Machine Disassembly and Replacement
WARNING:This computer has two highly sensitive touchscreen sensors on the top left and right
corners of the LCD. The sensors are an integral part of the LCD and cannot be separately
replaced. The sensors are exposed as soon as the rear cover is removed.
During disassembly:
•
DO NOT make contact with the sensors.
•
Raise the LCD off any surface it is placed face down on so that the sensors do not rest on
the surface.
•
ALWAYS employ an antistatic mat.
IMPORTANT:
The outside housing and color may vary from the images that appear in this section.
This chapter contains step-by-step procedures on how to disassemble the 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
•
Three (3) sizes of Philips screwdrivers: 7mm, 4mm and 2mm
•
Pin or unbent paperclip or similar.
•
Block of sponge or similar soft material smaller in surface area than the LCD and at least 1”
(2.5cm) high.
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.
