The tablet shows charging but does not charge what to do. What to do if a smartphone or tablet does not charge or does not turn on - blog about information technology: software, hardware, Internet, services, advice
The tablets and smartphones we are accustomed to work at the expense of the built-in batteries. Unfortunately, classic lithium-ion batteries are far from the safest and most durable. Like any battery, the battery in your tablet can fail. In this case, it will not be possible to charge it. This fact is not very pleasant and requires user intervention. However, there may be other reasons why the battery is behaving inadequately. There are a lot of reasons and they are all quite solvable. In this article we will try to figure out why your tablet is not charging and what needs to be done in such a situation. And at the end you will find a small guide to the correct "care" of the battery.
What to do if your tablet won't charge or turn on
If you turn to statistics, then the most popular appeal to services after broken displays will be a battery that has failed. Problems with the power controller and cables also fall into this category. All of them in one way or another affect the charging speed and its work in general. It often happens that the tablet does not charge at all. Faced with such a nuisance, you need to consider all possible reasons and based on them, make further decisions.
Checking the charger
Charger problems - the very first and most common reason a tablet won't charge is a malfunction charger... In most cases, one or more capacitors in the power supply case fail. You can test this theory with another charger or with a multimeter. To solve the problem, you can replace the power supply or repair it if you have the appropriate skills. Those who like to wield a soldering iron or those who attended a radio circle in childhood will surely cope with this task.
Faulty cable
A damaged cable is the second most common reason for not charging. A visual inspection is almost always sufficient to be sure of this. Tears, bends, exposed insulation: these factors can indicate "lethal" damage. Try to avoid jerking, jerking, bending, or throwing the cord. Users often save money and buy unofficial cables, which can also be a problem when charging the device. It is not worth solving the problem with repairs, it is better to replace the cable, especially since they are not so expensive.
Bad contact in connectors
Connector problems are another hardware problem that often plagues modern device owners and prevents the tablet from charging. There are two options. Either water or dirt has got into the connector, and then to restore functionality, you just need to thoroughly clean it. Or one of the contacts has burnt out and you need to contact the service center, where the charging port will be replaced with a new one.
Software crash
Software error - naturally, the "brains" of a mobile device can also fail and interfere with charging the gadget. Sometimes the tablet shows charging but won't charge. Sometimes it charges too slowly. There are many problems, but they are all solved by reinstalling the firmware. This is the first thing to do if you own an Android device.
Apple gadgets can also stop charging because you are using a cable that is not Apple certified. In this situation, before charging, the device must be completely turned off.
Battery failure
A faulty battery is a problem that overtakes anyone who has been using a tablet for a long time. The battery in your tablet is not permanent. Its capacity gradually decreases and soon the battery breaks down. This is one of the most common iPad issues. If it does not turn on or does not charge, it is possible that the battery has "died". Even more often, the battery fails when the gadget is physically damaged or when it is used in abnormal temperature conditions. The solution is always the same - to replace the battery at a service center. They do it very quickly and very inexpensively.
Failure of the tablet itself
Malfunctions of the device itself is another flaw that haunts all lovers of cheap power supplies and cables. If the tablet takes a long time to charge and its back panel overheats, then be sure the power controller is out of order. Another harbinger of this trouble is the shutdown of the tablet when it reaches 20-30% of the charge. To restore the normal operation of the device, a very complex repair is required, so think twice what is better, change the device or give it to the service.
How to properly charge your tablet and extend battery life
The problems described above can arise both as a result of normal use of the tablet, and in case of careless handling of the gadget. A lithium-ion battery is dependent on the constant circulation of energy in it. Any deviation from normal use can damage the battery. At first glance, it sounds difficult, but in reality you just need to develop a few correct habits and follow them when using mobile devices... The life of the battery, and with it the life of the gadget, can be extended if you follow a number of tips and tricks.
- Don't let the gadget go into deep discharge. The tablet battery must always be powered. The device must be fully charged and discharged at least once a month, otherwise the battery will quickly use up its resource and simply “die”. If you don't use your gadget regularly enough, then remember to give it a charge sometimes so that it continues to function normally.
- Do not overuse your charge. You do not need to constantly power the device from the mains. The tablet is not a computer, therefore, it cannot take energy directly from the network, but constantly recharges the battery, which significantly harms it. Experts recommend keeping the charge level between 20% and 80%. It is ideal for a lithium-ion battery.
- Do not use your tablet while it is plugged into a power outlet. This, of course, is very difficult, but it is better not to do this. Let the gadget charge quietly, and only then start working with it.
If the charge has not reached the maximum mark, and you urgently need to get to work or write to someone, then it is better to disconnect it from the network. This is also important if the tablet is 100% charged, before starting to work with the gadget, remove the cable from it.
Output
Here we come to the end. Now you know why the tablet stopped charging, what to do in this difficult situation and how to use the device correctly in order to avoid similar problems in the future. The main thing is not to neglect the advice of our experts, and then the device will serve you much longer.
Is your favorite tablet not charging? What to do? In fact, this is a fairly common problem on mobile devices, especially tablets. But everything, as always, can be solved - we will help you find the causes and understand the ways to eliminate these problems. You can cope with some problems yourself, and with some you will definitely need to contact a specialist.
Immediately, we want to draw your attention to the fact that you need to contact the service center only before the expiration of the warranty period (the information is in the documents for your tablet).
In any other cases, it is better not to go there, because the repair is terribly delayed, they are not responsible for the quality, and the sellers (receivers) are trained to advise you to buy something unnecessary. If the warranty period has not yet passed, then there is no other way out but to contact the service center. There they must establish whether the malfunction has occurred due to external influences and if there is no mechanical damage on the tablet, then you will be obliged to repair it free of charge. In the case when the warranty period has already expired, experience shows that it is more expensive to contact the service center. I say this already from personal experience... What they wanted to take from me there for 1,500 rubles (but, by the way, they could not do it) in an ordinary workshop (street pavilion "express repair") was done quickly and for only 500 rubles.
Let's return to the topic of mechanical damage ... With tablets, these same mechanical damage happens just very often, since people buy them to constantly have them with them, and when they have them, they can drop them, leave them in places where they fall, pour them over, etc. Therefore, be careful, try to keep the tablet in a cover, and insert the charger into the socket carefully, as it can be loosened. But let's not get ahead of ourselves. Let's list the reasons why the tablet may not accept a charge.
MAIN CAUSES OF NO CHARGING AND METHODS OF THEIR ELIMINATION:
Let's start with chargers. CHARGING DEVICE tablets are different. Some are solid, while others are arranged according to the cable + adapter principle. Here are photos of both options. As for solid chargers, and for a cable + adapter, breakdowns can be the same, the only difference is that you cannot replace the cable separately with a solid charger, you need to change the entire device. In the system, the cable + adapter can be replaced with either one or the other. So, from more common problems to less ...
CABLE out of order. This is perhaps one of the most frequent reasons lack of charging. Some people often have to twist the cable to put it in a bag or put it on the table. Due to frequent twists and bends, the wire inside the cable breaks, the contacts are lost and the cable, thus, becomes unusable.
The second problem is ADAPTER ... It happened to me exactly. Assuming that the charge does not go due bad contact with a nest, I stirred this nest. Eventually, the tablet socket moved and also deteriorated. And it was necessary to replace the adapter, because, despite all its charms - it was working, dear, everything is fine, but - the adapter plug had little contact with the wires in our Russian sockets, tees and extension cords. The charge, therefore, was constantly lost - the tablet was either charging or not. When the charging is turned off and on, the screen lights up, which in turn absorbs the charge. It often happened that due to frequent such outages, instead of charging, there was a discharge. It was not immediately possible to notice this ... Therefore, check how well the plug of your charger contacts the outlet.
This was a problem with a working adapter that could "dangle" in the outlet. The adapter itself may also fail due to sharp leap voltage, overheating or poor quality. Both problems described are solved in one way - by purchasing a new adapter. It's good that a large assortment of them has now appeared in stores. When buying an adapter, be sure to pay attention to the amperage in it. To find out which adapter you need, look at the old adapter of your tablet, there should be written in small numbers 1.5A or 2A. Buy an adapter with a current strength of at least yours. A little higher is possible, lower is not desirable - it will not work for long and it will be bad to charge (if at all).
BATTERY
Among other reasons, there may be a failure battery... If the tablet, and accordingly the battery, is new, then the reason for the failure of the battery is most likely a manufacturing defect.
Over time, the battery can also fail due to the loss of capacity due to the natural depletion of the charge cycle limit. If the warranty period for servicing your tablet has already expired, and there are problems with the battery, then you will have to buy a new one, although this is very undesirable, since after repair its reliability decreases.
PORT (connector / charging socket)
The charger connector can also cause the tablet to not receive power. Problems can be different, mostly this happens due to mechanical damage. You may not remember when you hooked your mobile computer in such a way that the socket was damaged.
If you have already determined that your charger is in good order and other phones and tablets can be powered from it; that contact with the outlet is normal, but the charge still does not go, then you should pay attention to the state of the port. To do this, it may be enough just to move the charger in the socket and see if the charge receipt icon appears on the screen. But, perhaps, this will not be enough, if the matter is not in contact with the charger, but in the breakdown of the socket, in which case it will need to be replaced, and this will require the help of specialists. As mentioned above, it is not at all necessary to contact the service center for help (it is not even desirable if you want to quickly, efficiently and inexpensively). Replacing the port in private computer repair shops costs about 500 rubles (together with the cost of the nest itself).
POWER CONTROLLER
There is also such a microcircuit in the tablet, which is responsible for the distribution and supply of power to it. The reason for the failure of this part is also mechanical damage. If the controller is burnt out, the device battery will not charge. It is clear that only specialists can fix such a problem. For a good master, this is not a difficult job.
FIRMWARE
Firmware is the reinstallation of the tablet operating system. Sometimes the firmware is unsuccessful, but since only the owner of the device can initiate the firmware, no warranty repairs apply to the flashed tablets, and if you need to reflash, you will have to do it at your own expense. As a result of a firmware error, the device may not charge, since the installed operating system.
A firmware error can occur when the tablet turns off on its own due to a low battery, when the system is shut down incorrectly. Try restarting your device. If you are sure that there is no charge for this reason, then you can try to reset the settings to the factory settings. If this still does not help, then there is another option - to reflash the tablet. Also on the Internet you can look at articles on the topic "firmware error", there are tips on what else can be done in this situation.
All of the above cases can be both the reason for the complete absence, and the reason for very slow battery charging. Or both together. In general, this often happens. At first, the tablet charges more and more slowly, it reaches the point that it does not fully charge for several days. Then, after some time, the charge ceases to flow at all and the tablet does not turn on at all ...
Some causes of malfunctions can be identified independently, for example, check whether your charger (adapter and cable) is working, whether there is good contact with the network, whether there is a large voltage transfer in the network ... Other problems, as you already understood, can only be identified with the help of specialists.
One more small nuance ... having come to the store for a new charger, before buying it (or cable / adapter), you need to check the operation of the device on your tablet. If none of the commercially available charges your tablet, then there is no point in buying a new charger - the problem is inside the tablet and you should first seek help from specialists.

With all the functionality and reliability, modern gadgets are not without drawbacks - they periodically fail and need to be repaired. If the tablet does not charge, turns off after turning on, freezes or works slowly, it should be shown to the master. The causes of problems can be very different - it is often impossible to determine them without having the necessary diagnostic equipment at hand. Only a professional with many years of experience in servicing devices can answer the question of why the tablet is quickly discharging or not charging. Nevertheless, it is desirable for every tablet computer user to have a basic knowledge of the principles of its operation in order not to sound the alarm in case of breakdown and to avoid malfunctions.
If your tablet stops charging - how to find out the reason?
Many users of modern gadgets are unhappy with the fact that their "assistants" are discharged in a few hours, it is absolutely impossible to work with them far from the outlet. However, fast battery drain is a problem with most devices and can be dealt with by adjusting the settings or using a portable battery. Much worse if new tablet does not charge when connected to the network - in this case, the device requires complex diagnostics and competent
Malfunction may result in failure of the following elements of the tablet computer:
- cable (the wire can be damaged both during operation and during storage - being coiled);
- charger adapter (breaks down due to overheating or power surge);
- storage battery (it may lose capacity as a result of natural wear and tear or under the influence of external factors);
- connectors (loose and deformed);
- power controller.
If a wire is the culprit, it must be replaced. It is convenient and beneficial to use a USB cable. If the tablet stops turning on and charging due to the fact that the limit of charge cycles has been exhausted, it is worth buying a new battery, it is advisable to repair the existing one in rare cases.
How to solve the problem with a long charging of the tablet
For those who prefer to use touch devices, buying a tablet computer is an absolute must. With it, you can access the Internet, create graphic and text files, process large amounts of information. The only drawback of modern tablets is that after a certain period of time they charge slowly and discharge quickly. However, this problem can and should be fought - the main thing is to determine what factors led to its occurrence. If the tablet battery takes a long time to charge, you may be experiencing the following problems:
- the battery is worn out;
- the connectors for connecting the USB cable are deformed;
- the voltage in the network has dropped significantly;
- defective charger;
- a factory defect appeared.
In some cases, it can be concluded that the device has failed due to the fault of the user. The battery charge is often disrupted due to careless handling of the gadget - its pollution, wetting, virus infection. If charging your tablet computer takes too long, you should take the following measures - change the outlet, replace the worn out cable, install a new battery. If you cannot solve the problem yourself, and the tablet still charges slowly, you should contact the wizard. He will diagnose the device and establish why the battery cannot be charged within the prescribed time.
How much should the tablet charge
Charging speed and time autonomous work - important criteria for choosing a gadget. The duration of the device's operation without recharging is determined by the volume of the built-in battery, and how quickly the tablet is charged depends on it. Devices of well-known brands can work autonomously for about 10 hours, devices that do not reach this indicator are also presented on the market. Before you buy a tablet, you should ask it technical characteristics and read user reviews. In most cases, the tablet takes 2-6 hours to charge - the newer the battery, the faster this process takes place. The service life of the battery is significantly less than the service life of the device, so it will have to be replaced every 2-4 years.
The tablet does not charge when turned on, how can I fix the problem?
If the switched off device cannot be charged, first of all it must be turned on and in this state it must be connected to the charger. If the tablet is charged only when it is turned off, do not panic - this is not a breakdown, but a feature of the device. In most cases, the situation can be corrected. The main thing is to understand what caused it. Tablet PC Charges only off if: an unofficial operating system is installed, the power supply is faulty, the contacts are clogged, the cable is damaged. To be able to charge the device while it is on, it is worth reflashing, testing the charging and USB cable, wiping the contacts from dust with alcohol. Experts recommend charging the gadget exclusively with a "native" device, otherwise the battery capacity may significantly decrease. Original components can be purchased at the company store or service center.
Where to get your tablet charger repaired
Only real professionals can quickly and efficiently - independent intervention in the operation of the device often leads to new breakdowns. Repair charging the tablet and replacing its battery can be entrusted to specialists service center... They will diagnose the gadget and answer in detail the question of what exactly caused the problem. Only original accessories should be available to workshop staff. It is desirable that the quality of the work of specialists be documented. Reliable SCs offer a long-term warranty on all types of services.
