Product Description

The HP Pavilion dv1000 Notebook PC 1 and the HP Compaq nx4800 Notebook PC and the Compaq Presario V2000 Notebook PC (both represented by 2) offer advanced modularity, Intel Pentium M and Celeron M processors, and extensive multimedia support.
HP Pavilion dv1000, HP Compaq nx4800, and Compaq Presario V2000

1.1 Features

Exhaust vents (4)

To prevent overheating, do not obstruct vents. Do not allow a hard surface, such as a printer, or a soft surface, such as pillows, thick rugs or clothing, to block airflow.
Hard drive bay Mini PCI compartment
Holds the internal hard drive. Holds an optional wireless LAN device.
To prevent an unresponsive system and the display of a warning message, install only a Mini PCI device authorized for use in the computer by the governmental agency that regulates wireless devices in your country. If you install a device and then receive a warning message, remove the device to restore computer functionality. Then contact Customer Care.
Memory module compartment
Contains two memory slots that support replaceable memory modules. The number of preinstalled memory modules varies by computer model. Contain the computer serial number and other applicable regulatory labels.

1.5 Design Overview

This section presents a design overview of key parts and features of the computer. Refer to Chapter 3, Illustrated Parts Catalog, to identify replacement parts, and Chapter 5, Removal and Replacement Procedures, for disassembly steps. The system board provides the following device connections:
Memory module Mini PCI communications devices Hard drive Display Keyboard and TouchPad Audio Intel Pentium M and Celeron M processors Fan PC Card
CAUTION: To properly ventilate the computer, allow at least a 7.6-cm (3-inch) clearance on the left and right sides of the computer.
The computer uses an electric fan for ventilation. The fan is controlled by a temperature sensor and is designed to be turned on automatically when high temperature conditions exist. These conditions are affected by high external temperatures, system power consumption, power management/battery conservation configurations, battery fast charging, and software applications. Exhaust air is displaced through the ventilation grill located on the left side of the computer.

Troubleshooting

WARNING: Only authorized technicians trained by HP should repair this equipment. All troubleshooting and repair procedures are detailed to allow only subassembly-/module-level repair. Because of the complexity of the individual boards and subassemblies, do not attempt to make repairs at the component level or modifications to any printed wiring board. Improper repairs can create a safety hazard. Any indication of component replacement or printed wiring board modification may void any warranty or exchange allowances.

4.4 Preventing Electrostatic Damage
Many electronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structure determine the degree of sensitivity. Networks built into many integrated circuits provide some protection, but in many cases, the discharge contains enough power to alter device parameters or melt silicon junctions. A sudden discharge of static electricity from a 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 might not be affected at all and can work perfectly throughout a normal cycle. Or the device might function normally for a while, then degrade in the internal layers, reducing its life expectancy.
4.5 Packaging and Transporting Precautions
Use the following grounding precautions when packaging and transporting equipment: To avoid hand contact, transport products in static-safe containers, such as tubes, bags, or boxes. Protect all electrostatic-sensitive parts and assemblies with conductive or approved containers or packaging. Keep electrostatic-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. Always be properly grounded when touching a sensitive component or assembly. Store reusable electrostatic-sensitive parts from assemblies in protective packaging or nonconductive foam. Use transporters and conveyors made of antistatic belts and roller bushings. Ensure that mechanized equipment used for moving materials is wired to ground and that proper materials are selected to avoid static charging. When grounding is not possible, use an ionizer to dissipate electric charges.
4.6 Workstation Precautions
Use the following grounding precautions at workstations: Cover the workstation with approved static-shielding material (refer to Table 4-2, Static-Shielding Materials). Use a wrist strap connected to a properly grounded work surface and use properly grounded tools and equipment. Use conductive field service tools, such as cutters, screwdrivers, and vacuums. When using fixtures that must directly contact dissipative surfaces, only use fixtures made of static-safe materials. Keep the work area free of nonconductive materials, such as ordinary plastic assembly aids and Styrofoam. Handle electrostatic-sensitive components, parts, and assemblies by the case or PCM laminate. Handle these items only at static-free workstations. Avoid contact with pins, leads, or circuitry. Turn off power and input signals before inserting or removing connectors or test equipment.

Removal and Replacement Procedures
This chapter provides removal and replacement procedures. There are as many as 58 screws, in 7 different sizes and types, that may need to be removed, replaced, or loosened when servicing the computer. Make special note of each screw size and location during removal and replacement. Refer to Appendix C, Screw Listing, for detailed information on screw sizes, locations, and usage.
