Why does not the phone turn on? Instruction manual of the phone

As a rule, Murphy's law works at the most inopportune moments of our life. In addition, the modern means of communication, namely mobile phones, are unlikely to be completely reliable. No, of course, no one denies the existence of extra-reliable devices. However, the average cellular device is a rather unpredictable device, and the popularity of the question "Why the phone does not turn on?" Is an excellent example. Let's take a more thorough look at the causal sources, to put it mildly, of an unfavorable situation: the failure of the mobile phone to start when the user activates the "right" button "On".

Calm, just calm ...

First of all, do not panic. Perhaps you are pressing the wrong button! It is likely that the instructions for operating the phone by you were simply ignored, that is, not read. As a result, the banal ignorance of the purpose of this or that key of the device with further use of the device can cause an incredible number of questions. It should be noted that the same button can perform different functional tasks. Often, the on / off button in the operating mode of the machine activates the "block" command. The screen turns off and the phone enters standby mode. At such times an inexperienced user may think that the mobile phone has turned off, and ignorance of how to remove it from the lock is fraught with the loss of not only time, but also nerves. In the new modifications of mobile devices, almost intellectually controlled blocking scheme is used. Therefore, the operating manual for the phone is an important document that requires careful study.

The main reasons for the "non-inclusion" of a mobile phone

So, the manufacturer of the cellular device provides you with the necessary information in the form of a certain instruction. Many underestimate the importance of the attached document. That, in general, is not entirely correct and even inexcusable, given the considerable cost of some modifications of mobile devices. Practice shows that the instruction is simply ignored, at best the user only skims the text of practical recommendations. As a result, the ranks of the "thirsty" answer to the question "Why the phone does not turn on?" Inexorably replenish, and the popularity of the problem is gaining actual weight.

Tip # 1

You will not believe it, but having spent a few minutes studying the instructions for the phone, you will significantly expand the base of your knowledge, moreover, many difficulties will be solved right away. The main thing is that you will protect your device from unjustified operational mistakes, which are made by those who do not deign to use the mentioned free material.

Reason # 1: Energy

Most often you can observe this kind of malfunction: after a short use, given the fact that at the time the device was started, the charge indicator showed the full volume of the battery, the phone was turned off. That is, the battery capacity quickly loses the accumulated energy potential. As a result, we have an extinct phone - "Samsung" does not turn on. Such a precedent can really lead a user into bewilderment ... As a consequence, a person changes the battery. However, not always this "treatment" corrects the situation. As a rule, signs of unusability of the battery are:

• Spontaneous heating of the battery.
• Blowing of the capacitive battery chamber.
• The speed of the charge to the full volume.

In such cases, it is really necessary to replace the energy element of the mobile communication device.

Reason # 2: Charger

The original charger produces "refueling" in the most gentle manner. That is, the charge occurs without jumps and voltage drops. The "filling" mode of the battery capacities is stable, the current and voltage are supplied at the values specified by the manufacturer. In the event that the charger is not quite correctly delivering electrical energy to the hardware of the mobile phone, there is a great risk that the power controller of the device will simply fail. By the way, in this case, a visit to a specialist can not be avoided. However, repairs will not be expensive. Therefore, one should take seriously the issue of originality of the memory device.

Tip # 2

Let's consider an example when the Nokia phone does not turn on. When you connect the memory device also does not give signs of "life". Most likely, the battery lost its starting momentum, which can be replenished in two ways:

• Put the phone for a while to recharge.
• Forcibly apply to the battery terminals 5-7 V.

The first option is not always effective - charging can not resume. The second way is fail-safe, however it requires some specialized knowledge, since the battery controller can be disabled. In this case, the battery should be discarded.

Reason # 3: Management Functionality

Virtually any portable communication device is equipped with a special Power button, which is responsible for starting the device. The miniature size of the switching element requires the user to be careful at the moment of pressing, as excessive physical force can simply disable the starting mechanism. And if you consider that in some models the trigger button is too tight, and its form factor is absolutely impractical, you can be sure that the question "Why does not the phone turn on?" Is just a matter of time. Therefore, when buying a device, pay attention to such a low-profile characteristic of the device as the convenience of pressing the "On" key.

Tip # 3

Replace the micro-button at home - a rather problematic task. Executable, of course, but "operation" requires some skills and the availability of special tools. In addition, not every phone is easily dismantled, often the structural features of the body part of the device when parsing even professionals create "problems". Remember this.

Reason # 4: Software failure

It's no secret that modern mobile phones are controlled by a specially designed software for them. The software of today's cellular device is as complex as the computer systems Windows, Mac OS or Linux. Therefore, we can assume that the launch of the phone is impossible due to any damage to the software part of the device. It is worth noting that the previously existing problem "Phone" Samsung "does not turn on" was eliminated relatively simply. With the help of a service cable and a freely available program on the Internet, everything was decided within a few minutes. Now, reprogramming the phone software is an incredibly difficult task. Since a common update is nothing compared to flashing the code of a modern mobile communication device. By the way, not every repairman for cellular phones is a specialist capable of restoring the working capacity of the software components of the phone.

Tip # 4

Diagnose the "collapse" of the mobile system is elementary. As a rule, the phone with the damaged software will be loaded only until the appearance of the corporate logo. Then the device can enter into a "stupor" or "hang". The most common failure is a cyclic reboot. Less often - absolute inaction. Paradoxically (since we all know about the excellent Japanese quality), nevertheless, the situation "Sony phone does not turn on" is quite a frequent phenomenon in the world of "software malfunction".

Reason # 5: Mechanical damage

When the phone strikes, the internal hardware components of the device may shift. A feature of microelectronics is the critical moment of positioning of parts, since compactness requires the use of a special assembly technology - the installation of chips on the BGA-balls (the kind of soldering). Restorative process requires special equipment. Only an experienced engineer can fix this kind of damage. Therefore, we will repeat: in order to diagnose and eliminate the "iron" malfunction, it is necessary to contact a service center or a specialized workshop.

Reason # 6: Environmental Impact: phone screen does not turn on

As you know, the liquid (in a critical amount) that gets inside the mobile device is, at best, a temporary loss of the capacity of the electrical components of the system. Oxygenates the parts, connectors, contacts of the cables, and at the same time the de-energized component or module breaks down, "blinding, deafening or obezvuchivaya" the functional of the mobile phone. It happens even worse - a global closure without recovery options. Since not always protection can in time work and de-energize the ways of distribution (in such a situation) of "destructive" electricity. By the way, in the recent past Koreans used a varistor protection scheme. Therefore, even after the device thoroughly heated, the repairman knew how to turn on the phone "Samsung". To do this, they removed all the varistors in the keyboard circuit, and the device worked again. However, already deprived of the protection system.

Condensate, static, high and low temperatures are all unfavorable factors of influence. Therefore, before you get the phone during rainy weather, think about what you are risking. However, an abrupt transition from a cold environment to a comfortable atmosphere at room temperature is also fraught with consequences in the form of condensate, both on the outside of the cellular device and on the internal components of the device.

Tip # 6

Try not to use your phone under adverse climatic conditions. Timely detection of traces of oxidation, whether it is a plaque of corrosion on one of the connectors or a darkening of the structural part of the body part of the device, will help prevent a disastrous scenario.

Finally

Now you know the main reasons why ordinary users often have a question: "Why does not the phone turn on?" Perhaps the material in this article will help you avoid many unforeseen life situations. Since today you probably learned that the instruction to any mobile phone is, first of all, a memo sharpening on small things, and after that - an obligatory element of the equipment of the production produced by the company. Enjoy and enjoy your communication!
