							4Removal and replacement preliminary requirements
Tools required
You will need the following tools to complete the removal and replacement procedures:
●Magnetic screw driver
●Phillips P0 screw driver
●Plastic case utility tool
●Torx T5 screw driver
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 tablet, place the subassembly (and all 
accompanying screws) away from the work area to prevent damage.
Plastic parts
CAUTION:Using excessive force during disassembly and reassembly can damage plastic parts. 
Use care when handling the plastic parts. Apply pressure only at the points designated in the 
maintenance instructions.
Cables and connectors
CAUTION:When servicing the tablet, be sure that cables are placed in their proper locations during 
the reassembly process. Improper cable placement can damage the tablet.
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 cannot be caught or snagged by parts being removed or replaced. Handle flex 
cables with extreme care; these cables tear easily.

							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 neither felt nor heard, damage may have occurred.
An electronic device exposed to ESD may not be affected at all and can work perfectly throughout a 
normal cycle. Or the device may function normally for a while, then degrade in the internal layers, 
reducing its life expectancy.
CAUTION:To prevent damage to the tablet when you are removing or installing internal 
components, observe these precautions:
Keep components in their electrostatic-safe containers until you are ready to install them.
Before touching an electronic component, discharge static electricity by using the guidelines 
described in this section.
Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.
If you remove a component, place it in an electrostatic-safe container.
The following table shows how humidity affects the electrostatic voltage levels generated by 
different activities.

							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 touching a component or assembly.
●Store reusable ESD-sensitive parts from assemblies in protective packaging or 
nonconductive foam.
●Use transporters and conveyors made of antistatic belts and roller bushings. Be sure 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.
Workstation guidelines
Follow these grounding workstation guidelines:
●Cover the workstation with approved static-shielding material.
●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, screw drivers, and vacuums.
●When fixtures must directly contact dissipative surfaces, use fixtures made only of static-
safe materials.
●Keep the work area free of nonconductive materials, such as ordinary plastic assembly aids  and Styrofoam.
●Handle ESD-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.
Grounding guidelines9 
						

							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. Foot straps (heel, toe, or boot straps) 
can be used at standing workstations and are compatible with most types of shoes or boots. On 
conductive floors or dissipative floor mats, use foot straps on both feet with a minimum of one 
megohm resistance between the operator and ground. To be effective, the conductive must be 
worn in contact with the skin.
The following grounding equipment is recommended to prevent electrostatic damage:
●Antistatic tape
●Antistatic smocks, aprons, and sleeve protectors
●Conductive bins and other assembly or soldering aids
●Nonconductive foam
●Conductive tabletop workstations with ground cords of one megohm resistance
●Static-dissipative tables or floor mats with hard ties to the ground
●Field service kits
●Static awareness labels
●Material-handling packages
●Nonconductive plastic bags, tubes, or boxes
●Metal tote boxes
●Electrostatic voltage levels and protective materials
