What to do if your phone turns off and won’t turn on. Samsung Galaxy won't turn on - restoring the smartphone's operation. What to do if the phone does not turn on

There are many reasons why a smartphone may not turn on: from banal discharge to mechanical failure. And if you are reading this, it means this problem you are probably familiar with it firsthand.

Let's look at the most common common causes and how to eliminate them yourself. Let’s divide these reasons conditionally into two groups: those that the owner of the gadget had a presentiment of and those that were completely unexpected, thereby especially unpleasant.

The first includes cases like:

• The power and lock button does not always work. And when once again you were unable to turn on the phone after several attempts, it seemed obvious that the button mechanism was completely out of order. What you can do yourself: remove back cover phone, if of course it is collapsible and evaluate the integrity of the button mechanism, the presence of dust and dirt. Try to gently clean the button with a brush. If the button fails due to exposure to water, moisture, or condensation, then chemical compounds that are sold in specialized stores for repairs can help. mobile technology. Spray inside the button, wait a little and repeatedly develop the button mechanism. If there were slight oxides and corrosion, then this procedure will definitely help. If the proposed measures do not have the desired effect, then unfortunately you cannot do without our services.
• The battery on the phone was draining quickly. The most likely reason here is that the battery is deeply discharged and the phone will not turn on. For removable battery There is an option to charge it using a special “frog-clothespin” device from the mains. You can try charging a non-separable device powerful charging at 1.5-2 amperes, for example from a tablet. If the battery cannot be charged using these methods, this is also a reason to contact service center for phone repair.

Unexpected reasons for the phone not turning on include many defects. Here are the main ones:

• Software glitch, software failure. Here, only a forced reboot can be attempted independently. This is done by simultaneously pressing two buttons. The combination of these buttons on specific model You can look it up in the instructions for the gadget or on the Internet. It didn’t help - we’re waiting at the service center.
• The charger connector has stopped functioning. Carefully examine the charging socket; there may be dirt or something foreign in there. The only option is to clean it. Using a needle, brush, brush. Just be extremely careful. No effect is also a reason to contact a service center for diagnostics.
• Don't forget to check your charger. Perhaps it is simply a matter of its failure. And the phone does not turn on simply because it is not charging.
• The most unpleasant problems are internal, hardware malfunctions caused by mechanical stress, liquid getting into the phone, or natural wear and tear. The range of such defects is extremely wide, and unfortunately, it cannot be avoided without qualified intervention. Anything may be needed here: restoring the power circuit, replacing the charge controller, replacing flash memory, replacing the power controller, the need to install a new display, battery, and much, much more. In all these cases, you cannot do without the help of a competent engineer. Moreover, independent attempts to disassemble and repair the device can only lead to more serious consequences when replacement is required. motherboard entirely.

Remember that modern mobile phones are complex electronic equipment and without special knowledge you can only make things worse.
If you are after self-diagnosis If you find out that your smartphone needs the help of a specialist, bring it to our service center.

Quite often you have to deal with the fact that the device does not work mobile communications, or rather, it does not turn on. This can happen for a number of reasons. In this article we will figure out why the phone does not turn on.

First of all, don't be upset because:

• Firstly, such incidents happen quite often to many mobile phone owners, and, basically, the issue is always resolved.
• Secondly, this happens with almost any phone. The answer to the question why it doesn’t turn on Nokia phone or LG, Samsung or Motorola, the same.
• Thirdly, you need to understand that sometimes the owners themselves aggravate the situation by not understanding the reason why the phone may not turn on.

Let's consider possible reasons, for which the mobile communication device may not turn on.

Discharged battery

The phone may be dead. This can happen to anyone. They forgot to charge the phone in the evening, and by the morning the phone was dead. If after starting charging the phone still does not turn on, there is no need to lose hope. You should leave it to charge for 24 hours. If after this the phone does not turn on, you should look for the reason in something else.

Battery is faulty

Perhaps the battery has become unusable. To find out, you need to open the back cover of the device and inspect the battery very carefully. If it turns out that there is swelling on it, then the problem lies in its unsuitability.

The charger has become unusable

The problem may be that the charger is faulty. This also happens quite often. If possible, check the charging operation on another device. If it turns out that it is working properly, then the reason needs to be looked for elsewhere.

Memory card lock

If the phone has additional slot for a memory card, and it is inserted there, this may also be the reason why the phone does not turn on. It is quite possible that the card is blocking the startup process of the mobile device. This can happen especially in cases where it is filled with information. If, after the card is removed from the slot, the phone still does not turn on, then the reason is different.

Mechanical damage

A very strong mechanical impact on the handset could occur, resulting in a breakdown. It is impossible to determine this from the external data of the case; it may be absolutely intact. Most likely, the internal mechanisms of the mobile communication device could have been damaged.

What most often leads to mechanical damage:

• phone falling to the ground;
• crushing in the pockets of tight jeans;
• damage by small children or animals;
• leaving the device on the roof of the car by the owner;
• crushing in the bag.

In the event of such a breakdown, it is not recommended to open the phone yourself; you need to contact a specialist.

Moisture ingress

Moisture can get into your phone, not necessarily due to direct exposure to water. To do this, it is enough for it to simply lie in a damp room. You should not try to take any steps on your own; you need to go to a specialist.

Possible causes of moisture ingress:

• falling into a bathtub of water;
• falling into the toilet;
• falling into snow;
• use in the rain;
• falling into a pond;
• fogging of the phone caused by its owner performing heavy physical work;
• leaving the phone outside during rainfall.

Other reasons

• If your smartphone does not turn on, there may be a software failure. For example, a firmware update or rollback may be required.
• The power button is broken. It is very difficult to understand this on your own. Such cases are quite rare, and they can occur as a result of a fall. cell phone from a great height.

We have considered almost all possible reasons why the phone does not turn on. It doesn't matter whether it's Samsung or any other model of the device. As a rule, the reasons for this phenomenon are the same.

Most owners modern gadgets More than once we encountered situations where the device malfunctioned or did not respond to commands. Unfortunately, almost all smartphones fail from time to time, regardless of manufacturer and price.

Today we will look at the problem when a Lenovo phone does not turn on, and we will look at the reasons for this.

Lenovo cell phones often suffer from problems with software and hardware components, especially if we are talking about budget models. One of the most common is spontaneous shutdown and lack of subsequent response to different actions user. Although the situation seems dire at first glance, only in extreme cases will it be necessary service repair or replacing a smartphone. There are three types of sources of these breakdowns:

• Hardware - a problem in the hardware after falls, temperature fluctuations, tests by the sun, moisture and sand.
• Software – directly concerns operating system, viruses and crashes.
• External – most often, a breakdown of the charger is mistaken for a problem in the smartphone itself.

Let's take a closer look at the reasons why it doesn't turn on. Lenovo phone, and ways to solve them.

Trouble-shooting

IN this section we will look at the most common faults that cause Lenovo to not turn on:

• Complete battery discharge and other related battery problems.
• Firmware update failures.
• Software problems.
• Virus attack.
• Mechanical damage to internal parts.

Battery completely discharged

Battery problems can be temporary or permanent, and they different ways solutions:

Incorrect system update

From time to time, the Android OS firmware and its shell are updated, but glitches may occur during the process. Often after installation new version system technology turns into a non-working “brick”. However, do not rush to replace it with another model; this can be solved by rolling back to factory settings.

It is done using Recovery Mode. Three buttons are pressed simultaneously in the following sequence:

• Volume rocker.
• Without releasing the previous one, return to the Desktop key.
• In parallel with them there is a power on and off button.

A menu will appear on the screen. The pointer moves with the volume rocker up and down respectively. You must select an item Factory Reset, confirm your choice and wait for the process to complete.

If after this the smart device does not work, then you need to contact a specialist, and he will do the flashing of the system himself.

Software glitches

Even more often, Android-based cell phones do not start due to various software failures. The manufacturer and system developers have provided for such scenarios, so they advise you to reset the settings in similar cases. We have already discussed how to do it above.

Please note that pressing the keys in succession will not work to start recovery mode on some models. It starts special button at the end of the body, which looks like a small hole, using a needle or a special pin that comes with the kit.

Viruses

Viruses are another popular reason for difficulties with Android technology. They get through downloading files and applications from unknown sources, and can seriously damage system data needed to run. Most likely, a flashing will be required, which will completely delete the information. But in some cases, service center specialists still undertake manual cleaning. system storage from viruses and malware.

You can avoid this outcome by first downloading anti-virus software, for example, Dr.Web or ESET.

Mechanical damage and moisture ingress

Let's look at the most popular types of mechanical damage that prevent switching on:

• Screen failure (malfunction of the cable, display, or moisture ingress through the seams).
• The charging socket is dirty. Dust, fabric threads from clothes or crumbs get into it. you need to be careful, using a regular needle.
• Damage to gadget contacts with batteries. This can be either oxidation or mechanical stress that led to deformation.
• Damaged power button. If the device is new, then most likely it is a factory defect.
• The worst option is a burnt-out power controller that controls charging.

Ask a question to a virtual expert

If you still have questions, ask them to a virtual expert, the bot will help you find the problem and tell you what to do. Talk to him about life or just chat, it will be interesting and informative!

Today we cannot imagine ourselves without means of communication, such as mobile phone. Sometimes the phone breaks down for reasons unknown to us. To understand why it refuses to work, we offer for consideration the main reasons for the phone to break down.

Visually inspect the phone for mechanical damage. If none are observed, the battery may be low. You should charge your phone by leaving it plugged in for a day. If after given period the phone does not respond to commands, you should contact specialists at the service center.

Mechanical damage

If damage is detected on external parts (case, display, keyboard), they can be replaced, either independently or with the help of a specialist.

No network signal on the phone

There are probably several reasons for this:

1. This network is not supported by the operator. Replace the SIM card with an operator that supports the network in this locality.
2. The antenna (radio path) may have failed. Only a service center will help you cope with this problem.

There is no image on the display

The main reason is moisture, which for one reason or another got into the phone. The problem is usually fixed by cleaning the phone.

The reason most often lies in software glitch provision. The second reason is if the phone often fell. They will help you only at the service center.

Phone quickly drains

This usually indicates that your battery is bad and should be replaced. Another problem may lie in the power amplifier if the phone is discharged when receiving a call or dialing (due to the fact that the phone was often dropped). We replace the battery; if it doesn’t work, then we go to the service center for help.

The smartphone does not see the SIM card

Several reasons for this problem:

1. this SIM card has expired;
2. the SIM card has run out of money;
3. not supported by this operator;
4. dirt and oxidation on the SIM card;
5. it's the card reader

Turning off the phone itself

There may be a failure in the self-sufficiency program. Poor connection between the battery and the phone contacts. The elements or itself have failed printed circuit board(at mechanical damage). Low air temperature can also be one of the reasons why the phone turns off.

If you have serious problems with your phone, go to the service center for help!

Read why your phone won't turn on. In the article you will find the most common reasons for this behavior of smartphones. And also ways to fix it.

If your phone turns off and won't turn on, or simply refuses to work, this can become a serious problem. Next we will discuss how to correct this situation. If the smartphone stops turning on, measures must be taken urgently.

Since without this device we will lose calls, text messages, the ability to instantly receive information from the Internet, favorite books, games, video cameras and cameras. It should be noted that the user often has the opportunity to independently bring his phone back to life, without the need to contact representatives of service centers.

Your phone won't turn on? Check the battery charge!

Obviously, most often the phone turns off and does not turn on if the battery charge drops to zero. IN in this case, solving the problem is incredibly simple, just connect the phone to the charger. Please note that if the battery is completely empty, the device will take some time to display information on the screen that the charging process has begun.

The problem may also be in the charger itself; sometimes its power is not enough to fully fill the battery. This situation sometimes occurs if you are using a charger that was not included with the phone.

• or "Frog" will help get rid of this problem.

If the design of the smartphone allows you to remove the battery, it can be inserted into a special charger, nicknamed the “frog”. If your smartphone has a non-removable battery, a power bank will come to our aid. Even the owners of new mobile device may encounter the problem of an unexpectedly dead battery. Improper charging of a smartphone is the most common reason such trouble.

Phone won't turn on after charging? Charger fault

Now let's look at the question of what to do if the smartphone does not turn on when it is already charging. The problem may be with the charger itself. It is probably broken or damaged.

• A second charger will solve the problem.

The smartphone can be connected to another charger; if the problem does not recur, then this is the problem.

Battery is faulty

People who are wondering why their smartphone won’t turn on should take into account that the battery in it is designed to last about 2.5 years, after which it can also fail.

• Replacing the battery may solve the problem.

If your smartphone has removable battery, all we need to do is visit a mobile phone store and purchase a new one. If removing the battery is not possible, we will have to go to one of the nearest service centers.

Problem with charging contacts

If the phone does not turn on, the reason for this may also be broken contacts. For this reason, even a fully functional battery will not be able to accumulate a charge.

• It is necessary to correct the contacts by first conducting diagnostics.

It is quite possible that the contacts connected to the battery have come off slightly; they need to be checked. If the assumption is correct, we arm ourselves with thin tweezers and slightly bend the antennae of the contacts. Using a screwdriver for electricians, check whether there is voltage in the connector for the charger. In this case, we note that it is better to entrust such work to a professional master.

External temperature

Summer and winter are a big test for a smartphone. Phones really don't like things that are too tall and excessive. low temperatures. For example, you can fully charge the device, travel on a hot bus with it in your pocket, and then find that the battery is almost completely dead.

• Cooling or warming the phone will help.

We strongly do not recommend charging a supercooled or overheated smartphone. First, you need to wait until the temperature of the device returns to normal and only then connect it to the network.

The power button is faulty

The phone does not turn on if the start key is broken. A thin silicone or rubber membrane is located between the contact and the button itself. Over time, this element wears out and fails. Often the power button no longer works after dropping the phone on a hard surface.

• The smartphone will need repair.

In this case, it is best to take the device to a service center and entrust the problem to a technician. Repairing the membrane is not a very expensive or very time-consuming procedure.

Our advice: do not go inside the phone yourself. If such a breakdown occurs, you will need to replace the membrane, which you are unlikely to have in stock. But carelessly touching elements on a smartphone can lead to much bigger problems.

Memory card problem

The smartphone may decide not to turn on anymore due to difficulties with the SD card. This problem often occurs when purchasing a drive second-hand, or receiving it from another unreliable source. There is a possibility that the card is infected with a virus and it is this virus that prevents the smartphone from turning on. In addition, a similar problem can arise in the case of a fully working SD card, if it is full of information.

• Remove or format the SD card.

The defective drive will have to be thrown away. If the card is full, you can simply format it.

Incorrect system update

A problem with your smartphone may occur if you use unverified sources to download updates for the OS. Such manipulations can completely damage the mobile device.

• Returning your smartphone to factory settings will help.

To rid the device of incorrect firmware, return it to factory settings. This can be done in different ways.

If you use the smartphone menu, the algorithm is as follows:

• Let's move on to the settings.
• Open the “Restore and reset” section.
• We use the “Reset settings” function.
• Press the button located at the bottom of the screen.

In a matter of seconds, the system settings will be rolled back. Next, the smartphone will reboot.

An alternative way involves turning to service teams

It's about about , which you need to type on your smartphone. Let's name the main combinations:

• *#*#7780#*#
• *#*#7378423#*#*
• *2767*3855#

In addition, to return the phone to factory settings, you can use it; to do this, we go through the following steps:

• Clamp Power button simultaneously with the volume increase button.
• From the proposed list of options, select wipe data/factory reset.
• We use the Yes option.
• When the reset process is complete, use the Reboot System function.

Oversized updates

Almost all applications present on a smartphone regularly download updates. This is especially true for elements whose work is focused on accessing the Internet. Such continuously incoming information often overloads the smartphone’s memory.

• Removing updates will help

To reset the updates, remove the battery from the smartphone, after a few minutes replace it and remove it extra elements systems.

Screen is faulty

If the smartphone display is faulty, the device will obviously not be able to turn on, even if it is software Everything is fine. Often the screen does not break instantly, so you should remember the phenomena that often precede this.

Sometimes stripes appear on the display, which later disappear.

There are jumps in the screen brightness, it increases, decreases, the display flickers, but after a while it returns to normal operation.

• Repairs at a service center will help

If there are similar problems, most likely, the display in the smartphone is broken, or the cable with which it is connected to the board has failed.

You can take a risk and try to revive the smartphone yourself, but if you do not have the proper level of technical knowledge, such actions may lead to the final failure of the device without the possibility of restoring it. If you have problems with the display, it is better to take your smartphone to a service center and entrust the restoration procedure to specialists.

And finally

So we figured out why a smartphone may suddenly stop turning on and how to make it work again. If you found our advice worthy of attention, share this information with your friends and acquaintances. In addition, if you still have questions about this topic, you can ask them in the comments.

Finally, we will give a few universal advice, compliance with which will significantly delay the occurrence of problems with turning on the phone.

• Try to avoid dropping your smartphone on a hard surface.
