emoving and Replacing Parts Changes
The following information updates the removal and replacement procedures for
some parts and assemblies as described in Chapter 4, “Removing and Replacing
Parts,” of the Service Manual and in the Parts Removal and Replacement Guide
(which is the same as Chapter 4 of the Service Manual). However, some of the
parts and assemblies used are different.
Palmrest Assembly
Revise the Palmrest Assembly removal procedure to include the following:
Use a scribe to pry out the three screw covers for the palmrest-retaining screws
A1, A2, and A3.
Disengage the palmrest assembly from the bottom case assembly by sliding the
palmrest assembly about 1/8-inch toward the front of the computer. Then, gen-
tly lift the front of the palmrest assembly and pull it toward the front to release
the back hooks.
Display Assembly Latch and Latch Spring
Your computer may have a plastic clip or mylar pad attached to the latch
assembly.

If the back light on the LCD panel is not working, replace both the inverter
board and the LCD panel.
Bottom Case Assembly Removal
The parts of your computer may be different from the parts shown in Fig-
ure 4-22, “Bottom Case Assembly Removal,” of the Service Manual (Figure 22
of the Parts Removal and Replacement Guide). The superpart docking EMI clip
and superpart serial EMI clip may be smaller. The superpart assembly may also
look different. The upper I/O bracket clip has been renamed the deck buoy.
Diskette/CD-ROM Drive Assembly
There may be a bracket spacer on the diskette/CD-ROM assembly in your
computer.
Deck Buoy
The deck buoy in your computer may have an EMI clip attached to it.
System Board Assembly Removal
The parts of your computer may be different from the parts shown in Fig-
ure 4-27, “System Board Assembly Removal,” of the Service Manual (Figure 27
of the Parts Removal and Replacement Guide). The battery compartment may
have a plastic cover.
