How to configure the BIOS so that the computer turns on automatically. Automatically turns on your computer when power appears - don’t let your computer sit idle

Friends, hello everyone! Today, purely by chance, I read one interesting computer setting coupled with an uninterruptible power supply. If you remember, not so long ago we configured in the case when the UPS switched to battery power.

And now we will do everything exactly the opposite. We'll set it up automatically turn on the computer when power is applied. Moreover, in this case it doesn’t really matter what operating system is installed on the machine (Windows 10 or 7), because nothing depends on it.

So, the first thing you should do is go to the BIOS system parameters. How to enter it in detail. Further, depending on the manufacturer, the actions may be different, but the essence remains the same, so don’t worry.

Specifically in my case, you need to open the section " Power Management Setup " and in the line " PWRON After PWR-Fail " specify the value shown in the screenshot below:

Where "Power Off (Off)" - will leave the computer in the off state when voltage appears in the mains. "Former-Sts (Last State)" - will return the machine to the state it was at the time the network was interrupted. "Power On (Always On)" - will always automatically start the computer when the power supply is restored.

That's all, we completely coped with the task. But let's dig a little deeper and further explore another interesting option called " Resume by Alarm " . To activate it, you must move the switch to " Enable " :

This setting allows you to start the PC on a specific schedule, the so-called alarm clock. The trick is that in the graph " Date " you need to specify the day of the month, and " Time " hours and minutes. The start will take place at the specified time. As you can see, everything is very simple.

Well, friends, automatic turning on of the computer when power is supplied has been studied in detail, and we can finish the article. Write your comments, ask questions, as they say, it will be more fun together. That's all for now and let's watch an interesting video.

The idea of setting up a computer so that it automatically turns on at a given time comes to mind for many people. Some want to use their PC as an alarm clock, others need to start downloading torrents at the most advantageous time according to the tariff plan, others want to schedule the installation of updates, virus scanning or other similar tasks. How these desires can be realized will be discussed further.

There are several ways you can configure your computer to turn on automatically. This can be done using the tools available in the computer hardware, methods provided in the operating system, or special programs from third-party manufacturers. Let's look at these methods in more detail.

Method 1: BIOS and UEFI

Probably everyone who is at least a little familiar with the principles of computer operation has heard about the existence of BIOS (Basic Input-Output System). It is responsible for testing and regularly turning on all PC hardware components, and then transfers control of them to the operating system. The BIOS contains many different settings, including the ability to turn on the computer in automatic mode. Let’s make a reservation right away that this function is not present in all BIOS, but only in more or less modern versions of it.

To schedule your PC to start automatically via BIOS, you need to do the following:

Currently, the BIOS interface is considered outdated. In modern computers it has been replaced by UEFI (Unified Extensible Firmware Interface). Its main purpose is the same as that of the BIOS, but the possibilities are much wider. It is much easier for the user to work with UEFI thanks to mouse support and Russian language in the interface.

Configuring your computer to turn on automatically using UEFI is as follows:

Setting automatic startup using BIOS or UEFI is the only way that allows you to perform this operation on a completely turned off computer. In all other cases, we are not talking about turning on, but about waking up the PC from hibernation or sleep mode.

It goes without saying that in order for auto-on to work, the computer's power cord must remain plugged into the outlet or UPS.

Method 2: Task Scheduler

You can also configure your computer to turn on automatically using Windows system tools. A task scheduler is used for this. Let's look at how this is done using Windows 7 as an example.

First, you need to allow the system to automatically turn on/off the computer. To do this, you need to open the section in the control panel "System and safety" and in the section "Power supply" follow the link "Setting sleep mode".

Then in the window that opens, follow the link "Change advanced power settings".

After that, find in the list of additional parameters "Dream" and there set the permission for wakeup timers to the state "Turn on".

Now you can configure a schedule for automatically turning on your computer. To do this you need to do the following:

Open your planner. The easiest way to do this is through the menu "Start", where there is a special field for searching for programs and files.

Start typing the word “scheduler” in this field so that a link to open the utility appears in the top line.

To open the scheduler, just left-click on it. It can also be launched via the menu “Start” - “Standard” - “Service”, or through the window “Run” (Win+R) by entering the taskschd.msc command there.
In the scheduler window, go to the section "Task Scheduler Library".
On the right side of the window, select "Create task".
Come up with a name and description for the new task, for example, “Turn on your computer automatically.” In the same window, you can configure the parameters with which the computer will wake up: the user under whom you will log in and the level of his rights. As a third step, be sure to specify the operating system to which the action of this task will be applied, in other words, the version of your Windows.
Go to the tab "Triggers" and click on the button "Create".
Set the frequency and time for the computer to automatically turn on, for example, every day at 7.30 am.
Go to the tab "Actions" and create a new action similar to the previous paragraph. Here you can configure what should happen when the task is completed. Let's make sure that some message is displayed on the screen.

If desired, you can configure another action, for example, playing an audio file, launching a torrent or another program.
Go to the tab "Conditions" and check the checkbox "Wake up the computer to perform a task". Add other marks if necessary.

This point is key when creating our task.
Complete the process by pressing the key "OK". If the general settings specified logging in as a specific user, the scheduler will ask you to specify his name and password.

This completes setting up the computer to automatically turn on using the scheduler. Evidence of the correctness of the actions taken will be the appearance of a new task in the scheduler task list.

The result of its execution will be to wake up the computer every day at 7.30 am and display the message “Good morning!” on the screen.

Method 3: Third Party Programs

You can also create a computer operating schedule using programs created by third-party developers. To some extent, they all duplicate the functions of the system task scheduler. Some have significantly reduced functionality in comparison with it, but compensate for this with ease of setup and a more convenient interface. However, there are not many software products that can wake a computer from sleep mode. Let's look at some of them in more detail.

A small free program with nothing superfluous. After installation, it minimizes to tray. By calling it from there, you can set up a schedule for turning on/off your computer.

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

Auto Power-on & Shut-down

Another program with which you can turn on your computer automatically. The program does not have a Russian-language interface by default, but you can find a localizer for it on the Internet. The program is paid, a 30-day trial version is offered for review.

WakeMeUp!

The interface of this program has functionality typical of all alarm clocks and reminders. The program is paid, the trial version is provided for 15 days. Its disadvantages include the long absence of updates. In Windows 7 it was possible to run it only in Windows 2000 compatibility mode with administrative rights.

This concludes our consideration of ways to automatically turn on a computer on a schedule. The information provided is sufficient to orient the reader to the possibilities for solving this problem. And which method to choose is up to him to decide.

Greetings, my dear readers.

I'll tell you about one interesting feature: auto-turn on the computer when power appears. Not many people know about it, this is understandable; in everyday life such a need rarely arises. For many of you, just one click on the button is enough to start the activation process. But what to do when the PC needs to be started without human intervention?

Network voltage is a great reason to work on your computer

Knowledgeable specialists will give you a lot of examples when such a need may arise:

The computer is a server;
It is necessary to provide round-the-clock access to the information stored;
Always active software is used (video surveillance systems, employee time records);
The PC operates in remote access mode;

Simply put, that’s why it’s a computer, to perform the tasks assigned to it automatically and without human intervention.

But, unfortunately, force majeure circumstances may interfere with the process in the form of an emergency shutdown of energy supply. The blackout period may last indefinitely, so the reserve as an uninterruptible power supply may not be enough.

Therefore, it would not be bad if the computer could turn on itself as soon as the power supply is supplied with operating voltage. This feature, implemented at the software level, is available on modern PCs, and you can activate it by changing the BIOS settings of the motherboard.

Since there are several types of BIOSes, I will describe algorithms for setting auto-on for the most common ones. To begin with, let me remind you how to get to the BIOS settings menu: when you turn on the computer, you should press the Del, F2 keys several times (or others that the system itself will tell you).

Good old ADWARD-Phoenix BIOS

Let's start with ADWARD, which also has a second name (modification) Phoenix, but both of them mean one product created after the merger of development companies.

Let's start by looking for the "Power Management Setup" section, which means power management. Next, we find the sub-item “PWRON After PWR-Fail” and in the column opposite it, change the setting by selecting “Power On” (or “Always On” depending on the BIOS version). This will be the function we need.

There is also the “Former-Sts” (Last State) option, in which the computer will be returned to the state before the emergency shutdown (its analogue is also present in other BIOSes).

The Real American System

Now let's move on to the American Megatrends Incorporated BIOS, which is similar in many ways to ADWARD, but has certain differences.

Moreover, versions of the AMI system itself may differ from each other. But since we know exactly what we need to find, it won’t be difficult to do. And we are looking for the “Power On” (or simply “On”) mode for the “Restore on AC Power Loss” setting.

And so, depending on the release date of the AMI BIOS, you can find it in different sections:

In the main menu “Power Management Setup” (for V4.3);
The desired menu is “ARM Configuration” and is located in the “Power” tab (for version No. 0401);
Select “ACPI Configuration” in the “Advanced” section (for P1.80 2011).

We work in comfortable UEFI

By the way, the last search route is also relevant for some UEFI BIOS, which is more modern, and for many more understandable (and in some versions it is even Russified). But we are now interested in the incomprehensible English version.

So, once you find yourself in such a BIOS, you need to activate the advanced mode: press the “Advanced Mode” key or just F7 (Here, just in case, look carefully to see if in “System language” there is an opportunity to change the language to your native one).

"Advanced" tab;
Section “APM” (penultimate point, don’t miss it);
Bah, all the familiar faces, our favorite (today) item « Restore on AC Power Loss"!
Of course, we set the “Power On” setting for it;

Just like that, in just a few clicks you can set your computer to turn on automatically when power appears. But in reality you will have to make more clicks. Do not forget to save the changes made to the system (sometimes you just need to press F10 in the BIOS).

If you come across BIOS versions that are not presented in this review, then I suggest studying several names that mean the function we are interested in:

Power State Resume Control
State After Power Failure
PWRON After PWR-Fail
AC Power Loss Restart
AC Back Function
System After AC Back
After AC Power Lost
After Power Failure
Power Failure
AC Loss Auto Restart
Power On After Power Fail
Restore on AC Power Loss
Power Again
After AC Power Loss

Knowing them, you can easily find the settings you need.

Something else

If you show additional interest in the settings, you may notice that by activating the “Restore on AC Power Loss” mode, you have the opportunity to set the days and times when your computer turns on. But this option is used quite rarely.

This concludes my post about auto-activation. I hope I helped those who were looking for an answer to this question.

Additionally, I hope that readers who are new to this feature will be able to put it to good use.

Good luck to everyone and see you again on the pages of my blog.

Recently they brought me a computer for diagnostics, which turns on itself when connected to a power outlet. There can be several reasons for this phenomenon - from a simple error in BIOS settings to a hardware malfunction, sometimes leading to expensive repairs. First of all, in this case, you need to find out - after which the computer began to turn on on its own, without the need to press the “Power” button. For example, in my case, after much questioning, I found out that the day before the client’s grandson was sitting at the PC and doing something “in the blue table.” That is, some BIOS parameters were changed. The problem was resolved in a few minutes and the client left satisfied.

Reason 1. Special function in BIOS

This is the main reason why the computer turns on by itself immediately after being plugged into the power supply. It is turned on and off on the motherboard, namely in the “Power Configuration” or “Power Management” section. There should be a setting called "After AC Power Lost".

Also, depending on the board manufacturer and BIOS version, the parameter may be called:

After AC Power Failure Restore on AC Power loss AC Power Loss Restart AC Loss Auto Restart AC PWR Loss Restart Power Again Power On After Power Fail Power Failure PWRON After PWR-Fail Power State Resume Control System After AC Back State After Power Failure

This parameter responds to the computer’s reaction when power is connected to it and has several meanings:

— Stay Off(or simply Off) — the computer will remain turned off and will not react in any way;

— Power On(or simply On) — the computer will automatically turn on when voltage appears in the electrical network;

— Last State(or Previous State) is the last state. If this option is selected, the behavior of the device when plugged into an outlet or power supply appears will depend on the state of the computer at the time of the power outage. That is, if it was turned off, nothing will change, but if it was turned on, it will turn on again.

So, if you don’t want the PC to turn on when plugged in, set the value to “Stay Off”.

Reason 2: Hardware failure

Unfortunately, in some cases, the computer’s autostart when power appears indicates that the computer’s components have failed.

The power supply is broken

Often, on cheap Chinese power supplies, there are so-called “breakdowns”, in which the PC turns on independently from an electrical impulse, without pressing the “Power” button. If you have such a power supply, then I strongly recommend replacing it before it’s too late, otherwise the next stage may be a breakdown of the motherboard, and this is already a significant expense.

Motherboard failure

This is the worst possible option and the most expensive. As a rule, spontaneous turning on of the computer (autostart) in this case means problems with the power supply. It can occur both on old motherboards due to swollen capacitors, and on new ones due to manufacturing defects.

P.S.: If surges and drops in the electrical network often occur in your home, then it is imperative to install a voltage stabilizer. Otherwise, even if you replace components due to a malfunction, after a short time the problem will repeat again and you will have to change the power supply or motherboard again.
