Acer Aspire 5910 Service Guide

							
Chapter 323
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:
TWrist-grounding strap and conductive mat  for preventing electrostatic discharge
TPhilips screwdriver
TFlat screwdriver
THex screwdriver
TFlat plastic screwdriver
TPlastic 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 chap ter 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 styl us. 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.
