An ordinary event is the turning on of the computer. No annoying noise. No awful flares. But here's the trouble! The clock in the corner of the screen shows some strange time. The date is also from somewhere in the past.
Clock stopped
The clock on the computer is out of order. Setting the exact time and date will not fundamentally change the situation. The clock will run flawlessly until you turn off your computer. A new inclusion - and again the time is knocked down.
Don't be alarmed. This is not a virus. And not an operating system problem. Bill Gates is not at all to blame for this. And the reason for this is only a small battery on the motherboard.
Battery
Every computer has a special memory where basic settings and configuration data are stored. You must always remember them, even when the computer is turned off. But in order to store these settings, one could do without a power supply. There is another challenge. In a de-energized computer, the clock must constantly tick. You can turn off your computer from the outlet, move it to the other end of the city. And in this completely lifeless body, the account of the flew by moments continues.
A clock in a computer is needed not only to know what time it is. For the file system, information about the current time and date is very relevant. The operating system needs to know when each file is created or modified.
Any electronic watch has a battery. There is also a computer clock. And, like any battery, it ends up running out of charge sometime. Although it lasts for years. There are batteries that have served for almost ten years. Therefore, the loss of the sense of time occurs only with older computers.
What to do?
In fact, nothing terrible happened. Buy a CR2032 cell from a store. Disconnect your computer from the network. Remove the cover and find the same battery on the system board. Found it? It can be easily removed from the special mount using a small flat screwdriver. Just don't break anything. Gently remove the old battery and, just as carefully, observing the polarity, insert the new one in its place.
Build your computer and turn it on. Now, after setting the exact time and the correct date, the watch will no longer go astray. At least for the next few years.
You can synchronize your computer clock with an Internet time server. The computer clock will be updated according to the reference clock to ensure that the readings are accurate.
If the problem persists, then either you did something wrong, or you have a problem with the motherboard. And then it is better to contact the service center.
Although maybe it was worth starting with this right away?
