Why does my computer go out of clock when it shuts down?

It's not a big problem, it's because the motherboard's battery is dead, I'm like this now, but I don't know if I should change it, if your computer is a desktop, you can open the case yourself, find a button battery on the motherboard, remove it, and replace it with a new one! If it's this book, it's more troublesome, and I don't know how to change it! You have to go to a special repair department, after all, the notebook is very expensive, don't repair it!

If the battery doesn't last long and dies, it means that your motherboard is leaking and you need to repair the motherboard If your motherboard and battery have been used for a long time, it is recommended that you buy a battery first and try it.

The BIOS battery on the motherboard is dead.

Replace the battery and you're good to go.

The battery of the main version is dead, just replace it.

The motherboard battery is dead, replace it

It is generally a problem with the battery, which can be bought in the computer city.

Change the battery of the motherboard, it is sold in the computer city, a 3-5 yuan, the motherboard battery is divided into two kinds, one thick, one Pu, it is best to take the battery on the original motherboard to compare.

If the battery is not allowed to last less than half a year, it is better to repair your motherboard

The battery is dead, just change the battery.

This kind of battery is sold everywhere, 3 yuan a piece.

That's because the computer doesn't turn on the automatic time, and the specific steps are as follows:

1. First on the computer desktop.

to find the time bar in the lower right corner, right-click the mouse to the time.

2. At this time, there is a selection bar, find the adjustment date and time of the second row of the closed large, and click it.

3. The figure is the interface for setting the car rolling vertical time, the interface includes the setting of date and time, and then the automatic setting time in the figure can be ticked with the automatic setting time zone.

4. Go back to the desktop and find that the time is right, so that even if the shutdown time will not change.

There are 3 reasons why the computer is shut down or restarted for an inaccurate time:

1. The motherboard battery is dead.

2. There is virus invasion.

3. The time modification permission is not enabled.

Solution: 1. The motherboard battery (CMOS) is out of power: You can enter the BIOS to load the optimized preset value through the CMOS checksum error in the boot bridge, and if the total power is turned off and turned on again, it proves that the battery is indeed dead.

This situation requires the replacement of the coin cell battery.

2. There is a virus invasion: after the computer changes the time under Windows, it will quickly jump to an wrong time. This case is the virus, and the purpose of modifying the time is to get the antivirus software.

3. Time modification permission: You need to determine whether the currently logged in user has the permission to modify the time. Go to the local policy [Start --Run" or "Control Panel".

Management Tools Local Security Policy "] is delayed, as shown in the following figure:

This solution is applicable to XPVISTAWIN7 system.

Problem Description]:

The time in the lower right corner is out of sync.

Cause Analysis]:

The battery is dead. 2.The time of the virus is modified.

Easy Steps]:

Procedure]:

Solution 1: Install a 360 time protector.

360 Time Protector.

Figure 13After installation, first click [Allow Time Modification], and then adjust the system time to the current correct time. Click OK to save the time and date information, and then click Prohibit time modification.

The next time you start it, the time will not be automatically changed. (Figure 2).

Figure 2 Option 2: Replace the BIOS battery.

If the BIOS battery of the computer motherboard is out of power and the time information cannot be saved normally, you can find a professional physical repair shop to replace the BIOS button battery on the motherboard. (Users who have no experience in disassembling the machine are advised not to open the chassis at will to prevent hardware damage caused by misoperation).

After the shutdown, the time did not move for the following reasons: first, the BIOS is out of battery, update the BIOS battery in time, and second, check the network event synchronization. Adopt it.

Hello, this should be your BIOS battery out of charge.

You can replace the coin cell battery of this motherboard.

If it is not convenient to replace it now, you can also use the PC Accelerator function of PC Manager to set the Windows Time service to start.

In this way, when you are connected to the Internet, the system will automatically proofread the time, and if you have any questions in the future, please come to the computer manager platform to ask questions, and we will do our best to answer for you.

The date or time of the computer is always inaccurate, mainly due to two reasons.

1. The computer has not been turned on for a long time, and the battery power of the motherboard is exhausted, resulting in the system time being cleared. After turning on the computer again, the date will be re-calculated from the factory date of the motherboard, and the time will be re-timed from 00:00:00. After the power is turned off again, the next time the device is turned on, the timing will be repeated again.

Second, the clock generator frequency on the motherboard is not accurate enough, resulting in fast or slow system time. However, this only leads to inaccurate time, not incorrect date.

The coin cell battery on the motherboard is dead, try another one.

The reasons why time does not go away after the computer is turned off are as follows:

1. The computer has not been turned on for a long time, and the battery power of the motherboard is exhausted, resulting in the system time being cleared;

2. The clock generator frequency on the motherboard is not accurate enough, resulting in fast or slow system time;

3. The computer system is incompatible with some applications;

4. Some applications in the computer carry viruses.

Hello, change the computer motherboard battery. It may be that the computer motherboard computer is out of power. The model number is a 2032 coin cell battery.

CMOS (originally meaning complementary metal oxide semiconductor storage hub, is a raw material used in the manufacture of integrated circuit chips on a large scale) is a readable and writable RAM chip on a microcomputer motherboard, which is mainly used to store the hardware configuration of the current system and the operator's setting of certain parameters (including clock). The CMOS RAM chip is powered by the system through a backup battery, so whether it is in a shutdown state or in the event of a system power failure, the CMOS information will not be lost.

Since the CMOS RAM chip itself is only a memory and only has the function of saving data, the setting of various parameters in the CMOS must be through a special program. Early CMOS setup programs resided on floppy disks (e.g., IBM's PC AT models) and were inconvenient to use. Nowadays, most manufacturers have made the CMOS setting up and upgrading program in the BIOS chip, and it is very convenient to set the system by pressing a specific key when the system is turned on, so this CMOS setting is usually called BIOS setting.

The difference and relationship between BIOS settings and CMOS settings.

The BIOS is an EPROM or EEPROM chip on the motherboard, which contains important information about the system and a setup program for setting system parameters (BIOS Setup program); CMOS is a readable and writable RAM chip on the motherboard, which contains specific parameters about the system configuration, and its content can be read and written through the setup program. The CMOS RAM chip is powered by a backup battery, so even if the system loses power, the information will not be lost. BIOS is both related and different from CMOS :

The system setup program in the BIOS is the means to complete the CMOS parameter setting; CMOS RAM is both the place where the BIOS sets the system parameters and the result of the BIOS set system parameters. Therefore, the full statement should be"The CMOS parameters are set through the BIOS setup program"。Since BIOS and CMOS are both related to the secret of the system settings, the statement that BIOS settings and CMOS settings are caused in the actual use process actually refer to the same thing, but BIOS and CMOS are two completely different concepts, so they must not be confused.
