System Disassembly

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:

Wrist-grounding strap and conductive mat for preventing electrostatic discharge

Philips screwdriver

Flat screwdriver

Hex screwdriver

Flat plastic 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

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.

Equivalent Torque Values

Torque values indicated in this chapter are expressed in kgf-cm (kilogram force-centimetre). For equivalent values in in-lb (inch-pound force) and Nmm (milli Newton meter), refer to the table below.
