Turning on the computer when power is applied. Scheduled automatic turning on of the computer - activate. Reasons why the computer turns on by itself when power is applied

The idea of ​​setting up a computer so that it automatically turns on at a given time comes to mind for many people. Some people want to use their PC as an alarm clock, others need to start downloading torrents at the most advantageous time according to tariff plan time, others want to schedule installation of updates, virus scans, 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 provided 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. BIOS contains many different settings, among which is the ability to turn on the computer in automatic mode. Let's agree right away that this function It is not present in all BIOS, but only in more or less modern versions.

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Currently, the BIOS interface is considered outdated.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 was 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 to automatic switching on may have tripped, 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 system settings. Windows 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 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:

1. 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.
2. In the scheduler window, go to the section "Task Scheduler Library".
   
   
3. On the right side of the window, select "Create task".
   
   
4. 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 indicate operating system, to which the action of this task will be applied, in other words, the version of your Windows.
   
   
5. Go to the tab "Triggers" and click on the button "Create".
   
   
6. Set the frequency and time for the computer to automatically turn on, for example, every day at 7.30 am.
   
   
7. 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.
8. 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.
9. 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.

Small free program, in which there is 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, trial version 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.

Some users contact us with the problem that the computer turns on itself when power is applied. This is quite rare, but this problem cannot be ignored. Automatically turning on the computer when power is supplied can lead to catastrophic consequences for the computer, for example, the motherboard may burn out. There is also a possibility of losing valuable data on your hard drive. If you have this problem, it is recommended to create backups data until you solve it.

How does this problem manifest itself? When you plug in your computer, the power supply and motherboard automatically turn on, but the monitor doesn't light up until you press the power button on the case. Also during shutdown, you may see that the cooler and all computer hardware are turned off, but the indicator on the motherboard is still on.

This problem must be resolved as soon as possible before serious damage is caused to the computer hardware.

Reasons why the computer turns on by itself when power is applied

1. Faulty power supply. A faulty power supply could be the culprit behind this problem. You can test the performance of your power supply using a paper clip.
2. Problem with settingsBIOS. Check BIOS settings on the motherboard and make sure the correct computer startup options are set. Next we will look at how to do this.
3. Faulty power button on the computer case. Shorting the wires to the power button in the computer case can cause the computer to turn on when power is applied.

Note: If you hear beeping sounds when you turn on your computer, there may be a problem with RAM or hard drive.

Solutions

1. Check the power supply using a paper clip. The video below shows how to do it correctly.

2. Go to BIOS mode on your computer. Next, open the tab “ Power", and in the parameter " AfterPowerFailure» select « StayOff" After that, go to the “ Exit", and select " ExitsavingChanges».

3. Check all the wires near the power button inside the computer case to make sure they are not shorted.

If the power supply, BIOS settings and power button on the computer case are fine, then most likely the problem is with the motherboard. In this case, you must contact the service center.

We hope we helped you solve the problem when the computer turns on by itself when power is applied. You should not put off solving this problem until later, otherwise more serious problems may arise, for example, the motherboard will burn out.

Today there is a sufficient amount of software with which we can control the automatic turning on of the computer according to a schedule. But I want to note that automatically turning on the PC using programs is only possible when it is in “sleep” mode.

That is, a computer that is in “sleep mode,” as it would be easier to say, is already turned on. It just “wakes up” and doesn’t turn on.

It turns out (I was ashamed not to know this :)), you can configure the computer to automatically turn on according to a schedule and even when it is COMPLETELY OFF! Modern BIOSes that come with PC motherboards have settings to automatically turn on a switched off computer according to a schedule.

At the beginning of my acquaintance with computers (since 1995), such a setting in the BIOS could only be dreamed of. For what purposes you can use turning on the computer automatically is up to you to decide.

For example, from the most banal - using a PC as an alarm clock, turning it on to distribute or download torrents while you are away, servicing your computer, or even when you are at work or on a business trip, etc.

I note that the fourth computer I tested, purchased 6 years ago, did not yet have this capability. Let's now move directly to the BIOS settings.

How to enter the BIOS depends on your configuration motherboard, mainly by pressing the Delete or F2 key on the keyboard on initial stage computer boot. You can see a hint on the required keys immediately when you turn on the PC.

AUTOMATICALLY TURNING ON THE COMPUTER

BIOS American Megatrends Inc. P1.80, 05/20/2011. Go to the “Advanced” section and select “ACPI Configuration”.

Turn on the “Restore on AC/Power Loss” setting to the “Power On” position.

We activate (“Enabled”) the auto-on setting “RTC Alarm Power On”.

We select to turn on the computer every day (“Every Day”) or on a certain date within the current month in the “RTC Alarm Date Every Day” settings. We configure the PC turn-on time: “hour/minute/second” in “RTC Alarm Time”.

After completing the settings, press the F10 key or the “Save Changes and Exit” and “OK” item to save the settings and restart the PC.

BIOS American Megatrends Inc. V4.3, 10/21/2009. We need the “Power Management Setup” section, go to it.

Turn on the “Restore On AC Power Loss” setting to the “On” position.

Activate “Resume By RTC Alarm”.

We set the activation for every day or on a certain date of the month in the “Data” setting and hours/minutes/seconds in “HH:MM:SS”.

Save the settings and exit the BIOS using F10.

BIOS American Megatrends Inc. 0401, 05/05/2010. In the “Power” section, go to “ARM Configuration”.

We activate “Restore on AC Power Loss” to the “Power On” position.

Activate “Power On By RTC Alarm”.

Settings for daily activation at certain hours/minutes/seconds become available.

Or a specific date, hours/minutes/seconds.

If you no longer need to automatically turn on your computer on a schedule, simply disable (“Disabled”) the “Power On By RTC Alarm” setting.

Unfortunately, these are all the BIOS versions on which I was able to test the function of automatically turning on the computer. If you have a different basic input/output system (BIOS), then you will already know where to dig. And finally, I suggest you watch a short video
