The following table shows the available memory on a
system with an 8MB base memory with different sizes of
SO-DIMM.
Memory errors might stop system operations or cause
error codes to be displayed.
Use the following procedure to isolate memory problems:
Note: Make sure that the SO-DIMM is fully installed
in the connector. A loose connection can cause an
error. For more information about installing
SO-DIMMs, see “FRU Removals and Replacements”
on page 161.
1. Power-on the computer. Press the F1 key any time
while the POST memory count is proceeding. At the
end of the memory test, the Easy-Setup screen
appears.
2. Select Test and press Enter.
3. Press Ctrl
+
A to enter advanced diagnostics.
4. Select Memory and press Enter to run the memory
test on base memory.
If an error appears below 3 712KB on a system
with a 4MB base memory (7 808KB with an 8MB
base memory), replace the bottom system board.
If an error appears above 3 712KB on a system
with 4MB base memory (7 808KB with an 8MB
base memory), replace the SO-DIMM.
5. If after replacing the SO-DIMM, an error above
3 712KB on a system with a 4MB base memory or
7 808KB with an 8MB base memory still appears,
replace the bottom system board.
6. To exit from the test screen, press Esc.
If memory problems occur intermittently, use the loop
option to repeat the test. For more information on running
the loop test, see “Running the Diagnostics” on page 156.
When the test detects an error, an error log is printed on
the printer connected to the parallel port. See “Printing
and Displaying Error Logs” on page 157 for more
information.
Do not replace FRUs because of a single, nonreproducible
failure. Single failures can occur for a variety of reasons
that have nothing to do with a hardware defect, such as
electrostatic discharge or software errors. Consider
replacing a FRU only when a recurring problem exists. If
you suspect that problems besides a failing FRU exist,
