Acer Aspire 4732Z/4332 Service Guide 25
This chapter provides step-by-step instructions on how to disassemble the computer for maintenance and
troubleshooting purposes.
Disassembly Tools
In performing the disassembly process, you will need the following tools:
• Wrist-grounding strap and conductive mat for preventing electrostatic discharge
•
Philips screwdriver
• Flat screwdriver
•
Plastic flat-blade screwdriver
• 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
c. 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, if you want to remove the mainboard,
you must first remove the keyboard, then disassemble the inside assembly frame in that order.
Failure to observe the gradual process may result in component damage.
NOTE: To reinstall the system components and assemble the unit, perform the disassembly procedures in
reverse.
