This manual provides instructions for removing and replacing field-replaceable
components, assemblies, and subassemblies in your Dell Latitude portable
computer. Unless otherwise noted, each procedure in this manual assumes
that a part can be replaced by performing the removal procedure in reverse
order.
It is recommended that you use a book or something similar to support the
display assembly when it is open nearly 180 degrees. The angle of the display
assembly with respect to the bottom case should never be allowed to exceed
180 degrees. Also, when performing the procedures in this manual, the
locations or directions relative to the computer are as shown in Figure 1 unless
otherwise specified.

1. If you only have one memory module, install it in the DIMM A socket.
NOTES: 192-MB memory modules are designed for either the socket
labeled DIMM A or the socket labeled DIMM B; 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.
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.

name of the LCD panel manufacturer faces up. The manufacturer is either
Torisan (T-Sanyo) or Sharp.
The connectors are identical on the Torisan and Sharp LCD panels, but they
are mounted reverse with respect to each other. This means that pin 1 on
the Torisan panel connector is at the opposite end when compared to pin 1
on the Sharp panel connector.
The LCD flex cable can connect to either panel by making one fold to the
cable. The words Torisan and Sharp are printed on the cable (see
