So, since you are here, your tablet does not turn on, and there are no acquaintances who can solve this problem or they are very busy. Moreover, you have clearly already tried to do something with him and we will cherish the hope that you did not aggravate the situation.
There are many reasons why the tablet does not work, but this does not mean that without special knowledge you cannot carry out minimal diagnostics. You can very well. And along with this, you also save yourself a n-th amount of money that you would have to pay to the service center. The main thing is to clearly and consistently perform actions that, in turn, will throw back various options.
Hardware or software?
First, we need to understand where the problem initially lies - in the hardware of the tablet or in the software. Because the seriousness of our actions depends on this, and indeed the answer to the question of whether we can reanimate it on our own.
Step 1. We look at the damage
We examine the tablet for an example of mechanical damage. Try to remember if you could have dropped it or hit it somewhere. Perhaps you gave it to someone to play with or just use it. As much as you are not sure that the person treated him carefully, you still should not trust. Many are trite afraid to say.
After examining the tablet, we:
a) Found damage. Even the slightest chip can be a sign of a fall and, as a result, breakage. It happens that there are only a couple of scratches on the case, but inside something took and fell off. No one will advise you to open the tablet, look for circuits and repair the hardware yourself. If only because in 90% of cases this leads to even greater breakdowns. Therefore, the tablet must be carried under warranty, or, if its term has run out, to the workshop.
Well, it's even silly to talk about the version of the broken screen. The reason for the lack of performance is clearly visible.
b) No damage was found. A clean, good tablet, and we remember every scratch and that was a long time ago. So let's go to step 2.
Step 2.11st attempt to enable
We are trying to turn on the tablet. Yes, you have already tried to turn it on and it did not turn on - that's clear. But now we need to carefully watch what happens when we try to turn it on.
Presumptive development options:
Option 1. The tablet starts to boot, but does not turn on completely.
Option 2. The backlight turns on or other signs of the life of our device appear.
Option 3. No signs of life.
Below we will analyze these two options. And let's start with the latter.
Option 2. Backlight only
In this case, there is still the possibility of hardware failure, but it is possible that the matter is simply in the software. Therefore, to begin with, we follow all the recommendations for option 1, and if all else fails, we go to the service.
Option 1. Loads, but not completely
In fact, the most common option. The time when it was difficult to create viruses on phones and tablets is long gone. Moreover, today the operating system on such devices is very complex and absolutely any harmless program can interfere with its work. And of course, no one excludes the option when our Android glitched simply due to an incorrect shutdown. In general, as you understand, there can be a huge number of reasons, but the main thing for us now is to bring our device back to life. So let's move on to the next step.
Step 3.5 Safe Mode
You can try to perform this step if our patient is more alive than dead and simply lags a lot, does not want to load the system and generally hysterics by different methods. Therefore, it is not particularly necessary to highlight it as a separate step. Nevertheless, we try to enter safe mode and restore the operating system. It turns on differently on different versions of Android, so read about that in another article.
Step 4. System restart
First, you have to accept that all your data and settings will be deleted. More precisely, not all, but those that are stored in the main memory of the tablet. Because restarting the system can bring the device to life, or how it would be more correct to call it a hard reset. So that you roughly understand what is happening in this case, you can give an example. Hard reset is about the same as installing the factory OS on a laptop, which is stored in a separate protected partition of a hard disk. Most often it is called recovery.
Make this one hard reset you can from a special menu, which is called by a certain combination of buttons. But as is usually the case, the combinations of buttons on different models are different, and therefore we will give the most frequent ones. Don't be afraid to go over all the options. You certainly won't do any worse. Just do not forget to remove the memory card and SIM card from the tablet, and it is advised to perform all actions with the tablet connected to the charger
The menu (this is something like a BIOS on a computer) is called by simultaneously pressing the following buttons:
1) Volume up, volume down, power button
2) Power button, Return button (Home / Home), Volume up
3) Volume up, power button
4) Volume down, power button
5) Decrease and increase the volume.
Hold for 10 seconds and try each option several times. On the first try it rarely works.
If the menu does not appear, but a picture of the fallen robot appears, you can rejoice. You have not rebooted yet, but the problem is probably in the software, and this can be solved.
We clamp the buttons according to one of the above options and we have:
a) A menu appears. Then we are looking for settings, there formatting the system (Format System) and restarting Android (Reset Android). The control is carried out by the volume control buttons, and the confirmation is carried out by the power button.
b) The menu does not appear. We try again, then other combinations, and when the number of attempts exceeds a reasonable limit, we take it to a specialist. So the problem is more serious.
c) A fallen robot appears. As already mentioned, you can rejoice. We hold down the power button and turn off the tablet. We are waiting for 5 minutes and try another combination. Attention - after hard reset all installed settings and all data will be deleted
... But you get a fully working device.
If the desired combination cannot be found or the hard reset did not help, proceed to the next step.
Any device sooner or later begins to work with failures and errors, the fault is either software (system) failures, or a malfunction of the hardware part of the device. Very often, the tablet may stop working after installing programs from an unreliable source or programs written for another operating system.
One of the most global failures is the inability to load the operating system on the tablet. When you turn on the tablet, the logo of the Android operating system or another may appear, after which the device stops loading, and you can do nothing except turn off the device.
But even such a failure can be fixed. The first thing to do is try to enter the service menu and reset all settings and restore factory settings. In this case, all user data on the internal memory will be destroyed, as well as the installed programs. So, just in case, remove the memory card from the tablet before resetting. Connect your device to the charger. In order to enter the recovery menu, you must press the key combination. This combination is different for each tablet manufacturer and model. Most often, you need to press the Volume (+) or (-) button and hold it down while pressing the Power button. Within a few seconds, a menu with several lines should appear. If this does not happen, it is possible that your tablet is using a different combination of entering the service menu. If possible, you can find on the Internet how to enter the service menu of your tablet model.
After the menu is loaded, go to an item similar to (Wipe Data Factory) (Reset). Navigation in the menu is carried out using the volume buttons. And the confirmation of the choice is carried out by pressing the Power button. Next, we need to confirm our choice, for this we select the line (Yes) and press the power button. A reset will occur and after turning on the tablet will boot as before, all settings will be reset as if you just bought it.
If this method did not help you or you could not enter the reset menu, then you must try to reflash the device. To reflash the device, you need to download the current firmware version that suits your tablet, carefully check the model. For flashing, use the instructions that can be found on the manufacturer's website in the (Support) or (Downloads) section. Next, you must strictly follow the instructions and do not miss anything. It is better to first carefully study the instructions, think over the actions, and only then proceed to the direct firmware.
If it seems to you that you will not be able to cope with such a task, or something has not grown together, then do not worry, anyone will restore the working capacity of your tablet, although you will have to pay for their services.
If the tablet under warranty does not turn on, it must be taken to a service center. Otherwise, you can try to repair it yourself. To do this, you first need to understand the reason that caused the breakdown.
Perhaps the tablet just sat down. Try charging it. Please note that when fully discharged, it must take a while before the device can turn on (even while charging). Sometimes it even reaches 10 minutes. If the connection to the network does not resolve the issue, make sure the charger is working properly (try connecting another one or test this one on another tablet). Remember if the tablet has received any mechanical damage (or check with family members). The impact could damage the display (it must be replaced, after which the tablet will most likely work again). The mechanical damage to the screen can be confirmed by the presence of a backlight when turned on (but this is not necessary). It is also possible that the video adapter has flown - you will have to change it. If the switching on occurs partially (after the backlight, the load is constantly displayed, the image of the broken robot is displayed), a software failure has occurred. This could be due to:- incorrectly installed game, program;
- forced shutdown of the device (the stability of the operating system is violated).
- turn on the tablet;
- remove the SIM card, memory card;
- press the volume button (increase, sometimes - decrease!) simultaneously with the power button;
- hold for some time (most often 10 seconds);
- when the tablet vibrates, select "Settings", "Format System", "Reset Android" from the menu using the volume keys.
Today almost everyone has a tablet. These devices have a large number of functions and are often not inferior in their characteristics to a real PC.
But at the same time, the gadgets in question have some disadvantages. First of all, it is fragility. That is why, after a fall, sometimes the android device simply does not want to turn on. Sometimes it is difficult to fix such problems.
Causes and solutions
There are a very large number of very different reasons why startup difficulties may arise. This is the most difficult part of the repair. But there is a list of the most common malfunctions due to which such precedents arise.
These include:
- breakdowns of a mechanical nature, ingress of moisture;
- battery problems;
- software failure;
- video adapter problems.
Mechanical failure and moisture
If the tablet does not turn on after a strong impact or falling on a tiled, brick floor, then most likely the following damage is present:
Most often, the reason for the lack of response to pressing the Power button lies in the mechanical damage to the screen. Usually, a 1m drop to the floor is sufficient to break the floor. If the screen does not work, then, most likely, it will need to be replaced.
Performing this operation is quite difficult from a purely technical point of view, but at home it is quite possible to carry out it. You just need to be as careful as possible.
Also, the loop that directly connects the screen itself and the computing systems often fails. Sometimes it just comes out of the connector, you just need to open the case and reinstall the connection. Everything is much more complicated if the soldering has disappeared. Such repairs are difficult to do on your own.
If the device falls into the water, then often it subsequently stops working altogether.
When a similar situation occurs, you must perform the following actions:
Battery problem
Often, difficulties with launching gadgets of this type appear due to a battery breakdown.
He can:
Complete failure of the battery is possible if it is used incorrectly. The fault can often be identified visually. If the battery is swollen and does not fit into the case, then it should be replaced. It also often happens that when the battery is fully discharged, the device may not start.
In such situations, it sometimes does not even respond to charging. It is required to leave it connected to the 220 V network for 12 hours.
Software crash
The miniature PC may not start due to a malfunction in the software part.
This occurs in the following cases:
In most cases, troubleshooting of this kind is quite simple. You just need to remove the installed one, if in any way it was still possible to start the device. If the gadget is completely "dead" and does not react to anything, then you can simply perform the HardReset operation. It is a complete reset. Its only drawback is the complete deletion of all data.
Failure of the video adapter
When the launch is performed and all possible actions are carried out (reacts to the "home" button, the sound is added and decreased), but the screen is black - this means that the video adapter is out of order.
Most often, this kind of malfunction occurs due to overheating of the device, as well as a factory defect. It will not be possible to replace the component on your own, in which case it is necessary to take the device for repair.
Tablet won't turn on
Also, sometimes there are situations when the gadget does not start after performing certain actions.
This type of problem often occurs after:
- charging;
- installing new firmware;
- reboot;
- reset settings;
- disconnecting the charger;
- launching a large number of applications.
Various measures should be taken for problems of the type under consideration. They are purely individual in each case.
After charging
Sometimes it happens that the device is charging, but, subsequently, it simply does not work.
In this case, the culprit of the current situation may be:
- Charger;
- accumulator battery.
The first step is to check the charging. You need to connect it to a similar device and observe whether the battery is replenished. If everything is in order, then the matter is most likely in the battery. It may simply not hold a charge. To establish the true cause in this case can only be empirically.
After flashing
Often the reason for the lack of response when you press Power is a flashed firmware. Such problems occur both through the fault of the user and due to incorrect software.
There are two ways to resolve such situations:
- install new firmware;
- perform a Hard Reset.
How to flash a tablet if it won't turn on? This will require:
In most cases, the device does not fully start, but only partially. That is why, by connecting it to a personal computer using a special communication cable, you can perform a flashing. In very many cases, this action will solve the problem of the type in question.
If after flashing the state of affairs has not changed, then you need to perform a HardReset. This operation allows you to reset all settings and delete information installed by applications. This operation is launched in different ways, depending on the gadget model.
For example (pressing buttons at the same time):
- "Turn down the volume" + "turn up the volume" + "turn on";
- "Turn on" + "home" + "increase the volume";
- "Decrease the volume" + "Power".
If necessary, you can easily find a Hard Reset launch key combination for any model of a gadget of the type in question on the Internet.
After reboot
Most of the problems in the device can be resolved with the most common reboot. If such an operation does not affect the operation in any way, then, most likely, the Boot Loader is damaged.
There are two ways to deal with this problem:
- by starting the system formatting - HardReset;
- by flashing the OS.
If these measures did not have any effect, then you should contact an authorized service center. Since, most likely, there were some problems with the hardware.
It is only possible to identify a problem and repair it with special equipment and skills. In a domestic environment, it is extremely problematic for an ordinary user to do this.
After factory reset
Sometimes it is very difficult to determine what the problem is when the tablet won't turn on after a factory reset. But, in most cases, this is not required.
You can simply do a hardware reset. Most of the models are equipped with a dedicated button for this operation. Most often, the key is recessed into the body.
For executionResetthus a long thin rod is required:
- needle;
- clip;
- pin.
When you have a similar item on your hands:
After that, in most cases, the standard parameters and factory settings are loaded, and a restart occurs. Most likely, the gadget will resume its normal operation and will begin to respond to the Power key as expected.
Without charger
Relatively often, the device does not start without a charger connected - which may be the result of battery-related problems. If there is a charge in the corresponding port, the required voltage is created on the contacts and the gadget works without any problems.
After unplugging from the outlet, the electrical current is lost - which is the reason for the shutdown.
This can only be dealt with by replacing the battery. Some models of gadgets of this type allow you to do this without any difficulty on your own. In other cases (iPad and similar equipment), special equipment and skills are required.
Due to lack of memory
Sometimes the gadget may not start to the end. Very often the reason for this is the large number of programs and applications present in the RAM, autorun.
To solve this problem is quite simple - you need to reset all settings to standard, or edit the startup file, removing everything unnecessary from there.

Firmware methods
If after flashing the gadget does not start, then you can deal with this in two ways:
- programmatically;
- hardware.
With software recovery, you will need:
- USB flash drive in FAT32 format;
- fully charged gadgets;
- utility NSBAtchTool.rar.
When everything you need is already there, it is necessary:
When the boot card is ready, you just need to insert it into the gadget, then hold down the Power key for 10-20 seconds. The installation will take place in automatic mode. After completing this process, remove the memory and restart the device.
The tablet turns on and off immediately, what should I do?
Sometimes it happens that Hard Reset and the banal installation of a new firmware simply do not help. You can cope with such a misfortune by closing the flash memory contacts on the motherboard.
To do this, you will need to read the technical documentation or scour the forums in search of the necessary information. These pins may look like legs or just like specks of copper.
The process under consideration is performed as follows:
The gadgets in question are quite capricious and fragile, which is why you should handle them with the utmost care. In most cases, this allows you to avoid a variety of problems, including with normal switching on.
Tablet breakage is one of the most unpleasant situations, especially if you actively use this device in your daily work and feel like you are without hands without it. However, let's not despair and fall into hysterics. Since you have visited the site, it means that you are interested in solving the problem yourself. Well, let's try to revive your tablet, even if it won't turn on or show minimal signs of life.
Your main task is to conduct a thorough diagnosis and understand why the tablet does not turn on. In principle, there are not so many reasons for this, they can be divided into two separate groups: software and hardware faults.
The model of the device based on the Android OS is not of fundamental importance: it can be Asus, Lenovo, Samsung, cheap Chinese and other well-known tablet models, which the market is full of in abundance.
Eliminate software malfunctions of an android tablet
In simple terms, software errors occur after the installation of third-party applications (including Chinese and low-quality ones), which cause significant harm to the Android operating system. As a result of messy installations of such applications, the tablet does not turn on.
The second type of software breakdown of the tablet is incorrect flashing, that is, replacing the current, official Android firmware with an incompatible one, which resulted in a failure to boot the Android OS.
Software crash after installing the app or flashing it
Do you like installing applications, games, decorations on Android? If you do this en masse, without reading the description, without removing unnecessary software after testing, expect trouble. Despite the fact that Android, in theory, monitors the activities of third-party applications, sometimes a clumsy application can cause a very unpleasant crash, after which Android simply crashes and freezes (loops) when trying to log in. In this case, of course, the screen backlight works.
How to turn on the tablet... The safest and fastest way to solve the problem is to perform a hard reset - that is, reset the firmware to the factory one.
Fixing hardware malfunctions of the tablet
Hardware (mechanical) failure of the device also leads to a situation where the tablet turns off and does not turn on. For example, if you dropped the tablet, accidentally damaged it, noticed a defect on the case after giving the tablet to a friend or acquaintance - all this can cause a malfunction. Depending on the severity of the hardware damage, the tablet may not work correctly or not turn on at all - in the event that a vital component for the tablet's functioning fails.
So, let's look at the main types of tablet hardware malfunctions and what to do in each case.
The tablet is discharged or the battery is out of order
The tablet does not turn on, although it worked stably for a long time and did not cause any complaints. The device does not respond when the power button is pressed.
How to turn on the tablet... I have compiled a detailed manual,. I recommend to take a look: perhaps in this way you can "with little blood" decide why the tablet does not turn on. Tablets Samsung, Asus, Lenovo, even with a high-quality assembly, are subject to similar problems after several years of operation.
In any case, we advise you to connect the tablet to the charger, wait 10 minutes and then press the power button of the mobile device several times. Also try holding down the Power button and waiting for 10 seconds until an image or other sign of life appears on the tablet screen.
The touchscreen flew on the tablet
An obvious enough problem: the tablet works, but you cannot observe the results of its activity, since the screen simply does not work. In general, this is a very rare type of malfunction, since the touchscreen itself, in practice, cannot fail. To do this, you need to disconnect the contacts on the board or break the tablet screen.
How to fix... What if the tablet does not turn on precisely because of a defective touchscreen? If you are sure that the tablet does not work fully due to the non-working touchscreen, contact the specialists who will help you find the required matrix model and replace it on your would-be tablet. If you have the necessary repair skills and straight hands, it is quite possible to replace the touchscreen on the tablet on your own. It is not difficult to find and order this component on ebay.com. Specify in the search the desired device model (Samsung Galaxy ..., Lenovo ..., Asus ..., etc.), select the delivery method and expect the parcel with a touchscreen.
Serious physical injury
You dropped your tablet on the ground, in water, accidentally put it in the oven, or just let a good friend use it for a while. As a result, the tablet does not work, with obvious signs of damage.
How to fix... What if the tablet does not turn on after a serious hardware failure? Alas, the only proven method remains: contact the service center, describe the problem and pay money.
If your tablet is under warranty, there is little chance of getting it repaired free of charge. However, under the terms of any warranty, you will not be able to repair or replace the tablet if the cause of the breakdown is careless use and / or breakdown due to the fault of the tablet user. In this situation, it remains to contact a paid service center and fix the defect on a paid basis.
Question answer
I ask you to help me figure out the problem with the tablet. I'll tell you the reason. The tablet worked, I watched the movie. Then I felt that he was very hot. Turned off the tablet and turned it on again. I worked a little and suddenly the tablet screen went out, it became dark as if it turned off. The tablet does not turn on.
When the charger is connected, there is a charging signal (the light is on), and the screen is dark. Please tell me what to do if the tablet does not turn on. What is the reason, can it be eliminated or thrown away immediately.
Answer... Buy a new battery - it is possible that it is out of order or has ceased to hold capacity. Since the charger is working correctly, there shouldn't be any other problems.
A rather unpleasant thing happened to the Asus tablet today. I was watching a video on YouTube, suddenly my tablet began to lag. I decided to wait a bit, but it didn’t help and he didn’t stop lagging. I decided to press the screen lock button (I have been using this method for a long time on my phone, and it helped me) then the screen went out, I started pressing the screen lock button again, but the tablet did not want to turn on! It's a pity, the tablet is new, literally a month for him! Why won't Asus tablet turn on and how to turn it on? I'd like to fix this problem!
Answer... One of the main reasons the tablet won't turn on is the battery. The tablet may have had a very old battery installed at the time of purchase. Try charging your Asus via a USB cable or from a charger. We advise you to replace the battery with a new one (fortunately, the Chinese ones cost about $ 10).
I calmly watched the series on the Asus tablet. I started to lay down the tablet, not heated, I just turned it on. I decided to wait, the screen turned off, the sound went on - the sound passed. I decided to wait and then turn it on. But it does not turn on !!! What to do? Granny's tablet is not mine !! I watched the series on a verified site for 6 days already, and nothing like that happened. The asus tablet is 4 years 2.5 years old, did not use it at all, and when they started using it, it was only 2-5 times a month. Why won't my tablet turn on? HELP ME THE PARENTS WILL KILL FOR THAT I BROKEN THE TABLET WITHOUT DOING ANYTHING !!!
Answer... Most likely a battery problem. Put the tablet on charge, after half an hour try to turn it on. If it does not work, make sure the charger is working properly. If all else fails, take the tablet to the nearest repair shop.
Lenovo tablet suddenly froze and did not respond to touch. He also did not respond to the lock button. Then the screen went out. And now the tablet won't turn on.
Answer... If there is no physical damage to the tablet, the problem is with the tablet battery. See above in the text, we have already answered similar questions.
I returned the tablet to factory settings. The removal process went through and the tablet just turned off and does not turn on, but it vibrates every 3 seconds. What could be the reason for this?
I had trouble hanging on the screensaver of the LG tablet. I pulled out the battery many times and tried to turn it on, it did not turn on. I started looking for information on the Internet. Found how to Hard reset. Made it. Lost everything. Tablet contacts, notes, bookmarks, messages, messages (whatsapp, telegram), in the browser I also bookmarked those web pages that I need. In general, everything that I remembered on the device, wrote, etc. everything is lost. Please tell me how to restore all this with accuracy at least up to 100% by what program? If I need to pay I can pay you if only you tell me what and how to do so that everything comes back. Thanks in advance for your reply.
Accidentally the tablet (lenovo tab) fell to the floor. After that, it did not turn on for a long time (it only vibrated and the screen does not light up), and then the screen turned on but was black. When unlocking (swipe up), a sound is heard (I have a click (it should have been)), but the screen does not show anything. I wanted to reboot, but I can't see the shutdown confirmation on the screen (I can't press “shutdown” on the screen). There are no cracks on the screen, no scratches either. No games. The tablet works this way (I can hear it by sound and vibration when pressed), but the screen does not show anything. What can it be and what to do about it?
I turned off the Lenovo tablet, then when I turned it on it said: there was a system error, just wait and turn off the shortcuts, I tried everything again but it does not turn on, the same shortcut please help me.

On the Xiaomi Redmi 4a tablet, the OS is covered. It does not turn on, loading is in progress (until the charge runs out). In service centers they say a frequent case, flashing will help. There are still photos / videos on the internal memory. Is there an option to save these files?
I have such a problem: an old 4s tablet requires an update (it does not turn on, the Aityuns sign and the cord are on the screen), but I understand that after the "recovery" all my photos will be deleted, but I do not quite understand, they will go to the deleted ones, or resetting to factory settings will permanently erase them. And what am they doing to me now: restore / update it or try the programs you recommended in a state like now "locked"? 6500 photos, before that the tablet was updated in 2012, did not fall anywhere, did not sink, .... can I restore all photos or 168?
The tablet worked, turned off at night and during the day it simply does not turn on. I was charging at night. No mechanical damage.
