What to do if the computer starts independently

Sometimes such a problem appears when the computer itself turns on. Indeed, it looks unusual, because the computer no one touchs how it can turn on? Consider possible options.

If with contacts button on the problem, then it can work random. To eliminate this option, you can open the system unit cover and disable the button from the motherboard. To do this, you need to explore the place where the wires from the front panel are found on the motherboard, find the connector containing the word “POWER” and turn it off.

Also, on some motherboards there is a jumper that controls the power on when the power is applied to it. For example, if the jumper is worth it, then when powering 220V, the computer spontaneously turns on. Thus, when the electricity is disappeared and the appearance, this will take place regularly. You can find such a jumper in the manual instructions. It is usually called “Power-On After Fail”. On other boards, behavior when the nutrition appears from BIOS, about it below.

Automatic switching on the computer after the appearance of electricity in the network

May certainly issue from the field of fantasy, but still. There is a computer, it is connected to the network via UPS. UPS is configured so that after 15 minutes of work without light, turn off the computer. The task is reduced to how to make a reverse operation? After the appearance of light, the computer automatically turned on. Interested in any options.

If the UPS disables the computers (“smart”, connected via USB / COM, it is completed), then it should be able to enable it and enable it (in the settings of the UPP and in the BIOS “Wake Up ON USB / COM”). If it disables it just a hard food, and then the power is engaged, then setting up in the type “ON POWER FAIL”. “POWER ON”. If the UPS simply cuts the power and waits for the button while you click on it to file it again, then you need to click the button.

Upseck itself turns off after 15 minutes without light? Whether it turns on when light appears? If turned on, then as already suggested, look in the side of the BIOS. If not. you need to learn the UPS itself to start.

I have to turn on the computer from USB devices (configured in the bios). Sometimes, when voltage transmits, apparently UPS reports this PC and that it turns on. The funny thing is when the light is turned off, and the computer is turned off at that moment, UPS reports PC, and the computer turns on.

Here the person has a completely reverse problem. As far as I understood, he has a computer turns on when electricity appears because of this setting in BIOS.

It depends on something from the power supply. There are blocks (I met only from old models) which when applying power turns on themselves.

In theory, you can make a system on control signals that will operate in two positions and is connected to the network and the power button PC. Which will check the presence of voltage in the network to the UPS, if not, then the system is in the first state, nothing happens, but if the voltage appears, the system goes into the second position, sending a signal to the PC on button, it turns on. That is, the triggering takes place one time in case there are no dips, it does not work if it appears, the system sends a signal to the PC button. But if it was a short-term shutdown, and the PC worked at this time from the UPS, then the system will turn off the PC 🙂 It is necessary to introduce an even check after the UPS, so that this does not happen. It is more difficult. Something I signed.

About BIOS You have already written “On Power Fail”. “Power ON”. It’s all about UPS. There are 2 types: the first. when you disconnect the email and the discharge of the batteries, it is cut down and it is necessary to turn it on manually to power the power to the computer. The second is newer and expensive UPS. They have such an option “Cold Start Function”. it just allows the uninterruptible to turn on the email to the network itself. t.E. You need in the BIOS. “ON POWER FAIL”. “POWER ON” in UPS. “COLD START FUNCTION”

Cold Start Here, it seems, nothing. Cold Start Mode Allows you to enable UPS in battery mode in the absence of voltage in the electrical network. This mode allows you to “powered” any electrical device already in the absence of voltage in the electrical network. For example, in this way, you can “raise” a remote network switch and ensure the operation of the local network.

I have a UPS PowerCom “King 625”, is associated with a computer via RS232 = USB. On the PC program Upsmon, where the computer is turned off 5 minutes after the power drop in the network. UPS itself is also turned off after 2 minutes after the completion of the computer. In PC (ASUS P5K SE EPU) in the BIOS set the value “Last State” and “Wake up by. “Everyone is crushed (I don’t remember exactly what parameter, now I can not look exactly). After the power loss, the computer completes the work, the UPS also ships. With the appearance of power turns on everything automatically.

In BIOS, there is such a function, but after a well-off shutdown of the computer, it will not turn on. The thought was about the closure of the button, but then the scheme of a primitive device, which will check whether 220V be checked and as a result, wash the button.

I have something doubts take what happens. Need a closing relay that will make a closure for a second only once when the electric current occurs in the chain, otherwise after three to five seconds, the mother turns off the computer.

But, the good news is that the scheme is quite simple will be. You can also solder, everything is simple, something about that

You need 2 relays: 1) 1st closes the power button and the second relay 2) 2nd relay opens the first 3). 4) Profit!

Nutritional problems 220V

Yes, trite, but some about it just forget. Therefore, first make sure that there is a power outlet 220V. To do this, it is enough to connect to it instead of a computer any other device, such as a mobile phone or lamp. Note How many other devices are connected via extension cords or splitters to one outlet. It is possible that the permissible load is exceeded and the protection is triggered.

Try to turn off all the devices, leaving only the computer, and see whether it works now or not. With highly lowered or overestimated voltage on the network, the computer may not be turned on or in general. Check the voltage can be a special tester or eye on the incandescent bulb (not energy-saving). With a reduced voltage, the bulb glows dimly than usual, and with an increased vice versa. brighter, or ignites, but quickly burns but it is in extreme case, it’s better of course the tester.

It happens that everything is in order with the outlet, but electricity to the computer does not reach due to poor power cable contact. You need to try to pull the power cable from the system unit and insert tightly back.

If it is clearly seen that the cable is crazy and very Chinese, in any case it is better to replace it with something for something (you can check the cable from the monitor). And do not forget to turn on the button on the power supply, which is located next to the power socket (there is not all), it should also be in the “On” state

Third-party programs

Create computer work schedule You can also with the help of third-party software developers. To some extent, they all duplicate the functions of the system scheduler of tasks. Some have a significantly trimmed functionality compared to it, but compensate for it ease in setting up and more convenient intees. However, software products capable of displaying a computer from sleep mode exists not so much. Consider some of them Read more.

A small free program in which there is nothing superfluous. After installation, folded in the tray. Calling it from there, you can configure the computer on / off schedule.

    In the program window, you need to go to the appropriate section and set the required parameters.

Thus, the enable / off of the computer will be scheduled regardless of the date.

Another program with which you can turn on the computer on the machine. Russian-language inteeis by default in the program is missing, but you can find a Russifier for it. The program is paid, a trial 30-day version is proposed.

    To work with it in the main window you need to go to the scheduler tab (Scheduled Tasks) and create a new task.

The inteeis of this program has a functionality typical of all alarm clocks and reminders. The program is paid, the trial version is available for 15 days. The shortcomings should be attributed to the long lack of updates. In Windows 7, it was managed only in compatibility mode with Windows 2000 with administrative rights.

    To configure the automatic awakening of the computer, in its main window it is necessary to create a new task.

This can be completed consideration of how to automatically turn on the computer on a schedule. The information provided is enough to orient the reader in the possibilities of solving this problem. And which one of the ways to choose. to solve himself.

We are glad that you could help you solve the problem.

Describe that you did not work. Our specialists will try to answer as quickly as possible.

Why do you want the computer to turn on or turned off automatically?

As we have already mentioned, the automatic switching on or off PC may not be required on many PC, because in fact any computer with a solid-state drive takes a short time to start; However, there are some situations in which it can be quite useful, for example, if you go on vacation and take a low-cost laptop to work with the intention to remotely connect to your home or office PC, much more powerful and where you already have the necessary programs and documents.

So you can force the PC to which you are going to connect remotely, turn on every day at 9 am so that you can connect to it with comfort, and then turn off at the end of the day (or not, the connection setting is thinner, because if you Connected to a computer, you can always turn it off by manually in the usual way when it is no longer needed).

In the same way, and moreover, now where electricity tariffs are changing according to the schedule, you may be interested in the computer automatically turned on at a time when the target is the cheapest and when it starts the mining cryptocurrency (using simple Windows-based ) automatically and then turn off when the most expensive electricity tariff approaches.

How to configure it all turn on / off

This wonderful setting (I am about turning on the computer by pressing the buttons on the keyboard) dwells in the BIOS section (I remind you that it is necessary to press the DEL button on the earliest stage of the computer, T.E. Almost immediately after switching on) Power. APM Configuration:

As you probably already understood, there is a small snag, namely, it is important that your keyboard (or one of them) is connected to the PS / 2 connector (round such), and not USB otherwise nothing will happen.

If the keyboard is this, then we boldly set it to the setting in the position we need (T.E. Select between items that indicate the buttons on which you can turn on the computer from the keyboard. space bar (space), Power Key (power button, is on “advanced” keyboards) or Ctrl-Esc) and, without forgetting to save the settings, turn off the computer in order Touch innovations.

You need to go to the Power Management SETUP section and setting the Power On by Keyboard setting there:

.in one of the available and necessary provisions.

Voila. It remains only a clever movement of the hand to turn on the beloved iron friend without leaning under the table and not clapping, if it is of course you have, the door of the case.

Temporary measure: How to “not give” a computer to engage in your absence

Spontaneous PC inclusion is not only uncomfortable, but also dangerous (especially if it will work when there will be no one at home. ).

over, if the PC “behaves like this”. it means (as already said above) may be serious. Malfunction (and the same power supplies in terms of faults often and wake up and flammified!).

So that nothing bad happens. disable the power of the problematic computer from the 220V network, when you leave it unattended!

Best Solution Option. Remove the plug from the outlet (or off. Network filter by pressing the switch button).

If your power supply is configured (and was rechecked). you can turn off the PC and use the button on its body (usually located on the back side of the system unit, next to the power cable).

Configure BIOS or UEFI

BIOS is a software shell built into the default computer. It allows you to install the operating system and supports the basic functioning of the main components of the PC. Among other things, this shell contains a variety of settings required for the correct functioning of the computer. You can change them, including configuring the automatic switching on the machine.

However, in working with the BIOS, you need to be careful, since any incorrect effect can lead to the failure of both the entire computer and the operating system. If you understand the PC very badly, then it is better for you to consider other methods that are written below.

The BIOS setting to automatically turn on the computer is as follows:

  • First you need to enter the BIOS inteeis. Run the computer and, without waiting for the full boot of the operating system, press the key or combination the keys to enter the BIOS. This key or their combination depend on the manufacturer of your motherboard. Most often to enter the login in the BIOS, the Del or F2 key is used.
  • Find in the menu “Power Managevent Setup”. It can be located in the “Advanced” submenu or “ACPI Configuration”. In this case, first go to it. If this section is not at all, it means that the BIOS does not support the automatic power on and off setting.

It should be understood that there are different versions of the BIOS and the presented instruction H is universal. In your version, the presented items may not coincide.

Also on some computer installed UEFI, and not BIOS. There is a control using a mouse, and not just keys, plus, in some versions you can choose the language of the intees. Configuring the automatic power on the computer using UEFI is as follows:

  • Make an entrance to UEFI-INTEYS. It is made by analogy with BIOS from the first instruction.
  • Being in the main window of your UEFI-shell, move to the “Optional” section by clicking on a special button or using the hot key F7. Also, the desired button can be called “Advanced” if you enabled the English version of UEFI.
  • “RTC Alarm Date (Days)” Here we register the day of the month in which automatic inclusion is planned. Setting the value 0 You put automatic switching on every day.
  • “Hour” Inclusion hours: from 0 to 23.
  • “MINUTE” Minutes of inclusion: from 0 to 59.
  • “Second” seconds. Configured by analogy with moments, but they can not be touched.

Unfortunately, an option with BIOS or UEFI is the only possible if you need to turn on the computer that is completely turned off. The remaining methods imply automatic output of the computer from the hibernation mode or sleep mode.

Try to turn off all peripheral equipment

In general, only: Motherboard, RAM, Processor, Video Card, Power Supply. Try to turn off your motherboard everything that is possible: printers, scanners, mice, tuners, audio card and t.D., Leaving only the foundation.

If the computer turns on, try after connecting one board, each time rechecking (whether PC will turn on after connecting the next device). Such an exception can be found.

From experience I can advise first of all to pay attention to various media devices: tuners, audio cards, USB hubs, modems.
