1: Introduction
Overview
This manual covers the information you need to service or upgrade the 8880 series notebook computer. Information
about operating the computer (e.g. getting started, and the Setup utility) is in the User’s Manual. Information about driv-
ers (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, Windows XP, OS/2 Warp, 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 8880 series notebook is designed to be upgradeable. See “Disassembly” on page 2 - 1 for a detailed description of
the upgrade procedures for each specific component. Please note the warning and safety information indicated by the
“” symbol.
The balance of this chapter reviews the computer’s technical specifications and features.
