●Flat-bladed screwdriver
●Magnetic screwdriver
●Phillips P0 and P1 screwdrivers
Service considerations
The following sections include some of the considerations that you must keep in mind during
disassembly and assembly procedures.
NOTE:As you remove each subassembly from the computer, place the subassembly (and all
accompanying...

Cables and connectors
CAUTION:When servicing the computer, be sure that 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 avoid damage. Apply only the tension required to unseat
or seat the cables during removal and insertion. Handle 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
they...

Grounding guidelines
Electrostatic discharge damage
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, ESD contains enough power to alter device parameters or melt silicon junctions.
A discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or
microcircuitry. Even if the spark is...

Packaging and transporting guidelines
Follow 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 conductive or approved containers or packaging.
●Keep ESD-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...

Equipment guidelines
Grounding equipment must include either a wrist strap or a foot strap at a grounded workstation.
●When seated, wear a wrist strap connected to a grounded 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 times. On grounded mats with banana-plug connectors,
use alligator clips to connect a wrist strap.
●When standing, use foot straps and a grounded floor mat....

Unknown user password
If the computer you are servicing has an unknown user password, follow these steps to clear the
password.
NOTE:These steps also clear CMOS.
Before disassembling the computer, follow these steps:
1.Shut down the computer. If you are unsure whether the computer is off or in Hibernation, turn the
computer on, and then shut it down through the operating system.
2.Disconnect all external devices connected to the computer.
3.Disconnect the power from the computer by first unplugging the...
