What to do if the computer time is always wrong:
1. First of all, eliminate the phenomenon that the motherboard power supply is out of power and the computer time is wrong, if your computer will become 00:00 after each restart, it means that your computer motherboard battery needs to be replaced. After the replacement, it will solve the situation that the computer time is always wrong.
2. If there is no problem with the hardware, we need to proofread the time and synchronize the Internet time service.
3. Click the time in the lower right corner of the computer to bring up the time and date attributes.
4. Click "Time Zone", select "(GMT+08:00) Beijing, Chongqing, Hong Kong Special Administrative Region, Urumqi", and click "Apply".
5. In the state of networking, select the "Internet Time" tab, check "Automatically synchronize with the Internet time server", and click the "Update Now" button.
6. Please wait for Windows to sync.

Oh yes, you test it in a few minutes. Time has changed again, and it is the same as the time of the system.

I don't know if I don't see it, and I'm shocked when I see it.
It doesn't matter if you have this time, but the antivirus software you install has a relationship, don't install two antivirus and defense software at the same time, your QQ butler and Kingsoft Guardian are the same type, uninstall one, you can be smoother!

1. It may be a virus, try to kill the virus, preferably in safe mode. 2. You change the time first, and then "run" - enter - windows settings - security settings - local policy - user rights assignment - find and change the system time - double click - delete all the inside (there should be a sdministrators and power users in it) and then restart the time should not be changed.

1. The CMOS battery of the motherboard loses power, and the voltage should be within the range, otherwise it will not remember;
2. I once found out when I missed the time;
3. The Internet is poisoned.
-
That's because Windows Defender itself doesn't start at the same time.
-
This is normal, as some new updates will start automatically when you boot up your phone.
-
If you optimize your computer, it will boot up faster.
-
The time of self-startup is not the same.
-
If it's done after changing it, it's okay to use it at the time, but every time I turn it on again, I find that the time is not right, that is, there is a button battery on the motherboard that is out of power, and you can replace it
If the time changes when you use it, then you need to see if the system or the software running on the boot has a virus or something

What time does it start to display?,In this case,Most of the reasons are because the motherboard battery of the laptop is out of power.,Generally change a battery.,And then go into the BIOS to set it up.,If the system time lasts wrong.,There may also be a problem with the system.,It is recommended to redo the system.。

The motherboard pool of the notebook is out of power, and it can't be saved, just change the battery!
-
It is estimated that the internal battery is dead.
-
Just set it to be the same as the Internet.

1.The coin cell battery on the motherboard does not provide power properly. The solution requires replacing the battery.
If the computer time returns to the initial state every time it is turned on, that is, the state time when the computer is bought. And every time you set it, the next time you turn on the computer, the time is always wrong, just like our watch, without the stupid battery power, it will stop every time. Similarly, computer system time is stored on the BIOS, which is powered by a coin cell battery on the motherboard.
Let the time with regret continue to accumulate, if the battery is dead, the time will not accumulate.
2.The time is inaccurate due to a virus in the computer. You can use Kingsoft Poison's Time Protection Assistant or 360 Guardian to clean it up.
Open Kingsoft Poison Tyrant, select System Tools in the Security Treasure Chest, and then you can find the Time Protection Assistant. There is also a small function of time protection inside the front plexus 360 guard.

It's very likely that the motherboard battery is dead! You'll have to change the battery. When you open the case and see the motherboard, there is generally one that looks like a coin, which may lie flat or on its side, and there is a small buckle next to it, which can be pressed to get out.
Watch shops, computer city everywhere, about 5 yuan to pick at will.
As for the BIOS settings, the BIOS manufacturers of different motherboards will be different.
If you're using the AWORD BIOS, just boot it up and keep pressing the "Del" key to enter.
After entering the BIOS, turn off "Drive A" in the "Standard CMOS Setup", that is, in the standard CMOS settings; At the same time, set "holt on", i.e., pause items, to "no errors", i.e., no errors are paused. Basically, it's fine.
Just press F10 twice and hit enter.
In fact, I personally think that there is no need to set up the BIOS to change the computer battery, if you are prompted to press F1 when you turn on the computer, you can set it according to what I said above!

You should be talking about CMOS batteries, CMOS stands for Complementary Metal Oxide Semiconductor. It is used to remember your system time as well as BIOS settings. If the power is out, it will cause your computer system time to zero every time you turn on and you will need to reset it.
The BIOS information will also be restored to its original value.

Don't talk nonsense on the first floor, this is obviously the motherboard BIOS battery is dead, there is a coin cell battery on the motherboard, you can see it when you open it, just replace it.
-
I guess your motherboard electronics are out of power. Turn it off, unplug the power cord, turn on the main unit, and replace the electronics on the motherboard.
-
The battery of the motherboard, but my own question is:
Laptop with win7,External hard disk with ubuntu,Once you use ubuntu to transfer back to win7 the time is wrong,Who knows why?
-
Apparently the motherboard battery is dead. Buy a battery to replace it, a few bucks.
Time is not lost when the machine is running, because there is a power supply to power the timer. At the same time, the battery may be charged with a small amount of electricity (non-rechargeable batteries can also be charged in small amounts, which is risky), and there is no problem with a short shutdown time, but after a long time, that bit of power will be consumed, so the BIOS is reset again.

The CMOS battery is dead, replace the battery.
Computer shutdown abnormalities can be analyzed from the following aspects: 1. Computer viruses: network viruses were rampant in the past, and now you basically don't need to consider this (solution: reinstall the system). >>>More
