and assembly procedures.
NOTE: As you remove each subassembly from the computer, place the subassembly (and all...

Cables and connectors
CAUTION:When servicing the computer, be sure th at cables are placed in their proper
locations during the reassembly process. Improper cable placement can damage the computer.
Cables must be handled with extreme care to avoi d damage. Apply only the tension required to unseat
or seat the cables during removal and insertion. Ha ndle cables by the connector whenever possible. In
all cases, avoid bending, twisting,  or tearing cables. Be sure that cables are routed in such a way that...

Grounding guidelines
Electrostatic discharge damage
Electronic components are sensitiv e to electrostatic discharge (ESD). Circuitry design and structure
determine the degree of sens itivity. Networks built into many integr ated circuits provide some protection,
but in many cases, ESD contains enough power to  alter device parameters or melt silicon junctions.
A discharge of static electricity fr om a finger or other conductor can destroy static-sensitive devices or
microcircuitry. Even if the spark is...

Packaging and transporting guidelinesFollow these grounding guidelines when  packaging and transporting equipment:
● To avoid hand contact, transport products
 in static-safe tubes, bags, or boxes.
● Protect ESD-sensitive parts and assemblies with co
nductive or approved containers or packaging.
● Keep ESD-sensitive parts in their containers unti
l the parts arrive at static-free workstations.
● Place items on a grounded surface before
 removing items from their containers.
● Always be properly grounded...

Equipment guidelinesGrounding equipment must include either a wrist st rap or a foot strap at a grounded workstation.
● When seated, wear a wrist strap connected to a gr
ounded system. Wrist straps are flexible straps
with a minimum of one megohm ±10% resistance in  the ground cords. To provide proper ground,
wear a strap snugly against the skin at all time s. On grounded mats with banana-plug connectors,
use alligator clips to  connect a wrist strap.
● When standing, use foot straps and a grounded...
