A typical symptom of a CMOS battery failure is the system's inability to retain BIOS settings, leading to incorrect date and time upon powering on the computer. Users may also experience boot errors or messages prompting them to enter setup or indicating that the system has lost its configuration. Additionally, hardware settings such as device priorities may revert to default, causing potential issues with system functionality.

A slot on the motherboard intended to hold the CMOS battery.
There are none. One is a battery which is used to provide passive power to the CMOS chipset to keep it from clearing itself.
The CMOS RAM battery is commonly referred to as the "CMOS battery." It is typically a small coin-cell battery, often a CR2032 lithium battery, that powers the CMOS (Complementary Metal-Oxide-Semiconductor) memory. This memory stores BIOS settings and system time when the computer is turned off. If the CMOS battery fails, users may experience issues with system settings and time retention.
