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

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
• Harddiskdrive
• Opticaldrive
• Keyboard,Mouse(wired)
• Powercord

safety information” in the Safety and Warranty Guide that was included with your
computer. If you no longer have this copy of the Safety and Warranty Guide, you
