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
