I did this on two machines - I used the "Reset" button, it's still not really needed.

The computer power button is connected to the power supply. It simply closes the circuit for a short time (without fixing this circuit), which starts the power supply, i.e., working supply voltages appear at its output (power supply) and the computer starts accordingly. This is not an emergency, but a minor nuisance. In fact, only a Soviet-made cast-iron frying pan can be more reliable than a computer power button (there is nothing to break there). Here you only need to change the button.

Open the system block. Find to which contact on the motherboard the wiring labeled power goes, and carefully close these contacts for a short time with a paper clip or screwdriver so as not to turn on the computer every time - it is advisable to simply change the button to any other from any computer case.
Modern cases look quite attractive, menacing, aggressive, unusual... The developers have enough imagination, which means that ordinary buyers can choose from a huge range. But not only do the current cases have an attractive appearance, they also have "working" pluses. Such pluses are USB connectors, as well as microphone and headphone jacks on the front of the case, and this in turn means that every time we need to connect a USB flash drive, we need to climb under the table and get to the back of the case. I think everyone agrees that these are, in principle, trifles, but still, it’s more pleasant to just insert a USB flash drive in front and start working.
But, unfortunately, there are cases when some parts of the computer case fail. It's about the famous POWER button, which is absolutely on every case. In the process of long operation, this button can simply fail, for example, stop being pressed or vice versa, it will fall deep into the case, and no matter how you “conjure”, you won’t be able to turn on the computer. What to do in such situations? If you don’t really need a computer, then it’s better to call the master and wait with peace of mind until he repairs everything, paying him a certain amount of money for this.
If you need to use the computer urgently enough, then perhaps you should use the following advice.
First you need to find a flat surface and carefully place the system unit so that the left cover looks at you, while you should not disconnect all the wires in order to complete everything faster, but you should make sure that these wires are not stretched. In addition, a prerequisite should be that the computer is disconnected from the power supply, as they say, you never know. The next thing to do is remove the left case cover. In modern cases, this usually does not require any great effort, so this should not be a problem.
After removing the cover, an amazing picture will appear in front of you. You will see everything for which you once gave a round sum, and which usually works peacefully, making an innocent noise, and what now does not want to “start up”. Our focus should be primarily on the multi-colored wires that run from the front of the case to the motherboard. There can be many such wires, and it is not surprising, because there are connected and POWER buttons And RESET button, and USB ports, together as audio outputs. So, at the next step, we may need a little knowledge of English, which many received at school, because on the wiring itself, as well as on the motherboard, near the connection of these wiring, it should be written what they mean. Take the USB ports as an example. On the motherboard itself, near the connection, there should be an inscription USB1, USB2, etc. This means that the wires connected to these connectors are nothing but USB connection ports.
But do not forget about our problem, which means that we need to look for posting POWER(usually these are two wires woven together). Typically, the connectors to which the power or reset buttons are connected are located on the lower right side of the motherboard:
On most motherboards, these connectors are the same and consist of 9 pins arranged in two rows. The last two contacts in a short row of 4 plugs are responsible for turning on / off the computer.
Here are the connector diagrams for the most popular motherboard manufacturers.
MSI
AsRock
Asus
Biostar
Epox
foxconn
gigabyte
Intel
When these two wires are found, you should find where they are connected to the motherboard. After the connection point has been found, it is worth carefully disconnecting these wires, so that the small plugs are exposed.
That's it, now we're almost done. The final step is only turning on the computer, for this we need an ordinary stationery pen, preferably one that writes in bold. After finding such a pen, you can connect the computer to the power supply, and then gently run the tip of the rod over these bare needles. Or in other words, you just need to close these contacts. After these steps, the computer should come to life, and the download will begin. If nothing happened, then it is worth repeating the procedure, but close these needles quickly enough.
Thanks to such simple steps, you can start the computer without any problems, but this should not be neglected, and it is better to fix the start button on the case as soon as possible in order to avoid unnecessary problems.
Attention: Neither the author of this article, nor the administration of this site, bears any responsibility for possible problems that may arise in the process of turning on the computer in this way. You will perform all of the above actions at your own peril and risk, and will be solely responsible for possible problems that are not described in this article.
Even the most expensive smartphone is not immune from breakdowns. During operation, the device may fall to the floor, suffer from exposure to water, and receive other mechanical damage.
As a result, individual controls may fail.
Practice shows that one of the most vulnerable places on a Samsung smartphone is the power button (on / off).
If the main the phone button is broken or stopped responding to pressing, only the master will help to correct the situation. However, for some time you can use your smartphone with a broken power button.
Turn on Samsung with a broken button
There are several options for solving this problem, here are the most effective ones:
1. We put the smartphone on charge. Many Samsung and other phone models turn on when connected to a charger. The first thing to do in this case is put the device on charge and try to hold down the volume control key.
If you do not have a wall charger at hand, but have a laptop and a USB cable, you can connect your phone to a computer.
2. If the first method did not work, try press 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.
Need to remove the back cover from the device, insert the power cable. When the second battery indicator appears, 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
Every time turning on a Samsung phone without a power button in all the intricate ways listed above is not very convenient, therefore, after a successful launch, we recommend installing the special application Mobile uncle tools 2017 (Mobile Uncle) 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 application 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 this case. With it, you can 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 check the box next to the “Boot” item and the smartphone will turn on using the volume rocker.
Any device is subject to physical wear and tear, as a result of which it may stop working. This also applies to desktop computers, with which some problems constantly arise. Very often, the power button fails in system units, without which it is very difficult to start the computer. So what to do in a situation where you pressed the power button, and nothing happened in response?
general information
Sometimes a situation arises in which it is impossible to turn on a stationary PC. At the same time, there is power in the network, an LED is lit on the system board, which signals its operability, however, the device does not react in any way to pressing the power button. Most likely, this is due to its failure. So what to do in such a situation and is it possible to somehow start the computer?
Such a breakdown can be associated with a huge number of factors, some of which can be eliminated on your own, while others may require the help of professionals. This article will discuss the most common causes of failure, methods for their elimination, as well as some ways to start the system unit without a power button.
Diagnostics
The system unit is a very complex device, consisting of various components, each of which can fail. Therefore, if you encounter any problem, the first thing to do is to try to understand what the problem is. The power supply unit is responsible for powering the system unit, which is very sensitive to voltage drops. Thus, the diagnosis of a malfunction should begin with it. To do this, disconnect all PSU wires from the system board, optical drive, hard drive and graphics adapter. Next, using a paper clip, you need to close two contacts on the widest adapter, which is responsible for supplying power to the motherboard. In most PSU models, these contacts are green and black. If, after a short circuit, the cooling cooler of the power supply does not start, then this indicates the failure of the device. If everything worked, then most likely the problem lies in the power button.
How to turn on a PC without a button?
If the start button on your system unit is broken, then do not despair, because the computer can be turned on without it. The power button is on the front panel, which connects to the system board. On the motherboard for connecting the panel, special connectors are provided, which are located in its lower right corner and have the Power Switch signature. When you find this connector, you need to disconnect all wires from it, after which you need to close two contacts signed PWR SW with a screwdriver.
If, after performing the steps described above, the system unit starts up, then the problem really lies in the power button. You can fix this problem in several ways:
— to make a complete replacement of the power button;
- connect the reset button to the power connectors;
- take the computer for repair to a service center.
The best option would be to completely replace the worn button, since without it it will not be possible to operate the computer normally. After all, you must admit that every time climbing into the system unit to turn on the PC is not very convenient. If you do not have the necessary experience, then it is better not to risk it, but to turn to professionals for help.
Using the keyboard
The keyboard is one of the most efficient devices that allows you to interact with your computer and use all its features. In addition, not all users are aware that using this device, you can not only turn off the PC, but also turn it on. However, it should be noted right away that only a PS / 2 keyboard is suitable for inclusion. More modern models that use the USB connector for synchronization with the system unit will not allow you to implement your plan.
If you have an input device with the required interface at your disposal, then in order to control the power of the computer with it, you will need to configure the hot keys. To do this, you can use both single keys and their combinations. For example, it can be a space or Ctrl+Esc. After saving the changes made to the settings and restarting the computer, all changes will take effect.
For the settings, you will need to enter the BIOS using the standard key, after which you need to go to the Power Management Setup tab, where you will need to set the default keyboard, in the line for selecting a device to start. This will solve the problem of turning on the computer when the power button is out of order, without replacing it.
Design features
The power button has a very fragile design, so it often fails. If at the same time a cheap Chinese-made system unit was bought, then the power button may have an even shorter service life and fail much earlier. Therefore, when buying a ready-made desktop system or self-assembly of a computer by components, it is necessary to pay great attention to the quality of all elements and components of the PC, so as not to regret the choice later. Today, there are many brands on the computer components market that produce high-quality cases and power supplies, so there will be no problems with the choice.
Precautions for Diagnosis and Repair
If you decide to troubleshoot and repair the system unit yourself, without the help of a professional, then you must follow the basic safety rules so as not only not to suffer yourself, but also not to cause even more harm to the computer. The main requirement when performing any work is the complete de-energization of the system unit. To do this, disconnect the power cable from the mains. This must be done even if the power supply has a special button for de-energizing.
This simple rule will avoid many unpleasant situations. The current, of course, will not hit you, but imagine what will happen to your fingers if the system unit starts up, and at that moment you accidentally put them in a cooling fan? Or you unscrew the bolts, and one of them will fall on the motherboard and short out something, as a result of which the motherboard or some other device may burn out.
In conclusion
So, if you have read the article up to this point, it means not only that it has come to an end, but also that now you know how to determine the malfunction of the computer power button, repair it, and also know how to start the PC without this buttons. Finally, it is worth noting that the article considered only basic measures to eliminate this problem. There are several other ways to fix the problem with the power button, however, they require the user to have certain skills and experience with electronics, so it will be quite difficult for novice users to deal with them. To never have problems with a computer, assemble the system unit exclusively from high-quality components.
It is very annoying if the power button (Power Button) is faulty, but in this case, it is not necessary to run to the store for a new smartphone or tablet. Now we will talk about how you can turn on your smartphone without pressing the button.
There are many different ways to turn off and even turn on the device without using the power button.
Depending on the period of use, sometimes smartphones and tablets break down. One of the most common problems is a faulty power button. After all, a gadget is useless if it cannot be turned on, right?
How to turn on a phone with a broken power button
This situation has two possible options: the smartphone or tablet is turned on, but the display cannot be turned on, or the gadget is turned off, and the smartphone cannot be turned on due to problems with the button. Let's consider each option separately.
Device turned off
If the shutdown button is faulty, while the device is turned off, there is little chance that something can be done, but there is hope. Solutions vary depending on the design and model of the device.
First you need to try to connect a charger to the gadget if the battery is low. Some models turn on automatically during charging, it is unlikely that you have come across this one, so we press and hold the volume buttons until the boot menu appears.
You can also try connecting the gadget to a PC or laptop via a USB cable (provided that the battery charge is 5 percent or more). We tested this method on the Motorola Moto G - the smartphone immediately turned on.
If USB debugging mode was enabled before turning off the device, you can use the command line. Install the Android Debug Bridge program (Android debug bridge) and open a window for entering commands. Next, enter the following command without quotes: “ adb reboot" or " adb reboot recovery" and press "Enter".
Device enabled
Those who encountered a non-working power button on the switched on device were more fortunate. In this case, it is important to prevent the device from turning off, that is, make sure that the charge does not drop to zero.
On some smartphones like the Samsung Galaxy and iPhones, a broken power button isn't a problem, as you can turn on the display by pressing the home button. Alternatively, you can try double tapping the display.
You should also connect your smartphone to the charger or ask someone to call it. If the case has a button to turn on the camera, click on it, go to the "Camera" application, then exit to the main screen.
The methods described above may not be suitable for owners of some gadgets, so it will not be superfluous to download an application in advance with which you can unlock the device's display.
Application
The Power button to Volume Button application is designed just for this case, with the help of it you can shift the function of the power button to the volume buttons. There is one more - Gravity Screen, it allows you to set the smartphone to automatically go to sleep if the device is face down, and “wake up” when taken in hand. And with the Proximity Actions app, which uses the device's proximity sensor, it's also possible to wake the device from hibernation through gestures. Shake Screen On Off is from the same series. Anyone, even an inexperienced user, can understand all these applications.
And do not forget to monitor the battery charge in order to avoid shutdown.
