A fairly common "nuisance" in the computer is regular failure time. If you notice this error and you are not indifferent to it, do not rush to send your computer to service center... You can make a "diagnosis" and cure it yourself.

What are the reasons for losing time on the computer?

There may be several reasons. First, pay attention to whether the date set on the computer is lost along with the time? And also on when these parameters fail - during operation, after shutdown, or when the Internet is connected?

Depending on the manifestations of the error, the following solutions are used to eliminate it:

1. The date is correct, the time settings get confused, presumably when connected to the Internet. The solution to this problem is to cancel the synchronization of the computer time with the time server on the Internet. This can be done by changing the settings for the date and time of your computer in a convenient way for you - either through the control panel, or by clicking on the time icon in the taskbar - tray.

2. The date is correct, the time gets lost when the computer is turned on for a certain number of hours. Cause - the time zone set on the computer does not match the actual location. In the same settings for the date and time, the time zone selection should be adjusted.

3. Time and date are lost at the same time after turning off the computer. To understand this situation, let's touch on the theory. The fact is that to maintain constant settings during computer operation, in the system, during a power outage, there is a subsystem called CMOS - a memory chip that stores all the data for startup. The CMOS is powered by a CR2032 battery. Its average service life is 3 - 4 years. Further, like any other battery, it becomes unusable, and the CMOS system ceases to maintain constant startup parameters.

There is only one way out - the battery needs to be replaced.

On the motherboard, it is located in an accessible place and can be changed without much difficulty. Disconnect the computer from the network, and remove, depending on the type system unit, or its right side panel, or the entire case cover. A round white "pill" the size of a two-ruble coin will be clearly visible on the board. This is the battery.

Having previously bought the appropriate type of battery (CR2032) in a computer store, replace it.

After that, when you start your computer, do not forget to go to BIOS and set the date and time parameters you need to work.

Like these ones simple actions will help you determine the cause and resolve the timing outage problem on your computer.

Comments

The main reasons why time gets lost are battery failure, updating when choosing the wrong time zone, and third party programschanging the date. Each of these causes of a malfunctioning system clock is easily corrected at home.

Depleted CMOS battery

The clock on the computer does not stop timing even when the device is disconnected from the electrical network... The CMOS is powered by a flat battery on the motherboard, typically 3V. It is designed to operate continuously for several years, but the cell is not charged when the computer is turned on. Therefore, if the power source is low, for normal work hours require replacement.

Important! You can buy a new battery not only in a computer store, but also in the corresponding departments of other stores.

To replace the CMOS battery, follow these steps:

1. Turn off your computer.
2. Disconnect the power supply.
3. Remove the side cover of the system unit.
4. Locate the battery (usually located in the lower right corner of the motherboard).
5. Bend the metal holder with a screwdriver or other object.
6. Insert the new battery with the correct polarity (plus is at the top).
7. Close the lid of the system unit and turn on the computer.
8. Rebuild if necessary standard settings BIOS.
9. Set the correct time parameters.

Note! For a new battery to work, it must have the same markings as the old one. It is often CR2032, but CR2016 and CR2025 can also be used.

Time is translated by viruses or program activators

Use of unlicensed software with activators can lead to the fact that the time on the computer gets lost. Some programs have free versions, limited in time. To renew the license, activators use a simple method of setting the clock back. If the time starts to get lost after installing such software, uninstall it.

Also, the clock can be translated by malware. If you do not have an antivirus installed on your computer, download any free tool verification that does not require installation. For example, "Zillya", "Dr.Web CureIt" or "ESET Online Scanner". In the latter windows versions there is also a built-in antivirus. Open Windows Defender by clicking on the tray icon. Select the scan type in the right column and click Check Now. Available verification options:

• Fast
• Full
• Special

When you scan your computer for the first time, we recommend that you select full check... The mode selected in the previous step determines the duration of the process. Also, the speed of the device and the amount of space on hard disk... You can stop scanning for viruses by clicking the "Cancel scan" button.

Important! Before starting the scan, do not forget to download the latest anti-virus databases on the "Update" tab.

Wrong time zone

In the case when the time zone on the computer is set incorrectly, when synchronizing the clock, the time is lost. Even if the correct time is set after that, the next update via the Internet will return the values \u200b\u200bfor a different time zone. To change these settings, click on the current time in the lower right corner of the screen. Follow the link on the calendar pop-up window.

Today we will deal with the problem: why the date and time settings can get lost when the operating system boots. Do not worry, nothing terrible happened to your computer and the issue can be resolved on your own.

Time Zones

The first reason is the wrong time zone. Therefore, when you load the operating system, the time is synchronized with the server and, accordingly, is set incorrectly.

To view which time zone you have selected, you must click right click mouse on the clock located in the tray, and from context menu select item Date and Time Setting.

In the next window, look at the set time zone. If it is selected incorrectly, click on the button "Change time zone ..." and set the desired value. Then click on the "Apply" and "OK" button.

Transition to another time

The second reason is automatic daylight saving time. As you know, since 2014 in Russia this transition has been canceled. That is why the clock on your computer may either lag or rush by 1 hour.

To solve this problem, you just need to perform updates for the installed operating system. If, by for known reasons, you cannot do this, then we will consider other methods.

To do this, again right-click on the clock in the tray and select from the context menu Date and Time Setting... In the next window, go to the tab "Time on the Internet"... Here we click on the button "Change parameters"... Now you need to uncheck the box "Synchronize with an Internet time server" and click "OK". Then we press "Apply" and "OK". Then just set the correct time.

You can also try changing the time zone. For example, you had UTC + 03.00 set, change it to UTC + 02.00.

The battery on the motherboard has run out

The third reasonwhy the time and date on the computer is lost, there may be a dead battery on the motherboard. And they go astray every time you turn off the power of the system unit.

The thing is that when the computer is disconnected from the mains power, the system time and bIOS settings do not go astray only thanks to the power received from the battery. Therefore, when it sits down, when the operating system boots, a window may appear where you are, and then the time and date are also incorrect.

In this case, you need to disconnect the system unit from the network, unfold it with the back cover towards you, unscrew the screws with which the side covers are attached. Then remove the side cover and find a small battery on the motherboard. It has the form of a pill, provides a voltage of 3 volts and is usually called CR2016, CR2025, CR2032. Gently take it out, it is attached there with a latch, and buy the same one in the store - they are not expensive. Then install the battery and put the parts of the system unit back.

Now we turn on the computer and immediately. This can be done by pressing F2 or Del when loading the operating system. We set the correct date and time there. Then we exit the BIOS and wait for the system to boot up. Then just set the correct date and time on your computer.

Viruses

Fourth reason can be called computer viruses... Moreover, they are being introduced into system files and because of this, the date and time settings may get lost.

Check your computer with an antivirus program. Moreover, it is better to do this not only with the one installed on the computer, but also with a couple of others. If something goes wrong, remove the found viruses. If you are still in doubt, check non-system drives for viruses, format system disk and on the computer. You can read more about that in a separate article.

I hope that one of the above methods will help you. And when loading the operating system, you will no longer be disturbed wrong settings date and time on your computer.

Once again, I was faced with the fact that my computer time was lost. I set the time, use the computer, and after shutting down, the time gets lost again. What is the reason for this ailment?

Everything is very simple. The fact is that a battery is installed on the motherboards, which is responsible for the operability of the CMOS - memory that controls the BIOS settings, as well as the time settings. When this battery stops working normally, time failure occurs.

There have been cases when, due to a dead battery, Windows stopped boot normally. In general, if the battery runs out, itneed to change. But how to determine that the problem is in the battery.

Why the time on the computer gets lost

If, when you turn on your computer, your Windows time gets lost, then you need to make sure that the problem is not related to the operating system... This can be done as follows.

• Reboot your computer
• When you turn on the computer, enter the BIOS. It should be noted that at the moment you can enter BIOS different ways ... It all depends on your motherboard. My motherboard is outdated, so I enter BIOS using the "Delete" button. When the computer turns on, I press the “Delete” button and hold it until the BIOS appears.
• When the BIOS interface opens, look at the time. If the time does not correspond to the real one, then most likely you need to change the battery.

If the time is indicated in the BIOS correctly, then you need to deal with the operating system itself, perhaps the problem is in it.If you determine that the problem is with the battery, then how do you change it?

Battery replacement

Attention! Replacing the battery involves disassembling the computer. When disassembling the computer, there is a danger of being affected electric current... Be careful! If you are not sure of your knowledge, it is better to consult a specialist.

At the moment, motherboards use standard batteries marked "CR 2032".

That's all, the battery has been changed. Now you can collect the system unit.After assembling and connecting all the wires, you need to set the date and time in the BIOS.

Setting the time in BIOS

Turn on the computer and enter the BIOS. As I described above, this is done using the "Delete" button. At least that's how it is for me, perhaps you do it differently.If you do not know how to enter BIOS, search the net. Type in a search phrase like: "how to enter BIOS on ... (model of your motherboard)".

You have entered the BIOS, find the date and time in the settings and configure them. Below is a photo of how this setting looks for me.

Menu item where time is set.

Time setting.

After changing the date and time, apply the settings, usually this is done by pressing the "F10" key, you will be prompted to save the settings, press the "Y" and "Enter" key. To exit the BIOS press "Esc" and "Enter".

The computer will restart and the time will now work correctly, at least until the next battery change.

The topic that I decided to touch on in this article today is very popular among users. There are actually many reasons why the time and date on the computer get lost. There may be several reasons, but dealing with all of them does not present any serious difficulties.

As usual, I will tell you all about them in detail, after which you can determine what happened to windows settings on your computer. Here we go?

Battery

The main reason when you have time problems is the battery in your device... It would seem that the computer is working, the time is right, but after the reboot everything gets lost and of course it is a little scary. Due to the battery, which is a necessary part in the computer, you may have such problems.

When you turn off your computer, where do you think the computer or laptop remembers the time from? That's right - a battery! Of course, this battery is needed not only for the computer to remember the time, but also for the safety of data in the BIOS. As you can imagine, the battery has a tendency to discharge and therefore sometimes needs to be replaced.

Motherboard

It is possible that you have problems with motherboard... The solution is, of course, simple: the first is to test and the second is to replace. A motherboard does not cost little money, so consider whether it is worth replacing at all, or consider buying a new computer. After all, problems with the motherboard happen due to a long service life, that is, it is possible that your computer is a little outdated. But if your computer is under warranty, then you can use it so as not to waste money and not to understand yourself.

Also, a breakdown of the motherboard may be accompanied by automatic shutdown computer or just reboot. If you recently noticed such actions on the part of your computer, then you need to test motherboard or contact the service center to identify the cause.

Viruses

But what to do in the most incomprehensible situation? I mean the case when you did everything that I said above, and the question of why the time and date is lost on the computer remained unresolved. There are viruses that can change the time. This, of course, may sound very trite, but still, to be 100% sure, download the Dr. WebCureit. Check your system with it for malware.

I wrote about one of these utilities on my blog: "". And for the future, take a note: do not open suspicious links and install the antivirus on which it is configured automatic update anti-virus databases.

Wrong time zone

To do this, left-click on the icon with the time and date in the lower right corner of the screen, and in the window that appears with the clock picture, click on the inscription "Change the date and time settings."

On the "Date and Time" tab, we find the "Change time zone" button.

In the window that appears, change the time zone where you are now. Then click "OK". Normal time should now be displayed.

However, this is our manual setting does not end. The fact is that the computer still continues to support the function of synchronizing the time with the Internet, and it is possible that your time is not synchronized. You have not yet closed the "Date and Time" window. This time we are interested in the "Internet Time" tab, it contains the "Change parameters" button. Click the "Update Now" button and click "OK".

Now time should show just as much as it really is. You can also remove synchronization, but the first option will be more correct.

That's all I wanted to tell you about this. I hope that now the computer will always show you the correct time. And I say goodbye to you until the next meeting.
