A fairly common problem is the lack of response to pressing the computer's power button. In other words, when you, as usual, try to turn on the computer by pressing the button, nothing happens. This article will describe the possible reasons for this behavior of the computer.

Causes

So, let's begin. Here is a list of possible reasons:

1. Lack of voltage in the electrical outlet;
2. Damage or non-contact of the power cable going from the outlet to the computer's power supply;
3. The power supply power button is off;
4. Breakage of the computer power button itself or its wires;
5. Failure of the power supply;
6. Failure of the motherboard.

The first thing to start with diagnosing this malfunction is to make sure that there is voltage in the electrical outlet. You don't have to do this with a tester. It is enough to include some other electrical device in it and make sure that it works.

Next, you need to check whether the black power cable is securely connected to the electrical outlet and to the power supply, and also to make an external examination for damage and fractures, especially at the ends of both connectors. To do this, pull the end out of the computer's power supply and insert it back.

The next step is to pay attention to the computer's power supply. To do this, look at the back of the system unit in the place where the power cable comes from the outlet.

If there is a button - switch, then it must be in the on state.

Power button on the power supply

After that, you need to try to start the computer without the power button.

Turn off the computer and remove the side cover of the system unit. Next, we are looking for a terminal block where the power button, restart, power and hard drive indicators are connected. It is usually located in the lower right corner of the board.

Location of the contact block on the motherboard of the computer power button

When we found her, we remove all contacts from her. To do this, we pull them up by the wires, having previously recorded or photographed their location.

Now we take a screwdriver, knife or other similar metal object and try to close the contacts with it, which are signed as "PWR_BTN" or "WP + WP-" or "PWR SW" by simply touching them with the screwdriver at the same time.

How to turn on a computer without a power button - close the contacts with a screwdriver

If you cannot find these contacts by the inscriptions under it, or you simply do not have inscriptions under them, then try to close all adjacent contacts in turn with a screwdriver.

If the computer still does not turn on, then the problem is not with the power button.

Now, to check the power supply, you need to try to install a knowingly working one, borrowing it from friends or acquaintances, or check your block on another computer.

If the power supply turns out to be intact, then the only remaining reason will be a non-working motherboard, which in most cases will have to be replaced, unless capacitors on it are corny and can be replaced.

This is how the swollen capacitors on the motherboard look like.

Even the most expensive smartphone is not immune to breakdowns. During operation, the device may fall to the floor, be damaged by water, and receive other mechanical damage.

As a result, individual controls may fail.

Practice shows that one of the most vulnerable points of a Samsung smartphone is the power button (on / off).

If the main phone button broke or stopped responding to pressing, only the master will help to correct the situation. However, you can use your smartphone for a while with the power button not working.

Turn on Samsung with a disabled button

There are several options for solving this problem, here are the most effective ones:

1. We put the smartphone on charge. Many models of Samsung phones and other manufacturers turn on when connected to a charger. The first thing that can be done in this case is put the device on charge and try to hold down the volume control key.

If you don't have a wall charger at hand, but you have a laptop and a USB cable, you can connect your phone to your computer.

2. If the first method fails, try hold down the volume button to the "-" position, the "home" button and, keeping these two buttons pressed, connect the power cable (do not release the buttons all the time!). After a few seconds (about 5-7) a warning menu should appear on the screen.

Necessary remove the back cover from the device, insert the power cable. When the second battery indicator appears, you must abruptly disconnect the power cable and also abruptly remove and insert the battery. The phone will start to reboot.

Turn on Samsung without a button using the Mobile Uncle application

It is not very convenient to turn on a Samsung phone without a power button every time using all of the above intricate methods, so after a successful launch, we recommend installing a special Mobile uncle tools 2017 application on your smartphone.

With this universal multi-tool, you can do almost anything with your Android device by completely changing the settings and functionality of the working buttons.

The Mobile Uncle app works with any device based on MTK processors.

There is another application - Power button to Volume Button (available for free in the Play Store) - it is designed specifically for such a case. It can be used to shift the function of the power button to the speaker volume keys.

There are only two active items in the application menu: Boot and Screen Off. It is enough to put a tick next to the "Boot" item and the smartphone will turn on using the volume rocker.

For example, the power button of a smartphone does not work. Crashed, broke, etc. And now the question arises, how to turn on the smartphone without this very button?

Old and new, expensive and cheap, on Android or iOS, trendy and not so - all smartphones and tablets can break.

Not in the sense of glitching and freezing, namely, fail, as a rule, as a result of sudden mechanical and other adverse effects. Sometimes -, but more often with less tragic consequences, one of which is just a mechanical failure, due to which the power button does not work.

It's a shame, annoying. It turns out that the device did not seem to have suffered much, but the sense from it suddenly became much less.

In fact, if you were "lucky", say, to drop your smartphone (or tablet) so delicately that it was the power button that got the most, then this adventure, as practice shows, can develop for you along two storylines: the smartphone remained turned on, but you cannot unlock it, or it turned off completely, and now it is not clear how to turn it on, since the power button does not work.

Actually, the conditions of the tasks are formulated. Now you can try to solve them. So:

how to turn on the smartphone, if it is turned off, the power button does not work

The current situation, of course, is not encouraging, but there is still hope. However, success is not guaranteed, since it will depend on the brand and model of a particular device.

First of all (and this option no. ) we try to connect the smartphone to a standard charger. This is in case it does not turn on due to battery discharge. Some models may automatically turn on at this stage (although, unfortunately, the likelihood of such a quick solution to the problem is extremely low). We connect to the charger and hold down the volume control button for a while, suddenly the boot menu appears on the smartphone screen.

Option number 2 ... If the battery is not completely discharged (at least 5%, or better, more, the charge indicator is displayed even if the smartphone is turned off), disconnect the device from the mains charger and connect it to a computer or laptop via ... Our Motorola Moto G then turned on instantly without any buttons.

If yours has not turned on, then there is still option number 3 ... To be fair, let's call it a chance. Since it can only work if, before turning off the smartphone, you activated the USB debugging mode on it, and now you can try to turn on the device through the command line of the computer. In general, if the conditions are met, then install ADB on the computer and open a window with a command line. After that, we connect the smartphone via USB, write in the command line adb reboot and click Enter.

how to turn on the smartphone if the screen is locked and the power button does not work

As they say, already lucky, so lucky. If the power button stopped working, but the smartphone did not turn off, then everything is somewhat simpler. But you still have to be quick and turn off the screen of the device so as not to waste the battery charge in vain (just in case).

Owners of Samsung Galaxy and iPhones shouldn't be very nervous at all, because even with a smashed power button, they can then unlock their smartphones and ... In addition, many modern models, including those for which the Home button is not provided by the design, can be woken up by tapping twice on the screen (of course, if this option is active).

It's another matter when there is no Home, and the screen does not want to turn on (or cannot). Then you need to either connect your smartphone to the charger, or ask someone to call it. Also. if the power button does not work, you can press the physical camera key, if there is one, thus launch the corresponding application, and then simply exit this program to the main menu. It is not very convenient, but then you can download a suitable program to quickly unlock the screen, which will significantly simplify the problem for a while. The main thing is not to forget about the battery level in all this fuss.

For example, the application Power button to Volume Button Allows you to emergency transfer the function of the power button to the sound control button; with Gravity screen the smartphone turns off automatically if you put it on a flat surface or in your pocket, and turns on if you take it in your hand; Shake Screen On Off - the screen can be turned on / off by simply shaking the smartphone slightly if the power button does not work. This should be enough for the time until you get to the nearest service center.

Whether it's old or new gadgets, they break, and smartphones are no exception. A simple fall onto a hard surface is enough to cause damage.

Smartphones are fragile in nature. Even if they don't break, they are prone to many problems. One such problem, which is very common among Android users, is when the power button stops working.

Think about it, the power button - the button we press countless times a day - stops working. This is enough to create chaos in our lives. When you press the button again and again - which is to be expected - it will stop working one day.
This does not happen to everyone, but those who encounter this problem know how it complicates the operation of the phone. Here are some solutions for this annoying problem.

1. Automation on / off function with Gravity Screen.

Gravity Screen is an awesome app. Using different phone sensors turns the screen on and off. A feature such as a pocket or table sensor sensor is designed to detect when you are holding your phone and when not. It learns to understand when you are going to use the phone, and according to this, turns it on or off, to be honest, it always works, but the accuracy can vary from device to device.

If you're not particularly interested in how the app works and you just want it to turn your phone on and off, then go ahead and download it and it will work great without over-draining your battery if you set it up correctly.

2. Moto display

The app is limited in that it can only be used by owners of Motorola devices, but we had to add it to the list because it's just awesome.
In Moto display, you can see notifications without turning on the phone. But it can be used for more than just viewing notifications. Just don't touch your phone for a few seconds, then pick it up and you will see the Moto display turn on. At this point, you can swipe down towards the lock icon to unlock it. Works great.

Moto dispay does not block the phone, it must be done manually. But since the power button does not work, we recommend setting the phone sleep time to a minimum, that is, 15 seconds.

3. Transfer the Power On / Off to the volume button

Yes, you read that right, there is an app for that too, and the best thing is that it works even if the phone is not rooted. This application is called Volume Unlock Power Button Fix, that is, “unlock the volume, fix the power key”. This is a very, very long name, but it completely defines the purpose of the application.

First of all, install it on your phone. Now open the application and give it administrator rights. This is necessary, otherwise the application will not work. Open the app and turn on "Enable Volume Unlock" and "Screen off" using the switches on the right. If you have both options enabled, then you can turn off the screen in the notification panel and turn it on using the volume button.
In the app's settings, you can also enable features such as auto-start at boot and auto-enable / disable, which will run at a set time interval. For example, by setting the time from 06:00 to 04:00, the application will function only during this time.
We have been using it for 2 days and have not found any unnecessary draining of the battery. This is an amazing app.
