During a routine inventory, you located an old computer that hasn't been utilized in quite a long time. During testing, you discover that the CMOS battery is dead. Which of the following is a common indicator of this issue?
The CMOS battery provides power to the motherboard's CMOS chip, which stores BIOS settings like the system date, time, and hardware configuration while the computer is turned off. If the battery dies, these settings are lost. The most common and immediate symptom is that the system clock resets to a default value, resulting in an inaccurate system date and time upon startup.
