Adding and Replacing Parts 87
The computer has two memory slots, DIMM A and DIMM B, both located on the bottom of the
computer under the memory module/Mini PCI cover. DIMM A holds the basic memory module as
configured from the factory. If you did not order additional memory, DIMM B will be empty. Generally, if
you are adding memory, you will install a memory module in DIMM B. If you are upgrading memory, you
may need to install memory in DIMM A and B depending on the extent of the upgrade.
