How to turn on the computer without the power button if it is broken?

Those who have computers for a long time often complain about some problems. One of them is the malfunction of the power button. Periodically, they refuse for good, and then the question becomes urgent: how to turn on the computer without the power button?

general information

Sometimes it happens that the power is present in the network, the motherboard is signaled by its LED, but nothing happens when the power button is pressed. The computer simply does not turn on! What to do in this case? How to turn on the computer without the power button and preferably not very difficult way?

It should be noted that the reasons for this behavior of technology can be extremely great. Within the framework of the article, several most popular variants of failure and their elimination will be considered. Will be given those that can easily be repeated at home. If none of the below is available, then it would be better to contact the professionals so that they can resolve the problem.

Fast, but complex verification

Initially, it is necessary to check the operation of the power supply:

1. To do this, first unplug all connectors (from the video card, motherboard, hard disks, cooler, etc.).
2. It is necessary to close the two wires on the widest connector of those that are on the power supply. As a rule, it is green and the nearest black. You can do this with a regular clip or tweezers.
3. We supply voltage from the socket. And if the fans do not work, and everything is done correctly, then we can confidently say that the fault is in the power supply unit. If they are launched, then we can say that it is working.

Now you can connect the connectors back and solve the following problem.

How do I start the computer?

So, we found out that the problem is in the computer itself. What to do now? The motherboard has a lot of connectors, which connect the elements of the front panel of the computer case - buttons, LEDs, USB ports and other components. The connectors for the power button are usually located on the lower right side of the board. But the best way is to open the documentation for the used element and find out where it has contacts. If it does not exist, you need to find the inscriptions: "Power on / off" in English (Power Switch (PW Switch), Power ON, On-Off). After this, remove the connectors and gently close the PWR SW and Ground contacts. Than? Yes, even with a ballpoint pen.

Here's how to turn on the computer without the power button. And if after that everything works, then we know exactly what the problem is. It's in the on / off button itself. But what to do after clarifying this fact? Of course, repair or replace it. For a while, you can exit the situation with the reset button, by connecting it instead of the broken one. She, as a rule, signs Reset.

So in a simple way you can make the technique work. And if the power button is broken, you can recommend it as soon as possible to avoid this problem. But be careful - with inexperience or connivance the computer can be seriously damaged. Therefore, engage in a full-fledged repair only at your own peril and risk. Benefit can be very long to use the reset button.

Working with keyboard shortcuts

The keyboard is part of the computer, which is very much underestimated. Perhaps answering the question of how to turn on the computer without the power button, it was necessary to start with this method, both simple and easy.

For this we have to work with the basic input / output system. True, it's not so easy here. The matter is that for successful use of the given method the keyboard should be connected not to a USB-port, and to round-shaped PS / 2. If it is not so, then, alas, nothing will come out.

If the keyboard is the way we need it, you need to set the setting (namely, select the items that correspond to the buttons that can turn on the computer using the keyboard). This can be either a Space Bar (blank), or Power Key (the power button available on the "extended" keyboards) or Ctrl-Esc. After that, save the settings and turn off the computer to try out this innovation.

How to find the necessary property? Once the input to the basic input / output system was made, go to the Power Management Setup section and change the On by Keyboard. And here is an illustration to the question of whether it is possible to turn on the computer without the power button.

Features of technical design

As one person said, the cast button can be safer than a Soviet-made cast-iron frying pan. And well, it should be noted that there is a significant amount of truth in these words. Therefore, if the computer's power button does not work, then you can think about whether it's worth changing the unit of technology? After all, this is one of the most basic elements of a PC, so when it breaks down, we can say that the operation literally goes off scale. Or the technology of underground production from China was bought. To avoid this, you need to be careful when choosing a computer during its purchase.

Safety precautions

And now I want to go back a bit and talk about safety. It should be noted that most of the elements of the computer work under a small voltage, which is a unit or even a fraction of the volts. But not everything is so simple - otherwise it would not be connected to the 220 V network. Therefore, always, even with the smallest cosmetic changes, it is necessary to completely disconnect the equipment from any power supply. Of course, this is quite labor-intensive, but remember that all safety equipment is written by someone's blood.

Let's look at a small example of negligence. Here is a computer, in which the system unit is very difficult to disconnect from the power supply completely. It is put into sleep mode and the side panel is opened. And then an interrupt is triggered (for example, from a message that came through the network) and the technology is turned on. The current is unlikely to hit, but the fan on the motherboard can work well on the hands. Of course, he will not cut off his fingers, but he will be able to tangibly beat them with his blades.

Conclusion

Here we are and dismantled how to turn on the computer without the power button. But these were the most primitive ways to check status and activation. It should be noted that there is a sufficiently large number of different auxiliary equipment with which you can restore and run literally dead electronics. But it, as a rule, has experienced professionals who have been dealing with this matter for quite a long time.

Although, as previously mentioned, with such a breakdown it is still better to think about replacing the system unit. After all, in this case, you can remove all the "insides" from it and rearrange it into a new one. And this will save all the available developments, and the replacement will be forgotten in a few days.
