Removal and Replacement
Preliminaries
This chapter provides essential information for proper and safe 
removal and replacement service.
4.1 Tools Required
You will need the following tools to complete the removal and 
replacement procedures:
■Magnetic screwdriver
■Phillips P0 screwdriver
■7.0-mm socket wrench (for Evo Notebook N600c models)
■Tool kit (includes connector removal tool, loopback plugs, 
and case utility tool)

Plastic Parts
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
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...

4.3 Preventing Damage to 
Removable Drives
Removable drives are fragile components that must be handled 
with care. To prevent damage to the computer, damage to a 
removable drive, or loss of information, observe the following 
precautions:
■Before removing or inserting a hard drive, shut down the 
computer. If you are unsure whether the computer is off or in 
Hibernation, turn the computer on, then shut it down.
■Before removing a...

4.4 Preventing Electrostatic Damage
Many 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 the discharge contains 
enough power to alter device parameters or melt silicon junctions.
A sudden discharge of static electricity from a finger or other 
conductor...

■Store reusable electrostatic-sensitive parts from assemblies in 
protective packaging or nonconductive foam.
■Use transporters and conveyers made of antistatic belts and 
roller bushings. Ensure 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.

4.7 Grounding Equipment and Methods
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, 
connect a...

Other grounding equipment recommended for use in preventing 
electrostatic damage includes:
■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...

Removal and Replacement
Procedures
This chapter provides removal and replacement procedures.
Both Phillips P0 and Torx T8 screws are removed during 
disassembly. There are 37 screws and screwlocks, in seven 
different sizes, that must be removed and replaced when servicing 
the notebook. Make special note of each screw size and location 
during removal and replacement.
Refer to Appendix C, “Screw Listing,” for detailed information 
on screw sizes, locations, and usage....
