Undetermined Problem
Use the following procedure when the diagnostic tests do
not identify the failing adapter or device.
Check that all cables, wires, and connectors are connected
so that they do not cause a short circuit. If any problems
are found, reconnect or replace them.
Check the power supply for correct operation (see “Power
Systems Checkout” on page 346). If the power supply is
operating correctly, return here and continue with the
following procedures.
1. Power-off the computer.
2. Remove or disconnect one at a time the following
adapters or devices from the Dock I. (Do not isolate
adapters or devices that are known to be good.)
a. Non-IBM devices.
b. A modem, printer, mouse, external keyboard,
external display, external diskette drive, numeric
keypad, or other external devices.
c. Any adapter.
Note: Removing an adapter or device might
cause configuration errors. Ignore error
code 174.
d. SCSI device.
e. Hard disk drive.
3. Power-on the system and check if the problem has
changed.
4. If the symptom remains, repeat Steps 1 through 3
until you find the failing adapter or device, or until all
adapters or devices have been removed.
5. If all adapters or devices have been removed and the
problem remains, replace the following Dock I FRUs
one at a time.
Note: If a replaced part did not resolve the problem,
put the original part back in the Dock I. Do
not replace non-defective parts.
a. I/O card
b. Main board
c. Dock I audio card
If the problem goes away when you remove an adapter,
but replacing the adapter does not correct the problem,
replace the main board of the Dock I.
