The portable computer has nine indicators: six on the display assembly’s indicator panel and three on the keyboard assembly. Each of the six indicators on the
display assembly has an identical pair of LEDs: one is visible on the indicator
panel when the display is open, and the other is visible through an aperture on
the outside of the display assembly when the display is fully closed. The subsections that follow describe the functions of the indicators.
Power/Suspend Indicator
The power/suspend indicator is a green LED. After the computer is turned on,
the power/suspend indicator lights up constantly to indicate that the computer is
receiving stable power. When the computer enters suspend mode, the indicator
blinks once approximately every 8 seconds.
Diskette-Drive Access Indicator
The diskette-drive access indicator is a green LED. The indicator lights when
data is being transferred to or from the diskette drive.
Hard-Disk/CD-ROM Drive Access Indicator
The hard-disk/CD-ROM drive access indicator is a green LED. The indicator
lights when data is being transferred to or from the hard-disk drive or the
CD-ROM.
PC Card Access Indicator
The PC Card access indicator is a green LED. The indicator lights when data is
being transferred to or from an installed PC Card (also known as a PCMCIA
card).
Low-Battery Indicator
The low-battery indicator is an amber LED. This indicator is used in conjunction with the speaker to indicate either of the following low-battery conditions:
• The first low-battery warning occurs when the main battery’s charge has
been depleted to 8 percent of its fully charged condition. The low-battery
indicator turns on and the speaker emits five beeps.
• The second and final low-battery warning occurs when the main battery’s
charge has been depleted to 3 percent of its fully charged condition. The
speaker beeps twice every 1 to 2 seconds for 15 seconds; then the system
does a suspend-to-disk operation automatically before shutting down.
Charging Indicator
The charging indicator is an amber LED. The indicator turns on when the main
battery begins charging and blinks to show the battery is fully charged.

Keyboard Indicators
The keyboard controls the operation of the numeric lock (Num Lock) indicator,
the capitals lock (Caps Lock) indicator, and the Scroll Lock indicator, all of
which are visible through apertures at the top of the keyboard. These indicators
are associated with the <NUM LOCK> key, the <CAPS LOCK> key, and the
<SCROLL LOCK> key; when lit, the LEDs indicate the active state of these
keys.
Controlling Computer Power
The power button does not directly control power to the computer. Instead,
when you slide the power button toward the front of the computer and then
release it, the button momentarily closes the power switch on the system board.
The power switch sends a signal to the power management controller, signaling
the controller to initiate a change of state of the computer’s power. The resulting
power state depends on the present power state. The following subsection gives
a description of the power states.
Power States
Sliding the power button toward the front of the computer initiates a change
from the current power state to a different state. The protocols for the power
state changes are as follows:
• If the computer is off (no indicators on) and the display is open and/or an
external monitor is attached to the computer, sliding the power button initiates a boot operation.
• If the computer is off, if the display is closed, and if no external monitor is
attached, sliding the power button causes the computer to run the POST and
then turn off.
• If the computer is on and the SYSTEM SWITCH option in System Setup is set
to ON/OFF, sliding the power button turns off the computer.
• If the computer is on and the SYSTEM SWITCH option in System Setup is set
to S2D/RFD, sliding the power button causes the computer to enter suspendto-disk mode.
• If the computer is in suspend mode (the power/suspend indicator flashes
every 8 seconds), if the SYSTEM SWITCH option in System Setup is set to
ON/OFF, and if the display is open or an external monitor is attached, sliding
the power button turns off the computer.
• If the computer is in suspend mode (the power/suspend indicator flashes
every 8 seconds), if the SYSTEM SWITCH option in System Setup is set to
S2D/RFD, and if the display is open or an external monitor is attached, sliding
the power button causes the computer to enter suspend-to-disk mode.
System Overview
1-5
• If the computer is in suspend mode (the power/suspend indicator flashes
every 8 seconds), if the display is closed, and if no external monitor is
attached, sliding the power button has no effect on the power state. The
computer remains in suspend mode.
• If the computer is in suspend-to-disk mode, sliding the power button causes
the computer to initiate the resume-from-disk operation.

Initial Procedures
T
his chapter describes initial procedures that can help you diagnose a computer problem. These procedures can often reveal the source of a problem or
indicate the correct starting point for troubleshooting the computer. Dell recommends that you perform these procedures in the order they are presented in this
manual.
Initial User Contact
When you first contact a user who has a computer problem, ask the user to
describe the problem and the conditions under which it occurs. A verbal
description can often indicate the cause of a problem or indicate the appropriate
troubleshooting procedure to use. After the user describes the problem, follow
these steps:
1. Ask the user to back up any data on the hard-disk drive if the system’s
condition permits.
See “Maintaining Your Computer” in the online System User’s Guide.
2. Ask the user to try to duplicate the problem by repeating the operations
he or she was performing at the time the problem occurred.
Can the user duplicate the problem?
Yes. Proceed to step 3.
No. Proceed to the next section, “Visual Inspection.”
3. Observe the user to determine whether he or she is making an error,
such as typing an incorrect key combination or entering a command
incorrectly.
Is the problem a result of user error?
Yes. Instruct the user in the proper procedure, or direct him or her to the
appropriate user documentation for a description of the correct procedure.
No. Proceed to the next section, “Visual Inspection.”
Visual Inspection
The visual inspection consists of a quick inspection of the exterior of the
computer and any attached peripherals, including making any necessary corrections. For information about the proper removal and installation of computer
Initial Procedures

components, as instructed in the following procedures, see Chapter 4, “Removing and Replacing Parts.”
CAUTION: Before you proceed with the visual inspection, ensure that
the user has saved all open files and exited all open application programs
if possible.
To perform a visual inspection, follow these steps:
1. Turn off any attached peripherals.
2. Determine the present power state of the computer.
Look at the indicators to determine which of the following conditions apply,
and then turn off the computer, taking the actions listed for that condition:
• Power/suspend indicator is blinking approximately every 8 seconds —
The computer is in suspend mode. Open the display and press any key to
return the computer to the power-on state. If the computer does not turn
on, press <FN><B> to return from battery-swap mode. Then slide the
power button to turn off the computer.
• Low-battery indicator is on or blinking — A low-battery warning
occurred; open the display and slide the power button to turn off the
computer.
• Low-battery and charging indicators are both blinking — A defective
battery is detected or the computer is too warm; slide the power button
to turn off the computer.
• All indicators remain off — The computer is already turned off or is in
suspend-to-disk mode.
3. Verify that the exterior of the computer is free of any obvious physical
damage.
4. If the computer is operating from an AC adapter, verify the following:
• The AC adapter’s AC power cable is connected to the AC adapter and
the power source.
• The AC adapter’s DC power cable is properly connected to the computer’s DC power input connector.
• The AC adapter and cables are free of any obvious physical damage.
NOTE: If the charging indicator and low-battery indicator flash continuously while the computer is connected to AC power, disconnect the computer
from AC power and move it to a cooler location. When the computer has
cooled to room temperature, reconnect it to AC power and continue charging
the battery. If the computer is not allowed to cool, the battery stops charging
before it reaches full capacity.
2-2
Dell Latitude XPi CD Service Manual
5. If the computer is operating from battery power, remove the main battery assembly, verify that it is free of any obvious physical damage, and
then reinsert the battery assembly into its compartment.
6. Turn off the computer. Remove the hard-disk drive, verify that it is free
of any obvious physical damage, and then reinsert the drive into its
compartment.
7. Remove any installed PC Cards from the PC Card slot, verify that they
are free of any obvious physical damage, and then reinsert the card(s)
into the PC Card slot.
8. Remove any memory modules from the memory compartment, verify
that they are free of any obvious damage, and then reinstall the memory modules.
9. Open the display assembly, and verify that it is free of any obvious
physical damage.
10. Verify that the internal keyboard is free of any obvious physical damage and that its keys operate freely.
11. Verify that the trackball and its associated switches operate freely.
12. If an external monitor is connected, verify the following:
• The monitor’s interface cable is properly attached to the VGA connector
on the I/O panel.
• The monitor’s power cable is attached to a power source and is free of
any obvious physical damage.
• The monitor’s controls are set according to the instructions in the documentation for the monitor.
• The monitor and its interface cable are free of any obvious physical
damage.
13. If an external mouse is connected, verify the following:
• The mouse is properly connected to the keyboard/keypad/mouse connector on the computer’s I/O panel.
• The mouse and its cable are free of any obvious physical damage.
• The mouse’s ball and push buttons operate freely.
14. For any attached serial or parallel devices, verify the following:
• The device’s interface cable connector is correctly attached to the appropriate port connector on the computer’s I/O panel.
• The captive screws that secure the connectors at each end of the interface cable are secure enough to ensure a firm connection.
• The attached device and its interface cable are free of any obvious physical damage.
Initial Procedures
2-3
15. Turn on any attached peripherals and then the computer.
Does the problem reoccur?
Yes. Proceed to the next procedure, “Observing the Boot Routine.”
No. No further steps are necessary.
Observing the Boot Routine
After you perform a visual inspection as described in the previous section, boot
the computer from a diagnostics diskette and, while the boot routine is running,
observe the computer for any indications of problems.
NOTE: To prevent possible damage to the original diagnostics diskette, always
use a backup copy of the diagnostics diskette when servicing a user’s computer.
Dell recommends that users make copies of the Dell diagnostics diskette. For
instructions, see “Before You Start Testing” in Chapter 4 of the Reference and
Troubleshooting Guide.
To observe the boot routine, follow these steps:
1. Turn off the computer and any attached peripherals.
2. Insert a diagnostics diskette into the diskette drive. Turn on all peripherals and then the computer.
3. Watch the indicators on the top of the keyboard. After all three indicators flash momentarily, the Num Lock indicator should light up and
remain on.
Do these indicators light up within approximately 10 seconds after the boot
routine starts?
Yes. Proceed to step 4.
No. Troubleshoot the power subsystem.
4. While the boot routine is running, observe the computer for any of the
following:
• Diskette-drive and hard-disk drive access indicators — These indicators
light in response to data being transferred to or from the drives. If either
of these indicators fail to light during the boot routine, troubleshoot the
diskette-drive or hard-disk drive subsystem, as appropriate.
• Beep codes — A beep code is a series of beeps that indicates an error
condition. If the computer emits a beep code, go to Table 3-1.
NOTE: The computer beeps once during the boot routine. This single
beep is normal and is not a beep code.
• System error messages — These messages can indicate problems or
provide status information. If a system error message displays, go to
Table 3-2.

Dell Latitude XPi CD Service Manual
5. Observe the display for the Diagnostics Menu.
Does the Diagnostics Menu display?
Yes. See “Running the Dell Diagnostics” in Chapter 3.
No. Proceed to step 6.
6. Insert another copy of the diagnostics diskette into the diskette drive,
and reboot the computer.
Does the Diagnostics Menu display?
Yes. See “Running the Dell Diagnostics” in Chapter 3.
No. Proceed to the next section, “Eliminating Resource Conflicts.”
Eliminating Resource Conflicts
Devices within the computer may require dedicated memory spaces, interrupt
levels, or DMA channels, all of which must be allocated during installation of
the devices. Because a device may be installed at a different time, it is possible
that the same resource is assigned to two or more devices.
Resource conflicts can result in disorderly or erratic computer operation or failure of the computer to operate at all. If you suspect that resource conflicts might
exist, check the computer and reassign the resources as necessary.
For more information about resolving conflicts, see Chapter 3, “Troubleshooting Your Computer,” in the Reference and Troubleshooting Guide.
Getting Help
If none of the procedures in this chapter reveal the source of the problem or lead
to the proper troubleshooting steps for determining the source of the problem,
call Dell for technical assistance. For instructions, see Chapter 5, “Getting
Help,” in the Reference and Troubleshooting Guide.

Beep Codes and Error Messages
T
his chapter describes beep codes and system error messages that can occur
during computer start-up or, in the case of some failures, during normal computer operation. The tables in this chapter list faults that can cause a beep code
or system error message to occur and the probable causes of the fault in each
case.
If a faulty computer does not emit beep codes or display system error messages
to indicate a failure, use the Dell diagnostics to help isolate the source of the
problem. See “Running the Dell Diagnostics” found later in this chapter.
POST Beep Codes
If the display cannot display error messages during the POST, the computer
may emit a series of beeps that identifies the problem or that can help you identify a faulty component or assembly. The following table lists the beep codes
that may be generated during POST. Most beep codes indicate a fatal error that
requires replacement of the system board or other corrective actions before the
computer can operate.

Removing and Replacing Parts
T
his chapter provides instructions for removing and replacing fieldreplaceable components, assemblies, and subassemblies. For removal and
replacement procedures for factory-replaceable parts, see Appendix A,
“Factory Repair Parts.”
Unless otherwise noted, each procedure in this chapter 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 the display assembly. 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 chapter, the locations or directions relative to the computer are as shown in Figure 4-1 unless otherwise specified.

Figure 4-4. Disconnecting an Interface Cable
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.
CAUTION: The ZIF connectors are fragile. To avoid damage, do not
apply too much pressure to the movable part of the connector.
To disconnect an interface cable from a ZIF connector, follow these steps:
1. Insert a small flat-blade screwdriver or a chip-removal tool under the
movable part of the connector.
If a small flat-blade screwdriver is unavailable, use a chip-removal tool to
carefully pry up on first one end of the movable part of the connector and
then the other end.
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 flat-blade screwdriver or chip-removal tool 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.

CAUTION: Use care when handling the diskette/CD-ROM drive; it is
fragile and will bend if handled improperly. Place the assembly on a flat
work surface, and carefully remove the small 2-mm screws. Do not bend
either the drives or the bracket. If bending occurs, the diskette or
CD-ROM will not function correctly when inserted in the drive.
To separate the diskette/CD-ROM assembly into a diskette drive and a
CD-ROM drive, remove screws D3 through D9. Lift up the CD-ROM, and
remove it from the assembly. Slide the CD-ROM flex cable out of the slot in the
bracket that holds the CD-ROM to the diskette drive.

Hard-Disk Drive
The hard-disk drive resides in a carrier that mounts inside the computer’s
hard-disk drive bay. Four screws secure the drive inside the carrier. A mylar
insulator provides electrical insulation between the hard-disk drive and the bottom of its carrier. To remove the hard-disk drive and hard-disk drive insulator,
follow these steps:
1. Remove the hard-disk drive assembly.
See “Hard-Disk Drive Assembly” in Chapter 4.
2. Place the hard-disk drive assembly right side up on the work surface,
and remove the four screws that secure the drive in its carrier.
CAUTION: Rotating the hard-disk drive too far can damage the
short flex cable that connects the hard-disk drive to the system
board’s hard-disk drive interface connector. Do not rotate the drive
farther than necessary to disconnect the cable from the back of the
drive.
3. Rotate the front of the drive toward the back of the carrier far enough
to expose the connector on the back of the drive.
4. Carefully pry the flex cable connector away from the hard-disk drive
interface connector on the back of the drive.
5. Lift the hard-disk drive out of its carrier.
6. Remove the hard-disk drive insulator, if necessary.
With the hard-disk drive removed, lift the insulator straight up out of the
carrier. The 17-mm hard-disk drives also have a foam spacer on top of the
insulator (not shown).
To avoid possible damage to components on the hard-disk drive’s integrated
controller board, hold the drive at approximately a 45-degree angle while reattaching the interface cable. Then rotate the drive toward the front of its carrier
until it is seated in its original position.
