Note: The service procedures are designed to help you isolate problems. They are written with the assumption that you have model-specific training on all computers, or that are familiar with the computers, functions, terminology, and service information provided in this manual.

Safety information

The following section contains the safety information that you need to be familiar with before servicing an IBM mobile computer.

General safety

Follow these rules to ensure general safety:

vObserve good housekeeping in the area of the machines during and after maintenance.

vWhen lifting any heavy object:

1.Ensure 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. Do not attempt to lift any objects that weigh more than 16 kg (35 lb) or objects that you think are too heavy for you.

vDo not perform any action that causes hazards to the customer, or that makes the equipment unsafe.

vBefore you start the machine, ensure that other service representatives and the customer’s personnel are not in a hazardous position.

vPlace removed covers and other parts in a safe place, away from all personnel, while you are servicing the machine.

vKeep your tool case away from walk areas so that other people will not trip over it.

vDo not wear loose clothing that can be trapped in the moving parts of a machine. Ensure that your sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it.

vInsert the ends of your necktie or scarf inside clothing or fasten it with a nonconductive clip, approximately 8 centimeters (3 inches) from the end.

vDo not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing.

Remember: Metal objects are good electrical conductors.

vWear safety glasses when you are: hammering, drilling soldering, cutting wire, attaching springs, using solvents, or working in any other conditions that might be hazardous to your eyes.

vAfter service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective.

vReinstall all covers correctly before returning the machine to the customer.
