This chapter provides step-by-step instructions on how to disassemble the notebook computer for maintenance and troubleshooting purposes.
Stages of the Disassembly Process
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.
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.
Listed below are the screw types used in this system, plus their corresponding part numbers.
NOTE: The screws for the different components vary in size. During the disassembly process, group the screws with their corresponding components to avoid mismatches when putting back the components.
Before proceeding with the disassembly procedure, perform the steps listed below:
