Avant de retirer une unité remplaçable en clientèle, mettez le système hors tension, débranchez tous les cordons d’alimentation des socles de prise de courant, retirez la batterie et déconnectez tous les cordons d’interface.
Page 20: Safety Information
Safety information Safety information The following section presents safety information with which you need to be familiar before you service a ThinkPad computer. General safety Follow these rules to ensure general safety: v Observe good housekeeping in the area of the machines during and after maintenance.
Page 21: Electrical Safety
Safety information v After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective. v Reinstall all covers correctly before returning the machine to the customer. v Fan louvers on the machine help to prevent overheating of internal components.
Page 22 Safety information – Ensure that another person, familiar with the power-off controls, is near you. Attention: Another person must be there to switch off the power, if necessary. – Use only one hand when working with powered-on electrical equipment; keep the other hand in your pocket or behind your back.
Page 23: Safety Inspection Guide
Safety information Safety inspection guide The purpose of this inspection guide is to assist you in identifying potentially unsafe conditions. As each machine was designed and built, required safety items were installed to protect users and service personnel from injury. This guide addresses only those items.
Page 24: Handling Devices That Are Sensitive To Electrostatic Discharge
Safety information 8. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with. Handling devices that are sensitive to electrostatic discharge Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD.) ESD damage can occur when there is a difference in charge between objects.
Page 25: Grounding Requirements
Safety information – Use the round ground prong of the ac plug on ac-operated computers. Grounding requirements Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.
