Safety information This chapter presents following safety information that you need to be familiar with before you service a ThinkPad Notebook.
General safety Follow these rules to ensure general safety: v Observe good housekeeping in the area of the machines during and after maintenance. v When lifting any heavy object: 1. Make sure that you can stand safely without slipping. 2. Distribute the weight of the object equally between your feet. 3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift. 4. Lift by standing or by pushing up with your leg muscles; this action removes the strain from the muscles in your back.
Electrical safety Observe the following rules when working on electrical equipment. 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.
v Do not touch live electrical circuits with the reflective surface of a plastic dental mirror. The surface is conductive; such touching can cause personal injury and machine damage. v Do not service the following parts with the power on when they are removed from their normal operating places in a machine: – Power supply units – Pumps – Blowers and fans – Motor generators – Similar units to listed above This practice ensures correct grounding of the units.
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 technicians from injury. This guide addresses only those items. You should use good judgment to identify potential safety hazards due to attachment of non-ThinkPad features or options not covered by this inspection guide.
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. Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the person handling the part are all at the same charge. Notes: 1.
