The desktop CMOS battery, also known as the motherboard battery or BIOS battery, is a small coin cell battery that provides power to the complementary metal-oxide-semiconductor (CMOS) chip on the computer's motherboard. This battery is responsible for maintaining certain system settings, including the date and time, BIOS settings, and hardware configurations, even when the computer is powered off. Over time, the CMOS battery can lose its charge, leading to issues such as incorrect system time, BIOS settings resetting to default, or startup errors. When this occurs, replacing the CMOS battery with a new one of the same type (usually a CR2032 lithium battery) resolves the issue and restores proper functionality to the system.

Foam cleaners are cleaning products that produce foam when applied to surfaces. They are commonly used for cleaning various surfaces such as upholstery, carpets, rugs, and even certain hard surfaces like countertops and appliances. Foam cleaners typically contain surfactants, which are chemicals that help loosen dirt and grime, making it easier to remove. They can be particularly effective for lifting stains and dirt from fabrics without saturating them with liquid. Foam cleaners come in various formulations for different purposes and surfaces, such as carpet foam cleaners, upholstery foam cleaners, and general-purpose foam cleaners. It's important to follow the manufacturer's instructions when using foam cleaners to ensure effective and safe cleaning.
