Machine Disassembly and Replacement
This chapter contains step-by-step procedures on how to disassemble the notebook computer for 
maintenance and troubleshooting.
Disassembly Requirements
To disassemble the computer, you need the following tools:
• Wrist grounding strap and conductive mat for preventing electrostatic discharge
• Flat screwdriver
• Philips screwdriver
• Plastic flat screwdriver
• Plastic tweezers
NOTE: The screws for the different components vary in size. During the disassembly process, group the 
screws with the corresponding components to avoid mismatch when putting back the components.
Related Information
The product previews seen in the disassembly procedures may not represent the final product color or 
configuration.
IMPORTANT: Cable paths and positioning may not represent the actual model. During the removal and 
replacement of components, ensure all available cable channels and clips are used and that the cables are 
replaced in the same position.
Replacement Requirements
NOTE: Cabling and components require adhesive to be applied during the replacement and reassembly 
process.
NOTE: During manufacture a cyanoacrylate glue is used provided by Holdtite Adhesives LTD. This is not a 
specified requirement. The reassembler is free to select an alternative appropriate adhesive.
General Information
Pre-disassembly Instructions
Before proceeding with the disassembly procedure, make sure that you do the following:
1.Turn off the power to the system and all peripherals.
Chapter 3 
						

							40Chapter 3
2.Unplug the AC adapter and all power and signal cables from the system.
3.Place the system on a flat, stable surface. 
4.Remove the battery pack.
Disassembly Process
The disassembly process is divided into the following sections:
• External components disassembly
• Main unit disassembly
• LCD module disassembly
The flowcharts provided in the succeeding disassembly sections illustrate the entire disassembly sequence. 
Observe the order of the sequence to avoid damage to any of the hardware components. For example, if you 
want to remove the Mainboard, you must first remove the Keyboard, and LCD Module then disassemble the 
inside assembly frame in that order.
