The exact time on the computer is displayed using a special microcircuit, the power of which is provided by the mains when the computer is turned on and a small battery when it is off. The reasons for the faults in the displayed times are usually the same for each computer.
Hardware problems
The primary reason that the wrong time is displayed when you turn on the computer and boot the system is the battery life in the case, which makes the computer unable to maintain the correct course of time after it is turned off. The battery needs to be replaced. To do this, turn off the computer from the network and disconnect the power cable from the system unit. Unscrew the screws that hold the side cover of the device and pull out the cover itself. Find the battery and fold the holder to remove it. Place a new battery in the housing. Usually a 3V battery is sufficient.
Make sure your computer's power supply is strong enough. In some cases, due to the incorrect selection of this item, the computer may malfunction, due to which it starts to display the wrong time.
If, even after replacing the battery, the time is still incorrectly set, contact the technical specialists: the problem may be an outdated motherboard that is out of order or conflicts with newer hardware.
Operating system problems
Make sure you set your time zone correctly. Typically, these settings are entered during the installation of the system, but later they can be set by double-clicking the left mouse button on the clock in the lower right corner of the screen and going to the "Time zone" tab. Remember that if you set the wrong time zone, the system will automatically set the time corresponding to it.
Viruses can be the cause of incorrect time setting by the system. Check your computer's hard drive and removable media with an antivirus program and remove any malicious objects found.
Please note if time synchronization with Internet services is enabled in the time settings. It is advisable to set the Microsoft website as a time source. In this case, it will become accurate and will be automatically corrected every time you connect to the Internet.
Check if any software is getting out of time. Some programs have their own time settings and, after installation, configure the system to suit their needs, ignoring the settings set by the user. It is advisable not to install suspicious applications downloaded from suspicious Internet sources on your computer.
