his document updates information contained in the Dell Latitude XPi CD
Service Manual and in the Dell Latitude XPi CD Parts Removal and Replacement Guide.

New System Features
Additional system features include:

• Now available with a 166-MHz Intel® Pentium® microprocessor with
MMX™ technology in the Dell Latitude XPi CD M166ST, which otherwise
has the same features as other models of the computer.

• Support for up to 80 MB of system memory on the Latitude XPi CD
M166ST, by installing a combination of 8-, 16-, and 32-MB memory modules in the two sockets on the system board. (The standard minimum
configuration is 16 MB of nonremovable EDO memory on the system
board.)

• The Pentium microprocessor with MMX technology has twice the internal
cache memory (32 KB) as the standard Pentium microprocessor.

• A Texas Instruments PCI 1131 CardBus controller.
• A NeoMagic 2093 video controller for a video subsystem that includes
1.1 MB of video memory.

• An ESS 1887 audio controller.
• 10X CD-ROM drive.
NOTE: Your computer may not appear exactly as shown in some of the figures
in the Service Manual. EMI shields may have been changed or added.

Removing 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, gently 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.

LCD Panel
Your computer may have a metal spacer attached to the top of the LCD panel.

Dell Latitude XPi CD Service Manual Update

LCD Inverter Board
The inverter board assembly with order name SVC,LCD/INVTR,IBM,LXPiCD
(see the “Factory Repair Parts and Assemblies” table found later in this
document) is different from the inverter board assembly with order name
SVC,LCD/INVTR,SMSNG,LXPiCDX.
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 Figure 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 Figure 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.

Advanced Port Replicator Connector Dust Cover
The callout in Figure 4-31 (Figure 31 of the Parts Removal and Replacement
Guide) refers to the Advanced Port Replicator connector dust cover.

Audio Board
The parts of your computer may be different from the parts shown in
Figure 4-32, “Audio Board Removal,” of the Service Manual (Figure 32 of the
Parts Removal and Replacement Guide). The hard-disk drive bracket and the
audio board may have a shield, a clip, an insulator, and standoffs added.

Factory Repair Parts Changes
Removal and replacement procedures for all factory components and subassemblies are the same as those described in Appendix A, “Factory Repair Parts,” of
