CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system board.

  • Page 20: Preventing Electrostatic Damage To Equipment

    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. Protect all electrostatic parts and assemblies with conductive or approved containers or packaging.

  • Page 21: Recommended Materials And Equipment

    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 one-megohm +/- 10% resistance ●...

  • Page 23: Cleaning The Monitor

    ● If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool is available through many electronic supply outlets. CAUTION: 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.

  • Page 24: Screws

    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.

  • Page 25: Sata Hard Drives

    6.0 Gb/s 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.

  • Page 26: Cable Management

    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 designed to take excessive pressure on them.
