3-22 Dell Latitude XPi CD Reference and Troubleshooting Guide
NOTE: Before you begin this procedure, make sure that
the
SYSTEM SWITCH
option in the System Setup program is
set to
ON/OFF
. For instructions, see “Using the System Setup
Program” in Chapter 2.
1. Turn off the computer and peripherals, and dis-
connect them from AC power. Disconnect any
attached peripherals from the computer.
2. Make sure that the AC adapter is connected to
the computer and to AC power, or confirm that a
fully charged battery is properly seated in its
compartment.
3. Turn on the computer. Is the display on?
Allow one minute for the computer to initialize its
components before checking for signs of power.
Yes. The entire computer is receiving power; the
problem is resolved.
No. Adjust the brightness and contrast of the display.
If the display still does not show an image, continue
to step 4.
4. Turn off the computer, and reseat (remove and
reinstall) any installed memory modules.
To remove a memory module, carefully spread apart
the inner metal tabs of the memory module socket just
far enough for the memory module to disengage from
the socket (the module should pop up slightly). Then lift
the memory module away from the socket.
To reinstall a memory module, align the memory
module’s edge connector with the slot in the center
of the memory module socket. Press the memory
module’s edge connector firmly into the socket.
Pivot the memory module down until it clicks into
place. If you do not hear a sharp click, remove the
memory module and reinstall it.
NOTE: Memory modules are keyed, or designed, to
fit into their sockets in only one direction. The sock-
ets on the system board are notched so that the
memory module can be firmly seated only one way.
5. Turn on the computer. Is the display on?
Yes. The entire computer is receiving power; the
problem is resolved.
No. The display may be defective. See “Trouble-
shooting the Built-In Display” found later in this
section. If the display still does not work, connect an
external monitor and run the Dell diagnostics. (See
Chapter 4, “Running the Dell Diagnostics,” for
instructions.) If you cannot isolate the problem after
running the diagnostics, call Dell for technical assis-
tance. (See Chapter 5, “Getting Help,” for
instructions.)
Troubleshooting the Diskette Drive
During the power-on self-test (POST), the computer
checks the diskette drive, comparing its characteristics
with the system configuration information. (The diskette-
drive access indicator blinks as the computer performs
this check.)
If a failure occurs with the drive, make a copy of the
Diagnostics Checklist found in Chapter 5 and fill it out as
you complete the following procedure.
NOTE: Before you begin this procedure, make sure that
the
SYSTEM SWITCH
option in the System Setup program is
set to
ON/OFF
. For instructions, see “Using the System Setup
Program” in Chapter 2.
1. Reboot the computer by pressing
<
CTRL
><
ALT
><
DEL
>. Does the diskette-drive access
indicator blink during the boot routine?
Yes. Continue to step 2.
No. Go to step 5.
2. Does the computer display a drive error message?
Yes. See Table 3-2 for an explanation of the message,
and then continue to step 3.
No. Go to step 5.
3. Insert a bootable 1.44-MB diskette into the drive,
and reboot the computer.
4. Does the diskette-drive access indicator blink
during the boot routine, and does the drive boot
the operating system?
Yes. The diskette drive problem has probably been
resolved. If you continue to experience trouble, con-
tinue to step 5.
No. Continue to step 5.
5. Call Dell for technical assistance.
