The following section contains the safety information that you need to be familiar with before servicing an IBM mobile computer.
Ensure you can stand safely without slipping. Distribute the weight of the object equally between your feet. Use a slow lifting force.
Never move suddenly or twist when you attempt to lift. 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. Make sure that your sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it. Attention: Metal objects are good electrical conductors.
Replace any safety device that is worn or defective. 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. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly. If you cannot unplug it, ask the customer to power-off the wall box that supplies power to the machine and to lock the wall box in the off position. Attention: Another person must be there to switch off the power, if necessary.
Attention: An electrical shock can occur only when there is a complete circuit. By observing the above rule, you may prevent a current from passing through your body. Observe the special safety precautions when you work with very high voltages; these instructions are in the safety sections of maintenance information.
Use extreme care when measuring high voltages. First, check that it has been powered off. Examples of these hazards are moist floors, nongrounded power extension cables, power surges, and missing safety grounds.
The surface is conductive; such touching can cause personal injury and machine damage. 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. You should use good judgment to identify potential safety hazards due to attachment of non-IBM features or options not covered by this inspection guide. If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem. Safety information v 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. Begin the checks with the power off, and the power cord disconnected. Check exterior covers for damage loose, broken, or sharp edges. Power-off the computer. Disconnect the power cord. Check the power cord for:. A third-wire ground connector in good condition.
Use a meter to measure third-wire ground continuity for 0. The power cord should be the type specified in the parts list. Insulation must not be frayed or worn.
Check for any obvious non-IBM alterations. Use good judgment as to the safety of any non-IBM alterations. 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.
Check for worn, frayed, or pinched cables. Check that the power-supply cover fasteners screws or rivets have not been removed or tampered with. 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. Use product-specific ESD procedures when they exceed the requirements noted here. Most clothing is insulative and retains a charge even when you are wearing a wrist strap.
The mat is especially useful when handling ESD-sensitive devices. The use of a grounding system is desirable but not required to protect against ESD damage. You can use coax or connector-outside shells on these systems. 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. They are also sold separately as options. The drive is certified in the U.
