Safety informationSafety informationThe following section contains the safety information thatyou need to be familiar with before servicing an IBMmobile computer.General safetyFollow these rules to ensure general safety:v Observe good housekeeping in the area of themachines during and after maintenance.v When lifting any heavy object:1. Ensure you can stand safely without slipping.2. Distribute the weight of the object equally betweenyour feet.3. Use a slow lifting force. Never move suddenly ortwist when you attempt to lift.4. Lift by standing or by pushing up with your legmuscles; this action removes the strain from themuscles in your back. Do not attempt to lift anyobjects that weigh more than 16 kg (35 lb) or objectsthat you think are too heavy for you.v Do not perform any action that causes hazards to thecustomer, or that makes the equipment unsafe.v Before you start the machine, ensure that other servicerepresentatives and the customer’s personnel are not ina hazardous position.v Place removed covers and other parts in a safe place,away from all personnel, while you are servicing themachine.v Keep your toolcase away from walk areas so that otherpeople will not trip over it.v Do not wear loose clothing that can be trapped in themoving parts of a machine. Make sure that your sleevesare fastened or rolled up above your elbows. If your hairis long, fasten it.v Insert the ends of your necktie or scarf inside clothing orfasten it with a nonconductive clip, approximately 8centimeters (3 inches) from the end.v Do not wear jewelry, chains, metal-frame eyeglasses, ormetal fasteners for your clothing.Attention: Metal objects are good electrical conductors.v Wear safety glasses when you are hammering, drilling,soldering, cutting wire, attaching springs, using solvents,or working in any other conditions that might behazardous to your eyes.v After service, reinstall all safety shields, guards, labels,and ground wires. Replace any safety device that isworn or defective.v Reinstall all covers correctly before returning themachine to the customer.12ThinkPad TransNoteDownloaded from www.Manualslib.com manuals search engine

Safety informationElectrical safetyObserve the following rules when working on electricalequipment.ImportantUse only approved tools and test equipment. Somehand tools have handles covered with a softmaterial that does not insulate you when workingwith live electrical currents.Many customers have, near their equipment, rubberfloor mats that contain small conductive fibers todecrease electrostatic discharges. Do not use thistype of mat to protect yourself from electrical shock.v Find the room emergency power-off (EPO) switch,disconnecting switch, or electrical outlet. If an electricalaccident occurs, you can then operate the switch orunplug the power cord quickly.v Do not work alone under hazardous conditions or nearequipment that has hazardous voltages.v Disconnect all power before:– Performing a mechanical inspection– Working near power supplies– Removing or installing main unitsv Before you start to work on the machine, unplug thepower cord. If you cannot unplug it, ask the customer topower-off the wall box that supplies power to themachine and to lock the wall box in the off position.v If you need to work on a machine that has exposedelectrical circuits, observe the following precautions:– Ensure that another person, familiar with thepower-off controls, is near you.Attention: Another person must be there to switchoff the power, if necessary.– Use only one hand when working with powered-onelectrical equipment; keep the other hand in yourpocket or behind your back.Attention: An electrical shock can occur only whenthere is a complete circuit. By observing the aboverule, you may prevent a current from passing throughyour body.– When using testers, set the controls correctly anduse the approved probe leads and accessories forthat tester.– Stand on suitable rubber mats (obtained locally, ifnecessary) to insulate you from grounds such asmetal floor strips and machine frames.Observe the special safety precautions when you workwith very high voltages; these instructions are in theIntroductionDownloaded from www.Manualslib.com manuals search engine13

Safety informationvvvvvvsafety sections of maintenance information. Useextreme care when measuring high voltages.Regularly inspect and maintain your electrical hand toolsfor safe operational condition.Do not use worn or broken tools and testers.Never assume that power has been disconnected froma circuit. First, check that it has been powered off.Always look carefully for possible hazards in your workarea. Examples of these hazards are moist floors,nongrounded power extension cables, power surges,and missing safety grounds.Do not touch live electrical circuits with the reflectivesurface of a plastic dental mirror. The surface isconductive; such touching can cause personal injury andmachine damage.Do not service the following parts with the power onwhen they are removed from their normal operatingplaces in a machine:– Power supply units– Pumps– Blowers and fans– Motor generatorsand similar units. (This practice ensures correctgrounding of the units.)v If an electrical accident occurs:– Use caution; do not become a victim yourself.– Switch off power.– Send another person to get medical aid.Safety inspection guideThe purpose of this inspection guide is to assist you inidentifying potentially unsafe conditions. As each machinewas designed and built, required safety items wereinstalled to protect users and service personnel from injury.This guide addresses only those items. You should usegood judgment to identify potential safety hazards due toattachment of non-IBM features or options not covered bythis inspection guide.If any unsafe conditions are present, you must determinehow serious the apparent hazard could be and whetheryou can continue without first correcting the problem.Consider these conditions and the safety hazards theypresent:v Electrical hazards, especially primary power (primaryvoltage on the frame can cause serious or fatalelectrical shock)v Explosive hazards, such as a damaged CRT face or abulging capacitorv Mechanical hazards, such as loose or missing hardware14ThinkPad TransNoteDownloaded from www.Manualslib.com manuals search engine

Safety informationTo determine whether there are any potentially unsafeconditions, use the following checklist at the beginning ofevery service task. Begin the checks with the power off,and the power cord disconnected.Checklist:1. Check exterior covers for damage (loose, broken, orsharp edges).2. Power-off the computer. Disconnect the power cord.3. Check the power cord for:a. A third-wire ground connector in good condition.Use a meter to measure third-wire groundcontinuity for 0.1 or less between the externalground pin and frame ground.b. The power cord should be the type specified in theparts list.c. Insulation must not be frayed or worn.4. Remove the cover.5. Check for any obvious non-IBM alterations. Use goodjudgment as to the safety of any non-IBM alterations.6. Check inside the unit for any obvious unsafeconditions, such as metal filings, contamination, wateror other liquids, or signs of fire or smoke damage.7. Check for worn, frayed, or pinched cables.8. Check that the power-supply cover fasteners (screwsor rivets) have not been removed or tampered with.Handling electrostaticdischarge-sensitive devicesAny computer part containing transistors or integratedcircuits (ICs) should be considered sensitive to electrostaticdischarge (ESD). ESD damage can occur when there is adifference in charge between objects. Protect against ESDdamage by equalizing the charge so that the machine, thepart, the work mat, and the person handling the part are allat the same charge.Notes1. Use product-specific ESD procedures when theyexceed the requirements noted here.2. Make sure that the ESD protective devices youuse have been certified (ISO 9000) as fullyeffective.When handling ESD-sensitive parts:v Keep the parts in protective packages until they areinserted into the product.v Avoid contact with other people.v Wear a grounded wrist strap against your skin toeliminate static on your body.IntroductionDownlo
