time, laptop owners have trouble charging their PC. The unit cannot charge and there is no charging indicator on the computer screen. This happens with very frequent use of the device on battery power and when working in sleep mode.
So, consider what needs to be done when the unit cannot turn on.
First you need to determine: is there really a malfunction in the laptop‘s power supply. To do this, turn on the laptop and see if it works or not.
If, when turned on from the mains, the laptop is working, but there is a battery, then the matter is in the battery.
The laptop cannot start at all, even when the power is on. the matter is in the electronics or in the power supply.
The battery is NOT charging on a new laptop (suitable as the first method for other scenarios)
If you have purchased a new laptop with a pre-installed licensed system and immediately found that It does not charge, this can be either a disadvantage (although the probability is not high) or an incorrect initialization of the battery. Try the following:
- Turn off your laptop.
- Disconnect the “charging” from the laptop.
- If the battery is removable. Disconnect it.
- Press and hold the power button on the laptop for 15-20 seconds.
- If the battery was removed, reinstall it.
- Connect the laptop power supply.
- Turn on your laptop.
Helpful The described steps are not often, but they are safe, easy to perform and a lot of time will be saved if the problem is solved right away.
Note: there are two more variations of this method.
- Only in the case of a removable battery. disconnect charging, remove the battery, hold down the power button for 60 seconds. Connect the battery first, then the charger and do not turn on the laptop for 15 minutes. Enable after that.
- The laptop is turned on, charging is turned off, the unit is not removed, the power button is pressed and held until it turns off completely with a click (sometimes it can be absent) for about 60 seconds, connect the charging, wait 15 minutes, turn on the laptop.
What to do if the laptop battery does not work
Buyers choose laptops because of their portability and the ability to run for extended periods of time without having to connect to a power source.
During autonomous operation, the device consumes the energy stored in the battery. Over time, the battery loses its capacity, but this should not happen earlier than after several hundred charge / discharge cycles.
In order for the battery to last as long as possible, it must be calibrated from time to time.
However, in addition to the problem with the fast discharge of the laptop battery, the user may also face a malfunction when the battery refuses to charge or does not fully charge. These problems can arise for a number of reasons, and below we will consider what to do in such situations.
Old unit does not charge or does NOT fully charge
When a battery that has been in use for a long time is NOT charging, it is possible that the problem is in itself. The battery controller could be broken or the capacity is running out.
The battery loses capacity after a large number of charge / recharge cycles. It turns out that the battery is quickly discharged and is NOT fully charged. Its real capacity is much less than the declared value at the time of manufacture. You can find out the real battery capacity and the degree of deterioration using the AIDA 64 utility.
Attention should be paid to the parameter “Current capacity”. Ideal if it matches the stated battery capacity. As the operation progresses (approximately 5-10% per year), the actual capacity value will decrease. It directly depends on the quality of the battery and the operation of the laptop.
When the indicator of the real battery capacity becomes less than the declared one by 30% or more, it is recommended to replace the battery with a new one.
Software from the laptop manufacturer
Laptop manufacturers produce special programs to monitor the condition of the product’s battery. In some cases, these utilities start to perform battery optimization.
For example, some Lenovo laptop models have a dedicated battery manager. Various modes have been added to it, among which the following stand out:
- Better battery life.
- Optimal battery life.
In some situations, due to the first mode of operation, the battery stops charging. In this case, do the following:
- Switching the manager’s work mode and trying to charge the battery again.
- Disable this program and check. Sometimes you can’t do without removing this utility.
Before removing such software from the manufacturer, you should make a backup of the system. It is possible that this program affects the functioning of not only the battery, but also other components.
Laptop is NOT charging
Perhaps the battery is working properly and it is not at all about it.
Although batteries do have their own lifespan, there are situations where the battery cannot be charged and still remains functional. If the device does not turn on at all, then first you need to check:
- Is the charging connector installed in the port from the laptop?
- Check the connector that connects from the outlet to the power supply unit.
When the two steps have been taken, you can start diagnosing the network (outlet). It is quite possible that it is not working. If you find out that the network is working properly, the problem lies elsewhere.
Most often, a power supply unit (rectangular box), that is, charging, may be related to a malfunction. The unit could have burned out from the inside, which means that technical wear or voltage drops occurred.
To check the operation of the computer and the battery, you can use the power supply from a second laptop. But before implementation, you need to check its output power. it should be the same as in the faulty one. If there is no spare power supply, then the service center will help to establish the causes of the malfunctioning state.
Fixing d3dcompiler43 dll error
Start checking the power supply for functionality if there is a second laptop with the same element. So, you need to pull out its end and insert the block from the first computer to check for operability. If it works, then the problem is with the first PC or its power supply.
If the result is comments from the above actions, then it is important to contact the service center. But, if the problem is in the laptop, then you can try to manipulate it.
Battery is connected, not charging (or Charging fails in Windows 10)
Perhaps the most common variant of the problem. in the status in the Windows notification area, you see a message about the battery charge, and in parentheses. “connected, not charging.” In Windows 10, the message looks like “Charging not in progress.” This usually indicates software problems with a laptop, but not always.
Charging modern lithium-ion cells requires a special power mode, which is actually provided by a special control board. If the battery has changed during operation, especially from third-party manufacturers, and then there are problems with its implementation, the problems may be at the level of this component.
The most common ones are:
- Incompatibility with laptop. Even suitable second-hand batteries may have some electronic components that differ in characteristics and parameters;
- A number of technology suppliers are especially careful to eliminate the use of counterfeits and build protection against them even at the level of autonomous power sources. Counterfeit components SIMply won’t function on such a computer;
- Reverse polarity on the board due to defective or counterfeit products. It is recommended to be extremely careful when using components from little-known suppliers, as the quality of their workmanship may be poor.
You can find out why the failure occurred, as well as check its health, using the same testing utilities or SEPARATE programs, which analyzes its indicators in more depth.
The reason why the charging process is not taking place may be due to the operating system’s power driver. You can fix this problem by reinstalling the driver or disabling it.
If the operating system used is Windows, then all the necessary settings are located in the appropriate section “Control Panel”.
- Go to the “System” menu;
- Select “Device Manager”;
- Then select the “Batteries” tab;
- One or more Microsoft ACPI Compliant Batteries will be listed. select Required;
- In the tab with the properties of this component, you should find information about the driver and reinstall it.
After THESE actions, you can try to change the power supply mode by standard means of the operating system and restart the computer.
Charges but not fully
A situation when the battery is not fully charged may indicate such problems:
- Physical wear and tear of chemical elements;
- Controller failure;
- Actions of third-party utilities and managers.
In the first case, you can use the above-mentioned software methods for determining and diagnosing all fundamental characteristics. Based on the results obtained, you can determine their condition and the need for replacement.
Incorrect operation of the controller can also be determined using Special programs or standard methods of Some operating systems.
In the latter version, the problem may be that special utilities are running in the background, which control the power supply of the laptop and the charging process.
As practice shows, sometimes hardware manufacturers or third-party developers offer software designed to adjust the parameters of a mobile PC’s power supply. Such utilities automatically change the charging process, as well as optimize the consumption and use of hardware power.
What browsers are there for the computer? details here.
By disabling third-party utilities for managing PC resources, you can correctly display the battery status and charge it up to 100 percent.
If this does not happen, you need to do the following steps:
- Turn off the power;
- Disconnect the charger and remove the battery, if possible;
- Hold the power button for up to 30 seconds
- Insert the battery without connecting the charger;
- Turn on the PC and check the power indicators.
In the same way, you can repeat this set of steps, but turn on the PC without autonomous batteries and connected to the network. As a result of the actions taken, the residual voltage of all capacitors without exception on the board will disappear.
It is recommended that the installed software or the built-in power manager be switched to optimal power supply mode. Use Economy or Best Performance modes should be disabled.
What to do, the battery on the laptop has stopped charging
The main advantage of laptops over stationary PCs is their high mobility and the ability to function independently. It can be provided by capacious and efficient current sources, on the parameters of which the duration of the laptop depends.
The laptop battery also contains dedicated controllers. Very often you can encounter a situation when, on a perfectly working device, it suddenly begins to behave strangely. its charge rapidly drops even with rather economical use, or the laptop battery does not fully charge.
Most of these situations can be associated with an incorrect charging process or failure of components of the laptop’s electrical circuit.
Find out the wear of the battery
Plugged in but not charging
The most common problem with laptop battery life is that it is connected to the network, functions properly, but no charge occurs. This indicates that the electrical circuit of the laptop and the charger is working, at least in terms of supplying electricity to one PC, but there is a problem with the controller. There may be several reasons why the battery is connected but not charging.
The laptop battery pack contains, as a rule, several elements. here are 3 to 12 pieces. If one of them turned out to be defective or failed prematurely, then it is likely that the entire electrical circuit has been disrupted and it needs to be replaced. With a sufficient level of knowledge, this procedure can be done independently, having correctly selected the necessary elements according to the parameters.
Do NOT neglect the need to regularly check the physical condition of the contacts. Over time, they could oxidize or clog, which leads to poor surface contact and malfunctions.
In this case, it is necessary to wipe all contacts with an office eraser.This procedure must be done carefully, in order to avoid damage to the contacts themselves and elements located in the neighborhood.
The battery is NOT charging
Typical battery problems
As you know, over time, the characteristics of chemical sources of current fall, and this process is irreversible. One of the fundamental characteristics is the number of recharge cycles, in modern laptops it is about 700 times. This means that if the laptop is connected to the mains every day, then it will function properly for at least about two years.
If the laptop has been used for a long time, it is likely that its batteries may gradually fail and can no longer provide sufficient charge.
Help to determine whether specialized software can do this. Most manufacturers of equipment, in particular portable PCs and laptops, release special utilities for testing the state of power sources.
As a rule, they provide detailed information, including the following parameters:
- Working capacity;
- Charge level and others.
In addition to changing the characteristics of chemical elements, the problem can also lie in controller failures. It is usually found on a special board inside the battery pack, or less often built into the motherboard of the laptop itself. Specialized software utilities from the manufacturer or third-party developers will help you to check it.
