As a rule, as a result of some unwanted external influence (or for other reasons), the power button on a mobile device may stop performing its function. Then the question arises, how to turn on the phone without the Android power button.
The situation, of course, is not pleasant, but not hopeless. Solving the problem in order to get the necessary information, or even using the smartphone for a while, is quite possible. This is what we will talk about now.
There are several options to correct an unpleasant situation, we will consider them further, and all you have to do is choose what is suitable in your case. But, you need to understand that no one gives a 100% guarantee; a lot depends on the brand and model of the gadget, the causes of the breakdown and the depth of the problem. So, let's try.
We start the smartphone if it is turned off and the power button does not work
Method one
First you need to try connecting your phone to a standard charger. Some models may start already at this stage. So, we connect to the charger and try to hold down the volume control key, it is quite possible that after this we will see the boot menu on the smartphone display. 
Method two
If we are lucky and the battery is not completely discharged, then you just need to disconnect your smartphone from the mains charger and connect to your PC using a USB cable.
Method three
If the “USB debugging” mode was enabled on the device, you can try to turn on the phone using the computer command line. What do we need to do in this case.
Install on PC A.D.B., after which we need to open a command line window, connect our device via USB, and on the command line enter adb reboot and press Enter.
*Note: ADB is a desktop console application. It allows you to debug Android devices as well as emulators.
If the power button does not work and the screen is locked
In this case, you need to worry about saving battery power. On Samsung Galaxy, you can unlock the device with the “Home” button. The same function is available on some modern models. You can also “wake up” your smartphone by double tapping on the screen if this option is active.
You can also call the phone from another device, or if you have a physical camera button, try to launch the application of the same name, and from there enter the main menu.
We will look at the next method in the video. In this case, you will need to disassemble the smartphone and close two contacts:
Using special applications
If you managed to start your device without a power button using one of the suggested methods, then you can install one of the special utilities that will help you safely use a gadget with an inoperative button. Let's look at some options.
An excellent application that will be convenient not only in a critical situation. We set the parameters that are comfortable for ourselves and our smartphone will turn off when it is lying on a flat surface or in a pocket, and turn on when you just pick it up:
In an emergency, this utility will transfer the on/off function to the volume button:
Another software that will be useful in the described situation. With its help, we can easily shake our smartphone on or off.
For example, the power button on your smartphone does not work. It 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, fashionable and not so fashionable - all smartphones and tablets can break.
Not in the sense of glitching and freezing, but rather, failing, as a rule, as a result of sudden mechanical and other unfavorable influences. Sometimes - but more often with less tragic consequences, one of which is a mechanical breakdown due to which the power button does not work.
It's embarrassing, annoying. It turns out that the device didn’t seem to have suffered much, but it suddenly became much less useful.
In fact, if you are “lucky”, say, to drop your smartphone (or tablet) so delicately that it was the power button that got the most damage, then further this adventure, as practice shows, can develop for you along two storylines: the smartphone remains turned on, but you can’t unlock it, or it turned off completely, and now it’s unclear how to turn it on, since the power button doesn’t work.
Actually, the conditions of the tasks are formulated. Now you can try to solve them. So:
how to turn on a smartphone if it is turned off and 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. Time ) we try to connect the smartphone to a standard charger. This is in case it does not turn on due to a low battery. Some models may turn on automatically 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 button for a while, suddenly the boot menu appears on the smartphone screen.
Option No. 2 . If the battery is not completely discharged (at least 5%, and preferably more, the charge indicator is displayed even if the smartphone is turned off), disconnect the device from the mains charger and connect it to the computer or laptop via . Our Motorola Moto G then turned on instantly without any buttons.
If yours doesn't turn on, there is still option No. 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 computer command line. In general, if the conditions match, then install ADB on your computer and open a command line window. After that, connect the smartphone via USB, and write in the command line adb reboot and click Enter.
how to turn on your smartphone if the screen is locked and the power button does not work
As they say, I was so lucky. If the power button stops working, but the smartphone does not turn off, then everything is somewhat simpler. But you still have to be quick and turn off the device’s screen so as not to waste the battery charge in vain (just in case).
Owners of Samsung Galaxy and iPhones don’t have to be too nervous at all, because even with the power button smashed to smithereens, they can then unlock their smartphones and . In addition, many modern models, including those that do not have a Home button, can be woken up by double-tapping 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 the 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. This 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 in all this fuss about the battery level.
For example, application Power button to volume button allows you to emergency transfer the function of the power button to the volume control button; With Gravity Screen The smartphone automatically turns off 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 lightly if the power button does not work. This should be enough until you get to the nearest service center.
Sometimes users complain that the power button on their phone does not work. Why does this happen? How to fix the situation? How dangerous is this phenomenon? All this will be discussed further below. It's actually simple to understand. Especially if the power button is to blame.
Battery
The first scenario occurs quite often. Moreover, it has nothing to do with the breakdown. Why doesn't the power button on my phone work? The culprit may be the device's ordinary battery. The thing is that insufficient battery charge renders the smartphone inoperative.
Because of this, it turns out that the power button does not work. Actually this is not true. It is enough to turn on the phone to the network for a few minutes, and then try again to work with the equipment. If the problem lies in a low battery charge, then everything will work.
real damage
But this is just the beginning. In fact, many users confuse situations in which the power button on their phone does not work, and when the device simply does not turn on. In principle, the result is the same - the gadget becomes a useless piece of plastic and iron.
In some cases, the power button may actually break. This is a very common problem. It occurs mainly in those who either work carelessly with the device, or use it for a long time. It's all due to normal wear and tear.
If the problem really is a breakdown, you can repair your mobile phone. Repairs are carried out in specialized centers. As a rule, for a fee you can pick up a working smartphone with normally functioning buttons.
Sometimes equipment cannot be repaired. What then? If the power button on your phone is broken, so much so that it cannot be restored to functionality, you will have to buy a new gadget. Fortunately, such a situation does not occur too often. Usually, you can easily contact a service center to have your phone repaired.
Software problems
Is the power button on your phone not working? As already mentioned, users often confuse a malfunction of the smartphone and a breakdown of the gadget’s control buttons. The second scenario is exclusively mechanical damage. Usually they are either corrected in service centers or lead to the need to purchase a new phone.
If we consider the problem not as a failure of the power button to work, but as the fact that the smartphone itself does not work, the reasons may lie, for example, in software failures. For example, the phone settings get lost under some circumstances. Or viruses damage the gadget's OS. Then it won't turn on. Or it will constantly turn off. In this case, the power button will also not work, nor will it respond to sent commands.
If there is a suspicion of a software failure, the situation is resolved in several ways. Namely:
- Phone flashing. This can be done either independently or at service centers. It is better for novice users to entrust their mobile phone to professionals. Repairs, expressed by firmware, are carried out in a few minutes. The gadget will work at full capacity.
- Configuring already turned on equipment. Usually, users themselves carry out the so-called “Hard Reset”, and then begin to adjust the operation of the device. The power button should work after resetting the phone parameters to the initial level.
- Checking your smartphone for viruses and further getting rid of malware. If the gadget has already turned off and it turns out that the power button on the phone does not work, it is best to take the equipment to a service center. They will quickly help you rectify the situation.
All this helps with failures caused by the phone's operating system or its software. But that's not all. It is necessary to get acquainted with other options for the development of events.
External influence
Why else might the power button on your phone not seem to work? It is likely that the device was subject to negative external influence. And this led to either system failures or hardware damage. Because of this, the power button may actually not work.
For example, the phone was dropped into water. Or the gadget fell from a height to the floor. These reasons lead to damage to the smartphone. And it stops working. In the first case, you need to disassemble the phone as soon as possible and dry its components. After that, reassemble and try to turn it on. In the second case, it is better to immediately contact the service center if you discover a malfunction of the phone’s navigation buttons.
Results
What conclusions can be drawn? The power button on the phone often does not work because the gadget itself refuses to function. The most common reasons for this behavior are:
- mechanical damage;
- manufacturing defect;
- external negative impact on the phone;
- low battery charge;
- viruses on the phone;
- system failure;
- need for flashing.
If you find problems turning on the phone, it is recommended to charge the battery, try to use the smartphone again, and then take the device to a service center. This is the most reliable way to repair equipment.
If your power button is broken and you're trying to turn on your phone, it's unlikely to work, but we can help. Today we will tell you how to turn on or wake up your phone without the power button.
Regardless of whether your smartphone is old or new, these devices sometimes break down. One of the most common and annoying defects is the Power Button not working. After all, if you can't turn the device on, it's no more useful than, say, a paperweight. In this case, you cannot avoid going to the nearest workshop, and it is better to entrust the repair of Sony xperia z or other Sony products to a branded service center.
If you're in this situation, there are two possible options: your phone or tablet is on but you can't wake it up, or it's completely turned off and you can't boot it up. We will tell you how to solve both of these problems, separately, below.
How to turn on your phone without the power button: the device is turned off
If your power button is broken and your device is turned off, then you are in a difficult position, but there is still hope. Different methods will work depending on the device model, so we do not make any guarantees.
The first and easiest way to try is to connect your phone to a charger, in case the battery runs out. Some phones may turn on immediately at this point, but this is unlikely, so try using a long press on the volume buttons to bring up the boot menu.
Once the battery is slightly charged, preferably 5 percent or more (the screen should show the percentage even if the phone is turned off), try unplugging it from the charger and connecting it to your PC or laptop via USB. We tried this with a Motorola Moto G and the phone booted up instantly.
Another option will work if you enabled USB debugging before the device was turned off. It involves using the command line. Install the ADB program on your PC and open a command prompt window (instructions can be found on our website). Once you have done this, connect your smartphone to your computer, type “adb reboot” and press enter.
How to turn on your phone without the power button: the device is turned on
If you are lucky and your device is still turned on but the power button is not working, then everything will be much simpler. For starters, don't let your phone or tablet turn off due to battery drain.
For some phones, such as Samsung Galaxy or iPhones, a broken power button will not cause significant inconvenience because the physical button Home under the screen will wake up the smartphone. Depending on the device, you may also be able to wake up your phone by double tapping the screen. However, most Android smartphones do not have physical control keys, so there is no way to wake them up.
There are several ways to force your phone to wake up without using the power button. Try simply plugging it into a charger or asking someone to call you. If you have a physical camera shutter button, you can use it to launch the camera app and then simply exit it.
Not all of these methods are convenient for waking up your phone without the power button, but once you turn it on, install an application that will help you in the future. But still, remember that you should not allow the device to turn off due to low battery.
The Power Button to Volume Button app does exactly what you'd expect from its name. Another app, Gravity Screen, will put your device to sleep when you place it face down on a flat surface and turn it on when you pick up your smartphone. As an alternative, consider Proximity Actions, which will control your phone using its proximity sensor.
At some point, it may happen that the power key of your Android phone or tablet fails. Today we will tell you what to do if such a device needs to be turned on.
There are several methods for starting a device without a power button, but they depend on how exactly the device is turned off: completely turned off or in sleep mode. In the first case, coping with the problem will be more difficult, in the second, it will be easier. Let's consider the options in order.
Option 1: Completely switched off device
If your device is turned off, you can start it using recovery mode or ADB.
Recovery
If your smartphone or tablet is turned off (for example, after the battery is low), you can try to activate it by entering recovery mode. It's done like this.
Wait until the system boots and either use the device or use the programs described below to remap the power button.
If you know for sure that USB debugging is disabled, then use the recovery method. If debugging is active, you can proceed with the steps described below.
In addition to command line control, the ADB Run application is also available, which allows you to automate the procedures for working with Android Debug Bridge. With its help, you can also force the device to reboot with a faulty power button.
Both recovery and ADB are not a complete solution to the problem: these methods allow you to start the device, but it may enter sleep mode. Let's look at how to wake up the device if this happens.
Option 2: Device in sleep mode
If your phone or tablet has entered sleep mode and the power button is damaged, you can start the device in the following ways.
Connect to charger or PC
The most versatile way. Almost all Android devices wake up from sleep mode if you connect them to a charger. This statement is also true for connecting to a computer or laptop via USB. However, you should not abuse this method: firstly, the connection socket on the device may fail; secondly, constant connection/disconnection to the power supply negatively affects the condition of the battery.
Call to the device
When receiving an incoming call (regular or Internet telephony), the smartphone or tablet wakes up from sleep mode. This method is more convenient than the previous one, but it is not very elegant, and it is not always feasible.
Wake up with a tap on the screen
Some devices (for example, from LG, ASUS) have a wake-up function by touching the screen: double-tap it with your finger and the phone will wake up from sleep mode. Unfortunately, implementing such an option on unsupported devices is not easy.
Power button remapping
The best way out of the situation (apart from replacing the button, of course) would be to transfer its functions to any other button. These include all kinds of programmable keys (like calling the Bixby voice assistant on the latest Samsung) or volume buttons. We will leave the issue with programmable keys for another article, but now we will look at the Power Button to Volume Button application.
Note that on Xiaomi devices, you may need to commit the app to memory to avoid being disabled by the process manager.
Wake up by sensor
If the method described above does not suit you for some reason, there are applications at your disposal that allow you to control the device using sensors: accelerometer, gyroscope or proximity sensor. The most popular solution for this is Gravity Screen.
Despite its great capabilities, the application has several significant drawbacks. The first is the limitations of the free version. The second is increased battery consumption due to the constant use of sensors. Third, some options are not supported on some devices, and other features may require root access.
Conclusion
As you can see, you can still continue to use a device with a faulty power button. At the same time, we note that no solution is ideal, so we recommend that, if possible, you still replace the button yourself or by contacting a service center.
