How to turn on the tablet it does not. Let's figure out how to turn on the tablet without the power button Acer A3-a11

Today, tablet computers have long ceased to be a luxury; they have now become accessible to the mass consumer. As sad as it is to admit this, not a single tablet computer is immune from all sorts of breakdowns and problems.

All problems that arise with tablet computers can be divided into two main categories: hardware failures and software failures. The latter are associated with malfunctions of the tablet’s operating system, and the former are associated with malfunctions and breakdowns of the gadget’s “filling”.

Hardware failures are caused by all kinds of physical damage. If you drop or hit your tablet, hardware failures may not appear immediately. The device may work fine for a while, but then it may not turn on after a reboot.

Your tablet won't turn on?

First of all, remember whether you dropped it or hit it not so long ago. You should also inspect the gadget for external visible damage. If you find scratches or, especially, cracks on the surface of the tablet, you need to take it to service center, since it is better not to do independent repairs.

Repairs should be left to a specialist.

If you do not find any visible damage, possible reason The reason why the tablet computer does not work is due to software glitches in the Android OS. You need to press and hold the power button for about 15 seconds, and then try to turn on the device by pressing the button normally.

In case if this action did not help, you can try to restart the device manually. Each tablet has a reset button, most often it is small in size and securely recessed into the computer case to avoid the possibility of accidental pressing. You can press the button using a sharp object - a toothpick, a thick needle or a paper clip. However, you should press the button very carefully without damaging it.

If a simple reboot does not help your tablet, you can use the “hard reboot” technique. This technique performs a system rollback, returning the operating system to its factory default settings. This reboot will delete all applications that you installed, as well as files that were loaded directly into memory tablet computer. Accordingly, this is an emergency method only for those situations when a regular reboot does not help.

To perform such a “hard reset,” each manufacturer, and sometimes even each model, has its own combinations. Most often, you need to simultaneously press the power button or the reset button, as well as one or more buttons. The button combination is indicated in the instructions for the tablet computer or can be found on the Internet. Before performing such a reboot, it is better to remove the memory card and SIM card from the tablet. After pressing the combination, a menu will appear on the screen of your tablet in which you should select Settings - Format System - Reset Android.

If this method does not help your tablet, you can reflash it - install the operating system again. If you have never done this yourself, it is better to contact a specialized service center, since Android installation differs depending on the tablet model.

If the tablet starts up, but its screen remains dark, most often the cause is a faulty video adapter. In this case, you also need to contact the service center.

It sometimes happens that your tablet breaks down and does not turn on. Let's look at the situation when the device accepts charging, but does not turn on.

Gadgets can break down for a variety of reasons; it is important to react correctly and find out what to do if the tablet accepts charging but does not turn on. If you understand the essence of the problem, you will quickly solve it.

There are many reasons why gadgets stop working, but the main ones are viruses, failure in the firmware, operating system, water ingress, battery damage, or exposure to the cold for a long time. Therefore, before you start to panic, you need to conduct a diagnosis.

How to test the device?

  1. First, find out if the device has received any damage. Maybe a child was playing with it and accidentally dropped it. If this is the case, then you need to go to a repair shop, since you won’t be able to solve the problems yourself. If there was no damage, proceed to the next step.
  2. Problem with the power supply. The most common reason. To make sure this is true, replace the cable or the entire charger. If a person is well aware of the features of electronics, then restoring the operation of the power supply will not be difficult. Often capacitors stop working in it
  3. A loose connector or its deformation may be the reason why the tablet charges but does not turn on. To clarify that this is the reason, move the end of the charger when connecting to the gadget. If the battery indicator lights up frequently, then the problem really lies in the malfunction of the connector
  4. If after all the steps the problem still bothers you or the power button does not work even when you press it for 10 seconds, then you need to reboot the entire system, that is, reset it to factory settings.
    If there is no voltage in your outlet, then this turns charging into a useless process. To avoid this, turn off all devices that consume a lot of power
  5. If your tablet is completely discharged or you just put it on charge and are trying to turn it on, then nothing will work. Give him 10 minutes to get a little energy and he'll be fine.

The problem occurs due to incorrectly installed programs or games. In this case, reset your phone to factory settings.

Sometimes changing the firmware helps. An experienced user can do this quickly and without problems, but an inexperienced person needs to go to a repair shop.

Instructions

The first thing you need to do is understand the reason for the tablet malfunction. They can be divided into two groups: hardware and software. In the first case, these are problems in the operation of some parts of the device, in the second - problems in the operation of the operating system or applications.

It’s trivial, but it still may not turn on if it is completely discharged. Don't be alarmed if you put your device on charge when it's turned off and you can't use it. It will take 10-15 minutes to get started. Periodically try to turn on your device by long pressing the "power" button. If your tablet has been running for a long time and still doesn't work, the problem is probably something else.

When charging the device, it doesn’t hurt to check the operation of the charger. If the charging icon does not appear on the screen for a long time, try connecting another device with a similar connector to it.

If the tablet is charged, but nothing happens when you press the power button, try to remember if the device was dropped, was subjected to a strong shake, or if you hit the screen.

If not, it may only seem like a tablet. To check this, pay attention to the sounds the device makes and the backlighting of the keys. If the tablet makes noise or clicks, you can see mechanical damage, or its buttons are lit, then most likely the problem is with the display. In this case, you are unlikely to be able to do anything yourself; it is better to take the device to a service center.

The image may also be missing if the video adapter breaks down, but even in this case, disassembling and repairing the tablet is not recommended.

If the tablet computer has no physical damage, then it may not turn on due to a software malfunction. In such cases, you should see clear signs that the device is working. For example, it turns on only partially and freezes at a certain point in time (most often, when loading, you see Android constantly lying down).

The reasons for such failures may be an overloaded RAM, incorrect installed applications, incompatibility of some programs, forced termination of some system processes, accidental deletion important files that ensure the operation of the operating system.

If the tablet does not turn on due to software glitches, you can reset the user settings. On every tablet on Android or another operating system hard reset done differently. To find out which keys to use, refer to your device's user manual. Before a full reboot, do not forget to turn off the tablet, remove the memory card and SIM card. Most often, Android devices are reset to factory settings by pressing the power button and changing the volume. They need to be pressed until a slight vibration appears and a menu appears on the screen. In the menu you need to find the Reset Android item. As a rule, it is located in the settings, format sistem section. The disadvantage of this method of restoring the device’s operation is not only resetting all your personal settings, but also complete removal all data. Therefore, it is better to avoid situations where the tablet does not turn on.

In some cases, you can improve the operation of the device by flashing it. However, if you have never encountered this, it is better to address this issue to a specialist.

I play or watch a movie on my tablet, but... it doesn’t turn on. You are perplexed and the only question that interests you is why is this happening?

Do not immediately send the tablet to the service center

Instead of panicking, let's find out why the tablet won't turn on and how to figure this situation out on your own.

The tablet does not turn on - what could be the reasons?

First of all, problems with equipment of this kind can be divided into two types - mechanical - problems with the integrity of the device or with its parts, or with the system or software, that is, its internal contents.

Checking the integrity of the device

It is logical that first you need to check the external integrity of the tablet, for which we will be guided by the following recommendations:

  • Check if the battery is charged and remember the last time you charged the device. If it was a long time ago, and then you did not use the tablet for a long time, then it could be very discharged. Therefore, try turning it on, wait a few hours - at first, in some cases, it does not even show that it is charging.

  • If you see that charging does not occur even after several hours, the problem may be with the charger itself - then you should try connecting another one to the tablet or connecting this accessory to another tablet. This way you can understand who is to blame - your gadget or the charging device.

  • If you are sure that everything is in order with the charge, inspect the entire device for damage, but do not disassemble it - you can only make it worse.
  • If the tablet does not respond to charge, has not been dropped or damaged, but completely refuses to respond to any actions, most likely the issue is a malfunction of one of the parts. In such a situation, all that remains is to take it to specialists to find out what is the reason for its failure.

Please note that in some cases, repairs may cost you more than buying a new tablet. Why? This happens if, for example, the video adapter breaks down. But this is the worst case scenario - you should always hope for the best.

Looking for problems with the system

Why won't my tablet turn on? If you see that it doesn’t load completely, but shows signs of vital activity - for example, the screen lights up but goes out after a few seconds, the loading logo appears, but things don’t go further, or you get the icon of a broken Android, then all is not lost .

First of all, try rebooting the system using the connector with the Reset key - this usually requires a fairly thin object, which you need to press on a small button inside this socket.

If this does not help, try resetting all parameters and settings to the factory version, which is done as follows:

  • Turn off the tablet, remove the memory card and SIM card, if any, from it.
  • Now you need to hold down the key combination to enable hard reset mode - usually press the volume up and power keys at the same time. This combination may differ in some devices; try several options if the suggested option does not help you.
  • When a menu similar to the BIOS on your computer appears in front of you, you need to run the following commands in it:
  • Settings - Format system - Wipe data/factory reset.
  • To navigate between menu items, use only the volume keys; to select a section, use the tablet’s power button.

Such a mechanism for restoring the tablet returns it to its original factory settings, in which case you will lose all files from memory, but you will get a working tablet.

In addition to this method of troubleshooting, the logical method for starting the tablet is to change its firmware.

Why is that?

Often, problems with turning on and further starting the system indicate that software does not fit the device or does not work correctly, so it needs to be reflashed.

This is done quite simply using the following steps:

  • Download the appropriate firmware for the tablet to your computer.
  • Write it to a previously formatted memory card in a folder called SCRIPT.
  • Insert the memory card into the tablet, try to start it, after which the installation process of the new system will begin.

If neither the hard reset menu helped you, the tablet does not reflash or does not respond to any actions with it, then you really should take it into the hands of a specialist, because you still have not found out why it does not work. Do not risk its performance by opening the case, and do not tamper with its parts - this can only make things worse.
