Why is the computer clock always inaccurate?

I've got a virus.

The virus modifies the time to stop the Kaba operation.

Solution. 1. Enter in the "Start Menu" - Run" (you can also use shortcut key: win+r), open Group Policy, still select "Computer Configuration - Windows Settings" - Security Settings - Local Policy - User Rights Assignment - Change System Time (right), and then double-click (or right-click and select "Properties") to open the "Update System Time Configuration" property dialog box, delete all the permission user names in it, and then click OK to restart the computer.

2. Let's take a look at the restart of the computer, manually verify whether the settings just now take effect

a, double-click the time in the lower right corner of the taskbar and double-click the "Time and Date" option in the control panel, and the system will pop up a prompt: "You don't have the appropriate privileges, so you can't change the system time".

b, try in the command prompt, enter cmd in the run, open the command prompt, enter the date command to display the current date, and then enter the new time: 1980-2-3, and then press enter, prompt: "the client does not have the required permissions", that is, it cannot be changed.

3, Okay, here the system setup is complete, then run the virus, look, Kaba will not fail, in order to determine the situation, restart the computer, the result is still the same, Kaba runs the monitoring as usual.

This method can prevent any modification of the system date and time to invalidate the Kaba monitoring, and at the same time, it can also prevent the Caikuro invasion from invalidating the Kaba by modifying the time!

This is obviously the battery is dead, but you said that you have replaced, then it may be a motherboard problem, you first take down the battery you replaced to measure the voltage, if there is no power, maybe your motherboard is leaking.

Redo the system, if there is still a problem, it should be a motherboard problem.

The battery on the motherboard is broken, try replacing it.

Poor contact, right?

Is the shrapnel connected to the battery oxidized?

There are several possible reasons why a computer clock is not accurate:

1.Low battery: The computer clock needs a certain amount of power to maintain accuracy, and if the battery is low, it will affect the normal operation of the clock.

2.Time synchronization is not accurate: The computer's clock is usually synchronized with the time server on the Internet, if the network connection is unstable or the time server has a problem, it will cause the computer clock to be inaccurate.

3.System Errors: Sometimes there will be errors in the computer system, such as failed operating system update, virus infection, etc., which may cause the computer clock to be inaccurate.

4.Hardware damage: If your computer's hardware fails, such as a motherboard or power supply problem, it can also cause your computer to have its clock inaccurate.

In order to avoid the problem of inaccurate computer clocks, you can do the following:

1.Replace the battery in time to ensure that the power is sufficient;

2.Avoid errors in the operating system and update the system regularly;

3.Use a reliable time server for time synchronization;

4.Clean the inside of your computer regularly to avoid hardware failures.
