Chapter 1. Read this first: Important safety informationThis chapter contains the safety information that you must be familiar with.Power cords and power adaptersUse only the power cords and power adapters supplied by the product manufacturer. Do not use the acpower cord for other devices.The power cords shall be safety approved. For Germany, it shall be H05VV-F, 3G, 0.75 mm2, or better. Forother countries, the suitable types shall be used accordingly.Never wrap a power cord around a power adapter or other object. Doing so can stress the cord in ways thatcan cause the cord to fray, crack, or crimp. This can present a safety hazard.Always route power cords so that they will not be walked on, tripped over, or pinched by objects.Protect power cord and power adapters from liquids. For instance, do not leave your power cord or poweradapter near sinks, tubs, toilets, or on floors that are cleaned with liquid cleansers. Liquids can cause ashort circuit, particularly if the power cord or power adapter has been stressed by misuse. Liquids also cancause gradual corrosion of power cord terminals and/or the connector terminals on a power adapter,which can eventually result in overheating.Ensure that all power cord connectors are securely and completely plugged into receptacles.Do not use any power adapter that shows corrosion at the ac input pins or shows signs of overheating (suchas deformed plastic) at the ac input or anywhere on the power adapter.Do not use any power cords where the electrical contacts on either end show signs of corrosion oroverheating or where the power cord appears to have been damaged in any way.General safetyFollow these rules to ensure general safety: Observe good housekeeping in the area of the machines during and after maintenance. When 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 themuscles in your back.Attention:Do not attempt to lift any objects that weigh more than 16 kg (35 lb) or objects that you think aretoo heavy for you. Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe. Before you start the machine, ensure that other service representatives and the customer's personnel arenot in a hazardous position. Copyright Lenovo 2015, 20161

Place removed covers and other parts in a safe place, away from all personnel, while you are servicingthe machine. Keep your tool case away from walk areas so that other people will not trip over it. Do not wear loose clothing that can be trapped in the moving parts of a machine. Ensure that your sleevesare fastened or rolled up above your elbows. If your hair is long, fasten it. Insert the ends of your necktie or scarf inside clothing or fasten it with a nonconductive clip, approximately8 centimeters (3 inches) from the end. Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing.Remember: Metal objects are good electrical conductors. Wear safety glasses when you are: hammering, drilling, soldering, cutting wire, attaching springs, usingsolvents, or working in any other conditions that might be hazardous to your eyes. After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety devicethat is worn or defective. Reinstall all covers correctly before returning the machine to the customer.CAUTION:Hazardous moving parts. Keep fingers and other body parts away.CAUTION:Before you open the computer cover, turn off the computer and wait several minutes until thecomputer is cool.Electrical safetyCAUTION:Electrical current from power, telephone, and communication cables can be hazardous. To avoidpersonal injury or equipment damage, disconnect the attached power cords, telecommunicationsystems, networks, and modems before you open the computer covers, unless instructed otherwisein the installation and configuration procedures.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 softmaterial that does not insulate you when working with live electrical currents. Many customers have, neartheir 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.2ThinkCentre M700 and M900 Hardware Maintenance Manual

Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electricalaccident 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 Field Replaceable Units (FRUs) Before you start to work on the machine, unplug the power cord. If you cannot unplug it, power off thewall box that supplies power to the machine and lock the wall box in the off position. If you need to work on a machine that has exposed electrical circuits, observe the following precautions:– Ensure that another person, familiar with the power-off controls, is near you.Remember: Another person must be there to switch off the power, if necessary.– Use only one hand when working with powered-on electrical equipment; keep the other hand in yourpocket or behind your back.Remember: There must be a complete circuit to cause electrical shock. By observing the above rule,you may prevent a current from passing through your body.– When using a tester, set the controls correctly and use the approved probe leads and accessories forthat tester.– Stand on suitable rubber mats (obtained locally, if necessary) to insulate you from grounds such asmetal floor strips and machine frames.Observe the special safety precautions when you work with very high voltages; these instructions are inthe safety sections of maintenance information. Use extreme care when measuring high voltages. Regularly inspect and maintain your electrical hand tools for safe operational condition. Do not use worn or broken tools and testers. Never assume that power has been disconnected from a circuit. First, check that it has been powered-off. Always look carefully for possible hazards in your work area. 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 reflective surface of a plastic dental mirror. The surface isconductive; such touching can cause personal injury and machine damage. Do not service the following parts with the power on when they are removed from their normal operatingplaces in a machine:– Power supply units– Pumps– Blowers and fans– Motor generatorsand similar units. (This practice ensures correct grounding of the units.) If an electrical accident occurs:– Use caution; do not become a victim yourself.– Switch off power.– Send another person to get medical aid.Chapter 1. Read this first: Important safety information3

Safety inspection guideThe intent of this inspection guide is to assist you in identifying potentially unsafe conditions on theseproducts. Each machine, as it was designed and built, had required safety items installed to protect usersand service personnel from injury. This guide addresses only those items. However, good judgment shouldbe used to identify potential safety hazards due to attachment of features or options not covered by thisinspection guide.If any unsafe conditions are present, you must determine how serious the apparent hazard could be andwhether you can continue without first correcting the problem.Consider these conditions and the safety hazards they present: Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatalelectrical shock). Explosive hazards, such as a damaged CRT face or bulging capacitor Mechanical hazards, such as loose or missing hardwareThe guide consists of a series of steps presented in a checklist. Begin the checks with the power off, andthe power cord disconnected.Checklist:1. Check exterior covers for damage (loose, broken, or sharp 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 ohm or less between the external ground pin and frame ground.b. The power cord should be the appropriate type as specified in the parts listings.c. Insulation must not be frayed or worn.4. Remove the cover.5. Check for any obvious alterations. Use good judgment as to the safety of any alterations.6. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water orother liquids, or signs of fire or smoke damage.7. Check for worn, frayed, or pinched cables.8. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.Handling electrostatic discharge-sensitive devicesAny computer part containing transistors or integrated circuits (ICs) should be considered sensitive toelectrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects.To protect against ESD damage, equalize the charge between objects. Then, the machine, the part, thework mat, and the person handling the part are all at the same charge.Notes:1. Use product-specific ESD procedures when they exceed the requirements noted here.2. Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective.When handling ESD-sensitive parts: Keep the parts in protective packages until they are inserted into the product. Avoid contact with other people while handling the part.4ThinkCentre M700 and M900 Hardware Maintenance Manual

Wear a grounded wrist strap against your skin to eliminate static on your body. Prevent the part from touching your clothing. Most clothing is insulative and retains a charge evenwhen you are wearing a wrist strap. Use the black side of a grounded work mat to provide a static-free work surface. The mat is especiallyuseful when handling ESD-sensitive devices. Select a grounding system, such as those listed below, to provide protection that meets the specificservice requirement.Note: The use of a grounding system is desirable but not required to protect against ESD damage.– Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground.– Use an ESD common ground or reference point when working on a double-insulated orbattery-operated system. 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 requirementsElectrical grounding of the computer is required for operator safety and correct system function. Propergrounding of the electrical outlet can be verified by a certified electrician.Safety notices (multi-lingual translations)The caution and danger safety notices in this section are provided in the following languages: English Arabic Brazilian/Portuguese Chinese (simplified) Chinese (traditional) French German Hebrew Italian Korean SpanishDANGERElectrical current from power, telephone and communication cables is hazardous.To avoid a shock hazard: Do not connect or disconnect any cables or perform installation, maintenance, or reconfigurationof this product during an electrical storm.
