1 Introduction
This manual covers the information you need to service or upgrade the 3220/3420/3620 Notebook Computer.
Information about operating the computer (e.g. getting started, and the Setup utility) is in the User’s Manual. Infor-
mation about drivers (e.g. VGA & audio) is also found in User’s Manual. That manual is shipped with the computer.
Operating systems (e.g. DOS, Windows 9x, Windows NT 4.0, Windows 2000, UNIX, etc.) have their own manuals as
do application software (e.g. word processing and database programs). If you have questions about those programs,
you should consult those manuals.
The notebook is designed to be upgradable. It supports Intel mobile Pentium
™
III and Celeron CPUs of different
speeds and different types of LCD screens: TFT color from a variety of manufacturers and in a variety of resolu-
tion/color configurations. See Chapter 3, “Disassembly,” for a detailed description of the upgrade procedures for
each specific component. In addition, system memory, hard disk, and BIOS are also upgradable.
Please note the warning and safety information indicated by the “M” symbol.
The balance of this chapter reviews the computer’s technical specifications and external features.
