How do I fix the tablet if it does not turn on?

According to the latest statistics, eachthe number of realized tablet computers increases year by year. The reasons for this are very different: the balance between the dimensions and the computing capabilities of the devices; Absolute silence at work, absence of additional components (keyboard and mouse); energy efficiency; high reliability due to the lack of moving parts. However, if the first questions do not arise, then the latter is not so simple.

Now there is a huge amount ofinexpensive tablets from Chinese manufacturers that do not differ too high build quality, which sometimes leads to the occurrence of certain malfunctions. In some cases, you can not do without contacting service centers, and sometimes it's enough just to find information on how to fix the tablet at home, and apply the knowledge gained in practice. Surprisingly, most often it is possible to "lift" the device yourself, saving money and time. The main thing is always to remember that the answer to the question "is it possible to fix the tablet" is always affirmative, but without believing in yourself, one should not even begin.

Diagnostics

Any repair begins with the definitionmalfunction. All of them can be divided into two categories: software, for which for one reason or another there is a "soft" failure, as well as hardware, when any internal electronic component breaks down. Depending on this, the approach to repair differs.

Probability of self-restorationperformance is higher if it is a system error. Although in the first case you can fix the tablet. A broken screen is one of the most common breakages that can be eliminated without assistance. To do this, determine the display designation, which is indicated on it, order a new one and perform a replacement. Note that models that are listed as compatible may not work in this configuration. Therefore, a 100% match by designation is desirable. If the tablet's operation is broken due to the update of system files, obtaining root access rights, attempts to unsuccessful firmware, then, unquestionably, a software problem that is solved by returning the file system to its original state. This kind of malfunction occurs most often. Consider how to fix the tablet, if it does not turn on.

Preparation

In order to restore efficiencytablet computer, lost due to software failure, which caused the inability to download or any other similar problems, you need to download the Flash Tool to your computer. Actually, it should be familiar to anyone who has ever wondered "how to fix the tablet." This application is designed to work with processors from MTK.

Next we will talk about modelstablets on such computing cores, since they are the most common. It is recommended to abandon old versions of the program, as compatibility with new models in the proper volume may not be provided. Pay attention to the version 5.h.h. This software solution allows you to write to the internal memory of the device new system files, i.e., perform a so-called flashing.

System set

You also need to find and download an archive from thefirmware. It is a collection of system files, usually distributed in a single archive. It is important that it is intended specifically for the restored model of the tablet, including its revision.

Best of all, if the firmware will be obtained from the sitedevice developer. For example, for the Oysters tablet, you should not look for a suitable product on the network resources from Apple, Lenovo, etc. You also should not ignore the possibility of finding the right software solution in specialized forums, if the official site for some reason does not support the model. And finally, you need a cable that allows you to connect the tablet to a computer.

Modification definition

It often happens that two outwardly completelyidentical devices are actually different. For example, a manufacturer, collecting a new batch, may begin to install another type of display matrix into the tablet, similar in characteristics but controlled by other drivers. Accordingly, two revisions of the same device, distinguished by the driver embedded in the firmware, will appear on the market. Thus, the one who wants to figure out how to fix the tablet, simply must correctly determine the modification of the gadget.

If the system is not lostfully, this can be seen in the section “About phone - Build number”. For example, in one case the version of SA0001 is indicated there, and in the other SB0001. In this situation, the firmware from one device to another will not work. The modification is also indicated on the board, which is very useful if the device does not start at all.

The boot process of the new system

Archive with firmware must be preunpack to a folder containing only Latin characters or numbers in the title. Then run the flash tool. In this program, select the scatter file, and MTKxxx.bin, to specify the paths to which the dialog is displayed. Flashing mode must be set to Download. After that, you need to press the green start button of the process and connect the tablet to the computer. If everything is done correctly, the system will start booting to the internal media.

Food

The above case with downloading newcontrol programs is, so to speak, the ideal option. Although service centers, even for such work, require impressive remuneration, there is nothing difficult about this, if, of course, a suitable firmware is selected, and a software failure. But how to fix the tablet, if it does not turn on because of the fully "dead" battery? In this case, any attempts to turn on the device are useless, and connecting the charger does not lead to anything. In fact, this is not a breakdown, but a feature of work, which also applies to smartphones, recorders, etc. The reason is in the features of the charge controller, which controls the filling of the battery with energy.

How to fix a tablet that turned off and nottakes charge? An ordinary plastic card with sharpened edges needs to disassemble the body of the gadget and get to the battery. Usually it is connected to the main board with two wires through the controller. Most often it is black ("minus") and red ("plus") cores. You need to take any unit for charging, giving the desired voltage (current - preferably not less than 1 A), and determine the polarity of the wires - often it is indicated directly on the housing. Then unsolder both wires of the battery from the main board of the tablet and wind them up / solder them to the conductors from the prepared charging, observing compliance. The unit should be heated (up to 50 degrees) depending on the parameters. Upon completion, the controller will abort the process, and the temperature will drop. Wires can be soldered back and assemble the tablet. If the problem was in excessive discharge, the device will turn on and will be fully operational.

How to fix a broken tablet

Perhaps this is one of the most difficult breakdowns. If repair is advisable (the device is not broken to pieces), then you need to carefully inspect the damaged element and find a symbol on it that represents a set of letters and numbers. Then, having this data on hand, order a replacement. In this case, each character is important. In fact, how to fix the tablet, there is nothing complicated. One of the conditions for the successful implementation of this operation is the correct selection of programs (in the case of a software malfunction), as well as the exact identification of component models by reference numbers — if there is a hardware failure.
