**Understanding the Function of CMOS Batteries**
CMOS, or Complementary Metal-Oxide Semiconductor, refers to a small, battery-powered memory chip on your computer’s motherboard. This **CMOS battery** is vital for storing essential system information, even when your computer is powered off. It reliably maintains settings such as the system time, date, and hardware configurations (like boot order). When this **CMOS battery** starts to lose power, you might notice issues like an incorrect system clock or your computer forgetting its boot sequence. Replacing an old **CMOS battery** often resolves these problems, ensuring your system starts up correctly and maintains accurate time.
