Acer Extensa 670 Notebook
The Extensa 67x Series follows the 65x Series. The Extensa
series is similar in
construction and appearance, has similar operating controls
and indicators and uses the same
software. It uses a similar startup self test program
(described in detail in Chapter 5 of this manual).
There are differences at the board level which affect
assembly/disassembly as described in Chapter
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
