Why is the time reset on your computer

Sooner or later on any computer begins to reset the time. Together with the reset of the time, the BIOS settings are also reset. These reset creates a lot of problems to the user. In this article you will find out why the time is reset on the computer and how this problem can be solved.

This problem arises because of the battery on the motherboard. This battery is responsible for keeping BIOS settings and operating the system watch. Over time the battery consumes its resources, and eventually it does not work. And with the non -functional battery the computer will return to the default BIOS settings at each computer stop.

How do I find out if the battery on the motherboard has consumed its resources

• At each stop of the computer, the time is reset on the computer. In addition, the date is changed.
• At each stop of the computer the BIOS settings are reset.
• At each start of the computer you are asked to press the F1 or F2 keys.
• There will also be problems with running programs, the antivirus will report the expired license, and the browser will refuse to open some sites due to non-actual certificates.

How to solve the problem with reset time on computer

To solve this problem you must change the battery on the motherboard. This battery is called CR 2032and can be bought in computer stores. Not all sellers know what the «CR 2032 battery» is. Thus, you can only go to the store and ask if they have the «motherboard battery». You can also remove the old battery and show the seller from the store.

To change the battery on the motherboard must:

• Disconnects the computer from electricity. Disconnect the power cord from the system unit to be sure that the computer is disconnected.
• Remove the side lid on the left side of the system unit. Remove the two fixing screws from the back of the housing and remove the lid on the left side of the system unit.
• Find and remove the battery from the motherboard. To remove the battery you will have to press the small bow with a screwdriver.
• Mount the new battery. To mount the new battery just place it instead of the old battery. During installation you should hear a click.
• Close the system unit and start the computer.
• Check the new battery. Set the hour, turn off the computer and completely disconnect it from electricity. After this procedure the time should remain unchanged.

Conclusion

The problem of a computer constantly resetting its time and BIOS settings is a common issue that many users encounter, especially as the computer ages. This situation is typically caused by a failing motherboard battery, often referred to as the CMOS battery. This small battery plays a critical role in maintaining the BIOS settings and keeping the system clock running even when the computer is turned off. Over time, the battery depletes, and its inability to provide power leads to the loss of all stored configurations and a reset of the system clock each time the computer is restarted.

The consequences of a dead or weak CMOS battery extend beyond just an incorrect time. Users may notice problems with boot sequences, incorrect hardware detection, or persistent BIOS warnings at startup. Applications and system processes that rely on accurate time, such as scheduled tasks, software licenses, or network communications, can also be affected. Therefore, identifying and addressing this issue is essential to maintaining smooth computer operation.

Replacing the motherboard battery is generally a simple and cost-effective solution. The process usually involves opening the computer case, removing the old battery, and inserting a new one of the same type, typically a CR2032 lithium coin battery. After replacement, the BIOS can be reset to the user’s preferred configuration, and the system clock will continue to operate correctly.

In conclusion, if a computer begins to reset time and BIOS settings, the underlying cause is almost always a depleted CMOS battery. Timely replacement restores the system’s stability, prevents recurring configuration loss, and ensures accurate system time. Understanding this common hardware issue empowers users to troubleshoot effectively, maintain their systems, and avoid potential disruptions caused by incorrect BIOS settings or system time.
