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. CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system board.
Generating static The following table shows that: ● Different activities generate different amounts of static electricity. ● Static electricity increases as humidity decreases. Relative Humidity Event Walking across carpet 7,500 V 15,000 V 35,000 V Walking across vinyl floor 3,000 V 5,000 V 12,000 V Motions of bench worker...
Personal grounding methods and equipment Use the following equipment to prevent static electricity damage to equipment: ● Wrist straps are flexible straps with a maximum of one-megohm ± 10% resistance in the ground cords. To provide proper ground, a strap must be worn snug against bare skin. The ground cord must be connected and fit snugly into the banana plug connector on the grounding mat or workstation.
● Material handling packages Conductive plastic bags ● ● Conductive plastic tubes Conductive tote boxes ● ● Opaque shielding bags Transparent metallized shielding bags ● ● Transparent shielding tubes Operating guidelines To prevent overheating and to help prolong the life of the computer: Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold.
Cleaning the Computer Case Follow all safety precautions in General cleaning safety precautions on page 17 before cleaning the computer. To clean the computer case, follow the procedures described below: ● To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab. For stronger stains, use a mild dishwashing liquid diluted with water.
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.
Batteries, battery packs, and accumulators should not be disposed of together with the general household waste. In order to forward them to recycling or proper disposal, please use the public collection system or return them to HP, their authorized partners, or their agents. Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation...
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.
