Routine care, SATA drive guidelines, and disassembly preparation This chapter provides general service information for the computer. Adherence to the procedures and precautions described in this chapter is essential for proper service. IMPORTANT: When the computer is plugged into an AC power source, voltage is always applied to the system board.
Preventing electrostatic damage to equipment Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of sensitivity. The following packaging and grounding precautions are necessary to prevent damage to electric components and accessories. ● To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes. ●...
Recommended materials and equipment Materials and equipment that are recommended for use in preventing static electricity include: Antistatic tape ● Antistatic smocks, aprons, or sleeve protectors ● Conductive bins and other assembly or soldering aids ● Conductive foam ● Conductive tabletop workstations with ground cord of 1 MΩ +/- 10% resistance ●...
Routine care General cleaning safety precautions Never use solvents or flammable solutions to clean the computer. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and then use the cloth on the component. Always unplug the computer when cleaning with liquids or damp cloths.
IMPORTANT: Never remove a wide leveled key (like the space bar) from the keyboard. If these keys are improperly removed or installed, the keyboard may not function properly. Cleaning under a key may be done with a swab moistened with isopropyl alcohol and squeezed out. Be ●...
The screws used in the computer are not interchangeable. They may have standard or metric threads and may be of different lengths. If an incorrect screw is used during the reassembly process, it can damage the unit. HP strongly recommends that all screws removed during disassembly be kept with the part that was removed, then returned to their proper locations.
SATA hard drive cables SATA data cable Always use an HP approved SATA 6.0 Gb/s cable as it is fully backwards compatible with the SATA 1.5 Gb/s drives. Current HP desktop products ship with SATA 6.0 Gb/s hard drives. SATA data cables are susceptible to damage if overflexed. Never crease a SATA data cable and never bend it tighter than a 30 mm (1.18 in) radius.
Cable management Always follow good cable management practices when working inside the computer. Keep cables away from major heat sources like the heat sink. ● Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like these are not ●...
Removal and replacement procedures Adherence to the procedures and precautions described in this chapter is essential for proper service.
