General Description 1-1 1 General Description 1.1 Introduction This manual contains field and factory level servicing information for the ExtensaTM 60x and 65x Series Notebook Computers manufactured for Texas Instruments. The first six sections contain information common to all members of the Extensa 60x/65x Family of Notebook Computers (any differences are described); the appendices contain model dependent maintenance information. This section provides a general overview of the Extensa 60x/65x Series, describes the standard and optional features, and identifies the major assemblies and subassemblies. This section also contains detailed functional and environmental specifications for the Extensa 60x/65x Series Notebook Computers. Figure 1-1 Extensa 60x/65x Series Notebook Computers
1-2 General Description 1.2 Product Overview The Extensa Series contains two major product lines including: ¨60x Series ¨65x Series Both notebook series are similar in construction and appearance, have similar operating controls and indicators and use the same software. Both notebook series use a similar startup self test program and diagnostics program (described in detail in Section 5 of this manual). There are differences at the board level which affect assembly/ disassembly as described in Section 6 of this manual. There are also differences in Field-Replaceable Units (FRUs), particularly the Printed Circuit Boards, so separate FRU lists and logic diagram sets are provided in the appendices. Table 1-1 summarizes some of the major differences between the 60x Series and the 65x Series Notebook Computers.
