Machine Disassembly and Replacement
This chapter contains step-by-step procedures on how to disassemble the notebook computer for
maintenance and troubleshooting.
To disassemble the computer, you need the following tools:
•Wrist grounding strap and conductive mat for preventing electrostatic discharge
•Plastic flat screwdriver
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.

Before proceeding with the disassembly procedure, make sure that you do the following:
1.Turn off the power to the system and all peripherals.
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.
The disassembly process is divided into the following stages:
•External module 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 main board, you must first remove the keyboard, then disassemble the inside assembly
frame in that order.

Removing the Battery Pack
1.Turn computer over.
2.Slide the battery lock/unlock latch to the unlock position.
3.Slide and hold the battery release latch to the release position (1), then slide out the battery pack from the main
