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.
