Why do I have to reset the date and time every time my computer is turned on?

There are only three possibilities for computer time inaccuracy:

1. The motherboard battery is dead.

2. There is a virus.

3. There is a problem with the motherboard.

Corresponding workaround:

1. Replace the motherboard battery.

2. Antivirus. 3. Send the motherboard for repair or replacement.

Let's talk about how to judge these three situations:

If the time cannot be modified under Windows, or it jumps to an incorrect time just after the modification, then it must be poisoned;

If the time can be changed under Windows, but the time is wrong after the restart. Then re-modify the system time, restart the computer, enter the BIOS to check the time displayed in the BIOS, if this time is wrong, it means that the motherboard battery is dead or the motherboard has a problem. If the time is right at this time, and the time is wrong after entering Windows, it means that it is a virus.

If the BIOS time is wrong, and the problem is still not solved after replacing the battery, then it is the fault of the motherboard, usually a very small chip, a capacitor or a circuit has a problem, just send it for repair.

Reboot press the DEL key to enter the BIOS, and select the first line of Standard CMOS Features

Use the arrow keys and the + and - keys to modify the date and time lines respectively;

For details, please refer to the motherboard manual for operation).

After the modification, press F10 to save and exit the BIOS, reboot into the system to see if the time is displayed normally.

The system time is inaccurate.

1. It may be that the CMOS battery is dead, please replace the battery.

2. If the battery is new or there is not much time to replace, it may be caused by poor contact of the CMOS battery, if so, stuff a small piece of copper into the contact point.

3. The time of the BIOS is not saved or saved, but it does not take effect. If so, there is a problem with the CMOS circuitry, including the motherboard-related circuitry and the CMOS that holds the BIOS program. If there is a problem with the motherboard circuit, it is recommended to repair it.

If it is caused by a virus, please check and kill it.

:** After installation, first upgrade to the latest version, then exit normal mode and reboot press F8 to enter safe mode. Open the software, click "System Scan", select all the scan results, and then click the "Perform Cleanup" button, if the software prompts you whether to "backup", select "Yes" (the backup is to prevent cleaning errors, if the system does not occur abnormal after cleaning, delete the backup), and follow the prompts.

The motherboard battery is dead, open the case, see the electronics on the motherboard, and replace it with the same one.

Your motherboard battery is dead, just replace one.

1. Consider whether there is a virus in the computer, use the security software on the computer to fully disinfect and fix it.

2. There may be a problem with the time setting of the computer. Find the time and date in the control panel.

3. Set the time zone as shown in the figure, be sure to see it clearly.

4. And set the computer time to keep the Internet in sync.

5. It may also be caused by the lack of power in the battery used for the storage time and BIOS settings of the motherboard, and it is recommended to replace the motherboard battery.

6. After booting up and pressing F8 to enter the safe mode, then exit, select the latest correct configuration and then turn it on, you can enter the normal mode (repair the registry).

7. If it really doesn't work, you can reinstall the system, which should solve the problem.

The computer time has to be reset every time it is turned on, the battery of the motherboard is dead, and the button battery of the motherboard can be replaced. In the computer, the motherboard battery is used to record the computer system time, BIOS settings, the motherboard battery we can also call the COMS battery, button battery.

The motherboard battery is usually CR2032 specification, if the motherboard button battery is out of power, then the system time will be restored to the factory date, and the BIOS settings will also be restored to the initial value, and we can replace the motherboard battery to solve the problem.

Buy a new button battery, the specifications are the same as the motherboard battery, the motherboard is usually CR2032 specifications, and then remove the button battery on the motherboard and replace one, the button battery is available in supermarkets, stores, and the Internet, and it can be done for a few dollars. If you replace the motherboard button battery and still can't save the system time and BIOS settings, then it may be a problem with the motherboard, if this does not affect the use, it is still not recommended to replace or repair.

The computer has to reset the time every time it is turned on, which is caused by the CMOS battery on the computer motherboard being out of power, when the computer is powered off, it relies on this battery power supply to maintain the setting information in the BIOS, including the time, so if the cmod battery is out of power, the time information is lost after the power is off, and it will become the default factory time when it is turned on again.

The solution to this problem is very simple, just replace the CMOS battery, and the operation is very simple, the user can do it by himself, first go to the computer store, bookstore or supermarket to buy a model CR2032 battery.

Then disassemble the bezel on the side of the case, find the CMOS battery on the motherboard, generally in a more conspicuous position, easy to find, if you can't find it, it may be blocked by the graphics card, you can remove the graphics card first, replace it with a new battery and then install it back.

After changing the new battery, turn on the computer, press Delete to enter the BIOS settings immediately when it is turned on, press F10 to save and exit, and automatically restart the computer.

The first consideration is whether there is a virus in the computer, use the security software on the computer to fully disinfect and fix it!

end precautions.

There are many reasons, follow the order to find it, if it really doesn't work, install the system, most of them will solve the problem!

This is the case every time you boot up, which is caused by the wrong BIOS settings. How to deal with it:

1. After booting up, keep pressing the delete button to enter the BIOS interface.

2. After entering the BIOS interface, select "Load Optlmized Defaults" in "Standard CMOS Features" and press Enter to confirm, 3. In the prompt box, select "OK".

Hello, glad you asked, your question was.

Why your computer.

Reset the time every time you turn it on.

This is mainly because:

A coin cell battery is built into the motherboard of the computer.

It provides energy to the computer after it is shut down.

Ensure the timer of the computer at this stage.

The counter is still working.

When the button battery is out of power, it naturally cannot work continuously.

You can take the case apart and replace a battery yourself.

That's because the battery on the motherboard is out of power, there is a button battery on the motherboard, which provides power to the motherboard BIOS, saves some BIOS parameters modified later, and it will return to the initial state when there is no power, and the time is also, just replace the battery.

It may be caused by abnormal system configuration, and can be solved by entering the boss mode of the computer and modifying the settings of the computer.

This situation may be caused by a dead coin cell battery on the computer's motherboard.

The reason why your computer has to reset the time every time you turn on it is entirely because you have not set up this function to synchronize with Beijing time, as long as you set it, there is no such problem.

Hello friends, judging from the description you gave, it should be that the computer is the motherboard's coms battery is out of power.

The motherboard battery is dead, or there is a problem with the motherboard. Replacing the battery can not be solved, changing the motherboard.

The battery is dead, replace it with a 3-volt battery.
