Three possibilities and solutions of inaccurate computer time

There are only three possibilities when computer time is not allowed: 1, the motherboard battery is dead, there is a virus, and there is something wrong with the motherboard. The corresponding solution: 1, replace the motherboard battery, the model is CR2032, button-shaped lithium battery. 2, anti-virus. 3. Send the motherboard for repair or replacement. Let's talk about how to judge these three situations:

be poisoned

If you can't change the time under windows, or just change it and jump to a wrong time, it must be poisoned.

The motherboard battery is dead or there is something wrong with the motherboard.

If you can modify the time under windows, but the time is wrong after restarting. Then modify the system time again, restart the computer, and enter the BIOS to check the time displayed by the BIOS. If this time is wrong, it means that the motherboard battery is dead or there is something wrong with the motherboard. If the time is correct at this time and the time is wrong after entering windows, it means a virus.

Main board problem

If the BIOS time is wrong and the problem is not solved after replacing the battery, then it is a motherboard problem. Usually there is something wrong with the small chip, capacitor or circuit, so just send it for repair.
