Chapter 1. Safety information This chapter presents following safety information that you need to be familiar with before you service a ThinkPad notebook computer.
• Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly. • Do not work alone under hazardous conditions or near equipment that has hazardous voltages. • Disconnect all power before: – Performing a mechanical inspection – Working near power supplies – Removing or installing main units • Before you start to work on the machine, unplug the power cord.
Consider these conditions and the safety hazards they present: • Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal electrical shock) • Explosive hazards, such as a damaged CRT face or a bulging capacitor • Mechanical hazards, such as loose or missing hardware To determine whether there are any potentially unsafe conditions, use the following checklist at the beginning of every service task.
– When working on a double-insulated or battery-operated system, use an ESD common ground or reference point. You can use coax or connector-outside shells on these systems. – 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.
