4 Removal and replacement procedures Preliminary replacement requirements Tools required You will need the following tools to complete the removal and replacement procedures: ● Flat-bladed screwdriver ● Magnetic screwdriver ● Phillips P0 and P1 screwdrivers Service considerations The following sections include some of the considerations that you must keep in mind during disassembly and assembly procedures.
Drive handling CAUTION: Drives are fragile components that must be handled with care. To prevent damage to the computer, damage to a drive, or loss of information, observe these precautions: Before removing or inserting a hard drive, shut down the computer. If you are unsure whether the computer is off or in Hibernation, turn the computer on, and then shut it down through the operating system. Before handling a drive, be sure that you are discharged of static electricity.
CAUTION: A product can be degraded by as little as 700 V.
Packaging and transporting guidelines Follow these grounding guidelines when packaging and transporting equipment: ● To avoid hand contact, transport products in static-safe tubes, bags, or boxes. ● Protect ESD-sensitive parts and assemblies with conductive or approved containers or packaging. ● Keep ESD-sensitive parts in their containers until the parts arrive at static-free workstations. ● Place items on a grounded surface before removing items from their containers.
Equipment guidelines 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. 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.
