This manual is intended only for trained service personnel who are familiar with Lenovo computer products. Before servicing a Lenovo computer product, be sure to read “Important Safety Information” on page 1. Chapter 7 “Symptom-to-FRU Index” on page 61 and Chapter 10 “Additional Service Information” on page 113 are not specific to any machine type and are applicable to all ThinkCentre computers.

Important: Use only approved tools and test equipment. Some hand tools have handles covered with a soft material that does not insulate you when working with live electrical currents. Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges. Do not use this type of mat to protect yourself from electrical shock.
Page 11: Safety Inspection Guide, Handling Electrostatic Discharge-sensitive Devices

Safety inspection guide The intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these products. Each machine, as it was designed and built, had required safety items installed to protect users and service personnel from injury. This guide addresses only those items. However, good judgment should be used to identify potential safety hazards due to attachment of features or options not covered by this inspection guide.
Page 12: Grounding Requirements, Safety Notices (multi-lingual Translations)

• Wear a grounded wrist strap against your skin to eliminate static on your body. • Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when you are wearing a wrist strap. • Use the black side of a grounded work mat to provide a static-free work surface. The mat is especially useful when handling ESD-sensitive devices.
