Question

an employee complains that every time they turn their computer off, the computers 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? the cmos battery has failed. the cmos chip on the motherboard is loose. the cmos settings are not being saved before the computer powers off. the cmos chip is failing. i want to review this question later (optional)

Explanation:

The CMOS (Complementary Metal - Oxide - Semiconductor) chip on a computer stores settings like time and date. When the CMOS battery fails, it can't maintain these settings. When the computer is powered off, the settings are lost and reset to default values (like 12:00 p.m. and January 1, 1990). A failed CMOS chip or incorrect CMOS settings not being saved can also cause issues, but a dead battery is the most likely cause among the options.

Answer:

The CMOS battery has failed.
