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.
