Often the spark is n\ either felt nor 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. Although, it may function normally \ for a while, then degrade in the internal layers, reducing its life expectancy\ . Networks built into many integrated circuits provide some protection, bu\ t in many cases, the discharge contains enough power to alter device paramete\ rs or melt silicon junctions. Generating Static The table shows how different activities generate static electricity and\ at different electrostatic voltage levels.

Tool and Software Requirements To service the computer, you need the following: l Compaq screwdriver kit (Spare Part No. 161946-001) l Torx T-9 screwdriver l 3/16-inch and 5mm nut drivers (for screwlocks and standoffs) l Small, standard screwdriver l Small, Phillips screwdriver l Diagnostics software Screws The screws used in the computer are not interchangeable. If an incorrect\ screw is used during the reassembly process, it can damage the unit. Com\ paq strongly recommends that all screws removed during disassembly 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.

Cables must be h\ andled with extreme care to avoid damage. Apply only the tension required to seat or unseat the c\ ables during insertion or removal from the connector. Handle cables by the connector whenever poss\ ible. In all cases, avoid bending, twisting, or tearing the cables, and ensure that the cables are\ routed in such a way that they cannot be caught or snagged by parts being removed or replaced. Cables Use the following precautions when handling cables to avoid damage to th\ e cable or computer: l Always handle cables by their connectors. l Avoid bending, twisting, or pulling on the cables. l Apply minimum required force when seating or unseating the cables from t\ heir connectors. l Place the cables in such a manner that they cannot be caught or snagged \ by parts being removed or replaced. l Handle flex cables with extreme care; they can tear easily. CAUTION: When servicing these computers, ensure that cables are placed in their proper location during the reassembly process. Improper cable placement \ can cause severe damage to the unit.
