these types of CRUs include the keyboard, the mouse, any USB device, and the power cord. Other

disk drives, and optical drives.
• Optional-service CRUs: These CRUs are isolated parts within the computer and are concealed by an
access panel that is typically secured by more than two screws. Once the access panel is removed, the
