This maintenance information manual, SY31-0405, is
intended
to
be used
for
servicing the IBM 5100 Portable
Computer. Service personnel using this manual are
assumed
to
have completed the IBM 5100 training
course.
To service the
IBM
5100 Portable Computer, use this
manual
with
the MAPs (maintenance analysis
procedures) provided.
It
is important
that
you begin
your call
with
the start
MAP
that
leads you
to
other
MAPs and eventually
to
the failing
FRU
(field
replaceable unit).
This manual contains six major sections:
• Using the Maintenance Library: Contains instructions
and examples
for
using the MAPs
to
diagnose
machine problems, and further introduces this
maintenance information manual.
• Maintenance: Contains location drawings,
maintenance procedures, and graphics
for
each
functional unit within the 5100 Portable Computer.
Each
drawing, procedure, or graphic has a three digit
reference number assigned
to
it
for
referencing
from
the MAPs.
• Diagnostic Aids: Contains diagnostic information
that
enables service personnel
to
further define failures
not
found by the MAPs.
• Theory: Contains detailed information about the
individual functional units
within
the 5100. This
information contains operational details
for
further
defining failures when the MAPs do not find the
cause
of
the failure.
• Circuits: Contains high level logics, wiring diagrams,
and cable charts
to
enable service personnel
to
understand specific details
of
the 5100 functional
units.
• Language Support: Contains APL and BASIC
language support reference information,
which
is
necessary
to
determine
if
failures are associated
with
the
5100 internal microprograms.
