[. . . ] Place items on a grounded surface before removing items from their containers. Always be properly grounded when touching a sensitive component or assembly. Store reusable electrostatic-sensitive parts from assemblies in protective packaging or nonconductive foam. Use transporters and conveyors made of antistatic belts and roller bushings. Ensure that mechanized equipment used for moving materials is wired to ground and that proper materials are selected to avoid static charging. When grounding is not possible, use an ionizer to dissipate electric charges. 4­4 Maintenance and Service Guide Removal and Replacement Preliminaries 4. 6 Workstation Precautions Use the following grounding precautions at workstations: Cover the workstation with approved static-shielding material (refer to Table 4-2, "Static-Shielding Materials"). Use a wrist strap connected to a properly grounded work surface and use properly grounded tools and equipment. Use conductive field service tools, such as cutters, screwdrivers, and vacuums. When using fixtures that must directly contact dissipative surfaces, only use fixtures made of static-safe materials. Keep the work area free of nonconductive materials, such as ordinary plastic assembly aids and Styrofoam. Handle electrostatic-sensitive components, parts, and assemblies by the case or PCM laminate. Turn off power and input signals before inserting or removing connectors or test equipment. Maintenance and Service Guide 4­5 Removal and Replacement Preliminaries 4. 7 Grounding Equipment and Methods Grounding equipment must include either a wrist strap or a foot strap at a grounded workstation. Wrist straps are flexible straps with a minimum of one megohm ±10% resistance in the ground cords. To provide proper ground, wear a strap snugly against the skin at all times. On grounded mats with banana-plug connectors, use alligator clips to connect a wrist strap. Foot straps (heel, toe, or boot straps) can be used at standing workstations and are compatible with most types of shoes or boots. On conductive floors or dissipative floor mats, use foot straps on both feet with a minimum of one megohm resistance between the operator and ground. To be effective, the conductive strips must be worn in contact with the skin. 4­6 Maintenance and Service Guide Removal and Replacement Preliminaries Other grounding equipment recommended for use in preventing electrostatic damage includes: Antistatic tape Antistatic smocks, aprons, and sleeve protectors Conductive bins and other assembly or soldering aids Nonconductive foam Conductive tabletop workstations with ground cords of one megohm resistance Static-dissipative tables or floor mats with hard ties to the ground Field service kits Static awareness labels Material-handling packages Nonconductive plastic bags, tubes, or boxes Metal tote boxes Electrostatic voltage levels and protective materials Maintenance and Service Guide 4­7 Removal and Replacement Preliminaries Table 4-1 shows how humidity affects the electrostatic voltage levels generated by different activities.

There are as many as 54 screws, in 8 different sizes and types, that may need to be removed, replaced, or loosened when servicing the notebook. Make special note of each screw size and location during removal and replacement. Refer to Appendix C, "Screw Listing, " for detailed information on screw sizes, locations, and usage.

[. . . ] The wall plug must be a two-pole grounding type with a NEMA 5-15P (15 A, 125 V) or NEMA 6-15P (15 A, 250 V) configuration. The appliance coupler, flexible cord, and wall plug must bear a "T" mark and registration number in accordance with the Japanese Dentori Law. The flexible cord must be Type VCT or VCTF, 3-conductor, 1. 00 mm² conductor size. The wall plug must be a two-pole grounding type with a Japanese Industrial Standard C8303 (7 A, 125 V) configuration. [. . . ]
