Dell Inspiron 3800 - Manual (Page 51)

To remove a memory module, perform the following steps.
NOTICE: To avoid damaging the system board, remove the power cable, the battery, and the second
battery (if installed) before you service the computer.
1. Remove the memory module cover.
NOTICE: To avoid possible damage to the memory module from electrostatic discharge (ESD), ground yourself by
touching the unpainted metal surface of an I/O connector on the computer
’s back panel.
2. To release a memory module from its socket, carefully spread apart the inner tabs of the memory module
socket just far enough for the memory module to disengage from the socket (it should pop up slightly) (see
Figure 8 ).
3. Lift the memory module out of its socket.
To install a memory module, perform the following steps:
NOTICE: If you only have one memory module, install it in the DIMM A socket. Memory modules are
keyed, or designed to fit into their sockets, in only one direction. The slots on the system board are
notched so that the memory module can be firmly seated only one way.
1. Align the memory module ’s edge connector with the slot in the center of the memory module socket.
2. With the module at a 45-degree angle, press the memory module ’s edge connector firmly into the memory
module socket.
3. Pivot the memory module down until it clicks into place.
If you do not hear a click as each end of the memory module snaps into the tabs, remove the memory
module and reinstall it
Keyboard Assembly
To remove the keyboard assembly, perform the following steps.
NOTICE: To avoid damaging the system board, remove the power cable, the battery, and the second

NOTICE: Make sure that the work surface is clean to prevent scratching the computer cover.
1. Close the display assembly, and turn the computer upside down on a flat work surface.

1 DIMM A
2 DIMM B
3 Memory module sockets (2)
4 Inner tabs (2 per socket)
NOTE: The 192-megabyte (MB) memory modules are designed for either the socket labeled DIMM A or
the socket labeled DIMM B; however, they are not interchangeable. Be sure that the memory module is
inserted with the double-stacked memory chips facing you. A 192-MB memory module inserted with the
double-stacked memory chips facing down does not fit properly in the socket.
