It is intended only for trained servicers who are familiar with Lenovo computer products. Before servicing a Lenovo product, be sure to read the Safety Information in Chapter 2 “Safety information” on page 3. Chapter 7 “Symptom-to-FRU index” on page 61 and Chapter 10 “Additional service information” on page 127 are not specific to any machine type.

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.
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.
5. Check for any obvious alterations. Use good judgment as to the safety of any alterations. 6. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or other liquids, or signs of fire or smoke damage. 7.
