User Guide

Overview

This guide is intended to be used by customers who are replacing Customer 
Replaceable Units (CRUs) as well as trained service personnel who are replacing 
Field Replaceable Units (FRUs). In this guide, CRUs and FRUs will often be referred 
to as parts.

  Note: Trained service personnel should refer to the Hardware Maintenance 

Manual (HMM) for parts ordering information.

This guide does not include procedures for all parts. It is expected that cables, 
switches, and certain mechanical parts can be replaced by trained service 
personnel without the need for step-by-step procedures.

  Note: Use only parts provided by Lenovo®.

models that have the TV-Tuner card installed. It does not apply to those computer 
models that do not have the TV-Tuner card installed.

This guide contains procedures for replacing the following parts:
•  Memory modules
•  Hard disk drive
•  Optical drive
