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: v Observe good housekeeping in the area of the machines during and after maintenance.
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.
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. v Regularly inspect and maintain your electrical hand tools for safe operational condition.
v Mechanical hazards, such as loose or missing hardware T o 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.
v Wear a grounded wrist strap against your skin to eliminate static on your body . v Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when you are wearing a wrist strap. v Use the black side of a grounded work mat to provide a static-free work surface.
When a CD-ROM drive, DVD drive or the other laser product is installed, note the following: CAUTION: Use of controls or adjustments or performance of procedures other than those specified herein might result in hazardous radiation exposure.
Opening the CD-ROM drive, DVD-ROM drive or the other optical storage device could result in exposure to hazardous laser radiation. There are no serviceable parts inside those drives. Do not open. Some CD-ROM drives, DVD-ROM drives or the other optical storage devices contain an embedded Class 3A or Class 3B laser diode.
DANGER Emits visible and invisible laser radiation when open. Do not stare into the beam, do not view directly with optical instruments, and avoid direct exposure to the beam.
