Undetermined Problems
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
Supply” on page 626). If the power supply is operating
correctly, return here and continue with the following
procedure:
1. Turn off the computer.
2. Remove or disconnect the following adapters or
devices one at a time from the SelectaDock Docking
System. (Do not isolate adapters or devices that are
known to be good.)
a. Non-IBM devices.
b. A modem, printer, mouse, external keyboard,
external monitor, external diskette drive, numeric
keypad, USB device, or other external devices.
c. Any adapter.
d. SCSI device.
e. Hard disk drive.
3. Turn 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 card or device, or
until all adapter cards or devices have been removed.
5. If all adapters or devices have been removed and the
problem remains, replace the following the
SelectaDock III FRUs one at a time.
Note: If a replaced part did not resolve the problem,
put the original part back in the SelectaDock
III. Do not replace nondefective parts.
a. Riser card.
b. Main card.
c. Audio card.
d. USB card.
If the problem goes away when you remove an adapter
card, but replacing the adapter card does not correct the
problem, replace the main card.
