Tablet computers have confidently entered our life and accompany us both on vacation and at work. The situation is very unpleasant when the device at the most crucial moment does not turn on or does not load beyond the Android logo. The most elementary thing is that it is simply discharged, especially if you actively used the device during the day or night. Then all you need to revive it is to attach the tablet to the charger and wait a few minutes before starting it.
But there are more global problems and they can be divided into three groups:
- mechanical
- electronic
- software.
Such a nuisance can happen not only with cheap brands on Android (Digma, Chuwi, Teclast, Cube, FNF, PiPO, Onda, Colorfly, Ainol, Ramos, Vido, No-name), but also with market leaders - Apple, Asus, Acer , Sony, Lenovo, Huawei.
Let's take a closer look at all three factors in order to determine exactly why the tablet does not turn on. The instructions are universal and suitable for both Android, Windows and iPad, but each case has its own peculiarities.
Power button stuck or broken
If the tablet computer is dropped, the power key could be damaged in the first place. Inspect, it should not sink or wobble; when pressed, there should be a characteristic click sound. If there is a violation in the action of the key, then you will have to disassemble the tablet and inspect the nature of the damage. Most likely, you will need to solder the key or replace it with a new one if the contacts are broken. Repairing the mechanical button will not be a problem; you will have to tinker with the membrane.
The charging connector is broken
If the ON / OFF key is working properly, then you should inspect the charger connector. If you sin by pulling the wire out of the socket very abruptly, exposing the mobile computer to moisture, or dropping it often, sooner or later this will lead to a breakdown of the connector. The deformation of the socket leads to the fact that the plug will not enter the connector, will not enter completely, and even may overlap with some part of the case or break off if the blow was quite strong. Damage to the pin connector will prevent the device from charging. And in this case, you will have to disassemble the case and solder the contacts or completely change the charge socket.
Broken wire
It is possible that the device does not start simply because you have a faulty charger. Check the housing for swelling, distortion, cable breakage. If there is damage in the wire, then it is quite possible to replace it yourself. Fractures of the cord are not visible, so it will be correct to check it for operability by connecting it to a phone, e-book, etc. and check the charge supply.
The removable battery can be powered directly. This method is unsafe for the battery, but if you are willing to take the risk, then it is possible. The battery from this process becomes unusable very quickly, so do not abuse this method of recharging.
There is a safer way to recharge the battery - using a universal charger, called a "frog"
Use these methods only if you are completely confident in your abilities. It is better to entrust the repair to professionals, rather than risk it.
Electronic problems
Charger burned out
If the charger was exposed to moisture or was connected to the network without a voltage stabilizer, then it could well have burned out. The only way out is to buy something new and, preferably, original, which is not always possible.
Brands such as Asus fonepad 7 me372cg, Huawei MediaPad M2, Samsung SM-T311 Galaxy Tab 3 8.0, Sony Xperia Z2 Tablet, LENOVO Tab a5500 n have the opportunity to buy an original charger, then to the Chinese brands smarto 3gdi10, 4good light at300, digma plane 7546s 3g, explay xl2 3g, ainol novo 9 spark, bq, thomson hero10sco, irbis tz185, you will have to select the charger based on the characteristics of the burnt block. Pay attention to the voltage (standard - 5 volts) and how many amperes (recommended from 1A to 2.5A) the purchased adapter gives
In the meantime, try charging from USB by connecting it to a computer or external battery.
This topic is discussed in more detail in this one.
Battery died
Modern gadgets are equipped with lithium ion or lithium polymer batteries. These batteries are equipped with charge controllers, which are responsible for preventing deep discharge of the battery. It is impossible to store such batteries - batteries tend to lose capacity. It is necessary to ensure that they do not discharge to zero and do not overheat above 45 degrees.
The average battery life with active use is 3-4 years (about 300-400 cycles).
To check the battery, you need to measure the voltage on the battery and the board. Take out the battery and plug in the charger. Now check the readings on the voltmeter, the parameters should correspond to the following data:
| CHARGER | BATTERY | PAY |
| 5 V | 3.7 V | 3.9 - 4.2 V |
| 9 V | 7.4 V | 7.9 - 8.2 V |
| 12 V | 7.4 V | 7.9 - 12.2 V |
Water got on the microcircuits
Contact with water is very harmful. Anything can happen here - oxidation of contacts, malfunction of speakers, fire, overheating. Getting on the microcircuits, the liquid leads to a short circuit and turns smart equipment into a brick. If it suddenly happened that water got in, then the first thing to do is turn it off. Then turn the tablet over with the display upward to prevent the penetration of liquid to the internal elements. If possible, remove the battery, SIM card and USB flash drive. Remove moisture thoroughly. You can place the tablet in the same position in absorbent absorbents - the simplest and most commonly available is rice. After that, let the device dry completely for at least a day.

If, after all the manipulations, the tablet does not turn on, it is better to trust the hands of professionals in the service center.
Malfunction in the screen or video adapter
It happens that the tablet PC functions and the display simply does not light up. Feel the back cover - it should be warming up. The tablet makes little noise or vibration when turned on. There are two options - either after the firmware, the action of viruses or other program action, the display does not start, the touchscreen is damaged, or the video adapter has died. In the first case, a factory reset or flashing is required. It will be necessary to replace the train if the latter came off after the impact.
To check the video adapter you need a TV or computer. New generation gadgets have a mini or micro HDMI video output, with which you can connect a tablet to a TV. If the problem is in the display, the image will appear, but if the video adapter is damaged, the TV screen will remain dark. It is better to entrust such repairs to specialists.
Burnt out processor or memory
With a strong daily load and running a large number of applications, the processor may overheat or even burn out, which will cause a malfunction of the mobile computer. Very few modern devices use a built-in cooling system. Moreover, you shouldn't count on it if you have a cheap mobile PC. The more you use your tablet, the more often your CPU overheats, which leads to a loss in performance. When the maximum permissible temperatures are exceeded, microcircuits, loops, RAM, printed circuit board suffer, which will lead to a short circuit of the power circuits. Repair of the processor is carried out only in a service center, but it will cost a pretty penny.
If the tablet won't turn on, it's worth checking the flash memory. If you have experience, then you can try to make the repair yourself, while even increasing it.
None of the above helps - perhaps the problem is in the software.
Software crash
Sleep mode activated
Sleep mode is one of the common reasons why the gadget does not start. If at the moment the operating system enters the sleep state, the device freezes and cannot start downloading Android in the future. To remove the sleep mode, connect the tablet to the charger and turn it on after a few minutes. To avoid such difficulties in the future, turn off the sleep mode in the settings.
Viruses
It is rare that the device does not function due to a virus attack. More often it loads at least before the splash screen and freezes. In this situation, it is necessary to carry out a complete cleaning with a good antivirus program. To do this, connect the tablet to a personal computer or laptop using a USB cable. After that, reset the settings to the factory settings (the so-called Hard Reset, details).
Lack of memory
Sometimes the tablet won't turn on due to lack of memory. Remove the card and try to turn on the device without it. Clean the OS from recently installed applications, uninstall unnecessary ones. Programs that are incompatible or incorrectly installed overload the RAM. Also, avoid forcibly shutting down the system so as not to delete the files responsible for its operation.
After removing third-party software
If the gadget stopped functioning after uninstalling the application, then returning to the factory settings will help here:
- take out the flash card and sim card
- press the volume and power buttons at the same time
- navigate through the BIOS items using the volume buttons, the selection is the Power key
- select the item - Wipe data / factory reset
Be prepared for the loss of personal data.
Before installing any software, you must make sure it is compatible with the machine. For example, such a program as Paint Tool SAI, which works great on powerful devices. But after launching which a simple tablet (dns, dexp, supra, digma, equator, tech, explo, thomson, nexus, prestige, etc.) freezes and stops responding to any actions, since it is not intended to install this software according to its characteristics ... After uninstalling this application, graphics drivers crash and disrupt the PC. Only graphic tablets such as Wacom Intuos are suitable for such a program. Do not load something that is not intended for the device and then you will not have to ask the eternal - “because of what”.
After flashing
The flashing process requires a certain skill, so unsuccessful intervention often leads to the loss of the mobile PC's performance. Most likely, the firmware version is incompatible with the Android OS installed on the gadget. In addition, if the cord is disconnected in the process, this is a guarantee of "oskirpichivaniya". We recommend that you roll back the software to its original state or use low-level utilities to restore functionality.
If during the firmware process a disconnection occurs and the data transfer is interrupted, you must do the installation again.
It may also be the fault of the developer of the updates - they turned out to be incompatible with this version of Android. Return everything to its original form and disable the update in the settings. At least until you are sure of the reliability and functionality of these updates. Download updates suitable for your particular model - Huawei t1 701u, acer w700, Samsung GT-P5100 galaxy tab 2, Samsung Galaxy Note 10.1 GT-N8000, samsung galaxy tab a 10 5 sm t 595, samsung sm t311. It's harder to find updates and firmware for little-known and cheap brands - 4good light at200, Irbis tz720, LG G Pad 8.0, oysters t12 3g, oysters t72hm 3g, prestigio MultiPad PMP5580C, Ritmix RMD-1050, Roverpad Air Q10 tz178, Irbis 7b, 3q tablet pc qoo rc0721b, Chuwi, dexp, Turbokids, Smarto, etc.
If, when loading the OS, there is a drop or freeze on the Android logo, then not everything is lost and you can repair it yourself. You can restore a tablet PC from a brick state using the Recovery program by installing it on a PC and connecting the tablet. But each specific model must be dealt with separately, there is no general instruction.
This happens after incorrect flashing, or installing software with access to Root rights. First of all, try resetting to factory settings through the bootloaders menu (Recover mode - hold down the ON + Volume UP button). If this option did not help, then reflash the device with an official, stable version of the software.
Flashes or stripes on the screen
A negligent attitude towards the tablet leads to disruption of the display and other components. The slightest bump or fall may cause the screen to malfunction. The most common thing is to disconnect the shield module loop. To restore, it is necessary to open the device and install it in the appropriate slot.
After the fall, the matrix and touchscreen will be damaged. The display will start to ripple, strip, show "partially", does not turn off. The hand of a master is needed here. And be prepared for costly repairs.
A software glitch is the rarest cause of display flickering. Factory reset will help here. In the most extreme case - flashing with a stable version of the software.
Also, stripes and flickering may appear from overheating of the gadget or water ingress.
Doesn't load beyond the logo
If the screen is on (works, but black), and the device hangs and does not load, it is measured after entering the password. Use the reset button - Reset. It is she who will help if the operating system stops loading. If you did not find the reset on your tablet PC, then try clearing the cache:
- Hold down the power and volume keys at the same time
- In the menu, select the wipe cache item
- We select the inscription reboot system now
If this does not help, then we reset the settings in the same menu.
And finally - if the new device goes out and does not respond to the power button, then it is possible that the battery was completely discharged from the long non-use of the device. Connect the tablet to the charger and wait. It is necessary to carry out several charging / discharging cycles for the battery to return to normal. If it does not help, change it under warranty.
If the tablet starts up, but does not function properly, clean it with an antivirus through safe mode, uninstall third-party applications. Clear your cache. So it will be possible to save personal data, but get rid of the slag in the system.
We have analyzed the reasons and now it is clear that most problems with the tablet PC can be solved by resetting the settings through the entrance to the hard recovery.
conclusions
Respect for your favorite device is the key to long-term functioning. Timely replenishment of energy, careful loading of third-party software - this will only contribute to a long and fruitful use of the gadget. Do not forget to clear the RAM, do not overload the device and then you will not have to look for answers to the question "where to run and what to do" if the tablet stops turning on. You can fix it yourself, but if you are not confident in your abilities, it is better to trust the specialists.
Quite often people complain that their tablet does not boot. How to be in this situation? What actions will help "revive" the device without much difficulty? Is it possible to somehow turn on a gadget that refuses to work? Why does the tablet sometimes fail to boot at all? Sorting out all this is not as difficult as it seems. And this is despite the fact that there can be many reasons for this phenomenon. It is enough to carefully remember what preceded the breakdown. So what if the tablet doesn't work and doesn't want to boot?
Classification of causes
It has already been said that many situations can be the source of the problem. There is a certain classification of them. She half helps to understand what happened, and to draw up a further plan of action.
Tablets and other devices may refuse to work and boot normally under the following conditions:
- due to hardware problems;
- in case of failures in the installed software.
As a rule, in the first case, it is impossible to say for sure whether it will be possible to bring the gadget back to life. But in the case of software, most often it is possible to restore the tablet's performance without much difficulty.
No charge
Now a little about what specific problems users have and how to solve them. Tablet won't boot? "Android" or whatever is not so important. The first step is to make sure the device has enough power to get started. As a rule, if it is not there, then the gadget will refuse to work.
Sometimes the tablet boots up and turns off immediately. In some situations, the screen turns off after the manufacturer's logo. Such situations indicate that the device has a little energy, but it is not enough for normal operation of the system.
In such situations, it is suggested:
- Connect the tablet to the network, wait a little and try to turn it on again. As soon as the charge appears, the problem will disappear.
- Replace the device battery. Sometimes it is a bad or faulty battery that causes the tablet to not boot.
Manufacturer
The next common reason is the manufacturer. Tablet won't boot? You shouldn't be surprised at this phenomenon when it comes to Chinese products. In particular, duplicates from well-known manufacturers.
If a citizen has a Chinese tablet, then the problems associated with turning on the device can be eliminated by the following methods:
- rebooting the gadget (constantly trying to turn it on);
- repair in a service center;
- buying a new device.
In practice, most often, Chinese devices are reanimated by handing them over for repair, or the problem is solved by purchasing a new tablet. The original gadgets rarely have problems and malfunctions. But no one can be 100% insured from them.
Viruses
Does the tablet turn on but won't boot? In fact, this phenomenon is not so rare. In practice, many users have encountered similar situations.
Problems with turning on tablets are sometimes caused by viruses that have entered the operating system of the gadget. Now there are a lot of various infections that bring them down to the OS of phones and other mobile devices. His treatment will help bring the gadget back to life.
It is usually carried out in service centers. It is not recommended for users to check and clean the tablets on their own. Otherwise, you may face a complete crash of the OS.
Settings
What if the tablet won't boot? Don't panic is the main thing. Most situations can be resolved without much difficulty. It is enough to know how to act in this or that case.
For example, sometimes the reason that the tablet does not boot is the broken settings of the operating system. You can "reset" them. After this step, the device starts working normally.
Hard reset
Resetting the settings for mobile devices is called "Hard Reset". It is carried out according to a specific algorithm. The help of specialists is not needed here - everyone is able to cope with the task independently.
Tablet won't boot? Before sorting out the possible causes of the problem, it is recommended to carry out a "Hard Reset". It is proposed to activate this function according to the following algorithm:
- Remove the SIM card and memory from the device. These are not required steps, but it is best to take them to work properly with the operating system.
- Simultaneously press the power button of the device, as well as the volume controls.
- Keep the buttons pressed for a few seconds. The device should vibrate and turn on.
- On the screen, select "Settings" - "Format".
- You need to select "Restart", or Reset. The device will perform the mentioned action. The settings will be reset during the process.
It is this algorithm of actions that will help to reset the settings to the warehouse. If this was the problem, then after the procedure the tablet will work with renewed vigor.
Firmware
However, these are not all the reasons why the device under study refuses to work. As mentioned, sometimes the problem is in the software. Does the tablet not load beyond the logo or refuses to work normally? Then it is proposed to use another technique. But it is better to use it after activating the "Hard Reset" option. What is it about?
About the firmware of the operating system. Problems with this component lead to the fact that the tablet does not load. It is recommended to restore the firmware to its original state. How to do it?
For self-resetting, you can use the following procedure:
- Press the power button on the device at the same time, as well as the volume control button.
- Wait for the tablet to vibrate. As soon as it appears, release the pressed buttons.
- In the menu, select "Settings" - "Firmware recovery".
- Wait until the end of the process.
It should be noted that if it is impossible to enter the recovery mode, the source of the problem with turning on is precisely the hardware damage. Most likely, you will have to carry the gadget to repair or just buy a new device.
Flashing
Tablet won't boot? Another way to bring the device back to life is by flashing the gadget. It is highly discouraged to carry out this process on your own. In inept hands, flashing leads to the final "death" of the device.
That is why it would be best to take the gadget to a service center. There, for a certain fee, the device will be flashed. After that, the tablet will work like new. But an incorrectly performed flashing can cause a lot of problems for users.
Damage
Does the tablet turn on but won't boot? Or does it not react at all to actions? It is likely that mechanical damage has occurred. It is very common among modern users. There are several methods to correct this phenomenon.
More specifically, the following tricks are worth trying:
- try to turn on the tablet several times;
- take the gadget to the service center for diagnostics;
- change device.
As a rule, mechanical damage can occur with any negative impact on the tablet. For example, if the device falls out of hand. Or he was crushed by some objects. Quite often, girls and adolescents face a similar problem, simply carrying a tablet in bags with a lot of things.
Unfortunately, such situations are most often resolved by direct replacement of devices. There is no point in reflashing or resetting settings. It is best to entrust all manipulations to professionals.
Repair
What if the tablet does not boot, and all the actions that could be taken have already been completed? In this case, there is only one thing left - contacting the service center. For a fee, specially trained people will carry out a complete diagnosis of the device, and will also help bring the tablet back to life. Of course, if this is possible.
Most often, this method is the least problematic. The service center will be able to change the firmware and some damaged components of the tablet. Only in some cases even contacting such an organization turns out to be useless. This means that you will no longer be able to turn on the tablet - you will have to buy a new one.
In fact, you should not be afraid of a situation in which the tablet or phone does not turn on. If you do not want to understand the problem for a long time, it is better to take the device for repair right away. This is the safest and best solution.
You are reading this article because you cannot start your tablet. There can be many causes of malfunctions, they can be both hardware and software. But that's not what this article is about. Why the tablet does not turn on and how to reanimate it, we will consider in this article in more detail.
Method 1: check your unloading device
In order to check the charger, it is easier to use a multimeter. The tablet should output 5, 9, or 12 volts. If there is no multimeter, then ask someone for a charger with the same connector as on your tablet, but be careful that the voltage of the charges is the same. Enough the charger often fails. Most of the time this happens with Chinese models of tablets. If the charging cord has a USB connector - You can also try charge it through your computer. It should be borne in mind that the cable itself may be damaged. It is better to ring the cable first or replace it with a known good one.
You can do it a couple of times, just try it while connected. m charger. If the tablet does not turn on in these cases, then you need to find a small hole on the tablet with the RESET inscription. Using a toothpick or other similar object press the button.
Method 3. HARD RESET
If nothing happens after the reboot, then the Bootloader is damaged. Bootloader- it is the bootloader that controls the operating system kernel to boot the tablet normally. Then Hard Reset should help. follow-up remove the SIM card and memory card from the tablet. To do this, you need to hold down the power buttons and the volume rocker down or up (depending on the model of your device). Will start menu, in which you need to select the item Settings, then Format system.
Method 4: Broken Power Button
The tablet may not turn on due to a broken power button. As a rule, the button has a characteristic click and should return to its place after being pressed. If this does not happen, you need to check it with a multimeter. Most likely there are 4 contacts, you can try p rip button.
Method 5: check b batteries
You need to disassemble the tablet, disconnect the cable or battery power connector and connect the power supply to it. Next you need use a multimeter and check the voltage at the output of the battery.
If you have a 3.7 Volt battery (5 Volt charging), then the voltage should be between 3.9-4.2 Volts;
If you have a 7.4 Volt battery (9 Volt charging), then the voltage should be between 7.9-8.2 Volts;
If you have a boosted 7.4 Volt battery (12 Volt charging), then the voltage should be between 7.9-12.2 Volts.
If the voltage is lower then the battery is out of order.
Method 6: checking the display
It happens that the tablet turns on, but the screen is black. And it seems that the tablet does not turn on. You need to be sure that it is charging, then turn it on and wait 15 minutes. The tablet should warm up slightly in one of the side parts. If so, there is a problem with the display itself. You need to disassemble the device and look at the contacts that connect the display to payment. Maybe the latch came off , this is most often due to falls.
Method 7. Repair at a service center
professional equipment for repair;
work experience of masters 5 years;
1 month warranty for the work performed;
availability of branded original spare parts.
If you want to save time and not put your device at risk, tablet repair in Odessa carry out outsourcing to the IT service center.
No matter what operating system your tablet runs on, no matter what money you pay for it and no matter how carefully you treat it, gadgets can break from time to time. It's one thing if the device is out of order due to your fault, that is, dropped, drowned or rubbed something in the OS through carelessness, and quite another thing when one of the elements breaks for no seemingly obvious reason.
One of these reasons is the gadget's power button. It's good if the tablet was turned on at that time, and the breakdown can be somehow fixed by the built-in software, but it's another matter when the device is turned off, and reviving it without this button is a big problem.
Causes of breakdowns
Let's try to figure out how to turn on the tablet without the power button: recommendations, instructions and factors that can lead to this malfunction.
First, let's look at the main reasons why the gadget stopped turning on. There are quite a few of them, but they can be conditionally divided into two groups: mechanical and software. That is, physical damage to the device or a failure in the operating system, respectively.
Mechanical damage
Before turning on the tablet without the power button, carefully inspect the case of the device. The gadget may stop working if you drop it, for example. Most of the components of modern mobile devices are made of fragile materials and components, and you do not need to apply special efforts to damage them.
With rare exceptions, the tablet may fall on the power button. A strong blow will easily cause damage to boards, cracks on microcircuits or rupture of connections. Is it possible to turn on the tablet without the power button in this case? Most likely no. The only option is to contact a nearby service center for the repair of mobile equipment, unless, of course, you have not graduated from a technical university. But even the last argument does not always help, because for the repair you will need a special tool - you definitely cannot do with a regular screwdriver and pliers.
Software glitch
Before turning on the tablet without the power button, it will not be superfluous to make sure that the operating system is adequate. It often happens that after installing third-party software from suspicious resources, the platform behaves somewhat strange and buggy. An OS failure can also occur from an incorrectly delivered update.
At its core, a tablet is the same computer, only smaller and on its own platform. Therefore, catching a virus or "catching" an operating system crash can be done without any problems. In this case, the question of how you can turn on the tablet without the power button is not as acute as with mechanical damage, and you can solve the problem on your own, that is, without going to the service center.
Trying to turn on the device
The function key of inclusion should not somehow bend, sink or "walk" in the groove. If the mechanism is broken, then you will not hear a characteristic slight click - pay attention to this before turning on the tablet without the power button. If the key is responsive and no mechanical damage is observed, then, most likely, the matter is in the "brains" of the gadget. Solving this problem takes a lot of patience.
First of all, open the instruction manual for your device and look for a section with "hot" and "cold" start (Recovery section) for your device. As a rule, this is the standard combination - volume up with the power off key pressed. They are not very flattering about this method, because in this case all the insides of the gadget are subjected to a strong "shake-up". If it was not possible to enter the "Recovery" mode, then most likely you will have to contact the service center.
Recovery Mode
Nevertheless, it is worth trying to revive the device with some other moves. Before turning on the tablet without the power button, be sure to make sure that the cables and connectors that you will be using are "native", otherwise the likelihood of a successful repair will significantly decrease.
- If the battery is good, you can connect the tablet to the charger. It is unlikely, but sometimes the device shows signs of life and starts up in "Recovery".
- Also, it will not be superfluous to try to connect the gadget to a personal computer or laptop via a USB interface. The device can understand this action as synchronization and enable the appropriate protocols.
- If, by pure chance, the "Debugging via USB" mode was enabled in your settings, then using the ADB developer software environment, you can launch the gadget through the computer interface (command line cmd.exe). It is enough to type in the “adb reboot recovery” field, and then use the volume key on the device to select “Reboot Device” (reboot the device).
Judging by user reviews, these steps were able to help most of the owners. If none of the methods helped, then your way to the service center, and there they will already see what happened to you and how to deal with it: flashing the device, replacing some boards, connections or repairing the power button.
The tablet does not wake up from sleep mode
In this situation, things are a little simpler than in the previous case. Some particularly competent manufacturers complete their firmware with additional functionality for unlocking the screen using touch gestures.
The operating instructions for the device must contain the relevant information. As a rule, this is a quick tapping on the central part of the screen or frequent, as it were, scrolling.
We remove the device from "sleep"
If the necessary information is not in the manual, then before turning on "Android" without the power button, try the following steps.
- Connect your gadget to a charger. In most cases, the device wakes up from sleep mode.
- Connect the USB cable to a personal computer or laptop. Synchronization protocols should be enabled. Give up the connection to the computer and continue using the tablet by disconnecting the USB cable.
- You can try performing a "rough reboot". Most gadgets are equipped with a small hole with a small button, which is located in the area of the headset interfaces and the volume rocker. Press on it with something sharp and the device should reboot.
- Also, some allow you to reboot yourself with a certain key combination ("Cold start"). The combination is practically unchanged - the power button and the volume rocker up or down. Then we wait 10-15 seconds, and the device should start.
- In the event that the device does not turn on due to an incorrectly delivered update or your intervention in the firmware, then the only correct solution would be to rewrite the gadget. With a minimum stock of skills, this procedure can be performed independently, it is enough to study a detailed manual on a specialized forum.
These recommendations are suitable for devices running Android and Windows OS. "Apple" gadgets have a slightly different philosophy and specifics, but the principle of operation is similar to the first. For example, to perform a Cold Start on iOS, you need to hold down not the volume rocker with the power button, as in Android, but the Home key.
What if the tablet won't turn on
It so happens that in the process of passing games or working on the tablet, it stops working and does not turn on. The main reasons can be conditionally divided into two categories: problems with the hardware of the device are malfunctions of the battery, connecting cables, boards, or some problems with the software - incompatibility of programs, the operating system has crashed or was incorrectly installed after the update process.
Let's take a closer look at individual cases of tablet malfunctions.
There are absolutely no signs of life
1. The simplest and most commonplace reason is a completely discharged tablet battery. To check this version, plug it in and wait at least 10-15 minutes. Only then will the tablet be able to accumulate the minimum amount of energy to turn on. Hold the power button on the device body, wait for the screen to light up. If the screen turns on, check that the charger is working properly - take another one and do the above. The tablet turned on, but the charging process is not progressing, you need to find out if why the tablet is not charging .
2. If a child has played with the tablet, it may have damaged it by hitting the floor or corner of furniture. Most likely, part of the display has suffered, in which case it can be replaced. The tablet itself is in working order. Screen damage is usually visible to the naked eye.
3. If the device did not have any mechanical damage, it is a rare case - the video adapter is out of order.
If you find such signs and there is a valid warranty for the device, run to the salon and wait for the repair, it is simply unreasonable to do the repair yourself.
The patient is neither alive nor dead
When the tablet turns on, but not completely, but freezes during the boot process (there is only a splash screen on the screen), we are dealing with a software failure.
The reasons may be as follows:
1. Some programs or games are not installed correctly.
