A prerequisite for using this manual to service Dell computer systems is a basic
knowledge of PCs and prior training in PC troubleshooting techniques. In
addition to information provided in this manual and the online Systems User’s
Guide that came with the system, Dell provides the Diagnostics and Troubleshooting Guide for troubleshooting procedures and instructions on using the
Dell diagnostics to test the computer system.
Throughout this guide, blocks of text may be accompanied by an icon and printed
in bold type or in italic type. These blocks are notes, cautions, and warnings, and
they are used as follows:
NOTE: A NOTE indicates important information that helps you make better use
of your computer system.

This guide provides instructions for removing and replacing field-replaceable
components, assemblies, and subassemblies. Unless otherwise noted, each
procedure in this guide assumes the following:
The computer and any attached peripherals are turned off, and the
peripherals are disconnected from the I/O panel on the back of the
computer.
A part can be replaced by performing the removal procedure in reverse
order.
When the display assembly is open nearly 180 degrees, use a book or
something similar to support it. The angle of the display assembly with respect
to the bottom case should never be allowed to exceed 180 degrees. Also,
when performing the procedures in this guide, the locations or directions
relative to the computer are as shown in Figure 1 unless otherwise specified.

Before you start to work on the computer, perform the following steps:
1.
To avoid possible damage to the computer from ESD, periodically
ground yourself by touching the metal surface of an I/O connector
on the computer’s back panel.
2.
Save any work in progress and close all open application programs.
3.
Turn off the computer and any attached peripherals.
NOTE: Make sure the computer is turned off and not in suspend-to-disk
mode. If you cannot shut down the computer using the computer’s
operating system, press the power button for 4 seconds.
4.
If the computer is docked in a C/Port Advanced Port Replicator (APR)
or C/Dock Expansion Station, undock the computer.
5.
Disconnect the computer and any attached peripherals from
AC power sources to reduce the potential for personal injury or
shock. Also disconnect any telephone or telecommunications lines
from the computer.
6.
Disconnect all other external cables from the computer.
7.
Remove any installed PC Cards.
&''
8.
Remove any diskette drive, CD-ROM drive, travel module, or battery
installed in the modular bay. Close the display and turn the computer
over. Push the modular bay latch away from the center of the
computer. While holding the latch with one hand, pull the device
out of the modular bay with the other hand.
9.
Remove the main battery assembly from the battery bay.
Slide the battery bay latch away from the center of the computer. Then
slide the battery out of the battery bay (see Figure 2).

The illustrations in the following removal procedures provide the correct screw
length as part of the screw’s label. A graphic for that length screw is also
included in the illustration. Match the actual screw to the graphic in the

connector
(do not remove)
#$ "
Some of the computer’s interface connectors are zero insertion force (ZIF)
connectors. These connectors are not removable, but they must be released
to disconnect a cable from them.
(#
%
To disconnect an interface cable from a ZIF connector, follow these steps:
1.
Insert a small flat-blade screwdriver under the movable part of the
connector.
2.
Pull gently upward on the movable part of the connector until it
releases the interface cable.
3.
Grasp the interface cable and pull it out of the connector.
To reconnect an interface cable to a ZIF connector, follow these steps:
1.
Use a small flat-blade screwdriver to open the movable part of the ZIF
connector.
2.
Orient the end of the interface cable with the ZIF connector, and
insert the end of the cable into the connector.
3.
While holding the cable in place, close the ZIF connector.
To ensure a firm connection, make sure the ZIF connector is completely
closed.

7.
Before replacing the LCD panel, ensure that the correct magnet is
installed in the magnet holder.
A magnet switch causes the computer to go into suspend mode when the
display is closed. Failure to install the correct magnet in the magnet holder
may prevent the computer from going into suspend mode. Begin by
checking the back of the LCD panel for the manufacturer’s label, and then
follow the instructions for that manufacturer.
Sharp LCD Panel
Some revisions of the Sharp LCD panel have a magnetic frame and
require a single, large magnet, or two small magnets with no foam spacer,
for the magnet switch to operate properly. Other revisions of the Sharp
LCD panel have a nonmagnetic frame and require a single, small magnet
with a foam spacer. To identify the revision of the LCD you are working
with, follow these steps:
a.
Remove the magnet from the magnet holder (see Figures 19 and
20), and place it against the replacement LCD panel frame.
b.
If the magnet sticks, the LCD panel has a magnetic frame. Place a
single, large magnet, or 2 small magnets with no foam spacer, in the
magnet holder.
c.
If the magnet does not stick, the LCD panel has a nonmagnetic frame.
Place a single, small magnet and a foam spacer in the magnet holder,
as shown in Figure 20. Place the magnet to the left of the foam spacer,
assuming you are facing the display as shown in Figure 19.

3.
Remove the speaker from the bottom case bracket.
NOTES: When replacing the speaker, follow these guidelines to prevent
damage to the speaker wires:
Orient the speaker in the bottom case so that the speaker wires are facing
upwards.
Route the speaker wires under their retaining clips on the bottom case
bracket.

The system board’s BIOS chip contains the system service tag number,
which is also visible on a bar-code label on the bottom of the computer. The
replacement kit for the system board assembly includes a diskette that
provides a utility for transferring the service tag number to the replacement
system board assembly.

6.
Remove the processor hold-down clip, if one is attached to the
microprocessor module fence.
Your computer may have a one- or two-slot hold-down clip. One tab locks
the one-slot hold-down clip to the fence. Two tabs lock the two-slot clip to
the fence. To remove the clip, perform the following steps to bend the
tabs away from the fence:

a.
Insert a small flat-blade screwdriver into one of the slots at the top of
the clip (see Figure 31).
b.
Bend the tab away from the fence by carefully tipping the screwdriver
away from the microprocessor module.
c.
If your computer has a two-slot hold-down clip (see Figure 31), repeat
substeps a and b for the second slot.
d.
Lift the clip off the fence and discard it.

12. Remove the following two screws from the system board assembly
(see Figure 30):
The 5-mm screw near the reserve-battery cable connector
The 5-mm screw near the microprocessor module
13. Lift the system board assembly out of the bottom case assembly.
Be sure to transfer the memory module(s) to the replacement system board
assembly. If you are replacing the thermal cooling assembly with a new one,
remove any lining present on the thermal pad before installing the new thermal
cooling assembly.
After replacing the system board assembly, be sure to enter the system’s
service tag number into the BIOS of the replacement system board assembly.
Insert the diskette that accompanied the replacement system board assembly
into the diskette drive, and turn on the computer. Follow the instructions on the
display.
When you reinstall the processor module in the system board, make sure you
press down evenly at all four corners of the module. When the processor
module is seated, all four corners must be at the same height. If one or more
corners of the module are higher than the others, the module is not seated
correctly. To ensure the processor module is seated correctly, look at the holes
on the processor-module fence. You should see no less than the top half of the
holes all the way around the processor module (see Figure 32). Install the
three screws to secure the processor module to the system board. Place a
new processor hold-down clip (either a one-slot or two-slot clip) over the
corner of the fence as shown in Figure 32. Press the clip down to lock it in
place. Do not reuse the old clip.

Remove the two 12-mm screws securing the exhaust fan, and then
remove the exhaust fan.
NOTE: When replacing the exhaust fan, orient the fan such that the fan label
faces outward and the power cable is at the upper right corner of the fan
(when viewed from the back of the computer). (This will prevent the fan wires
from being pinched when you reassemble the computer.) Make sure that the
wires are routed below the upper EMI shield.
