Which document provides the list of parts classified as CRUs?

The Hardware Maintenance Manual is the document that provides a detailed list of parts classified as Customer Replaceable Units (CRUs). This manual is specifically designed for technicians and service personnel, detailing which components can be safely replaced by customers without needing extensive technical support. It includes information about the identification, handling, and installation of CRUs, which typically consist of easily accessible parts like memory, hard drives, and batteries. This guidance empowers users to perform upgrades and replacements, thus improving the overall maintenance of their devices.

In contrast, the Service Manual primarily focuses on repair procedures and diagnostics for more complex issues that may require professional service intervention. The User Guide offers general product information and usage instructions, rather than detailed technical specifications or service guidance. Warranty Documentation outlines the terms and conditions of the warranty coverage but does not specifically identify CRUs or provide repair or maintenance protocols. Therefore, the Hardware Maintenance Manual is the most appropriate source for information regarding parts classified as CRUs.
