HP 701977-BA1 User Manual

Reverse this procedure to install a primary memory module.

Expansion memory slots are located in a compartment on the bottom of the computer.

A computer having a system board with spare part number 690034-001 or 688745-001 has two
memory slots, which are called primary memory slots in this MSG. When you add or replace memory
modules, slot 1 must be populated before slot 2 is populated.

A computer having a system board with spare part number 688746-001 or 690035-001 has four
memory slots. On these computers, in both the expansion memory slots (on the bottom of the
computer) and the primary memory slots (under the keyboard), slot 1 must be populated before slot 2
is populated.
