The Advanced Diagnostics program is shipped on the
hard disk drive. An external diskette drive must be
attached to the computer to run the diagnostics
program from a diskette. The Advanced Diagnostics
diskette, part number S83G8095, contains the same
Advanced Diagnostics program shipped on the hard
disk drive. If the diagnostics are not on the hard disk
drive and an external diskette drive is not attached to
the computer, do the following.
1. Run the POST (Power-On Self Test).
2. If you receive an error, go to “Symptom-to-FRU
Index” on page 264.
3. If you suspect an undetermined problem, go to
“Undetermined Problems” on page 267.
1. Power-off the computer and all external devices.
2. Check all cables and power cords for correct
connection.
3. If you are going to run the advanced diagnostics from
the diskette drive; insert the Advanced Diagnostics
diskette into the diskette drive, then continue with
step 4
If you are going to run advanced diagnostics from the
hard disk drive, go to step 6.
4. Power-on all external devices.
5. Power-on the computer and check for one short beep
at the end of POST with a clear and readable
diagnostics menu displayed.
If you did not get the correct responses, go to
“Symptom-to-FRU Index” on page 264.
If you received the correct responses, go to step 12
on page 259.
6. Power-on all external devices.
7. Power-on the computer and check for one short beep
at the end of POST with a clear and readable
diagnostics menu displayed. If you did not get the
correct responses, go to “Symptom-to-FRU Index” on
page 264.
Note: The following two steps are important because
they prevent programs which might affect the
diagnostic tests from being loaded into
memory.
8. When the message Starting PC DOS appears,
press F5.
9. When the DOS prompt appears, type
cd c:\thinkpad\diags
