The tablet does not turn on what's the matter. Android phone does not turn on further logo (does not want to load)

Yesterday everything was fine, and today the tablet does not turn on. What to do? How to eliminate trouble and return the device working condition? We will try to do it together so that you do not have to go to the workshop.

What are the main causes of breakage?

"Iron".

"Software".

"Iron" are related to the fact that the device cannot be included due to breakdown of cables, battery malfunctions, problems with motherboard or other details of the device. An ordinary user eliminate such breakdowns is difficult: technical knowledge, special tools and spare parts are required here. And independent disassembly of the device can lead to "combustion" issued to you guarantees. Further repair will need to do at its own expense.

"Software" are associated with the established software And software: not quite a good update, hardware failure, virus and others. Many users can deal with such failures. But before eliminating the problem, it is still worth dealing with its reason.

We will try to figure out why the tablet does not turn on, explore all the symptoms and eliminate the fault.

1. The tablet refuses to start due to the battery

Remember when you are in last time Charged a device. Perhaps the device does not turn on, because there is not enough battery charge. If a complete discharge happened, even after connecting to the power source, the device will not be turned on (it is necessary for the battery to accumulate charge). If after 15 minutes of charging, turn on the device failed, "digging" further in search of the cause of the fault.

2. Charging the gadget does not work

You put your device for charging, and after a couple of hours it was discovered it off? Perhaps the memory was moved, and the gadget simply did not have time to accumulate charge. To check the performance, connect other tablets and evaluate the result. Often charging devices burn out.

3. Damage caused failures in

Cracks, dents, strange divorces ("web" or bands) - the reasons for the fact that you are important to pay attention to the repair. Perhaps after the fall of the tablet there was a serious failure, to eliminate which will have to go to those skilled in the workshop.

4. Video adapter of the Gadget "Flying"

You will not be able to run the device to work. To solve the problem with a defective video adapter, you need to go to the workshop.

What if the tablet is turned on, but slows down and hangs when loading?

To say that the tablet does not turn on, it is impossible. After pressing the POWER button, the backlight lights up, the usual appears on the screensaver download Android... and that's it! The device does not turn on. The reasons for the occurrence of such a problem. Among them:

Installed programs. You may have installed or deleted programs. Applications, but there was some kind of failure. As a result, this led to the "krash" of the system and failures in its performance.

Launched malicious applications, viruses, "cracked" programs.

Completed forcibly processes. You have completed the processes that were responsible for the operation of the system. Failure happened to eliminate which you need to click on the RESET button (for its activation on most devices, a needle is needed or a ballpoint pen).

Each user is experiencing strange feelings when the tablet does not turn on. It may be a light panic from breakdown and the possible loss of documents, fear for perfect purchase, hysteria from misunderstanding the cause of the problem. Your task is to calm the feelings and abandon spontaneous solutions (especially if this device is under warranty). Do not deal with independent experiments capable of leading the final output of the device.

You are reading this article due to the fact that you cannot start your tablet. The causes of faults can be a lot, they can be both hardware and software. But this article is not devoted to this. Why the tablet does not turn on and how to reanimate it, we will consider in this article more.

Method 1. Check Z.ancade device

In order to check charger It is easier to use a multimeter. The tablet must produce 5, 9 or 12 volts. If there is no multimeter, then ask someone a charger with the same connector as on your tablet, but be careful that the volatile charging is the same. Enough Charger often fails. In most cases, this happens tochinese models of tablets. If charging cord has USB connector – you can also try Charge it through the computer. It should be borne in mind that the cable itself may be damaged. It is better to first ring the cable or replace it with a well-good job.

You can make it a couple of times, just p try out this when connected m Charger. If a The tablet is not included in these cases, then you need to find a small hole on the tablet with the following Reset. With the help of toothpick or other similar subjectpress the button.

Method 3. Hard Reset.

If after the reboot does not happen, it was damaged by bootloader. Bootloader- this is a loader that controls the kernel. operating system To load the tablet in normal mode. Then the Hard Reset should help. perform further action Remove the SIM card and memory card from the tablet. To perform, you need to hold the power button and the volume rocker down (depending on the model of your devices). Run The menu in which you want to select SETTINGS, then Format System.

Method 4. Slit power button

The tablet may not be included due to the broken power button. To the AC rule, the button has a characteristic click and must be returned to the place after clicking. If this does not happen, you need to check it with a multimeter. Most likely there are 4 contacts, you can tryrepate button.

Method 5. Read B.atareans

You need to disassemble the tablet, turn off the loop or power connector of the battery and connect the power supply to it. Next need take advantage of the multimeter And check the outlet voltage from the battery.

If you have a 3,7 volt battery (charging 5 volts), the voltage must be within 3.9-4.2 volts;

If you have a 7.4 volt battery (charging 9 volts), the voltage must be within 7.9-8.2 volts;

If you have a reinforced 7.4 volt battery (charging 12 volts), the voltage must be within 7.9-12.2 volts.

If the voltage below it means the battery failed.

Now we'll understand why your phone android does not load on the logo (does not turn on after the manufacturer or robot screensaver). Further in the text: first about the reasons and then decryption what to do in one way or another.

This article is suitable for all brands producing phones on Android 10/9/8/7: Samsung, HTC, Lenovo, LG, Sony, Zte, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

Attention! You can ask your question by a specialist at the end of the article.

If you divide all the reasons why your phone on Android hangs on the logo screensaver and does not load further, then this will be

errors in software (it is possible to eliminate yourself);
problems with "hardware" (only in the service center).

Causes of breakage and why turn on, but not loaded

⭐️⭐️⭐️⭐️⭐️ If Android is not loaded on the phone or tablet when turned on, or the smartphone on Android starts, but does not go further the logo screensaver, then the reasons for this may be the following:

Errors when firmware device. These include installing inappropriate or damaged assembly, violation of the firmware order, power failure, and other factors.
Lack of memory. The system may not be launched or due to lack of memory. The solution can also be deleting unnecessary data.
Incompatibility with memory card. If the smartphone turns on, but not loaded to the end, try learning the memory card and try again to start the system.
Hardware problems arising after impact, fall, fluid contacts, effects of extreme temperature.
Damage to the power button or its plume, which "closes" the phone and it goes into a cyclic reboot by loading to the logo and then in a circle. With such faced periodically and diagnose only in the service center.

Before trying to eliminate the problem in the work of Android, it is necessary to understand why the system is not loaded.

Restoration of workability

If the phone shows that the charge goes, then the causes of the problem must be sought in the work of Launcher Android. If the device vibrates, or it flashes the screen, that is, the probability that the screen is damaged.

If you have determined that the problem has a software character (for example, the problem arose after the firmware update), then the simple reboot does not help here. You must dump the system via Recovery Mode or reflash the device. Let's see what to do:

Holding the power button and the volume reduction key (there may be other combination, look for your model), go to Recovery Mode. If the phone means problems are on a deeper level, so you need to contact the service center.
Reset to factory settings by selecting "Wipe Data Factory".
Select "Reset" to restart the device.

Personal data and user settings will be deleted. If this method does not help, perform flashing. To do this, throw the file with a suitable firmware to the root of the memory card, insert the drive to the phone and select the Install Zip from Sdcard in the Recovery Mode.

Increase

You can cope with the software selection yourself, but how to fix hardware problems? The most reasonable option is to contact the service center for diagnostics and repair.

Removing information from Android disabled

Even if the problem can be solved without financial investments, the usual flashing, users arise an important question - how to save the data that is stored in the phone's memory. There is no problem with the memory card: you just need to pull it out of the device. But how to save the data from the internal drive? For example, pull out contacts.

Increase

If you did backup The system or at least, then get the contacts will be very simple. You just go to the "Contacts" app on Google to see full list synchronized contacts. If you want to transfer them to another device, it will be enough to add a Google account on it.

In this case, put for a couple of hours. Then, hold the Off 15 second button (or press Reset). Wait min 15 until the tablet case cools down (the back cover can be warm when charging). Now try to enable (3-5 seconds button ON) and wait 2 minutes.

Please accept my condolences, because if you read this article - it means your android tablet has ceased to turn on. Reasons may be "iron" and "software". The first reason lies in physical disability due to damage to the battery, boards, cables. The second is someone who has slipped the OS Operation on the tablet, and because of the fact that she was crooked after, or some freshly installed prog turned out to be extremely incompetent, the device cannot "start."

The tablet does not turn on at all

1. Remember when the last time was charged your email. One of the most common reasons - tablet fully discharged. In this case, even if you put it for charging, there must be some time (sometimes up to 10 minutes) when the tablet will have enough power to turn on. Sit near the patient, and with a break in one minute, clamp the power button for a long time until the screen is lit. And yes, you must be sure that the charger is working. If there are no changes, check on another device, whether the charger works, or change it. If you are interested, then you need another article.

2. Remember, maybe you gave the tablet to the child? Perhaps the baby started off the screen about the corner of the crib, and damaged the display. In this case, the tablet itself can work, but the screen will have to be replaced. The same situation, if the tablet with landed from one and a half meter height on asphalt, or tiled floor. Yours alone you can do not help him - you can only sympathize with the poor fellow. Usually, mechanical visible defects are evidenced by the damaged screen, or the absence of an image when turned on (only backlight can be visible instead, and it is not always).

3. The tablet did not fall, did not hit, but there is no image? Unlikely, but still: it may have come a drift by a video adapter.

If you still have a guarantee on your tablet, then it is foolish to repair it yourself. Carry to the service center and do not worry. Of course, you can download the schemes on the Internet and try to fix it yourself or give a friend, but it is better not to do.

Tablet turns on only half

In all guilty software failure, and only he. In such cases, we observe the inclusion of the display backlight, and then endless loading (Android is constantly overflow), or see the image with a broken green robot.

This may be a consequence:

1. Incorrectly installed or crookedly operating games, programs, launcher.

2. Forcedly completed system processes ensuring the stability of the operation of the OS. This easily may happen if you "killed" the system process through some kind of manager (or dispatcher) tasks, or third-party program "Battery Save". Believe me, I had one once.

What can be done in such a situation?

There is a chance to "revive" the tablet, dropping its settings to the factory. It is done using hard-cutting, and it is better to google as it is done specifically for your model. Especially if you have a tablet from chinese manufacturer. I highly recommend you to familiarize yourself with the instructions for Hard Reset on various devices. Briefly describe general principleMost likely you will need to do too:

Turn off the tablet
Get the memory card and SIM card (just in case)
Press the volume key ( and some of this decrease!) And the inclusion button 10 seconds is approximately the time is also not the same for all tablets.
The tablet must jib
The menu appears. Select the volume keys and turn on the item Settings. Further - Format System
Choose RESET Android , tablet reboot
All data and settings that were in the memory of the device will erase and return to the factory
Do not be afraid if you do not work the first time, mainly it turns out from the second :)

If a this instruction It did not help, try to use the Council on Hard Reset from the commentator Dima in the article, the Council itself can not be found in the comments, I added it to the article. Also return the device to life helps. And how to restore the tablet after unsuccessful firmware is written.

Just in case, English-language video instruction on hard rezet for tablet Acer. Iconia tab. A500:

If there is a lying android with a red exclamation mark

In many, I noticed in the comments, everything ends as in the picture, or like that:

This is the mode of stock recovery (if you wonder what it is), and there is nothing bad in it and they are not afraid of him. Moreover, you can - ClockworkMod Recovery. If you see it - it means it works - and this is good. You got into it because they introduced an irregular combination for a hard reset, and I warned that it was not the same for all tablets. In this situation, you can click and hold the power button until the tablet does not turn off and try again, or just wait 5 minutes until it turns off and repeat the process. Try again, on the extreme case you can simply reflash.

FastBoot mode

Sometimes sometimes when trying to find a faithful combination, users get into the FastBoot Mode. In such a situation, we see the underlying "Android" open belly / belly, but without exclamation mark. An example of such a menu at Nexus 7 (2013) in the photo:

If you hit here, select the volume buttons item Restart Bootloader. And click on, confirming the selection. Perhaps it will help you download the tablet inclemented earlier.

In general, it is useless to advise something specific, since each model has its own pens. Some tablet models need just to press the "Home" button if there is a lying Android with an open belly - and it will seem the menu in which you can choose a reset of settings. And for some - at the same time click on the increase and decrease in volume. And wait.

It is very unpleasant when the tablet has ceased to turn on. This can occur in a number of reasons. For example, due to malfunctions with iron or software. Sometimes the device stops working after falling. In any case, you need to carefully and slowly explore the behavior of the device. This will determine whether to independently eliminate the problem or better attribute the tablet to the service center.

It often happens that the tablet turned off and does not turn on, although it has been working fine before that, and no system settings or system settings were made. In this case, the problem must be sought in the feed subsystem.

Zero charge

Perhaps the mobile helper simply discharged and does not turn on. In this case, it is enough to connect it to the adapter to the outlet. The device will react to the flow of voltage not immediately. Depending on the model and the level of charge to activate can pass up to 10 minutesuntil the indicator appears on the display.

If the device does not provide signs of life for half an hour, it is necessary to turn it off from the network and thoroughly check the status of contact groups at the adapter attachment site. Possible situations:

oxides are present on contacts a large number of mud;
in the connectors hit foreign garbage;
contact groups are closed by conductive material, for example, a piece of foil from a pack of cigarettes or chocolates.

All connectors and contacts need clear thoroughly. Do it better after the battery is disconnected from the system. In the tablets of solid brands, such as Samsung, Lenovo, Huawei or Asus, make such an operation simply. Most likely, the device is installed a removable battery, access to which opens after removing the back cover. In the products of a lower class, such as prestigio, Irbis, Digma, the battery can be soldered or connected to the cable directly to system board.

After the contacts are cleaned, it is worth checking the operation of the charging adapter on any other device, with the same interface format. By connecting the tablet to the network, even in the absence of external signs of charging, it is worth wait at least two hours. If the device heated - let it cool completely. Then try to launch the tablet.

Battery recycling

If the tablet does not turn on after complete discharge and long lying on the shelf, the battery is most likely occurred. Depends on the model of the device if it is possible revive by regular methods.For example, if the IRBIS tablet turned off, which does not control the residual charge, will have to carry it into the service.

To correct the situation with the recyclable battery, you need:

for Lenovo tablets, Samsung, Asus and others with a removable battery - remove it and charge on a special high current device;
for devices where the battery is attached directly to the system board - contact the service or a fairly qualified private workshop.

In difficult cases, initiating the charging process or "push" the battery may be impossible, the battery will have to change. For brand tablets Huawei, Lenovo and others, you can immediately order the desired type of battery. IN chinese devices From unknown manufacturers it is worth removing the lid and read the label on the battery to buy it in the online store and repair the tablet.

Battery output

Lithium-ion or lithium Polymer Akb have a shelf life. If the battery is constantly discharged below 10% or operates in improper conditions, it ceases to issue currents needed for starting operations in the tablet hardware. Usually, the battery is exhausted. You can check this fact, open the case of the device.

If the battery has clearly visible signs of deformation - this is the reason why the tablet does not turn on. Because of this, other troubles may occur. For example, the tablet is turned on and immediately turned off. Out of the situation only one: the battery needs to be changed.

Memory problems

The tablet has two types of memory: operational and constant. In the latter, all data of the operating system and user programs are stored. If a the device is overheated, There may be a situation with damage to individual storage chips. It manifests itself in different ways. For example, the tablet is dependent when you turn on or refused to work after installing the standard operating system updates.

Important! The clearest sign of damage to the permanent memory looks like repeated cases of load failure. Usually, start the tablet does not manage: it starts to hang on the start of the android or overload cyclically.

Do nothing in this case. If the tablet has a way out suddenly, it is cyclically rebooted, stopped working after the system's harmless update - it is recommended to contact the service center. A similar problem with incorrect work of the flash memory may occur after a decrease in the device or a long exposure to a strong vibration, shaking.

Physical Hardware Damage

Children constantly drag the tablet with them and often drop it. A broken tablet screen can create an impression that the device does not turn on. Visually the device does not respond to the buttons. Wherein the screen illumination slightly burns. In case the device dropped, you should immediately contact the service. In addition to the broken display, when you hit, the operation of other parts of the hardware platform may be disturbed.

On a note! If only the sensor does not work after the fall, then it can be changed with your own hands.

Tip! People having some skills can conduct primary checks. After a fall, if the hardware is turned off, it is worth checking the status of the signal loops. To do this, open the case and check the density of their installation in the corresponding connectors.

If the screen on the tablet went out and does not turn on, and at the same time with the charging and condition of the battery, the contacts are all in order - most likely we are talking about video adapter output. Most often this is due to overheating. To eliminate malfunction, qualified help will be required. If the warranty on the device is not over, it should be attributed to the service. Otherwise, search for a private workshop according to the work of its specialists.

Software problems

Mounted recent programs or system services failure may be the reason that the tablet is charging, but does not turn on. In such a difficult case, you will have to lose all settings and applications. If you configured synchronization services, it is not difficult to restore key data.

Usually, when problems with software, only the name is on when you turn on the tablet or it hangs on the screensaver when turned on. It shows what to do system reset . This will restore the settings of the Android to the state they had when the product is released from the manufacturer. On different devices, the operation is performed in a certain way.

Before reset, you need to pull out all the memory cards and SIM mobile operators from the device.
Tablets of solid brands (Samsung, Asus, Lenovo, Huaway) do not have a physical reset button. System formatting is produced through the loader menu. To go to it, pin the volume up and power button. After some pause, the tablet will enter the Recovery Mode. In the menu that appears, you need to select Format System, then Wipe Data / Factory Reset.
In low-cost devices, such as Irbis, Digma, Prestigio, have physical button Reset. For its pressing will need a thin clip. It is necessary, referring to the instruction, find the hole of the reset and press the button located behind it for 5-15 seconds.

Another way how to enable the tablet, if it does not turn on after the software failure - log in to the quick download menu. Usually, on the screen, the robot android on the back with an open hatch on the stomach. Using the volume buttons, you need to select the RESTART BOOTLOADER menu item. The key combination or key sequence for a particular tablet model is worth searching on the Internet, the manufacturer in the documentation usually does not provide such data.

Conclusion

Deciding what to do if the tablet does not turn on, it is only after some observation of the device's reactions. For example, you should not panic when the device refuses to work immediately after connecting to network adapter. If the tablet flashes and does not turn on when charging, this means that the battery capacity lacks to activate the hardware platform. The device needs to give more time.
