Laptop power supply does not work. The reasons
Let’s look at the situation when your laptop power supply (charger) does not work and what can be done to solve the problem.
Often, the problem can only be eliminated with the help of specialists of the service center and special equipment. We recommend that you seek professional help and not risk the performance of the laptop itself, which can be damaged as a result of unskilled repair of the charger.

A laptop for work does not need to connect to the network, but when the battery sits down, you can’t do without an electric outlet. Field breakdown of the power supply leads to the fact that users cannot charge the laptop battery, as a result of which it is impossible to use the laptop.
Reasons why the laptop power supply works
The charger may stop working for the following reasons:
- Charging burned/burned down (the smoke and smell appear, the visible melting of the case).
- Excessive heating and load.
- Mechanical damage to the cable or connector.
All these problems are corrected by the repair or replacement of the charging adapter. It’s easier, of course, to buy a new power supply, because the repair of the old will cost about the same amount.
The battery is not charged
Previously, a working battery may stop working if the computer is relatively new. If the battery is connected in the laptop, but does not charge, while the power supply is working, there are several solutions.
Option 1. system rebooting
Sometimes in the work of charging systems there are malfunctions. The easiest way to fix the problem is to restart the system.
- turn off computer;
- take out the battery;
- Set the start button for 30 seconds;
- install the battery back;
- Launch the system.
- disconnect the power supply from the computer;
- turn off the laptop;
- take out the battery;
- connect the power supply and start the computer;
- In the dispatcher, find the battery among the sections, delete the subparagraph “Battery with ACPI-compatible control” (similar name);
- Turn off the laptop, insert the battery and enable.
The listed manipulations are the simplest possible, they do not always help solve the issue, but they will not harm.
Option 2. Reset BIOS settings
It is not always possible to determine why the battery does not charge on a laptop of a particular company, but this solution is suitable for all models.
- It is necessary to disconnect the power supply;
- Get out the battery. In most cases, they are removable in order to take them out, it is necessary to move locking elements;
- Set the start button for a few minutes;
- return the power supply, the battery cannot be inserted back;
- When turning on the system, you need to clamp the button to go to the BIOS settings. For different models of computers, different combinations can be used. Often used F2, del or F12;
- It is necessary to reset the settings to the pre.installations (the column “Restore Defaults”.) and save the action;
- Close the start button to turn off the computer;
- Disconnect the power supply, insert the battery;
- attach the power supply and start the laptop.
Option 3. Delete utilities
In some laptops during production, utilities are installed, which monitor the charging of the device. They increase the duration of the battery, while interfering with full charge.
You can check the availability of utilities in the laptop notification (system tray). The charging icon can externally differ from the standard. this is a sign of the availability of a utility.
Modern systems independently regulate the process of using energy, so installing additional applications is not needed.
Option 4. The power supply is faulty
In the presence of mechanical damage to the block, the battery will also not be charged.
The computer should turn on, work from a network without a battery. If not, the power supply is faulty. Perhaps the wire broke or lacks power to charging.
No need to constantly connect the computer to the network. When the battery is 100%charged, it is necessary to periodically turn off the power supply unit. A simple action will help extend the battery life.
The battery is connected, but does not fully charge
There are situations when the battery charges less than 100%. Why is this happening? The productivity of the battery falls over time, the duration of the battery is reduced by 3-5 times. For example, ASER or ASUS models are designed for autonomous work for 4 hours, but the charge began to grab up to 30 minutes.
For laptops with the Windows 7 and 8 system, the Battle Care program has been developed. It doesn’t matter. the Lenovo or ASUS computer is used, it is available for all models. IOS devices can use Battle Health.
The level of performance of the battery is determined by 3 parameters:
- maximum power at the moment;
- the power laid during production (declared for the new battery);
- wear level as a percentage.
If the wear indicator is large, the device should be changed. If the battery is removable, there are no difficulties with a replacement. In small models they are built.in, it is difficult to get them on their own. You should contact a computer master.
Each battery has a service life, after its end, the battery quickly sits down or does not charge. A faulty battery can increase in size, pout and hurt the motherboard of a computer. If a slight deformation is noticeable, it should be changed.
The culprit is the battery
Modern mobile computers are equipped with batteries of lithium-ion or lithium-polymer type, because they are roomy (differ in high charge density), they are quickly charged, capable of giving large currents to the consumer devices without harm, have a low level of self-discharge and are inexpensively worth. However, the real service life of lithium nutrition elements is not too large-with normal use, it rarely exceeds 3-4 years. And signs of wear and tear appear even earlier-even 1.5-2 years after purchase.
How to find out that the battery is worn out and needs to be replaced
The natural aging of the battery makes itself felt by the following features:
- The battery life of the computer is noticeably reduced.
- The charge level indicator gives incorrect values. For example, the laptop has just been charged 100%, but after a few minutes it was discharged up to 0. Or the charge seems to be high, but the system asks to connect the power source, and if you do not connect it, the computer turns off.
- System monitoring utilities, such as AIDA64 and Hwinfo (in the screenshot below), show a high percentage of battery wear (parameter Battle Wear LEVEL).
The Wear Level indicator of the new battery is a unit of percent (it loses the capacity of storage a little). When 40-50% reached, the symptoms of aging are manifested “in all glory”. With wear on 75-90%, a mobile computer, as a rule, turns into a desktop and eats only from a socket.
Attempts to charge a strongly worn battery, especially with signs of bloating and with flows of electrolyte on the case, are not only useless, but also dangerous. they can lead to a fire and explosion of lithium!
Does it make sense to repair the laptop that has developed its resource? Most often not, since this is fraught with significant technical difficulties and a simple replacement of cans (nutrition elements) is not possible here. Yes, and such repairs are done, as a rule, more expensive than buying a new battery.
And if this is a malfunction?
The battery breakdown is manifested by the same symptoms as significant wear, but they develop not as it is aging, but at once. In addition, the laptop may generally stop working with a faulty battery: when it is installed, it does not turn on. However, most often the device simply ceases to see a faulty battery or refuses to charge it.
The breakdown of the battery is not always easy to distinguish from the failure of the charge system on the board. To differentiate these malfunctions at home helps to connect a similar deliberately serviceable battery. If the computer works fine with it, then the charge scheme is in order, and it is time to go to the garbage bucket with a broken battery.
It is as dangerous to charge and use faulty laptop batteries as very worn out.
How to choose a battery to replace a failed? Very simple: it is enough to know its Product ID. a unique identifier consisting of numbers and letters that manufacturers assign a specific model.
Product ID indicate the inner surface of the battery.
Laptop batteries of one lineup, as a rule, are interchangeable.
The redistent is serious
Lithium power sources are so arranged that when energy drops below the minimum threshold (3.3–2.7 V), they are blocked by the internal protection system. The reloaded battery cannot be charged. Alas, this condition is not always reversible. In some cases, the battery “revives” a long. many hours of connection to the current source or replacing the elements of the protection circuit with the hands of the repairmen. However, after such “resuscitation”, her capacity does not always return to the previous level, most often it remains reduced.
When reloading, the computer sometimes sees the battery and determines its level, but cannot charge. Neither during work, nor after turning off.
Fortunately, critical reloads of laptop batteries rarely happen, since the operating system carefully monitors this.
The battery supplied with a laptop is unconditionally compatible with the motherboard and the native adapter of food. What can not be said about the replacement purchased by her, especially leading the pedigree from the semi.basement factories of the Middle Kingdom. The reason is low quality, or even a fake at all.
In addition, incompatibility is found in cases where a well.fed battery was released much later or earlier than a laptop. The problem is the non.knowledge of the motherboard of the version of the internal controller of the battery. It happens that the issue manages to solve a computer’s BIOS update, but more often, unfortunately, there is no.
When the real battery capacity is below the passport
The battery capacity decreases over time. this is a natural phenomenon. However, in nature there are batteries with an initially low, but artificially overstated capacity, which is “drawn” by unscrupulous manufacturers and sellers. They either apply false information about the container on the battery housing, or sew it into its controller. The second way sometimes “rejuvenate” very old, almost developing their resource elements of food in order to sell them to an inexperienced buyer.
The first option for deception is easy to open using utilities to collect information about the system, for example, AIDA64 (in the screenshot below). The second. only indirectly. by calculating the time of full category from 100% to conditional zero.
An overestimated battery capacity makes itself felt too short for the autonomous operation of the laptop and often incorrect charge indication.
It’s all in calibration
The laptop battery is a rather complicated device that controls its own internal controller. It not only protects the nutrition elements from reloading and transforming, but also monitors the level of charge. Along with it, the charge level controls the scheme on the motherboard. Normally, the data of both controllers coincide, but after repeated charging and discharge cycles in the indicators, discrepancies appear. Because of this, the system begins to “think” that the battery capacity has decreased, and does not allow it to be charged completely.
Culprit. power supply
Laptop power adapters also wear out and over time begin to produce less current and voltage than initially. When there is very little current, it may not be enough to charge the battery. In addition, a reduction in power relative to the declared by the manufacturer is one of the symptoms of a power malfunction or their low quality.
The insufficient power of the power adapter makes itself felt by the following signs:
- Slowed down the computer, freezes when starting resource.intensive applications.
- Intensive heating of the adapter itself, up to the melting of the body and further complete failure from overheating;
- Protective shutdown of the adapter with increasing load intensity. At this time, the laptop goes into autonomous mode and the battery charging stops.
- Ending charging during the laptop and renewal after turning off.
To confirm or refute the version of the feed of the feeder, it is enough to power the device from a deliberately working adapter, for example, a universal one, which is compatible with it in terms of current and voltage.
Separate models of mobile computers, in particular, representatives of the HP, Dell and Lenovo brands, work only with original power supplies. When connecting a non.native adapter, they either do not turn on at all, or refuse to infect the battery. For example, Dell laptops inform the user about this with the following message:
Fortunately, not all manufacturers of mobile computer technology do this. Owners of ASUS, Acer, MSI and others are lucky in this regard, because finding an original power supply for replacing the failed system is not so easy.
The 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 operating time of the device from the battery is significantly reduced. For example, the laptop worked for 5 hours on one charging, and began to work for no more than 1 hour. We will analyze the three main actions that will identify and eliminate problems.
Action 1. Checking the status of a power source
So what to do if the laptop battery does not fully charge? It is important to correctly check the state of the battery. You can do this with a free Battle Care program.
If you have a laptop under the control of iOS, you can use a free Battle Health utility.
Having launched these programs, we select the three main parameters of the laptop battery for the analysis:
- Initial nominal battery capacity. This is precisely the power that the battery had before the start of use.
- The maximum charge is the power of the battery at the moment.
- Battery wear in percentage ratio. The higher this indicator, the greater the need to replace.
By checking the condition of the battery, as well as its current charge level, we can conclude about its wear and need to install a new power source.
Action 2. Battery replacement
Big wear of the battery can inform its owner that the laptop has reduced work time without charging, or therefore the laptop is not charged until the end. To solve this issue, you will need a new power source. If the removal of the battery on your laptop does not require special skills, then it will not be difficult to replace it on your own. However, non.removable batteries are installed in many ultrabooks, and replacement can be carried out only in the service center.
Action 3. Identification of energy.consuming programs
If critical deviations were not revealed when testing the battery, and the wear of the power source is small, then the reason that the battery on the laptop does not charge up to 100 may lie in another. For example, rapid discharge, incomplete charge or a sharp reduction in working time without a network, can signal that there are active programs on the device that do not allow to switch to the energy conservation mode. Such programs constantly load the processor and other modules, preventing the device from turning into a reduced energy consumption mode.
To test the programs launched on your device for increased energy consumption, go to the tasks manager, and evaluate how actively the background programs use the processor power.
If you see that some program constantly loads the processor, while not being important in the operation of a laptop or operating system, you can safely delete it. Removing such unnecessary background programs will significantly increase the battery life of your laptop.
The new laptop battery is not charged
Infecent, but very unpleasant situation when a new laptop battery is not charged. If we are talking about a new battery, then the first thing to do is visually evaluate the marking applied to it.
It should be identical to the one that is applied on the old battery.
Another probable reason that the new laptop battery is not charged is the wrong initialization of the battery. You can identify and solve this problem with your own hands by doing simple actions:
- Complete the device and disable power.
- Disconnect the battery.
- Forcibly turn off the device using a button and hold it for about 30-40 seconds.
- Install the battery back.
- Connect power and start the laptop.
After you have done all the manipulations, and the laptop is connected to the network, but does not charge, only one reason remains. production marriage. Here it will not be possible to solve the problems independently, it is necessary to contact the official representative office for guarantee replacement.
Overheating of the batteries
The answer to the question, “why the laptop is not charged” can lie inside the device itself. A large amount of dust is accumulated in a dense layer on the cooling radiator, as a result of which the laptop overheat.
The 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 shutdown of the battery charge can be the use of the device in dusty, impatient rooms, the high temperature of the room.
How to understand that the problem is in this? Initially, the laptop works like a clock, it is normally charged, but at one point a notification pops up that the battery does not charge. This is one of the main criteria that the device is overheating. There may also be another situation when the laptop battery 0, connected, charges. This suggests that it is time for the device to make prevention and clean radiators from dust deposits.
Also, in order to reduce the degree of heating and avoid situations where the laptop battery does not charge, you can use special stands.
They allow you to cool the device, which means reduce the load on the processor and battery. Another important advice: you should not put a laptop on soft surfaces like a sofa or bed, as they block the ventilation holes.
Problems with drivers and chipset
The battery may not consume a charge due to problems with the operating system and its updates. For example, yesterday, the battery was charged as usual, and today the laptop does not respond to charging, and the system has not happened. Try to take a few steps described below:
Another option is that the laptop is not charged due to reinstalling the operating system or installing large updates. In this case, the device may not have enough drivers to correctly determine the battery. To eliminate this problem, you need to download and install drivers that control power.
A few more tips
Here are a few more subtleties that can answer the question of what to do if the battery is not charged on the laptop:
- Some devices are equipped with the Battle Life Cycle Extension function, the task of which is to specifically reduce the percentage of battery charge in order to increase the number of charging cycles. If the charging is connected, the laptop does not charge after a certain mark, then this function is most likely to blame. It can be easily disconnected in BIOS by going into the Advanced tab. It should be remembered that different models can have different names of this function.
- In the 10th version of the Windows operating system, a message in the lower part of the screen that the charge does not occur, it may appear if you turned off the laptop adapter with a completely charged battery, and after a few minutes you again connected charging. There is no breakdown, and after a while the battery will begin to charge, and the notice will disappear.
If you have stopped charging a laptop, try one or more points listed above. It is likely that you will get a positive result without visiting the service center and additional costs.
It is important to say that the battery, especially if it is new, is quite rare, except if it was not subject to mechanical effects. In 9 cases out of 10, the absence of a battery battery charge is due to programs of a programmatic nature, or breakdowns in the adapter or its connectors.
If the adapter of your laptop is equipped with a light indicator, look carefully if it works when turned on in the outlet. If the light does not give signals, it is obvious that the problem should be sought exactly there. Contacts on charging or laptop can also be oxidized or unusable. All these problems can be diagnosed with visual examination of devices.
Check all possible options, make tests and diagnostics of the battery, and only after that make a decision to buy a new power source for your laptop. It is likely that your battery will serve you for many more hours.
Why is the battery not charged on a laptop
So your laptop works, but does not charge, although it is definitely connected to the network. Among the possible perpetrators of the problem:
- Connector. Over time, the charging connector could be shattered, and contacts on the charging device were oxidized. Poor contact leads to a lack of power supply.
- Cable. One inconspicuous damage to the cable itself and charging will also stop working.
- Power Supply. The main element of the charger is the power supply, it can also fail.
- Driver. Perhaps this will be a discovery for someone, but for the normal operation of the laptop battery, an appropriate driver is needed. He may begin to work incorrectly, and then it will be required to reinstate.
- BIOS. The power supply of the device is adjusted through BIOS, so the changed settings can cause improper charging or its absence.
- Battery. Actually, the battery itself can come out of order, which is not so rare, especially if your laptop is already an old man.
- Other reasons. Sometimes the problem is not at all related to the laptop and its components. For example, she is in a faulty network filter or outlet where you connected a laptop.
The laptop battery does not charge: what to do?
What to figure out where exactly the malfunction lies, we will conduct a small diagnosis. One by one, excluding all possible options for the problem, starting with the simplest.
Dell laptop not charging “plugged in not charging” problem Solved
The instruction is relevant for all laptop models, if you have HP, ASUS, LENOVO, Dell, Acer or any other brand.
First, check the network filter or outlet. in general, the place where you connect the charging. Following. the contacts of the connector, you need to move it and make sure that everything is connected tightly, there are no traces of oxidation and nothing dangles. The power supply is regular, and the plug comes correctly? Move on.
Now you need to check the cord with the power supply. There may not be visual damage to them, but on some power supplies there is an LED indicator on which you can navigate. The bulb is burning. probably the block is working, no. it is definitely not all right with it. To completely exclude the problem of the PSU, it is best to borrow charging from friends or go to visit someone with a laptop. If the other cable also does not go charging on the laptop, then the problem is inside.
Time to verify the normal contact of the battery itself. Turn off the device, turn it off from the network and pull out the battery (if the battery is not removable, just unscrew the back cover and check it visually). Carefully inspect the contacts. If they oxidized or clogged with dirt, then carefully clean them with a wool with alcohol, and then insert the battery back, making sure that she joined as it should. If this did not give results, then it remains to move on to software methods.
A small retreat. If the laptop battery is connected, but does not charge to the end (although the process is going on), it may be in overheating of the worn.out battery. Typically, charging does not work as it should be when the laptop is turned on, and picks up everything 100% in the off state. Your case? Then the battery is replaced.
Let’s see if your battery is displayed in the operating system in general. For this, you need to go to the “Device Manager”:
If the battery is not displayed there, then it is faulty or connected incorrectly. If it is displayed, then you need to try to reinstall the driver:
- Click with the right mouse button according to the name of the battery in the “Device Manager”.
- Choose the item “Update the driver” and follow the simple instructions of the installer.
Then it remains only to climb into BIOS, in old versions, power problems are not excluded. We will not describe in detail how to go to BIOS. google instructions specifically for your model, we simply note that it needs to be dropped to factory settings. In the absence of changes, it remains to update the BIOS to the latest version, downloading it on the site of the manufacturer of your laptop.
If you read to this place, and not one of the proposed actions brought the desired result, most likely, the battery simply failed. It makes no sense to messing with, it is better to immediately contact a proven service center and, if necessary, replace the battery with a new.
Systemic settings for energy saving (using energy saving settings on a Mac computer). The slope of the settings allows you to choose an inaction time, after which it plunges into sleep. If the interval is too short, it may affect the battery work. As in the case of Windows, to solve the problem described, roll back the power settings to the factory installations.
Try to restart the controller of the SMC system controller. For laptops with removable batteries: turn off the power, remove the battery, press the power button for five seconds. Insert the battery, connect the power and turn on the laptop.
For new Apple computers with non.removable batteries: turn off the computer and leave the power adapter connected. Press and hold the power button, while pressing the Shift-Control-Option keys on the left side of the keyboard. At the same time release the keys and the power button, and then try to turn on the laptop.
Why is the battery not charged on a laptop? What to do if the battery on the laptop does not charge?
Undoubtedly, almost every laptop owner faced a problem when the battery of the device does not charge, since this is a fairly common phenomenon sooner or later, but it happens with any laptop battery. How soon this situation will come. depends on the frequency of using the laptop, and in particular the battery itself in autonomous mode. So, let’s look at: what to do if the battery on the laptop does not charge.
First of all, determine: is it really about the battery. If the laptop turns on and works, but the battery does not charge, then the matter is most likely in the battery. If the laptop does not turn on at all when the power is turned on, then the matter is most likely in power or power supply.
Why is the laptop battery not charged?
The problem may not be in the battery
Despite the fact that all batteries have their own service life, the situation when the battery does not charge. it does not mean that it came to the “end”. If the laptop does not turn on at all, then first check whether the charger connector is correctly inserted into the nest for charging a laptop. Then check the power connector connected from the outlet to the power supply. If everything is fine, then check the performance of the outlet itself, perhaps it does not work. In the event that everything is connected correctly and the outlet works. the situation is worse.
In this situation, the problem may not be in the battery, but in the charger (rectangular box), that is, in the power supply. The power supply could burn out and the reason for this could become technical wear or voltage difference in the mains. If you have a power supply from another laptop, and its output power is equal to the output power of the “native”, then you can use it in order to check the operability of the laptop and batteries. If you do not have such a power supply, then the cause of the malfunction will help in the service center.
In addition, if there is such an opportunity. check the power supply unit for working capacity if you have another laptop that feeds on the power supply of the same outgoing power. If the power supply works on the second laptop, then it means it is a working one, and the problem lies in the first laptop or in its battery.
In practice, Masterservis24 experts.RU there were cases when the reason for not charging the battery and the laptop did not work in the nutrition of the laptop itself, so it did not take power from the network and did not charge the battery.
In any case, if all the recommendations described above did not give a result, then contact the service center, to those specialists you trust.
The laptop battery is connected, but does not charge
First of all, use special utilities that control and analyze the condition of the battery. They will help you figure out the current situation.
When the laptop works from the network, but in autonomous mode. no (that is, the battery does not charge), it is possible that the matter is in contacts or an incorrectly inserted battery. Try to pull out and re.insert the battery into your laptop. Pay attention to the contacts so that they are not oxidized and, if necessary, clean them.
The reason that the battery has stopped charging on a laptop may also be due to a breakdown of the power board, that is, when the power is spent on the laptop, but there is no to the battery.
The battery on the laptop does not fully charge
If the battery on the laptop is not charged to the end, from the very moment of its purchase, then, most likely, this option is established by the manufacturer of the laptop (in order to extend its service life). With constant underdated the battery, it retains its capacity much longer than those that are fully charged.
The situation when the battery was charged earlier up to 100%, but now not, there is also a place to be. In this case, the battery can try to pump. To do this, discharge the battery completely so that the laptop turns off. Then connect the charger and put the battery for charging for 9 hours. If this procedure did not help, then it is possible that the control level of the battery has lost, it can be adjusted with special utilities.
If your laptop is under warranty, then go to the service center, where you should repair the device under warranty. When the warranty period is exhausted, select the authorized service center of your laptop manufacturer. This is about the power breakdown inside the laptop.
If a battery or charger has come out of the system, then they, for your laptop, can be ordered on the Internet. But if many can afford to purchase a new charger, then not each of us s to buy a new battery. Some services repair the battery by replacing old batteries with new. It is much cheaper than buying a new battery. At the same time, do not try to open the battery and replace the batteries in it yourself. Even if you do everything right, you need to reset the settings and calibration, the so.called battery firmware, otherwise the batteries simply will not function. That is why we still recommend that you contact specialists to replace the batteries of the laptop.
BIOS entrance for different laptops
For all computers and laptops, the entrance to the BIOS is approximately the same. Until loading the operating system, you need to press the key to go to the settings.
On earlier versions of Windows there are instructions right during the boot. On the black screen in white letters it is written which key to press to enter Setup (BIOS). This is usually DEL, F9, F11.
If there is no such menu, then you need to press during the show on the manufacturer’s screen. If none of the options are suitable, then the additional keys for some laptko models:
Когда ноутбук старый, а зарядка новая, измения в Биосе могут не помочь. Perhaps it is worth installing a new BIOS. To do this, find your device on the manufacturer’s website and download the necessary settings. After that, do everything as it is written above.
ACPI drivers and chipset
When it stopped charging suddenly. A problem was most likely due to the control program. Check and correct this:
- We go to the “Start” menu
- We open the section “Device dispatcher”
- Click on “batteries”
- There we are looking for a utility with the name “Battery with API with compatible Microsoft Management”. (Something similar is possible, there will certainly be the words “battery” and “API”), if this is not there, a problem is possible in the contacts of the laptop or incorrect operation of the operating system
- Click on the name of the program and click delete
- Reload the device through the laptop shutdown menu.
The updated laptop should start working as usual.
If such a program is not in the list in the “battery” section and the reboot did not help. Contact in support on the site of the manufacturer of your device. Perhaps you will help download additional utilities or updating the device.
How to check the laptop for wear in the absence of charging
Old batteries often do not show complete charging or do not charge at all. This happens with the depletion of the charging/discharge resource, the improper operation of the laptop, which led to the loss of battery capacity.
The reason is the wear of the battery, so you have to check the condition of the element, do it this way:
- Start the laptop into the work. Open the command line (under the start button).
- Prescribed in an empty PowerCFG Energy field. Then press the Enter button.
- They expect a response and watch a detailed report.
The report check the calculated capacity of the batteries, track the time of the last full charge. If the difference between the indicators is large, this indicates a high degree of battery wear, the element will have to be replaced. The procedure is performed in the service, it is inexpensive, but it all depends on the laptop model and the presence of components.
Go with the device to the service center. First, check the presence and compatibility of batteries, charging cord, laptop performance. Sometimes it happens that the problem is not in charging, but in the failures of the OS, the absence of the necessary software, etc.
Repair or buy
Wear of the elements, cord malfunctions, outdated battery, oxidation of contacts. the reasons for the lack of charging in the laptop. And the user has two solutions to the problem. replace damaged parts or buy a new model. It all depends on the type of breakdown.
The acquisition of a laptop is justified in the following cases:
- damage affected internal details that were not subject to restoration;
- There are no new consumables in the warehouse or service. they are no longer released;
- The laptop is morally outdated, not suitable for the completion of the tasks;
- There were defects incompatible with the normal operation of the device (lid breakdown, oxidation of all contacts, etc.).
HP Laptop Starts but No Display | Black Screen | @HPSupport
And, of course, if the repair costs more than the purchase of a new laptop with normal characteristics, the recovery of the computer completely loses its relevance.
To make sure the need for purchases, they turn not in one, but several centers. The fact is that the services work independently (especially for the repair of old models) and the masters do not always know about the possibilities of other specialists. Therefore, if in one center they say that there is nothing to fix, in another it may well be responded with consent and take the device for repair.
The second point is the replacement of components. The battery repair at its cost is comparable to the purchase and installation of a new element. over, a new detail will last longer restored, which means that the choice becomes obvious. The same thing happens if the client needs to replace the charging wire, clean the device from dust, etc.D.
And a few more tips to the owners of laptops who are faced with the lack of charging:
- Check the correctness of the organization of the workplace. If the laptop is constantly in the sun, it stands close to heating appliances, the battery will worry much faster.
