A common event is turning on the computer. No unpleasant noises.
No horrible flashes.
But here's the trouble! The clock in the corner of the screen shows some incomprehensible time.
The date is also from somewhere in the past.
The clock on the computer was lost. Setting the exact time and the correct date will not change the situation fundamentally. The clock will go immaculately until you turn off the computer. The new inclusion - and again the time is knocked down.
Do not be scared. It's not a virus. And not an operating system problem. Bill Gates is not at fault at all. And the reason for this is only a small battery on the motherboard.
Any computer has a special memory, whereMain settings and configuration data are stored. Remember them always, even when the computer is turned off. But to store these settings, you could do without a power source. There is another task. In a de-energized computer, the clock must constantly tick. You can turn off the computer from the outlet, move it to the other end of the city. And in this completely lifeless body, the counting of fleeting moments continues.
The clock in the computer is needed not only to know,what time is it now. 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.
In any electronic watch there is a battery. She also has a computer clock. And, like any battery, the charge in it ever ends. Although it is enough for years. There are batteries that have served for almost ten years. Therefore, the loss of sense of time occurs only with older computers.
What to do?
In fact, nothing terrible has happened. Buy the item CR2032 in the store. Disconnect the computer from the network. Remove the cover and look for the same battery on the system board. Found? It is easily removed from the special fastener with a small flat screwdriver. Just do not break anything. Carefully remove the old battery and also carefully, observing the polarity, insert a new one into its place.
Assemble the computer and turn it on. Now, after setting the exact time and the correct date, the clock will not go down anymore. At least the next few years.
You can synchronize your computer clock withServer of time on the Internet. The readings of the computer clock will be updated in accordance with the reference clock, which guarantees the accuracy of the readings.
If the problem persists, then either you did something wrong, or you have a problem with the motherboard. And then it's better to contact the service center.
Although it may be worth it to start right away?
