Hardware Replacement 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®.

The description of the TV-Tuner card in this manual applies only to those computer
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
• Keyboard, Mouse (wired)
• Power cord, Power adapter
