Removal and Replacement Preliminaries 4.2 Service Considerations The following sections include some of the considerations that you should keep in mind during disassembly and assembly procedures. ✎ As you remove each subassembly from the computer, place the subassembly (and all accompanying screws) away from the work area to prevent damage.
Page 63: Preventing Damage To Removable Drives
4.3 Preventing Damage to Removable Drives Removable drives are fragile components that must be handled with care. To prevent damage to the computer, damage to a removable drive, or loss of information, observe the following precautions: Before removing or inserting a hard drive, shut down the computer.
Page 64: Preventing Electrostatic Damage
Removal and Replacement Preliminaries 4.4 Preventing Electrostatic Damage Many electronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structure determine the degree of sensitivity. Networks built into many integrated circuits provide some protection, but in many cases the discharge contains enough power to alter device parameters or melt silicon junctions.
Page 65: Workstation Precautions
Place reusable electrostatic-sensitive parts from assemblies in protective packaging or nonconductive foam. Use transporters and conveyers 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.
Page 66: Grounding Equipment And Methods
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. When seated, wear a wrist strap connected to a grounded system. Wrist straps are flexible straps with a minimum of one megohm ±10% resistance in the ground cords.
