The component on the motherboard that confirms all devices are in working order when the computer is powered on is the Power-On Self-Test (POST). During POST, the system checks hardware components such as the CPU, RAM, and storage devices to ensure they are functioning correctly. If any issues are detected, the POST will typically provide error codes or beep codes to indicate the problem. Once all checks are passed, the system proceeds to boot the operating system.
