The
IBM
5100
Portable
Computer
Maintenance Library
consists
of
MAPs
(maintenance
analysis
procedures).
a
maintenance
information
manual, and parts catalog.
The
MAPs and
the
maintenance
information
manual are
unique
maintenance
documents
and are,
therefore,
covered
in
this
description.
The
MAPs are
EC
controlled
and
will be
updated
as
necessary
to
provide
you
with
the
latest
information
possible
to
diag-
nose
5100 Portable
Computer
problems.
The
maintenance
information
manual will be
updated
simultaneously
with
the
MAPs using TN
Ls
and
revisions. It
is
important
that
the
MAPs
and
maintenance
information
be
at
compatible
levels.
MAPs
The
MAPs guide
you
through
the
service call using step-by-
step
procedures
that
require
you
to
follow
trace
lines
when
responding
to
questions
or
when
leaving
or
entering
a page.
The
MAPs use a logical
approach
for isolating
the
possible
causes
of
machine
problems
and
point
you
to
that
part
of
the
5100 Portable
Computer
that
requires
adjustment
or
re-
placement.
Two
types
of
MAPs are used
in
the
IBM
5100
Portable
Com-
puter
Maintenance Library. First,
there
are
the
hard
copy
(printed) MAPs
within
the
MLM
binder. These MAPs are
contained
in a
separate
removable binder.
The
second
type
is
MOl
(maintenance
and
diagnostics
integrated)
and
is
located
on
the
diagnostic
tape
cartridge.
These MAPs are
shown
on
the
display screen. Paging
through
these MAPs
is
accomplished
automatically
when
you
respond
to
the
questions
on
the
display.
MAP
ORGANIZATION
Start
MAP
This
is
the
starting
point
for
each service call.
From
here
you
will be guided
to
the
failing
FRU
(field replaceable unit) in
the
5100
Portable
Computer
or
to
other
MAPs
that
further
identify
the
problem.

Maintenance Library
Bring Up
and
Process Check MAPs
The
start
MAP
sends
you
to
the
bring
up
or
process check
MAPs
when
the
5100 Portable
Computer
fails
to
become
REAOY
or
when
the
PROCESS CHECK light
is
on.
Control
unit failures are generally
found
by these MAPs.
IBM
5100
Portable
Computer
Device MAPs
These MAPs find failures in
the
5100
Portable
Computer
basic devices. When a failure occurs
in
the
keyboard,
dis-
play,
tape,
or
power
supply,
the
start
MAP sends
you
directly
to
that
device MAP
to
find
the
failing
FRU.
When multiple
symptoms
are
present
and
the
PROCESS
CHECK light
is
one
of
them,
always give
priority
to
the
PROCESS CHECK light.
IBM
5103
Printer Device MAPs
These MAPs provide
instructions
on
how
to
load
the
MOl for
the
printer.
The
start
MAP
directs
you
to
this
MAP.
IBM
5106
Auxiliary
Tape
Unit Device MAPs
These MAPs provide
instructions
on
how
to
load
the
MOl
for
the
auxiliary
tape
unit.
The
start
MAP directs
you
here.
MOl MAPs
MOl
MAPs are read
from
the
display screen. These MAPs
can be used
only
when
the
5100 Portable
Computer
basic
functions
are
operational.
The
5100
features
(printer,
communications
adapter/serial I/O
adapter,
and
auxiliary
tape)
and
the
tape
write
function
use
this
MAP
technique.
A description
of
MOl
and
how
to
use
it
is
found
in
the
Diagnostic
Aids
section._
Machine
Checkout
The
start
MAP
directs
you
to
the
machine
checkout
MAP
to
further
define
5100
Portable
Computer
failures.
Once
the
failure
is
isolated,
you
are
directed
to
other
MAPs
to
locate
the
failing
FRU.
