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 the replacement of all parts. It is expected that trained service personnel are already able to replace cables, switches, and certain mechanical parts 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, and therefore does not apply to models without a TV-Tuner card.

This guide contains instructions for replacing the following parts:
