    							  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:
    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 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.
    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 customers personnel
    are not in a hazardous position.
    Place removed covers and other parts in a safe
    place, away from all personnel, while you are
    servicing the 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 sleeves
    are 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, approximately 8
    centimeters (3 inches) from the end.
    Do not wear jewelry, chains, metal-frame eyeglasses,
    or metal fasteners for your clothing.
    Attention:Metal objects are good electrical
    conductors.
    Wear 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.
    After service, reinstall all safety shields, guards,
    labels, and ground wires. Replace any safety device
    that is worn or defective.
    Reinstall all covers correctly before returning the
    machine to the customer.
       Introduction
     11 
    						
    							  Electrical Safety
    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 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.
    Find the room emergency power-off (EPO) switch,
    disconnecting switch, or electrical outlet. If an
    electrical accident 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 main units
    Before you start to work on the machine, unplug the
    power cord. 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.
    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.
    Attention: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 your pocket or behind your back.
    Attention: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 testers, set the controls correctly
    and use the approved probe leads and
    accessories for that tester.
    –Stand on suitable rubber mats (obtained locally,
    if necessary) to insulate you from grounds such
    as metal floor strips and machine frames.
    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.
    12ThinkPad 570 and 570E Hardware Maintenance
    Manual   
    						
    							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 is
    conductive; 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 operating
    places in a machine:
    –Power supply units
     –Pumps
    –Blowers and fans
     –Motor generators
    and 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.
    Safety Inspection Guide
    The intent of this inspection guide is to assist you in
    identifying potentially unsafe conditions on these products.
    Each machine, as it was designed and built, had required
    safety items installed to protect users and service
    personnel from injury. This guide addresses only those
    items. However, good judgment should be used 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.
    Consider these conditions and the safety hazards they
    present:
    Electrical hazards, especially primary power (primary
    voltage on the frame can cause serious or fatal
    electrical shock).
    Explosive hazards, such as a damaged CRT face or
    bulging capacitor
    Mechanical hazards, such as loose or missing
    hardware
       Introduction
     13 
    						
    							The guide consists of a series of steps presented in a
    checklist. Begin the checks with the power off, and the
    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 ground
    continuity 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 non-IBM alterations. Use
    good judgment as to the safety of any non-IBM
    alterations.
    6. 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.
    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 Devices
    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.
     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.
    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 even when
    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 especially
    useful when handling ESD-sensitive devices.
    Select a grounding system, such as those listed
    below, to provide protection that meets the specific
    service 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 or
    battery-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 Requirements
    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.
