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 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:
• Memorymodules
• Harddiskdrive
• Opticaldrive
• Heatsink,Fan
• CPU

Safety information for replacing CRUs
Do not open your computer or attempt any repairs before reading the “Important
safety information” in the Safety and Warranty Guide that was included with your
computer. An electronic copy of the Safety and Warranty Guide can also be
obtained online from the Lenovo® Support Web site at:
