5 Identifying the Chassis, Routine Care, 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. You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.
Electrostatic Discharge Information A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device exposed to electrostatic discharge (ESD) may not appear to be affected at all and can work perfectly throughout a normal cycle. The device may function normally for a while, but it has been degraded in the internal layers, reducing its life expectancy.
● Always be properly grounded when touching a sensitive component or assembly. ● Avoid contact with pins, leads, or circuitry. ● Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive foam. 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.
● Conductive bins and other assembly or soldering aids ● Conductive foam ● Conductive tabletop workstations with ground cord of one-megohm +/- 10% resistance ● Static-dissipative table or floor mats with hard tie to ground ● Field service kits ● Static awareness labels ● Wrist straps and footwear straps providing one-megohm +/- 10% resistance ● Material handling packages ● Conductive plastic bags ● Conductive plastic tubes ● Conductive tote boxes ● Opaque shielding bags ● Transparen
● Never cover the ventilation slots on the monitor with any type of material. ● Install or enable power management functions of the operating system or other software, including sleep states. Routine Care General Cleaning Safety Precautions 1. Never use solvents or flammable solutions to clean the computer. 2. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and then use the cloth on the component. 3.
CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the keys. ● Visible debris underneath or between the keys may be removed by vacuuming or shaking. ● Canned, pressurized air may be used to clean debris from under the keys. Caution should be used as too much air pressure can dislodge lubricants applied under the wide keys. ● If you remove a key, use a specially designed key puller to prevent damage to the keys.
Tools and Software Requirements To service the computer, you need the following: ● Torx T-15 screwdriver (HP screwdriver with bits, PN 161946-001) ● Torx T-15 screwdriver with small diameter shank (for certain front bezel removal) ● Flat-bladed screwdriver (may sometimes be used in place of the Torx screwdriver) ● Phillips #2 screwdriver ● Diagnostics software ● HP tamper-resistant T-15 wrench (Smart Cover FailSafe Key, PN 166527-001) or HP tamperresistant bits (Smart Cover FailSafe Key, PN 16652
● Before handling a drive, ensure that you are discharged of static electricity. While handling a drive, avoid touching the connector. For more information about preventing electrostatic damage, refer to Electrostatic Discharge Information on page 20 ● Do not use excessive force when inserting a drive. ● Avoid exposing a hard drive to liquids, temperature extremes, or products that have magnetic fields such as monitors or speakers.
