Machine Disassembly and Replacement0
This chapter contains step-by-step procedures on how to disassemble the notebook 
computer for maintenanc e and troubleshooting.
Cable paths and positioning may not represent the actual model. During the removal and 
installation of the components, ensure all ava ilable cable channels and clips are used and 
that the cables are replaced in the same position.
The screws for the different components vary in size. During the disassembly process, group 
the screws with the corresponding components to avoid mismatch when putting back the 
components.
The product previews seen in the disassembly procedures may not represent the final 
product color or configuration.
Recommended Equipment0
To disassemble the computer, the following tools are suggested:
Wrist grounding strap and conductive ma t for preventing electrostatic discharge
Non-marring scribe
Phillips screwdriver
Flat-blade screwdriver
Plastic flat screwdriver
Plastic tweezers
Cyanoacrylate glue
Replacement Requirements0
NOTE:NOTE:
Cabling and components require adhesive to  be applied during the replacement and 
reassembly process.
