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:
vObserve good housekeeping in the area of the
machines during and after maintenance.
vWhen 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...

Electrical safety
Observe the following rules when working on electrical
equipment.
ImportantUse 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.
vFind the room emergency power-off...

safety sections of maintenance information. Use
extreme care when measuring high voltages.
vRegularly inspect and maintain your electrical hand tools
for safe operational condition.
vDo not use worn or broken tools and testers.
vNever assumethat power has been disconnected from
a circuit. First,checkthat it has been powered off.
vAlways 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...

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.
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...

vPrevent the part from touching your clothing. Most
clothing is insulative and retains a charge even when
you are wearing a wrist strap.
vUse 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.
vSelect a grounding system, such as those listed below,
to provide protection that meets the specific service
requirement.
NoteThe use of a grounding system is desirable but
not required to protect against ESD damage....
