Safety warning notice
WARNING! To reduce the possibility of heat-related injuries or of overheating the device, do not
place the device directly on your lap or obstruct the device air vents. Use the device only on a hard,
flat surface. Do not allow another hard surface, such as an adjoining optional printer, or a soft
surface, such as pillows or rugs or clothing, to block airflow. Also, do not allow the AC adapter to
contact the skin or a soft surface, such as pillows or rugs or clothing, during operation. The device

4 Removal 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
●
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.
8 Chapter 4 Removal and replacement preliminary requirements
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.
CAUTION: A product can be degraded by as little as 700 V.
Typical electrostatic voltage levels
Relative humidity
Event 10% 40% 55%
Walking across carpet 35,000 V 15,000 V 7,500 V
Walking across vinyl floor 12,000 V 5,000 V 3,000 V
Motions of bench worker 6,000 V 800 V 400 V
Removing DIPS from plastic tube 2,000 V 700 V 400 V
Removing DIPS from vinyl tray 11,500 V 4,000 V 2,000 V
Removing DIPS from Styrofoam 14,500 V 5,000 V 3,500 V
Removing bubble pack from PCB 26,500 V 20,000 V 7,000 V
Packing PCBs in foam-lined box 21,000 V 11,000 V 5,000 V
Grounding guidelines 9
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.
●
10 Chapter 4 Removal and replacement preliminary requirements
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
●
The following table lists the shielding protection provided by antistatic bags and floor mats.
Material Use Voltage protection level
Antistatic plastics Bags 1,500 V
Carbon-loaded plastic Floor mats 7,500 V
Metallized laminate Floor mats 5,000 V
