It turns on. Why doesn't the phone turn on? Mechanical damage and moisture ingress

Modern smartphones are complex and quite delicate devices. One “fine” morning, you may find that the gadget that was put on charge refuses to work. Today we will figure out what to do if the phone does not turn on or boot, and also how you can fix this problem at home.

There are not many answers to the question of why the phone does not turn on, what could be the reason for its rapid discharge and what to do in such a situation. Let's look at the most common options and solutions.

Adapter faulty or missing contact

The most common reason why a phone won't boot or runs out of charge quickly is a faulty charger. To verify this, you need to connect the gadget to another power supply. If it starts charging, then you have found the reason and the problem was in the charger. You can do the opposite, connect a known good phone to a suspicious power supply. Thus, you are guaranteed to ensure that it is faulty.

If the smartphone does not charge from a working power supply, check the contact connector. It may become clogged with dust or pet hair. Carefully clean the connection socket on the phone with a wooden or plastic toothpick and try again.

If your phone has a removable battery, check the tightness of the contacts and their condition. There is a possibility that they were oxidized by moisture or bent when the battery was inserted after being dropped.

Another opportunity to “revive” the battery or make sure it is in good condition is to use a universal charger. In common parlance it is called a “frog” and is capable of charging any removable battery from a household electrical outlet.

SD card

One of the reasons why an Android phone does not turn on is the use of an SD card with a larger capacity than stated by the manufacturer. The desire to experiment is in the blood of users. If the specification says that you can only use 32 GB, you will definitely try 64. With a high degree of probability, the device will recognize the card. It will work normally until the recorded amount of information exceeds that declared for support.

If, after a software failure, the phone stops turning on or does not boot, just remove the problematic memory card from it. A forced reboot will bring the smartphone into working condition.

System errors and failed updates

System errors, or a resource-intensive application that is not completely unloaded from RAM, can cause the battery to begin to rapidly discharge, causing the phone to turn off and not start again. It can behave similarly malware. The virus, if its task is not extortion, works in the background. At the same time, he tries to use all available resources as quickly as possible. If your Android phone runs out of battery faster than usual while in standby mode, you should check it for infection and force a reboot. Further actions depend on the results of the anti-virus scan.

If the smartphone is clean and charged normally, there is no reason to worry. Otherwise, if the device does not start or the phone is quickly discharged again, you will need to full reset and re-tuning.

An unsuccessful software update can result in the phone not responding to user actions or simply turning off. Usually, this behavior is easily “cured” by rebooting.

In case of failure when flashing the firmware on new version OS, the situation is a little more complicated. When the phone starts, but the boot does not go beyond the splash screen, the recovery mode can save the situation. It is best to find out what to do and how to enable Recovery Mode for a specific phone on the manufacturer’s website or in the documentation for the device. When this is not possible, try universal methods. The vast majority of Android smartphones support turning it on by holding down the power and volume keys. Whether it is an Up or Down button depends on the device manufacturer. You can try both options sequentially.

Hidden defects

Some users believe that physical damage occurs when the phone falls on a hard surface and shatters. Before that moment, he also fell twice, but only “slightly” scratched and crumpled. Meanwhile, we cannot rule out the appearance of hidden defects from impact on the gadget’s body. Damage to internal contacts will result in the Android phone not turning on or charging, or sometimes working and suddenly turning off. So if your phone falls, it is impossible to fix the motherboard malfunction on your own and you will have to contact specialists for a full diagnosis and possible replacement of components.

Finally

If the phone does not turn on even after you have gone through everything probable reasons, you should contact the service center. By not being too proactive in trying to revive him, you will save yourself time and nerves for specialists.

Despite high level With the development of technology, modern gadgets are still far from perfect. After all, new devices often malfunction and fail. For example, probably everyone has encountered the fact that a mobile phone simply does not want to turn on. At the same time, many do not know what to do to correct the situation. If you belong to this category of people, then read the article. It will talk about what to do if your mobile phone does not turn on.

First you need to determine why your mobile phone does not turn on. To do this, you need to diagnose the device. It is worth noting that it is quite difficult to determine the cause of the malfunction. But if you succeed, then in most cases you can repair the device without any problems. So, let's look at the main reasons why it won't turn on. Graphics tablet or telephone.

Lack of power

It's no secret that the phone is powered by a battery. Without a battery, the gadget will not even be able to start. If your phone or tablet does not turn on, then first of all you need to check the power source. Perhaps the device is simply discharged. Connect it to the charger and try turning it on. There is no effect and the charge does not flow? In this case, the failure was caused by one of the following reasons:

As you can see, if the phone does not turn on and does not charge, then in most cases the problem can be solved on your own. To avoid battery problems, do not use your smartphone while charging and try to charge the device to the end.

Memory card

A regular memory card can cause problems with activating a smartphone. For example, if you insert an SD card that your mobile phone does not support, this will most likely lead to software failures. Because of this, the smartphone may not turn on.

Fortunately, fixing the problem is very simple. You need to remove the memory card from the mobile phone and try to turn it on again. This usually helps. If the device still does not show signs of life, then you will have to reflash the device. To avoid such software failures In the future, always read the instructions, which tell you which cards are supported by your smartphone.

Software failure during software update

Sometimes after the official firmware the phone does not turn on due to a software glitch. In this case, it is necessary to perform a reset procedure to factory settings. This is done using the so-called Recovery Mode. How to use it? Read the following instructions:

If the smartphone does not respond to the Recovery Mode call, then most likely this model has a special button for rolling back. As a rule, it is located near the SD card slot. You can press the reset button using a regular needle or toothpick.

Phone damage

Usually the phone doesn't just stop working. As a rule, various damages contribute to this. For example, the phone fell into water and does not turn on. What to do in such a situation? First of all, you need to remove the battery, wipe it and not use it for at least a day. Try placing the parts in dry rice. After this, you need to let the phone dry. This may take several days. However, it is not at all a fact that after drying the smartphone will work. Yes, there is no longer any water in the device, but salts remain inside, which corrode the radioelements during operation. If the mobile phone still does not work after drying, then you need to contact the service center.

Another common problem with falls is screen breakage. The phone may be functioning, but it is difficult to understand due to the broken display. How to determine if a mobile phone is working? Press the power button and listen to the speaker. If the device starts up, it will start making sounds.

Perhaps a broken display is the worst of the above-described outcomes. Repairing the screen at home without the appropriate knowledge and skills will not work. The only option is to go to a service center. Nevertheless? This decision is unlikely to please you. After all, replacing a screen is quite expensive. Sometimes it's cheaper to buy a new phone.

Conclusion

If the smartphone does not show any signs of life, then do not panic. Diagnose your device using this article. If you can determine the cause of the breakdown, then most likely you can easily solve the problem. As you can understand from what is written in this article, situations when you need to take your phone to a service center arise quite rarely. Usually, problems with turning on arise due to some harmless problems that can be solved at home.

Modern gadgets are complex devices that, due to their design features, have some problems. One of the common problems is the situation when the phone does not turn on, but responds to charging. This applies to both Android devices and iOS devices.

The smartphone does not turn on after the owner puts it on charge, but it shows how many percent the gadget is charged. However, after disconnecting from the power supply, it fades away again. In this case, you need to decide what to do if the phone behaves this way.

Mechanical damage

A distinctive feature of smartphones is not only their performance, but also their fragility. When a phone falls even from a height of human height, it causes breakdowns of various levels. In some cases, the gadget stops working altogether, and in others it turns on when the charger is connected.

The biggest problem in this case is the difficulty of identifying the breakdown. Perhaps the shock affected only the battery, which should be replaced; in other cases, the contact of the power button is broken. To fix the problem, it is best to contact a specialist who can find the damaged element.

Hardware failures

In some cases, the cause is burnout or breakdown of electronic boards or individual elements. Like any other technically complex product, a smartphone may experience a breakdown of the screen, processor or any other part. To solve this problem, you need to contact a specialist who will disassemble the device, find the damaged element and replace it with a working one.

Excessive efforts to replace the system board will probably result in the impossibility of further repair of the equipment. To receive qualified assistance, you need to pay attention only to official diagnostic centers that are responsible for the work performed.

Stuck memory card

Sometimes it is enough to remove the SD or microSD card from the slot for the system to boot. Mostly Samsung and Lenovo suffer from these problems. Be sure to try this method!

Accordingly, this is not applicable for Apple devices, since they do not have the ability to remove external memory.

Software failures

Failed system updates are especially common on Andriod. In this case, the owner will not be informed about the need for an update, since it is often carried out offline, unless canceled in the settings.

If, after installing the updated software, the startup process does not start, you can try to remove the battery and reinsert it. You can repeat the procedure several times. Sometimes this method can bring the device into working condition.

If the Andriod icon freezes on the screen during startup, then you should press the Reset button, which can only be accessed by using a needle or toothpick.

Firmware error

If the problem arose after third-party intervention in the smartphone’s firmware, then it is recommended to return the smartphone to the basic settings. To do this, you will need to enter Recovery Mode; to do this, you need to press three buttons together, observing the order:

• "Increase volume";
• "Home";
• "Inclusion".

Next, a short menu will open where the user must select “Wipe data/factory reset” and confirm the choice with the item “Yes – delete all user data”. There is a group of people for whom this method may not be suitable, since all personal data will be erased.

If you have important information, you should contact the service center, where you must indicate that restoring functionality should not damage existing files.

One of the options for saving files would be to copy them to another medium, after which the system will restart, which the employee must inform about.

Phone memory completely full

If the internal memory is completely full, this can not only worsen the speed at which the device turns on, but also completely put it out of working order. One way to easily correct the situation may be to use an external memory card.

If the device does not support the use of SD cards, then you can connect the smartphone to the computer and transfer files (video, photos, audio, etc.) to the PC. If after this the device still does not turn on or the process takes too long, then you can use programs that clear the cache memory of gadgets, for example, CCleaner or Clean Master.

Couldn't diagnose the problem

If the user was unable to independently diagnose the problem, then he should contact a service center. You should not reflash the device yourself, as such actions can lead to a “bricked” cell phone.

In some cases, diagnosis is impossible even by specialists. If a person is faced with such a situation, then he can try to go to another service. If the fact that repair is impossible is confirmed, then you will have to purchase a new gadget.

Conclusion

In order to avoid getting into a similar situation in the future, it is recommended to follow a few simple rules:

1. Even careful storage of the gadget will not provide complete confidence that force majeure will not occur. Therefore, important files should also be stored in cloud storage or elsewhere.
2. Not worth installing third party applications, which were not found on Play Market. It is to create a safe environment that the Play Market for Android was created.
3. Cases can not only become a beautiful design solution for decoration, but also protect against minor impacts.

If the device still malfunctions, then do not despair. You just need to take the gadget to a specialist. The wizard uses flashing and resetting the settings in extremely rare cases.

Why doesn't the phone turn on? In modern life without it mobile device very difficult to get by. And it fails at the most inopportune moment. And regardless of the manufacturer. Any device may not turn on. I don't feel like buying a new cell phone. This device is not old yet. Yes, and it costs a lot. Let's find out why the phone won't turn on. And what to do with it?

Research the problem

Let's consider several options for this situation.

Cell phone does not turn on after turning off

1) The battery is completely discharged.

Perhaps you haven't needed your mobile friend for a while. Accordingly, he was not “fed” in any way. Not a single mobile phone will turn on in such a situation. Even if it is fully operational.

How to proceed?

Put it on charge. Best for a day. But half an hour is enough to turn on a working device.

2) The battery contact has come loose.

Accidentally hit and dropped my cell phone. Not much, but the battery moved. Her contact with the device was broken.

How to proceed?

Remove the back cover of the mobile phone, remove the battery and insert it again, pressing it firmly to the place where the phone contact is located. Try turning it on again. If the problem persists, press the battery with your fingers and turn on the cell phone again. Turned on? Then you need to fix the battery in this position. A piece of cardboard cut to the size of the battery is suitable for this purpose. Place the cardboard on the battery and secure it with the back cover of the phone. If you haven't turned on, read on.

3) The battery has outlived its useful life.

What to do if your phone won't charge? Each battery has a limited life. If your cell phone is more than three years old and is not charging, insert a new battery. It can be purchased at any communication store.

How to proceed?

In principle, we have already answered this question. Change the battery.

4) The gadget took a swim or hit the wall hard.

Anything can happen. Stretch your memory: have similar incidents happened to your mobile phone? The incident could have happened a week or two ago. And the cell phone responded only now.

How to proceed?

There's no point in digging around on your own. The gadget needs the help of specialists. Take it to a service center for diagnostics. Professionals will assess the level of the problem. If the device can be saved, it will be saved.

5) The memory card is faulty.

If there is one, of course. Viruses imported from another device after downloading a new game, mechanical damage to the card - all this can cause the phone not to turn on.

How to proceed?

Take out the memory card and turn on your mobile phone. If it turns on, you will have to change the card.

6) Software failure, chip failure.

In such situations, it is better to immediately go to the service center. Without special knowledge you will not do anything.

7) The power button is broken.

For a long time it endured sharp pressure, moisture got in, the phone hit, etc.

How to proceed?

Carefully inspect the phone's on/off button. Try pressing it and holding it for ten seconds. Explore it appearance. Look to see if the button is tight or if there is a click when pressed. If the reason is the key, then it needs to be replaced at a repair shop.

The mobile turns on and immediately turns off

1. Mechanical and physical damage. It is after falls and swimming that the phone begins to act up. Some internal elements have become unusable. And only diagnostics will help you find out more accurately.

2. Battery capacity has decreased. There is no longer enough charge to keep the phone on. But the first warning signs appear earlier. Most likely, you simply ignored them. When the battery life decreases, the phone turns off during a call. It is during calls and calls that the greatest charge consumption occurs.

Sudden shutdowns of mobile phones also lead to

• program crashes;
• malfunction of microcircuits, boards and contacts;
• unsuccessful firmware and flashing;
• use of low-quality (read: unlicensed) software products.

Problems may also arise after updating programs. The phone shows that "Update is complete" but does not respond to button presses. In this case, disconnect all wires, remove the cover, and remove the battery. Re-insert it. And try turning on your mobile phone. It should work.

If your phone does not turn on, this can make any user nervous, but in any case, before taking the device to a service center, you can try to provide first aid to resuscitate the smartphone. Problems due to which the phone does not turn on can be either software, for example, a problem with the firmware due to an unsuccessful update, or hardware, for example, due to a failed battery.

Below we have tried to put together a lot of tips that will help you figure out why your phone won't turn on. If none of the tips helped you, please describe your problem in the comments.

The phone does not turn on after repair.

If you decide to disassemble the phone yourself, and after assembly it does not turn on, then the problem may be that you simply forgot to connect power to the motherboard of your device. You must disassemble it again and make sure that the power supply circuit from the battery to the motherboard is not broken and all cables are in place. If you have a multimeter, try checking the voltage on the battery, or after assembling the phone, try putting it on charge. Almost all phones notify you when charging starts, even if the device is turned off.

What to do if water gets into your smartphone

Let's look at the hardware reasons why the smartphone won't turn on.
One of the reasons may be falling into water. What to do if your phone falls into water? First, remove the battery, you need to do this as quickly as possible, then dry your smartphone with a hairdryer. Control the air; it should not be hot, otherwise the touch glass and some other components will simply begin to peel off. Then, without inserting the battery into the smartphone, put it in a warm place. It is worth noting that you do not have much chance of salvation and it may not be possible without losses. In particular, the buttons on the device may stop working. If you have dried your smartphone, but it does not turn on, it needs repair at a service center. The worst thing that can happen is replacing the system board, which, by the way, It costs as much as a smartphone itself.

The smartphone does not turn on after being completely discharged.

This problem is observed in some modern smartphones. In particular Sony phones. Some Sony phones had such a feature that it was impossible to turn them on after being completely discharged if the phone was in this state for a long time. One thing helps - long-term charging of the battery with a current of 2A. And these are almost all chargers.

In any case, as I already wrote above, you need to put your smartphone on charge for several hours. Usually the problem goes away on its own. You can also try Charger with a higher current strength, for example, 1.5 or 2 Amperes.

Also try making your smartphone.

Check the battery. The phone may not turn on due to a faulty battery.

This is a must. If you have a removable battery and can install another one, do so. Sometimes, although not often, the problem that prevents your smartphone from turning on may be the battery. By the way, is your battery fully charged? Maybe this is the case?

With some phones, especially if the phone is several years old, the actual battery charge may not match what your phone shows. If your phone won't turn on, try charging it for a few hours. It is possible that the battery will charge and the phone will turn on.

The battery wears out very quickly. Many manufacturers mobile phones They give a one-year warranty on the device itself, and half a year on the battery. The reason for battery failure is quite simple - a very heavy load on it. We constantly charge our phone, and as you know, batteries lose their charge with each charge-discharge cycle. For example, standard lithium-ion batteries installed in our phones work properly under load for no more than two and a half years.

Check the charger.

If your smartphone is dead and it won’t turn on again, maybe it’s a charging issue? Try charging your device from your computer. If the phone shows no signs of life within half an hour, the problem is not with the charger. If the phone seems to be charging, but cannot charge, check the charger on another phone. It is quite possible that it will need to be replaced with a new one.

The phone does not turn on after being dropped. Mechanical damage.

Smartphone manufacturers like to say that their phones cannot be scratched, drowned or broken. Manufacturers give their phones Gorilla Glass screen protection, IP67 water resistance, shockproof casing, and so on. Despite all the phone protection measures taken by companies, it often happens that the phone does not turn on after being dropped. For example, on asphalt or falling into water. Unfortunately, all that can be done at home after a fall is to see if the battery, power cable or display cable has come loose, if there is a sound or vibration signal to turn it on.

Do something more with dropped phone It's unlikely to work at home. To do this, you need to check the voltage on the battery and on the system board. If your phone is dropped and won’t turn on, and you don’t have the necessary tools at home, you will have to take the phone to a service center.

After the firmware the phone does not turn on.

One of the most common reasons why a phone may not turn on is due to an incorrectly installed firmware or update. After flashing or updating the phone does not turn on due to incorrect installation of files. In this case, you will need to flash the phone. For example, if your samsung phone, then you will need to download the firmware from the official Samsung website and the Odin flasher program. Using this program you can flash your phone. All settings and files on your internal memory, but there is a possibility that the phone will turn on.

If Lenovo phone won't turn on, then in this case you will need to enter Recovery mode by simultaneously pressing the power and volume up keys. In the Recovery menu you will need to select the wipe data/factory reset menu item, and then Yes - delete all user data. Unfortunately, for different phones, go to Recovery menu it can be done in different ways. If you are sure you installed official firmware or an official update, then contact the manufacturer’s authorized service center, they will restore the firmware.

But we recommend you try perform a Hard Reset by resetting the phone to factory settings. Very often this helps if the phone does not turn on. Below we have selected key combinations for popular phones.

Samsung phone won't turn on: Press and hold the volume rocker up, the center menu button and the power button at the same time.

LG phone won't turn on: Press and hold the power button and volume down button at the same time, then select wipe data/factory reset.

Huawei phone won't turn on: Press and hold the Volume Up key and the Power button at the same time. You can try pressing the home button, volume up key and power button.

If your other phone does not turn on after flashing, write the exact model in the comments. We will try to help you.

The phone turns on and turns off immediately, what should I do?

It often happens that after updating or installing a program, your phone turns on and immediately turns off. Usually it looks like this: the phone turns on, the logo appears, the boot process takes place and the phone goes into an eternal reboot or turns off. There can be a lot of problems here, from the firmware to the battery. If you have a problem with your phone after flashing or updating the device, then roll back to the previous firmware or reset the settings. Will help.

Sometimes the phone turns off while the device is booting up. Consider your phone does not turn on and the advice from the previous paragraph will help you. You must perform a HARD RESET or flashing the device using a computer.

If you have not updated the firmware, then the whole issue may be the power button, which “sticks” and turns off the phone. Unfortunately, this happens very often, especially if the phone ends up in water. In almost all smartphones, the button is soldered to the motherboard and can be replaced.

If The phone turns off and turns off immediately after full load when you see the desktop and icons, then try to remove the latter installed programs, if of course there is enough time for this.

The phone may turn off immediately due to the battery. Check the battery and system board cables. Even if a smartphone has a “non-removable” battery, removing it is not that difficult. In any case, if you are sure that the problem is not in the firmware, then you can most likely find out exactly the problem due to which the phone turns on and off immediately at a service center. Again, the problem is either in the firmware or in the power circuit.

These simple steps can help you provide first aid if your smartphone does not turn on. If none of these points suits you, take the device to the store if it is under warranty or to a phone repair service center if it is no longer under warranty.
