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

According to the latest statistics, every year the number of realized Tablet PCs increases. 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 on the market there are a lot of inexpensive 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 determination of the malfunction. 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. The probability of self-recovery 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 replace it. Note that models that are listed as compatible may not work in this configuration. Therefore, 100% match by designation is desirable. If the work of the tablet is broken due to the update of system files, obtaining root access rights, attempts to unsuccessful firmware, then, uniquely, 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 the functionality of the tablet computer, lost due to a software failure that 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 a tablet. This application is designed to work with processors from MTK. Next, we will talk specifically about tablet models on such computing cores, since they are the most common. From old versions of the program it is recommended to refuse, as compatibility with new models in due volume can 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

Also you need to find and download an archive with firmware on your computer. 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.

It is best if the firmware is obtained from the device developer's site. For example, for the Oysters tablet, you should not look for a suitable product on the network resources from Apple, Lenovo, etc. Also, do not ignore the possibility of finding the right software solution in specialized forums if the official website for some reason does not support the model. And, finally, you need a cable that allows you to connect the tablet to your computer.

Definition of modification

It often happens that two outwardly completely identical devices actually differ. For example, the manufacturer, when assembling a new batch, can begin to install in the tablet another type of display matrix, similar in characteristics, but managed by other drivers. Accordingly, on the market will appear two revisions of the same device, differing in the driver embedded in the firmware. Thus, someone who wants to figure out how to fix the tablet, simply must correctly determine the modification of the gadget.

If the system's performance is not completely lost, you can see it in the section "About the phone - Assembly number". For example, in one case there is the version SA0001, and in the other SB0001. In this situation, the firmware from one device to another will not work. Modification is also indicated on the board, which is very useful if the device does not start at all.

The process of loading a new system

The archive with the firmware must first be unpacked in a folder containing only Latin characters or numbers in the name. Then run the Flash Tool. In this program, select the scatter file, and MTKxxx.bin, to specify the paths to which the dialog is necessarily displayed. The flash mode must be set to Download. After that, you need to press the green start button and attach the tablet to the computer. If everything is done correctly, the system will boot to the internal media.

Food

The case discussed above with the download of new control programs is, so to speak, an ideal option. Although the service centers even for this work require an impressive remuneration, nothing is complicated in this, unless, of course, a suitable firmware is chosen, and a software breakdown. But how to fix the tablet, if it does not turn on because of a completely "sat down" 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 the work, which also concerns smartphones, recorders, etc. The reason lies in the peculiarities of the charge controller controlling the filling of the battery with energy.

How to fix a tablet that turned off and does not charge? The usual plastic card with sharpened edges you need to disassemble the body of the gadget and get to the battery. It is usually connected to the main board by two wires through a block controller. Most often this is black ("minus") and red ("plus") veins. It is necessary to take any unit for charging, giving out the desired voltage (current - preferably not less than 1 A), and to determine the polarity of the wires - it is often indicated directly on the body. Then remove both battery wires from the main board of the tablet and fasten / solder them to the cores of the prepared charge, observing the correspondence. The unit must be heated up to 50 degrees, depending on the parameters. Upon completion, the controller will interrupt the process and the temperature will drop. The wires can be soldered back and collect the plate. If the problem was in excessive discharge, the device will turn on and it will be fully operational.

How to fix a broken tablet

Perhaps this is one of the most difficult breakages. If the repair is advisable (the device is not smashed to pieces), then you need to carefully inspect the damaged element and find on it a designation that is a set of letters and numbers. Then, having these data on hand, order a replacement. Each character is important. In fact, how to fix the tablet, there is nothing complicated. One of the conditions for the successful completion of this operation is the proper selection of programs (in the case of a "soft" malfunction), as well as the exact identification of the component models by the identification number - if the hardware failure.
