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 Chapter 2 “Safety information” on page 3. Chapter 7 “Symptom-to-FRU index” on page 63 and Chapter 11 “Additional service information” on page 157 are not specific to any machine type.

Page 8 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 an electric shock.
Page 9: Voltage-Selection Switch
Voltage-selection switch Some computers are equipped with a voltage-selection switch located near the power-cord connection point on the computer. If your computer has a voltage-selection switch, ensure that you set the switch to match the voltage available at your electrical outlet. Setting the voltage-selection switch incorrectly can cause permanent damage to the computer.
