What is a CMOS Battery?
A CMOS battery is a small circular battery located inside your Dell laptop. It powers the CMOS memory component, which stores the system’s BIOS settings, including the date, time, and hardware configurations.
When you power off your laptop, the CMOS battery ensures that these settings are retained even when there’s no external power source. Over time, this battery may run out of power or lose its effectiveness, resulting in issues like time and date settings resetting every time you turn on your laptop.
