The Lenovo tablet is charging but not charging. 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

Problems with charger - the very first and most common reason why the tablet does not charge is a faulty 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 burned out and you need to contact service centerwhere 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.

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 charged only off if: unofficial installed operating system, 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 the specialists of the 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.

If suddenly your smartphone, tablet or phone stops charging or turning on, do not immediately get upset and run to the service center. We will tell you what you can do to try to solve the problem you are experiencing. We do not guarantee that the following tips will help you. But it's worth trying.

Try restarting your device. If it freezes, press the power button for 5-10 seconds. If it does not help, try the combination "On / Off" and "Volume up" or "On / Off" and "Volume down" (you need to simultaneously hold down two buttons for a few seconds).

If the device is discharged to zero, the first signs of life from the gadget will have to wait a few minutes (or tens of minutes if you are using a charger with low amperage). You can even leave your smartphone on charge for several hours.

Maybe, defective charger. Try another, known working network memory. Or try charging your phone using a computer. Please note that if the current from the charger is too low, some smartphones and tablets will not charge at all. Even if the charger is working properly.

Try charge in the off state. If the smartphone / tablet draws more current than it comes from charging, it will discharge faster than it will charge. In this case, leave the gadget alone, or turn it off. Devices charge faster when off. Do not forget about this if you need to charge your phone to the maximum in a short time.

Maybe, defective cable. This rarely happens. But check the charging with a different cable anyway.

Sometimes there are connector problems. Dirt can get into the microUSB connector on the phone, internal contacts can be bent. Try to blow through the connector, gently clean it with a scrubber. The connector can simply break or loosen in the socket.

Besides, microUSB connectors on cables come in different shapes. I was somehow helped by replacing one cable with another with a slightly different connector configuration.

Sometimes it helps to activate simple charging poking / inserting the cable from the charger, as well as poking / sticking the charger in different sockets. This does not solve the problem, but if you need to recharge urgently, you can try.

Finally, you can try hard reboot. Please note that all your data from your smartphone will be deleted (!) Press the "Volume up" button, and then the power button. After the appearance boot menu using the volume control buttons, go to Setting, then Format System and Reset Android. The selection is made by the power button. The tablet will reboot and be recovered naked android system... And it's not a fact that it will help.

Tips for using modern gadgets
Previously, we were taught that it is advisable to discharge phones to zero, and after buying a new device, make two or three full discharge-full charge cycles. These tips were relevant for nickel metal hydride and nickel cadmium batteries. Modern lithium polymer batteries do not need these procedures. They do more harm than pain. Modern smartphones and tablets do not recommend discharging before turning off - put the devices on charging if the charge level has dropped below 50%.

I will also answer another popular question: which charger is the best for charging gadgets. The best option: use the charger that came with the kit.
In this case, you can charge phones and tablets with any other chargers. If the amperage is less than necessary, the gadget will charge more slowly than usual. If the current is greater, the charging controller built into the smartphone will limit the current to the required level.

Any modern electronics can also be charged from USB connectors on PCs, monitors, etc. In this case, you will receive a current of 500 mA (USB 2.0).
