3-26 Dell Latitude XPi CD Reference and Troubleshooting Guide
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.
3. Turn on your computer. Does the RAM count
complete?
Yes. A memory module was loose; the memory
check phase is now OK.
No. Continue to step 4.
4. Run the Dell diagnostics.
For instructions, see Chapter 4, “Running the Dell
Diagnostics.” If you get any error messages when run-
ning the tests, call Dell for technical assistance. (See
Chapter 5, “Getting Help,” for instructions.)
Troubleshooting the Built-In Display
If the computer is receiving power, but nothing appears
on your display (such as light, text, or graphics) or the
display image does not appear as you would expect,
make a copy of the Diagnostics Checklist found in Chap-
ter 5 and fill it out as you complete the following
procedure.
NOTES: 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.
The highest video resolution supported by your built-in
display is 800 x 600 pixels. If your application program
uses a higher resolution, you must attach an external
monitor to your computer.
1. If the computer is running, press a key to exit
standby mode or suspend mode or to reactivate
the display. Is the full display readable?
Yes. The computer was in standby or suspend mode,
or the display time-out feature was activated. The
problem is resolved.
No. Continue to step 2.
2. If the computer is running, is the low-battery
indicator blinking?
Yes. The display turns off when the final low-battery
warning occurs. Replace the battery or connect the
computer to alternating current (AC) power through
the AC adapter. Press a key on the keyboard. If the
display is still not readable, continue to step 3.
No. Continue to step 3.
3. Turn off the computer and any attached periph-
erals. Disconnect all peripherals from the
computer.
4. Make sure the AC adapter is firmly connected to
the computer and to an AC power source, or ver-
ify that a fully charged battery is properly seated
in its compartment.
5. Turn on the computer. Is the display on?
Allow one minute for the computer to initialize its
components.
Yes. Continue to step 6.
No. Go to step 8.
6. Use the < FN >< ↓ > or < FN >< ↑ > key combination to
adjust the brightness. Use the < FN >< ← > or
< FN >< → > key combination to adjust the contrast. Is
the full display readable?
NOTE: Contrast cannot be adjusted on the active-
matrix color display.
Yes. Continue to step 7.
No. Go to step 8.
7. Has an error message appeared on the display, or
has a beep code sounded?
Yes. Refer to Table 3-2 or Table 3-3 to find the mes-
sage or beep code, respectively, along with its
explanation. If you can’t find the message or code,
call Dell for technical assistance. (See Chapter 5,
“Getting Help,” for instructions.)
No. If you still have a display problem but the dis-
play is not completely blank, run the Video Test
Group in the Dell diagnostics. (See Chapter 4, “Run-
ning the Dell Diagnostics,” for instructions.) Then
call Dell for technical assistance. (See Chapter 5,
“Getting Help.”)
8. Turn off your computer, and connect an external
monitor to the computer.
Follow the procedure in the topic titled “Connecting
an External Monitor” in the online System User’s
Guide.
