NOTE: Primary and expansion memory is installed in a side-by-side conīguration in the bottom of the
computer.
If only one memory module is installed, it must be installed in the socket labeled 1.

IMPORTANT: Before adding new memory, make sure you update the computer to the latest BIOS, available
at www.hp.com.
Before removing the memory module, follow these steps:
1. Prepare the computer for disassembly (Preparation for disassembly on page 32).
2. Remove the bottom cover (see Bottom cover on page 32).
3. Disconnect the battery cable from the system board (see Battery on page 44).
Remove the memory module:
1. Spread the retaining tabs (1) on each side of the memory module slot to release the memory module.
(The edge of the module opposite the slot rises away from the computer.)
2. Remove the memory module (2) by pulling the module away from the slot at an angle.
NOTE: Memory modules are designed with a notch to prevent incorrect insertion into the memory
module slot.
NOTE: The computer uses two memory sockets. The socket labeled 2 houses the expansion memory
module and the socket labeled 1 houses the primary memory module. The removal procedure is the
same for both memory sockets.
Reverse this procedure to install a memory module.
