The computer power button works, what should I do? Computer power button does not work

Lately, I have often encountered problems with the PC power button - Power buttons. Previously, I did not give it much importance and did not pay due attention. But in vain!

It happens that there is power in the network, the power supply, when the corresponding contacts of the connector are closed, starts with half a turn and works great. The motherboard signals with its LED the presence of standby voltage, but when pressed pwr buttons Nothing happens. The computer won't turn on!

Of course, there can be a great many reasons for this behavior, but it’s still worth paying attention to the PC power button!

What to do if the computer does not turn on?

1. You need to check the functionality of the power supply.

2. Start the PC, bypassing the power button, which is located in the PC case.

How to check a computer's power supply?

I answer. Express check of a computer power supply is carried out as follows:

1. Disconnect all power supply connectors from the computer (from the motherboard, from the video card, from all kinds of hard drives, coolers, and so on).

2. Now you need to short-circuit the two wires on the next connector. It is the widest of all that come out of the BP. You can short any black wire to a green wire. As a rule, I I close green and middle black(Earth). This can be done with a regular paper clip or tweezers.

If the power supply is supplied with 220 volts from the outlet, the wires are connected correctly, the power button on the power supply itself (there are such models) is turned on, and the fans of the power supply do not start, then we can state that the power supply is faulty. On the contrary, if, when you close the indicated contacts on the computer power supply connector, you see that the fans inside the unit are rotating, and not just twitching or silent, then the power supply is working.

At the same time we learned run a computer power supply without a computer!

Many experienced technicians may argue that such a test cannot accurately show the serviceability or malfunction of the power supply. And they will be partially right. But we do an express check, which in this case is quite sufficient. Moreover, not every user has a load stand or at least a multimeter to go deeper.

After checking the power supply, connect all connectors back. And we solve the next problem.

How to start a computer without a button?

Each motherboard manufacturer may have a different pin layout. Therefore, the best search option would be to open the documentation for your motherboard and find the location of these pins there. The documentation for the motherboard must come from the store; if you lost it or the seller did not give it to you (which happens very rarely), then the documentation for the motherboard can be downloaded online from the manufacturer’s official website if you have access to the Internet!

If there is neither one nor the other, then we look for the inscriptions on the connectors. As a rule, they are signed with letters Power Switch (PW Switch), Power ON, On-Off, not to be confused with PWRLED.

Here are typical connector pinouts from some manufacturers:

MSI motherboard

Asrock motherboard

Asus motherboard

Biostar motherboard

Epox motherboard

Gigabyte motherboard

Foxconn motherboard

Intel motherboard

We remove our connectors and carefully Briefly close the contact PWR SW and Ground. The computer should start. What to close? Ballpoint pen!

If the computer starts up, then the conclusion is obvious: the power button is faulty. What to do in this case? Try reconnecting the button to the motherboard connector; there may be a bad connection. If this does not help, remove the button, and then, depending on the circumstances, either repair the button or replace it.

To get out of this situation for a while, you can connect instead of the power button reset button(reboot) and use it to turn it on.

Thanks to these simple steps, you can start the computer without any problems, but this should not be neglected, and it is better to quickly repair the start button on the case 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 when 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.

Therefore, if you do not have sufficient qualifications and knowledge, I recommend that you contact a specialist.

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

general information

It also happens that there is power in the network, the motherboard signals about operation with its LED, but when you press the power button, nothing happens. The computer simply won't turn on! What to do in this case? How to turn on a computer without a power button, preferably in a not very difficult way?

It should be noted that there can be an extremely large number of reasons for this behavior of technology. Within the framework of the article, several of the most popular failure options and their elimination will be considered. Those that can easily be repeated at home will be given. If none of the things presented below can help, then it would be better to turn to professionals so that they can fix the problem.

Fast but complex check

First you need to check the functionality of the power supply:

To do this, you must first disconnect all connectors (from the video card, motherboard, hard drives, cooler, etc.).
You need to connect two wires to the widest connector on the power supply. As a rule, it is green and the nearest black. You can do this using a regular paper clip or tweezers.
We supply voltage from the outlet. And if the fans do not work, but everything was done correctly, then we can confidently say that the fault is in the power supply. If they start, then we can state that it is working.

Now you can connect the connectors back and solve the next 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 to which elements of the front panel of the computer case are connected - 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 it would be best to open the documentation for the element you are using and figure out where its contacts are. If it is not there, then you need to find the inscriptions: “On-Off” in English (Power Switch (PW Switch), Power ON, On-Off). After this, remove the connectors and carefully close the PWR SW and Ground contacts. How? Yes, even with a ballpoint pen.

Here's how to turn on your computer without a power button. And if everything works after that, then we know exactly what the problem is. It is in the on/off button itself. But what to do after finding out this fact? Of course, repair or replace it. You can temporarily get out of the situation using the reset button by connecting it instead of the broken one. It is usually signed Reset.

In this simple way you can make the equipment work. And if the power button is broken, we 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, you should carry out full repairs only at your own peril and risk. Fortunately, you can use the reset button for a very long time.

Working with keyboard shortcuts

The keyboard is a part of the computer that is very underestimated. Perhaps, answering the question of how to turn on a computer without a power button, you should have started with this method, which is both simple and easy.

To do this, we will have to work with the basic input/output system. True, not everything is so easy here. The fact is that to successfully use this method, the keyboard must be connected not to a USB port, but to a round PS/2. If this is not so, then, alas, nothing will work.

If the keyboard is what we need, then we need to set the setting (namely, select the items that correspond to the buttons that can turn on the computer using the keyboard). It could be either Space Bar (spacebar), or Power Key (the power button found on “advanced” keyboards) or Ctrl-Esc. After this, you should save the settings and turn off the computer to try this innovation.

How to find the required property? Once you have logged into the basic I/O system, you should 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 a power button.

Features of technical design

As one person said, the only thing more reliable than the power button is 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 there is a button, then you can think about whether it’s worth changing the piece of equipment? After all, this is one of the most basic elements of a PC, so when it fails, we can say that the exploitation is literally off scale. Or they bought clandestine equipment from China. To prevent this from happening, you need to be careful when choosing a computer when purchasing it.

Safety precautions

And now I would like to go back a little and talk about safety precautions. It should be noted that most computer elements operate under low voltage, which amounts to a few or even fractions of volts. But not everything is so simple - because otherwise it would not be 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 labor-intensive, but remember that all safety precautions are written in someone’s blood.

Let's look at a small example of neglect. Here is a computer whose system unit is very difficult to completely disconnect from the power supply. It is put into sleep mode and the side panel opens. And then an interruption is triggered (for example, from a message that came over the network) and the equipment turns on. It's unlikely to give you an electric shock, but the fan on the motherboard can give you a hard time. He, of course, won’t cut off your fingers, but he can beat them noticeably with his blades.

Conclusion

So we sorted it out, but these were the most primitive ways of checking 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, as a rule, it is available to experienced professionals who have been engaged in this business for quite a long time.

Although, as previously mentioned, in case of such a breakdown it is still better to think about replacing the system unit. Indeed, in this case, you can remove all the “internals” from it and rearrange it into a new one. And this will allow you to preserve all existing developments, and the replacement will be forgotten in a few days.

What to do if the computer's power button is broken? Surely many users will be at a loss as to how to turn on a computer without a power button. The motherboard is not only the basis for “hanging” computer components, but also a means of communication between modules. It also contains some very important parts within itself, such as the BIOS - a superstructure over the entire operating system and physical hardware, the battery that powers the CMOS memory in the computer, and much more. Not every user knows all the functions and capabilities of the modules and motherboard.

The Power button is usually made of plastic, and the main structure inside that supports it is also made of plastic. Often the stop in this design can break due to strong pressure, so we will not be able to turn on the computer in the usual way, with the power button. But there are several options to do this without a special button, although not as convenient.

To do this, you need to open the inspection cover of your system unit.

At first, until you decide to take the system unit for repair, you can use this method. You can also rearrange buttons or contacts if the shape and location of the case allows this.

Turn on the PC using a mouse or keyboard

Surely almost no one knows that a computer can be started directly from the keyboard (without the “Power” key on it) or a computer mouse. To do this, go to the BIOS by pressing and holding the required button, which depends on the BIOS version. This is usually the DEL key.

In the window that opens we need the “Power Management Setup” section.
Now find the “Power on by PS2” item, where you need to specify how to start the computer.
To select a specific key to turn on the computer, look for the “Any key” item.
Next, so that the parameters that you have set are saved, press F10 and confirm the exit and save the settings.
Now you can test the given key on your keyboard.

This method of turning on the computer without the Power button seems very convenient. To prevent the computer from accidentally turning on, for example, if there are small children in the house who climb everywhere, you can set several keys to turn on. In this case, instead of the “Any key” item, find “Hot key”, after which you will see “Ctrl-F1” at the bottom of the monitor. Click on it and you can set your own keys to turn on the computer.

BIOS item “Power on by mouse”

To turn on the computer by pressing one of the buttons on the mouse, go to “Power on by mouse” and click the right or left button to set it as the button to turn on the power.

Check the computer's power supply for serviceability

Sometimes the PC power button may not work due to a non-working power supply, which supplies all computer components with power.

This article describes how to turn on your computer. How to turn on your computer in the usual way and turn it on automatically using the basic “task scheduler” program.

Hello dear readers!
Let's look at the very first steps before starting to work on the computer, namely turning it on.

Connection in the usual way.

Before connecting your computer, you need to make sure that it, like any other electrical device, is connected to the power supply, preferably through a surge protector. This is a carrier with a power on/off button. It serves to protect against voltage surges. Also, several more peripheral devices are connected through it, such as: a modem, a printer, a system unit, etc. From all this, roughly speaking, in one word you get the computer itself.

By the way, an “uninterruptible power supply” or in other words an UPS/UPS uninterruptible power supply serves in case of a power outage with the battery, although only for a few minutes (about 10 minutes can be longer). In order to be able to save some started documents and also finish working with the computer, without any consequences.
I highly recommend using an uninterruptible power supply, a very necessary and useful thing for you and your computer.

And so after you have made sure that everything is connected, there is electricity in the network. We start the uninterruptible power supply by pressing and holding the power button for several seconds (2-3 seconds). The “UPB” should beep and the lights on it should light up.
If the beeping continues, it means there is an electrical problem or look at the power supply, the filter may be, the button is not turned on or the fuse is blown, or even more serious problems. I hope that this does not happen and that the switching on will occur without problems.

Then we start the monitor by pressing the power button, it can be either in front or on the side of the screen. Then press the power button on the system unit. After a short loading process appears
Now let's move on to the next activation method.

Enabling via the task scheduler.

This is a basic program, called a “task scheduler”, with its help you can schedule programs to automatically launch at the right time, schedule the sending of email, etc. We will use the scheduler as an alarm clock or simply turn on and off the computer at a given time.
Let's look at the setup process through the task scheduler.

First, we check whether “sleep mode” is enabled. To do this, go to “”, select the “control panel” tab, then “hardware and sound” in the next “power” window, click on the “sleep mode settings” tab.

In this window, click on the plus signs “Sleep” and then “Allow wake-up timers”, after which two items will appear.
— “On battery”
— “Online”
If they are turned off, then turn them on, click “OK” and move on to the next step.

We go to the start menu in the search bar and write “task scheduler” by double-clicking with the left mouse button to enter the program. In the window that opens, click the “create task” tab.

In the next window, in the “name” line, write for example: turn on the computer. Check the “Run with highest rights” checkbox. Then go to the “Triggers” tab and click “Create”.

Here is a list of launch options: date and time, enter your values and click “OK”.

Then click on the tabs in order:
- "Actions"
- "Create"
- "Review"
Here you will need to select the local drive on which the folder with MP3 files is located, find and open it. Click on the song that will sound when turned on, click “Open” and “OK”.

In the last window, click the conditions tab and check the box “Wake up the computer to complete the task” and “OK”.

That's all, the alarm clock will go off at the time you specified and the computer will turn on, if, of course, you strictly followed the above instructions. However, this method will only work if the computer is in modes; when the computer is completely turned off, the “scheduler” unfortunately does not work!

There is also a way to turn it on via the “BIOS” (basic input system), but at first it’s better not to go there, so we won’t consider this method, at least in the initial article. I hope this article “” will be useful to someone.
I’ll leave it at that, thank you for your attention until we meet again.

The very first fear that novice users have is the fear of turning on the computer. Elderly people are especially susceptible to this fear. Today we will “fight” this fear. Usually there are no problems the first time you turn it on. But some people not only don’t know how to turn off the computer, but also don’t want to learn how to do it. But in vain! As practice shows, 80% of computer malfunctions are caused by users, and of these 70%, 30% are due to improper shutdown of the computer.

If you are reading these lines, it means that somehow you have already turned on your computer, or someone has turned it on for you.

Remember once and for all! You can't mess anything up. If something goes wrong when you turn on the computer, it is most likely the consequences of a virus, or an incorrect shutdown of the computer.

To avoid such troubles, you must immediately learn how to properly turn on and off your computer. The same applies to laptops and tablets.

Connecting your computer to an electrical outlet

The most correct thing is to connect the computer through a “pilot” type surge protector.

You need to plug one of these devices into an electrical outlet first. An uninterruptible power supply is quite expensive equipment, so it is more necessary if your lights are often turned off, or if your apartment constantly experiences voltage surges in the electrical network.

In other cases, you can get by with a less expensive device for protecting against sudden power surges - this is the so-called surge protector. It has a small black button on one edge. In the event of a sudden voltage surge, this button will automatically turn off the flow of excess current to the devices connected through the “pilot”.

Do not connect your computer directly to a power outlet, otherwise you risk not only losing all your data, but also being left without a computer. The same applies to the monitor. All of these devices can be connected to the outlet through one device (either a “pilot” or an uninterruptible power supply).

Never use cheap Chinese extension cords. Buy equipment only from specialized computer stores. Otherwise, you will burn not only your computer, but the entire apartment. This is not a joke! Don't tempt fate.

How to turn on your computer correctly

In order to turn on the computer, you must:

Make sure that it is connected to a 220 V electrical network;
Make sure that this network has voltage;
Make sure that all computer cords are tightly seated in their connectors;
Press the button to turn on the surge protector, uninterruptible power supply (if available);
Press the power button on the front panel of the system unit;
Press the power button on the monitor;

How to turn on a laptop or netbook correctly

Check the presence of power in the 220V electrical network (if you turn on the laptop from an outlet);
Connect the cable from the power supply first to the laptop connector, and then connect the plug to the electrical network;
Open the laptop lid;
Press the power button on the laptop;
Wait for the operating system to load.

Usually there are no problems turning on the computer. The main thing is not to panic and not to press all the keys on the keyboard during loading.

How to properly turn off a computer, laptop or netbook

After you have worked or played on your computer, you need to turn it off properly. Exactly CORRECT, because. this will determine whether your computer turns on next time or not.

It often happens that after an incorrect shutdown of a computer (laptop or netbook), the boot file fails and the computer cannot start. Most often, this situation can be corrected, but this must be done by a specialist. Or it could be worse. Then you will have to reinstall the entire operating system.

To avoid problems, the computer must be turned off correctly. Left click on the button Start(in the lower left corner).

You can turn off your computer, laptop, or netbook only through the button Start. There is nothing complicated about it.

Remember how to properly turn on and off your computer, and you will never have unnecessary problems.
