What to do if the smartphone does not turn on. Phone turned off and won't turn on. Chargers for phones.

imagine life modern man without mobile phone almost impossible. Today, this gadget is used constantly for personal and business communication, and options in the form of smartphones are great for browsing the Internet, entertainment, and so on.

It's a shame when at the most inopportune moment this device stops turning on.

Types of mobile phone malfunctions:

A malfunction with any device can happen for a variety of reasons and cell phones. The factors that can cause problems with the machine depend on the brand and model.

At the same time, you can identify the main common reasons why the phone does not turn on and try to eliminate them before contacting service center on one's own.

Consider the main causes of cell phone malfunctions in which it may stop turning on:

Battery check

The first thing to do if the gadget does not respond to pressing the Power button is to check the battery.

The main problems that can occur with a cell phone battery are:

low charge level;
wear and tear;
swelling and other damage;

A dead battery may prevent the device from turning on. Depending on the level of the remaining charge, they may be completely absent or show only some signs of the life of the device. Solve the problem easily by connecting the phone to the charger.

Important! Some models after discharging and connecting the charger do not turn on immediately. In this case, it is necessary to leave the device on charge for a longer time, for example, for 1-2 hours.

When to solve a problem simple connection charger fails, you must open the back cover of the device and inspect the battery. If it is swollen, then it needs to be replaced.

When the battery wears out, the device will usually turn on, but the battery will drain quickly. If necessary, you can check whether the battery is worn out by measuring the voltage and current.

Advice. You can also check the battery by installing it in another device of the same model. If everything works there, then the problem with the battery can be ruled out.

Charger

If, after connecting to the network, the phone does not charge, then in many cases it is not the battery that is to blame, but the charger.

check the presence of voltage in the socket;
replace the cable;
use another charger.

First of all, you need to make sure that there is power in the outlet to which the charger is connected. No matter how ridiculous it may seem, but this is the most common problem with charging any gadgets. That is why the support specialists of large companies start the conversation with the question of whether the user is sure that there is voltage in the outlet.

The charger cable for connecting the phone suffers much more often than the adapter itself. This is due to careless operation, pets that damaged the wire and other reasons. Most modern cell phones charge using a mini-USB or micro-USB connector and allow you to change the cable without changing the adapter.

You can buy such a cable in any communication salon or computer store, in addition, usually the user has several identical cables at home.

Advice. You can often check the operation of the charger by putting the device on charge from the computer. If the process goes without problems, then it is definitely necessary to replace the adapter.

power button

The power button can also cause trouble for cell phone owners. It can fail, for example, after an impact. Sometimes problems with the button can be seen during an external examination, and in other cases it is difficult to diagnose a malfunction on your own.

Most users will not be able to solve the problem with the Power button at home, so if you suspect that the handset does not turn on because of it, you should contact the service center.

Updates

Installing updates is designed to solve the identified problems with the device. In practice, this operation can lead to unpredictable consequences. It must be carried out only by understanding and taking into account all the risks. For example, handsets running Android often begin to consume battery faster after an update.

In some cases, the update leads to the fact that the gadget completely stops turning on. Many users faced such a problem in 2015 when they tried to update the Androyd operating system to the latest versions.

Consider the main ways to solve problems that have arisen after the update:

rollback of a version or updates;
installing another version;
restore the device through a special mode.

If none of the methods can be applied independently, then you will have to seek help from specialists.

Important. In some cases, updating can significantly improve the performance of the gadget, for example, by increasing battery life. Therefore, it is necessary to evaluate the possible pros and cons before performing this operation.

Mechanical damage

Very often, phone users encounter startup problems after various mechanical damage. They occur when the phone has been dropped or dropped into water.

Many falls are not even noticed by gadget owners or they occur even without their knowledge, for example, when using a smartphone by children. But the most common consequence - problems with the screen is quite obvious.

In cases of mechanical damage, it is impossible to carry out repairs on your own and you need to contact specialists. It should be borne in mind that the cost of replacing some parts can be comparable to the price of the device.

If the user accidentally drowns the phone, then moisture gets inside, which can damage contacts and other electrical parts. In this case, you should contact the service center as soon as possible. In this case, do not try to turn on the device. It can only cause additional harm.

Moisture can get into the phone and not only as a result of getting into the water. It is enough for the device to lie in a damp room for several hours and the consequences can be irreversible. This must be taken into account when operating the devices.

Modern cellular telephone a fairly complex device, the independent repair of which is almost impossible to perform at home. The user, if the device does not turn on, can only try to solve minor problems, for example, by replacing the battery or charger.

In other cases, you will have to contact a specialized service center. At the same time, special attention should be paid to his choice, since a huge number of companies operate on the market and not all of them can provide high-quality repairs. In addition, phone repairs can be expensive. Often it is only suitable for expensive models.

Few of the owners of mobile gadgets have not encountered a problem when their favorite device stops responding to any actions. No matter how expensive and reliable the equipment is, it tends to throw tricks and fail from time to time. If your gadget does not turn on, then you need to establish the cause of this and, if possible, try to fix the problem yourself. Problems can be both software and hardware. Consider possible reasons why the gadget does not turn on and the main ways to solve problems for a Lenovo phone, tablet and laptop.

Phone does not turn on

Below we will consider the main problems that prevent the gadget from functioning normally.

A fall

The most common cause of any phone breakdown is when it falls. Sometimes even a small height is enough to make your device “silent”. If the reason that the Lenovo phone does not turn on was its fall, then without certain skills it will not be possible to deal with this problem on your own, so the only thing worth doing is contacting the service center.

Fell into the water

Also, very often the phone does not work after contact with moisture. This damage can be eliminated, but you need to act very quickly. After the device gets wet, it is necessary to remove the battery, and dry the gadget itself with an ordinary hair dryer with low airflow, and then put it in a warm place, covering it with a thin cloth.

However, not all modern phones are equipped with a removable battery, and by the time you remove it, all contacts will have time to oxidize heavily. Therefore, it is worth mentioning separately the old proven remedy - rice, which is the leader in absorbing excess moisture. You just need to put your phone in a bag of rice and wait only 2-3 hours, and then try to turn on the device again.

The battery is completely discharged

Modern gadgets have one feature. The device does not turn on due to the complete discharge of the battery, even with the charger connected. What to do then? As a rule, the problem disappears by itself, but if this does not happen, you can try to push the battery with a universal “toad” and connect the phone to a regular charger. However, this option is only suitable if the battery is removable.

Another most common cause of a hardware nature is the breakdown of a smartphone when it is connected to a charger. This may be caused by a power failure or a malfunction of the charger itself. In the charger, the connector very often breaks or the filling fails. In this case, you need to make sure that the charging is working, and if it works, but the phone still does not turn on, then you should contact the service center for help.

However, the problems do not end with hardware problems, but only begin. Often, malfunctions can be programmatic in nature. What to do in this case? In this situation, the solution to the problem that has arisen is different from those described above.

Software failures

Often, modern phones, especially those running on WP, iOS and Android platforms, do not start due to various kinds of failures in software. This can be caused by the clutter of the operating system, virus infection, or an elementary violation in the operation of certain files. The manufacturer has provided a way to solve such problems - resetting the settings (although all data is lost during it). So it's better to make a backup beforehand.

Those who have as operating system used Android, such as Lenovo, a little easier. Recovery in the Recovery program will help solve the problem. To enter its menu, you must press a combination of the indicated buttons (depending on the model) and hold them for a while:

key to turn off the phone and increase the volume level;
simultaneously pressing the lock button and volume down;
decrease or increase the volume while pressing the "Home" key and the device's power button.

After entering the Recovery menu, you need to open the "wipe data / factory reset" submenu, go to the Yes tab - "delete all user data" and confirm by clicking "reboot system now". After that, a reboot should occur and the phone will turn on.

If the results from these actions are zero, then the only thing worth doing is to turn to qualified craftsmen.

Tablet won't turn on

If your Lenovo tablet does not turn on, do not panic, but calmly figure it out. There may be several reasons and in some ways they are similar to the described problems for smartphones. But let's take it in order:

operating system failure;
mechanical damage;
low tablet charge.

The most rare cause is the failure of the video adapter. That is, the gadget itself functions, but the display remains dark.

Trouble-shooting

If the problem is a failure of the tablet operating system, which happens quite often, then it is worth updating the firmware. But you can do this procedure yourself only if you have already successfully carried out such operations before. If this is for you dark forest”, then it is better to consult a specialist. Yes, and it is worth remembering that in case of flashing, you can forget about the warranty for your Lenovo tablet.

In the event of a fall, the gadget is also not subject to warranty replacement or repair, so again, a direct road to the service center. Although some masters replace damaged parts of the tablet on their own, but in order to do this, you need to have the appropriate knowledge and experience in this area.

If the battery is just dead, then you need to charge it. It is worth mentioning that some tablet models may not be charged from a computer.

If the video adapter fails, then, as a rule, this is due to the frequent overheating of the device, which is why it stops functioning. In this case, you will also have to contact the official service center or take your Lenovo tablet to the store under warranty, unless of course it is still valid.

Laptop won't turn on

If your faithful and beloved laptop decided to buck up and does not turn on as before, then do not fall into despair, but rather figure out what caused this malfunction. Both the causes of the problems and the ways to solve them will be discussed below.

Try removing the battery from the gadget. If after that the laptop turns on, then the dead battery is to blame or a short circuit has occurred in it.

You can try to remove the battery from the device and disconnect the gadget from the network. You need to wait a bit, then charge the battery and start the laptop. In some cases, this helps and the device turns on.

Sometimes the fault can be the failure of the power button. To determine this on your own, without the necessary experience, is unlikely to succeed.

But, the worst option, in which the Lenovo laptop does not turn on, is a breakdown of the internal power supply. Since it is located on the motherboard, you can only fix the problem in a service center, and you should not attempt to fix the problem yourself.

Faced with some kind of breakdown of a phone, tablet or laptop and having no experience in repairing electronics, it is better to contact a specialized workshop. You should not make unnecessary problems for yourself, because the service center will not only fix the malfunction of your gadget, but also clean the system of debris, and also do preventive maintenance of the device.

Has your phone suddenly turned off and won't turn on? Discharged to zero, and does not start even when the charger is connected?

Many mistakenly believe that the battery is out of order, and spend money on buying a battery, although in most cases the problem is not in it.

The battery cannot fail suddenly. If up to now the phone has been working properly, and the charge was enough for at least one day, then it is unlikely that the problem is in it. More precisely, it may be in the battery, but the problem is solved not by replacing the battery, but by other actions.

So, if the phone turned off and does not turn on, then the problem may be in the battery, in the phone's firmware, and also on the motherboard (in the power circuit).

Before taking your phone to a service center, we recommend that you do the following:

1. You need to take a charger with increased current (more powerful). Nominally, modern phones consume 5 volts, the current strength sufficient to support the charge is from 0.4 to 1 ampere. But if the phone's battery is completely discharged, then it may require increased current to start, more than 1 ampere, and on some smartphones - more than 2 amperes.

Therefore, we recommend taking a power adapter from any tablet with 5V 2A or 5V 2.1A characteristics. Connect your phone to it using a data cable and leave it to charge. If after 15-20 minutes the phone does not turn on, then the problem is not in the battery.

2. If the phone turned off suddenly, or during charging, or during firmware, and does not turn on anymore, then most likely, you need to flash the phone with bootloader recovery. Please contact the service center.

3. The most unpleasant, but alas, the most likely option is the burnout of the board, damage to internal elements. Usually, a service center diagnoses this problem as a failure of the power controller.

Alas, this is not treated in 90% of cases. Why? On most phones, part of the power circuit is located under the compound (resin on the board), it is practically impossible to remove it without damaging the tracks, and there are stencils that can be used to restore the wiring, only for a few phone models.

How to avoid damage to the board and failure of the power controller?

The advice is very simple: do not buy cheap Chinese chargers. The current strength in them does not exceed 0.7 amperes, while the voltage regulator is either very weak or absent altogether. With any heavy load in the mains, increased voltage can get on the phone, which leads to problems on the board. Any element can burn out - both the power controller and the processor, or flash memory.

Use either the original charger or certified chargers with a current of 1A or more. Ask at the point of sale for a certificate for chargers.

What to do if the phone does not show signs of life? First of all, do not immediately panic and tear your hair on your head! After all, this does not always mean that it is broken and you can often solve this problem on your own without going to a service center and spending extra money on diagnosing a gadget. There may be several reasons why an Android smartphone does not turn on.

Low battery

Perhaps you just forgot to charge your device. Often this is the main reason why the Android phone does not turn on. This problem is solved very simply - recharging. In some cases, after discharging to zero, the phone does not want to turn on. The fact is that the battery has spent all its energy and it simply does not have enough power to turn itself on.

Plug your smartphone into the network for a few hours and leave it. Most often, after some time, the battery will still start charging and the device will turn on.

Device reboot

When the phone does not turn on, it is quite possible that it is frozen and needs to be restarted. If the device is collapsible, then we take out the battery and insert it back. Let's try to turn it on.

In non-separable devices, almost all manufacturers have provided a special button that makes a forced reset. Carefully inspect the case or read the instructions. For Sony phones, for example, this button is located near the memory card slot under a flap.

Software problems

The phone may not be completely turned off because some program is interfering with it, although the screen is dark or the initial splash screen with the logo is shown on it. A forced reboot can also help here.

Also, such problems arise when the user has installed custom firmware or the system update is crooked. It will have to. But this action will delete all the data that is in the phone. If most of them are stored on a USB flash drive, then it's okay, just remove it before resetting.

To reset to factory settings, you need to go to the engineering menu of the device. This can be done through the standard settings, but our device does not turn on. To do this, hold down the volume up button and the power button. In some phone models, you will also need to hold down the Home button.

Not everyone will be able to do this the first time, so try until the menu appears. Use the volume rocker to select:

"wipe data/factory reset";
"Yes - delete all user data";
"reboot system now".

The phone will reboot itself and turn on.
