As a rule, Murphy's law works at the most inopportune moments of our lives. In addition, modern means of communication, namely mobile phones, can hardly be considered faultless in full. 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 does the phone not turn on?” is a great example of this. Let's take a closer look at the causal sources of a mildly unfavorable situation: the failure of a mobile phone to start when the user activates the "correct" "On" button.
Calm, only calmness…
First of all, don't panic. You may be pressing the wrong button! It is likely that you simply ignored the user manual for the phone, that is, you did not read it. As a result, banal ignorance of the purpose of a particular keydevice 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" key in the operating mode of the device activates the "lock" command. The screen turns off and the phone goes into standby mode. At such moments, it may seem to an inexperienced user that the mobile phone has turned off, and not knowing how to unlock it is fraught with loss of not only time, but also nerves. In new modifications of mobile devices, an almost intelligently controlled blocking scheme is used. Therefore, the user manual of the phone is an important document that requires careful study.
Main reasons for mobile phone not turning on
So, the manufacturer of the cellular device supplies you with the necessary information in the form of some instructions. Many underestimate the important nature of the attached document. Which, in general, is not entirely correct and even inexcusable, given the considerable cost of some modifications of mobile devices. Practice shows that the instructions are simply ignored, at best, the user only superficially runs through the text of practical recommendations. As a result, the rows of "thirsty" answers to the question "Why does not the phone turn on?" are inexorably replenished, and the popularity of the problem is gaining actual weight.
Tip 1
You won't believe it, but by spending a few minutes studying the instructions for the phone, you will significantly expand your knowledge base, moreover, many difficultiesresolved almost immediately. The main thing is that you protect your device from unjustified operational errors, which are made by those who did 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 of starting the device, the charge indicator showed the full amount of the battery, the phone turns 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 confuse the user … As a result, a person changes the battery. However, such a “treatment” does not always correct the situation. Typically, the signs of a bad battery are:
- Spontaneous battery heating.
- Swelling of the capacitive chamber of the battery.
- Short charge to full capacity.
In such cases, it is really necessary to replace the energy element of the mobile communication device.
Reason 2: Charger
Original charger performs "refueling" in the most gentle way. That is, the charge occurs without jumps and voltage drops. The “filling” mode of the battery capacities is stable, the current strength and voltage are supplied in the values specifically provided by the manufacturer. In the event that the charger does not quite correctly deliver electrical energy to the hardware of the mobile phone, there is a high riskthe fact that the power controller of the device will simply fail. By the way, in this case, a visit to a specialist cannot be avoided. However, the repair will be expensive. Therefore, it is worth taking the question of the originality of the memory more seriously.
Tip 2
Consider an example when the Nokia phone does not turn on. When the charger is connected, the device also does not show signs of "life". Most likely, the battery has lost its starting impulse, which can be replenished in two ways:
- Put the phone on charge for a while.
- Forcibly apply 5-7 V power to the battery terminals.
The first option is not always effective - charging may not resume. The second method is trouble-free, but requires some specialized knowledge, since the battery controller can be disabled. In this case, the battery will have to be thrown away.
Reason 3: Control functionality
Almost any portable communication device is equipped with a special Power button, which is responsible for starting the device. The miniature dimensions of the switching element require the user to be careful at the moment of pressing, since excessive physical force can simply disable the starting mechanism. And given that in some models the start 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?" - just a matter of time. Therefore, when buying a device, pay attention to such an unremarkable characteristic of the device,like the convenience of pressing the "On" key.
Tip 3
Replacing a microbutton at home is a rather problematic task. Doable, of course, but the "operation" requires some skills and special tools. In addition, not every phone can be easily dismantled, often the design features of the body part of the device create “problems” even for professionals when disassembling. Keep this in mind.
Reason 4: Software failure
It's no secret that modern mobile phones are controlled by software specially created for them. The software of today's cellular device is as complex as Windows, Mac OS or Linux computer systems. Therefore, it can be assumed 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 "Samsung phone does not turn on" was eliminated relatively simply. With the help of a service cable and a program freely distributed on the Internet, everything was solved within a few minutes. Now, reprogramming phone software is an incredibly difficult task. Since a generally accepted update is nothing compared to flashing the program code of a modern mobile communication device. By the way, not every cell phone repairman is a specialist capable of restoring the functionality of the phone's software components.
Tip 4
Diagnose the "crash" of the mobile systemelementary. As a rule, a phone with corrupted software will boot only until the company logo appears. Further, the device may enter into a "stupor" or "hang". Most often there is an inconclusive cyclic reboot. Less often - absolute inaction. Paradoxically (after all, we all know about the excellent Japanese quality), nevertheless, the “Sony phone does not turn on” situation is a fairly common occurrence in the world of “software failure”.
Reason 5: Mechanical Damage
If the phone is hit, the internal hardware components of the device may be dislodged. A feature of microelectronics is the critical moment of positioning parts, since compactness requires the use of a special assembly technology - landing microcircuits on BGA balls (a type of soldering). The recovery process requires special equipment. Only an experienced engineer can repair this kind of damage. Therefore, we repeat: in order to diagnose and eliminate an “iron” malfunction, you must contact a service center or a specialized workshop.
Reason 6: Environmental Issues: Phone Screen Won't Turn On
As you know, liquid (in a critical amount) that got inside a mobile device is, at best, a temporary loss of efficiency of the electrical components of the system. Parts, connectors, loop contacts are oxidized, and at the same time, a de-energized component or module fails, “blinding, deafening or mute” functionalitymobile phone. It happens even worse - a global closure without recovery options. Since the protection can not always work in time and de-energize the distribution paths (in such a situation) of “destructive” electricity. By the way, in the recent past, the Koreans used a varistor protection circuit. Therefore, even after the device was thoroughly drowned, the repairmen knew how to turn on the Samsung phone. To do this, they removed all the varistors in the keyboard circuit, and the device worked again. However, already deprived of the protection system.
Condensation, static, high and low temperatures are all adverse factors. Therefore, before you take out your phone during rainy weather, think about what you are risking. However, a sharp transition from a cold environment to a comfortable room temperature atmosphere is also fraught with consequences in the form of condensation, both on the outside of the cellular device and on the internal components of the device.
Tip 6
Try not to use your phone in adverse weather conditions. Timely detection of traces of oxidation, whether it is corrosion on one of the connectors or darkening of a structural part of the body of the device, will help prevent a harmful scenario.
In conclusion
Now you know the main reasons why ordinary users often have the question: “Why does the phone not turn on?” Perhaps the material in this article will help you avoid many unforeseen life situations. Because today you must have learned,that the manual for any mobile phone is, first of all, a memo pointing to trifles, and only after that it is an obligatory element of the complete set of products manufactured by the company. Have a pleasant and fruitful communication!
