Question

An employee complains that every time they turn their computer off, the computer's time is set to 12:00 p.m., and the date is set back to January 1, 1990. Which of the following is the MOST likely cause of this anomaly? A) The CMOS chip is failing. B) The CMOS settings are not being saved before powering off the computer. C) The CMOS battery has failed. D) The CMOS chip on the motherboard is loose.

Answer 1

The computer resetting its time and date after being powered off is likely due to the CMOS battery failing. This battery is responsible for storing system time, date and basic settings, and when it fails, the computer cannot remember this information.

Step-by-step explanation:

The anomaly you're dealing with where the computer resets its time and date every time it is powered off is most likely due to the CMOS battery failing. The CMOS (Complementary Metal-Oxide-Semiconductor) battery is a component of your computer that stores information related to system time, date and basic settings. Without the power provided by the battery, the computer loses this information when it's turned off. When the CMOS battery fails or wears out, the computer can't remember the current date and time and reverts back to a default date. Therefore, the best option from your given alternatives is: C) The CMOS battery has failed.
