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 chap ter is a gradual process, as illustrated in the 
flowcharts preceding each disassembly stage sect ion. This means that users need to observe 
the instructions in a step-by step manner. To illu strate, if you want to remove the mainboard, 
you must first remove the keyboard, then disassemb le the inside assembly frame in that order. 
Failure to observe the gradual process may result in component damage.   
NOTE:   To reinstall the system component s and assemble the unit, perform the disassembly procedures in 
reverse.
