Tecra 750 Series Disassembly Overview
This section explains how to remove Field
Replaceable Units (FRUs). It may not be neces-
sary to remove all the FRUs in order to replace
one.
The chart is a guide to which FRUs need to be
removed in order to remove others. The section
numbers on the chart refer to the sections in the
Maintenance Manual, Chapter 4.
Always start by removing the battery pack, next,
optional items such as the optional PC card and
optional memory module, then follow the line on
the chart to determine which FRU you must
remove next in order to repair the one you think is
causing the computer to operate improperly.

nance Manual through the Toshiba Service and Support Website before you proceed.
