Chapter 3 23
This chapter provides step-by-step instructions on how to disassemble the notebook computer for
maintenance and troubleshooting purposes.
Disassembly Tools
In performing the disassembly process, you will need the following tools:
T Wrist-grounding strap and conductive mat for preventing electrostatic discharge
T Philips screwdriver
T Flat screwdriver
T Hex screwdriver
T Flat plastic screwdriver
T Plastic tweezers
Stages of the Disassembly Process
The disassembly process is divided into three stages:
1. External modules disassembly
2. Main unit disassembly
a. Upper case disassembly
b. Lower case disassembly
3. LDC module disassembly
IMPORTANT: The disassembly procedure described in this chapter is a gradual process, as illustrated in the
flowcharts preceding each disassembly stage section. This means that users need to observe
the instructions in a step-by step manner. To illustrate, removing the HDD assembly will require
that you first remove the battery pack and the stylus. Failure to observe the gradual flow of the
process may result in component damage.
NOTE: To reinstall the system components and assemble the unit, perform the disassembly procedures
in reverse.
