Chapter 1. Illustrated Parts Catalog Chapter 1.0 Introduction Chapter 1.1 Illustrated Parts Breakdown: Compaq Contura Aero Family Of Personal Computers The Compaq Contura Aero Family of Personal Computers joins a display assembly and system unit together with a clutch secured by screws in the chassis, display enclosure, and a display pin allowing it to open and close. The display assembly is secured by screws installed in the front of the display enclosure.
o o o o PCMCIA ejector rails Trackball assembly Memory expansion board (optional) System board The keyboard is secured to the system unit with four screws and a hook latch in the front. Once the screws are removed, the keyboard must be rotated from the rear forward to disengage it from the hook latch. The keyboard must be removed to allow access to any of the system board components. The keyboard is connected to the system board with two ribbon cables and zero insertion force (ZIF) connectors.

Chapter 2. Service Preliminaries Chapter 2.0 Introduction This chapter provides general service information for the computer and the base unit. Adherence to the procedures and precautions described in this chapter is essential for proper service. Chapter 2.1 Electrostatic Discharge (International) A sudden discharge of static electricity from a finger or other conductor can destroy static sensitive devices or micro circuitry. Often the spark is neither felt or heard, but damage occurs.
structure determine the degree of sensitivity. The following proper packaging and grounding precautions are necessary to prevent damage: o Protect all electrostatic parts and assemblies with conductive or approved containers or packaging. o Keep electrostatic sensitive parts in their containers until they arrive at static free stations. o Place items on a grounded surface before removing them from their container. o Always be properly grounded when touching a sensitive component or assembly.
To prevent static damage at the workstation, use the following precautions: o Cover the workstation with approved static dissipative material. Provide a wrist strap connected to the work surface and properly grounded tools and equipment. o Use static dissipative mats, heel straps, or air ionizers to give added protection. o Handle electrostatic sensitive components, parts, and assemblies by the case or PCB laminate. Handle them only at static free workstations.
o Conductive bins, and other assembly or soldering aids o Conductive foam o Conductive table top workstations with ground cord of 1 megohm of resistance o Static dissipative table or floor mats with hard tie to ground o Field service kits o Static awareness labels o Wrist straps and footwear straps providing 1 megohm +/- 10% resistance o Material handling packages o Conductive plastic bags o Conductive plastic tubes o Conductive tote boxes o Metal tote boxes o Opaque shielding bags o Transparent metallized
Screws The screws used in these products are not interchangeable. If an incorrect screw is used during the reassembly process, it could cause damage to the unit. Compaq strongly recommends that all screws removed during the disassembly process be kept with the part that was removed, then returned to their proper locations. IMPORTANT: As each subassembly is removed from the computer, it should be placed away from the work area to prevent damage.
Plastics The plastics used can be damaged by application of excessive force during disassembly and reassembly. When handling the plastic cases and housing assemblies, use care. Do not use screwdrivers or similar tools to pry apart plastics. Where necessary, use the Case utility tool (spare part number 119070-001). Proper handling of this tool is illustrated in the disassembly and reassembly procedures. Disposal of a Used Battery Battery components are considered environmentally harmful.
A sudden discharge of static electricity from a finger or other conductor can destroy static sensitive devices or micro circuitry. Often the spark is neither felt or heard, but damage occurs. An electronic device exposed to electrostatic discharge (ESD) may not be affected at all and will work perfectly throughout a normal cycle. Or it may function normally for a while, then degrade in the internal layers, reducing its life expectancy.
o Place reusable electronic sensitive parts from assemblies in protective packaging or conductive foam. Use transporters and conveyors made of antistatic belts and metal roller bushings. Mechanized equipment used for moving materials must be wired to ground and proper materials selected to avoid static charging. When grounding is not possible, use an ionizer to dissipate electric charges.
o Turn off power and input signals before inserting and removing connectors or test equipment. o Use fixtures made of static safe materials when fixtures must directly contact dissipative surfaces. o Keep work area free of nonconductive materials such as ordinary plastic assembly aids and Styrofoam. o Use field service tools, such as cutters, screwdrivers, vacuums, that are conductive. o Use a portable field service kit with a static dissipative vinyl pouch that folds out of a work mat.
o Material handling packages o Conductive plastic bags o Conductive plastic tubes o Conductive tote boxes o Metal tote boxes o Opaque shielding bags o Transparent metallized shielding bags o Transparent shielding tubes SERVICE CONSIDERATIONS Listed below are some of the considerations that should be kept in mind during the disassembly and assembly of the computer.
Cables and Connectors Most cables used throughout the unit are flex cables (Figures 2-1, 2-2, 2-3). These cables must be handled with extreme care to avoid damage. Apply only the tension required to seat or unseat the cables during insertion or removal from the connector. Handle cables by the connector or pull tabs whenever possible.
Plastics The plastics used can be damaged by application of excessive force during disassembly and reassembly. When handling the plastic cases and housing assemblies, use care. Do not use screwdrivers or similar tools to pry apart plastics. Where necessary, use the Case utility tool (spare part number 119070-001). Proper handling of this tool is illustrated in the disassembly and reassembly procedures. Disposal of a Used Battery Battery components are considered environmentally harmful.
In the interest of our customers and the protection of our environment, Compaq has initiated a disposal/recycling program for these battery packs. Further, because Compaq is funding all costs associated with the program, it is offered at no cost to the Compaq laptop and notebook customer. IMPORTANT: Toll Free Number (U.S) 1-800-524-9859, (Canada) 1-800-263-5868 Customers in North America can take advantage of this program immediately.
