Memory problems
Memory problems Action
The amount of memory
displayed is less than the
amount of memory
installed. The amount of available memory shown might be
somewhat less than expected because basic
input/output system (BIOS) shadowing takes some
random access memory (RAM) and ACPI and USB can
take up to 1 MB.
Verify that:
1. You have installed the correct type of DIMMs for
your computer. See “Working with memory” on
page 76 for instructions on adding DIMMs.
2. The DIMMs are properly installed and securely
connected.
3. If you added or removed memory, you saved the
new configuration before exiting the
Configuration/Setup Utility program.
If the problem persists, run the memory test from the
diagnostic program supplied with your computer. (See
“IBM Enhanced Diagnostics program” on page 122 for
further information.) The system might have detected
a bad DIMM and automatically reallocated memory to
enable your computer to continue to operate.
If you cannot correct the problem, have the computer
serviced.
