The following section presents safety information with which you need to be familiar before you service a ThinkPad computer. Make sure that 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 object that weighs more than 16 kg 35 lb or that you think is 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. Do not obstruct fan louvers or cover them with labels or stickers. Handling the cord on this product or cords associated with accessories sold with this product will expose you to lead, a chemical known to the State of California to cause cancer, and birth defects or other reproductive harm. Wash hands after handling.

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; Instructions for these precautions 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-ThinkPad 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. 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. 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-ThinkPad alterations. Use good judgment as to the safety of any non-ThinkPad 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 to guard against ESD damage is desirable but not necessary. 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.

Such devices are also sold separately as options. If one of these drives is installed, it is certified in the U. Use of controls or adjustments or performance of procedures other than those specified herein might result in hazardous radiation exposure. There are no serviceable parts inside those drives.
