Operating Requirements
All machines requ ir e two power inputs: one for the
system unit and one for the monitor display.
The system unit comes with a volt age sel ec tor s witch,
allowing selection of voltage of eith er 115 Vac or 230
Vac. This switch must be in the 230 Va c p osition
when the machine is plugged into a 230 Vac electrical
outlet.
The required power input for the monitor (Not
included with some models) shipped with the system
unit is auto-sensing type and does not require any
voltage switch adjustment.

check procedure, proceed to t hat section. If there are
any notes or instructions at the top of the page, read
them before you begin with the procedure. Carefully
read each step of the check procedure and perform
the steps as inst ructed. If you do not remember the
location of a specific part or test point, or an
adjustment or remo val procedure, see the chap ter
that contains that inf ormation. Always return to the

Start
This is the entry point for all check procedur es. The
check procedures use failure symptoms , Power-On
Self Test (POST) error codes, or beeps to help
determine the defective field replac eable unit (FRU).
Follow the suggested check procedures or use the
diagnostic s dis kette to determine the problem FRU.
IMPORTANT:
determined that the error is not a result of
software, loo se contacts, or dirty component
surfaces. Any FRU change should be verified
by running a complete test (“Diagnostics - All
Tests” in PC-Doctor diagnostics program).
This book comes with a dia gnostic program disket te.
This diskette should be used ONLY with
6833
IBM Personal Computers. Do not use this
diskette on oth er models.
POST error codes and error messages are displayed
on the screen after the IBM logo. Meanwhile, error
beeps could be issued to help diagnose syste m
problem. Please refer to “Index of Symptoms,
Messages, Error Codes, or Beeps” on page 32 for
additional help.
All voltages in the check procedures are positive
unless otherwise indicated. Use frame ground for all
voltage checks unless otherwise specified.
NOTE:
a FRU and the error message persists, an
option adapter card might be causing the
failure. Remove all option adapter cards, one
at a time, until the error changes or the
problem is no longer apparent. Replace the
last option adapter card removed.
The hard disk drive contains pre-loaded software. Be
sure to reload the software on the primary hard disk
drive (Drive C) when replacing it.
IMPORTANT:
servicing may have been rearranged, or the
drive startup sequence has changed. Be
extremely careful during write operations, such
as copying, savi ng, or formatting. Data or
programs can be overwri tt en if you select an
incorrect drive.
Replace FRUs ONLY when it is
6832 and

any additional softwar e from the hard disk
drive before you reload the software.
How to Diagnose Combin ed FRUs: If an adapter or
device consist s of more than one FRU, any of the
FRUs might cause an error code. Before replacing
the device or adapter, remove the FRUs one by one
to see if the sympto ms change.
If a newly replaced FRU does not correct the
problem: If you have reached this point of the check
procedures and were instructed to replace a FRU but
doing so did not correct the problem, reinstall the
original FRU and go throug h “Start” again.
If you want to print a copy of a Configuration/Setup
Utility screen to an attached printer, press Print
Screen key while the following screen is displayed.
READ THE FOLLOWING:
Human Error is a cause for concern when applie d
to check procedures. It exists in every first time
set of analysis proc edures. It is therefore
essential f or effective and time-efficie nt servicing
that each stage of every procedure be verified.
(For example: When a sym ptom is f ound, or when
a symptom appears to have been cur ed; the
preceding steps shoul d be repeated for accuracy
of analysis.)

How to Use Error Messages:
error codes, and beeps combinations tha t occur to
diagnose failures. If more than one failure occurs,
begin the diagnosis from the first failure that
appeared. The cause of the first failure can re sult in
false messages, error codes, or beeps. If you did not
receive any messages, error codes, or beeps, see if
the symptom is listed in “Table 2-3 Error Symptoms
List” on page 38.

POST:
machine, such as the Power-On Self Te st (POST).
The machine performs the POST each time it is
powered on. Use this inf ormation throughout the
diagnostic procedures. The POST is a series of
system checks and initializations that verify the
correct operation of the base system.
When you have deemed it necessary to
replace a FRU, and have done so, you must
run a total system check to ensure that no
other acti vity has been affected by the change.
This system check can be done through the
diagnostics program (Select Diagnostics, then
select and execute All Tests from PC-Doctor).
Some diagnostic aids are resident in the
Use the messages,
After a successful POST, the system attempts to load
the operati ng system. The sys tem can be cust omi zed
for different startup (boot) met hods by the BIOS
Configuration/Setup Utility. See “BIOS Configurat ion/
Setup Utility” on page 12.
The system's default startup sequence automatically
looks for the operating system files in the hard disk if
these files are not found in the diskette.

Troubleshooting
Failing Part s or Assem blies:
generally help you trace a problem to one part or
assembly. The last step of the specific check
procedure you are usi ng indicates that a part or
assembly is fai li ng. You should inspect the part or
assembly before you decide to replace it. It might be
loose, dirty, or in need of a small repair. The check
procedures might lead you to two, or even three,
possible failing parts or assemblies. The parts that
might be failing are listed in order of the most
probable failure. Also, the FRU parts are defined as
replaced units and are not repaired in the fie ld.
Measuring Voltages:
instruct you to measure voltages on cable pl ugs and
electronic board connectors. If you are asked to
measure voltage at several places on a plug or
connector, a chart next to or near the instruction
indicates the numb er of the plug or connect or , the pin
numbers you should measure, the signal name, and
the correct voltage for the condition you are
measuring. Measure the voltage only at the pi ns
listed in the chart. Remember to set the meter on the
correct scale and to put the meter leads in the correct
position fo r the voltage you are asked to measur e.
NOTE:
Use frame ground as the groun d reference.
Attach the black (ground) lead of meter to
frame ground, except where specified
otherwise.
