NBLB2 Service Manual

Testing and Troubleshooting
The purpose of this chapter is to provide a systematic method of isolating problems
you may have with the NBLB2 series Notebook Computer. We assume that you have
a basic understanding of DOS-based computer systems as well as knowledge of
standard troubleshooting procedures. This manual is written under the assumption
that the problems are indeed related with Notebook itself. The improper usage and
application software problems are excluded in this chapter. The system BIOS Beep
Code is an integrated unit to detect some errors in the system board. This beep code
will give immediate identification of certain system board problems. If the
troubleshooting procedure is followed step by step, it can efficiently isolate the
problem and the problem can be solved easily.
