A system memory problem can be a faulty dual in-line memory module (DIMM) or a
faulty system board. If a random-access memory (RAM) error message appears, the
system probably has a memory problem.
When you turn on or reboot the system, the Caps Lock and Scroll Lock indicators on
the keyboard should flash momentarily and then turn off. If
Num Lock
in the System
Setup program is set to
On
, the Num Lock indicator should flash momentarily and
then remain on; otherwise, it should turn off. Abnormal operation of these indicators
can result from a defective DIMM in socket DIMM_A.
Follow these steps to troubleshoot system memory:
1.
Turn on the system, including any attached peripherals.
Is there an error message indicating invalid system configuration information
after the memory count is completed?
Yes.
Go to step 2.
No.
Go to step 10.
2.
Enter the System Setup program and check the
System Memory
setting.
See Chapter 4, “Using the System Setup Program,” in the
User’s Guide
for
instructions.

System Memory
setting?
Yes.
Go to step 10.
