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 completely fail, and then the question becomes relevant: how to turn on the computer without the power button?
general information
It also happens that there is power on the network, the motherboard signals its work with its LED, but when you press the power button, nothing happens. 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 in a very complicated way?
It should be noted that the reasons for this behavior of technology can be extremely great. The article will consider several of the most popular options for failure and their elimination. Those that can be easily repeated at home will be given. If none of the following can help, then it would be better to contact the professionals so that they can fix the problem.
Quick but difficult check
Initially, it is necessary to check the operation of the power supply:
- To do this, you must first disconnect all the connectors (from the video card, motherboard, hard drives, cooler, etc.).
- You need to short 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 paper clip or tweezers.
- We supply voltage from the outlet. And if the fans did not work, and everything was done correctly, then we can confidently say that the fault is in the power supply. If they started, then we can say that it is working.
Now you can reconnect the connectors and solve the following problem.
How to start a computer?
So, we found out that the problem is in the computer itself. What to do now? The motherboard has many connectors, which connect the elements of the front panel of the computer case - buttons, LEDs, USB ports and other components. Connectors for the power button are usually located on the lower right side of the board. But it’s best to open the documentation for the element used and figure out where it has contacts there. If it is not there, then you need to find the inscriptions: “Turn On / Off” in English (Power Switch (PW Switch), Power ON, On-Off). After that, 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 for sure what the problem is. She is 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 get out of the situation with the help of the reset button, connecting it, instead of a broken one. She is usually signed by Reset.
In such a simple way, you can make the technique work. And if the power button is broken, you can recommend fixing it as soon as possible to avoid this problem. But be careful - with inexperience or connivance, the computer can be seriously damaged. Therefore, a full repair should be done only at your own peril and risk. Fortunately, you can use the reset button for a very long time.
Working with keyboard shortcuts
A keyboard is a part of a computer that is greatly underestimated. Perhaps, in answering the question of how to turn on the computer without the power button, you should start with this method, both simple and easy.
To do this, we have to work with the basic input / output system. True, not everything is so easy here. The fact is that for the successful use of this method, the keyboard must be connected not to the USB port, but to the round PS / 2. If this is not so, then, alas, nothing will work.
If the keyboard is the way we want, then you need to set the setting (namely, select the items that correspond to the buttons that can turn on the computer using the keyboard). It can be either Space Bar (space), or Power Key (power button available on the "advanced" keyboards) or Ctrl-Esc. After that, you should save the settings and turn off the computer in order to try out such an innovation.
How to find the necessary property? Once you have logged into the basic I / O system, go to the Power Management Setup section and change On by Keyboard. And here we have 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, only a Soviet-made cast-iron skillet can be more reliable than the power button. And well, it should be noted that a significant proportion of the truth in these words is. Therefore, if the computer’s power button does not work, then you can think about whether or not to change the unit of equipment? After all, this is one of the most basic elements of a PC, so when it fails, we can say that the operation literally goes off scale. Or, underground production machinery was purchased from China. To prevent this from happening, 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 a computer operate at a low voltage, which is units or even fractions of a volt. But not everything is so simple - otherwise it would not have been connected to a 220 V network. Therefore, always, even with the smallest cosmetic changes, it is necessary to completely disconnect the equipment from any voltage supply. Of course, this is quite laborious, but remember that all safety precautions are written by someone else’s blood.
Let's look at a small example of neglect. Here is a computer, in which the system unit is very difficult to disconnect from the power completely. It is put into sleep mode and the side panel opens. And then an interrupt is triggered (for example, from a message that came over the network) and the equipment turns on. It is unlikely to be shocked, but the fan on the motherboard can walk well. Of course, he won’t cut off his fingers, but he will be able to significantly beat them with his blades.
Conclusion
So we figured out how to turn on the computer without the power button. But these were the most primitive ways to check the status and activation. It should be noted that there is a fairly large number of various auxiliary equipment with which you can restore and start literally dead electronics. But it is usually owned by experienced professionals who have been in this business for quite some time.
Although, as previously mentioned, with such a breakdown, it is still better to think about replacing the system unit. Indeed, in this case, you can remove all the “insides” from it and rearrange it in a new one. And this will save all the available developments, and the replacement will be forgotten in a few days.
