Removing the Memory Module
Verifying the expanded memory
To remove a memory module, remove the right cover and the
memory slot cover from the machine. Then, carefully push
out the two socket clamps. Ease the memory module out of
the socket to remove.
To verify that the memory module is working properly, test it
by printing a status page.
