This section provides a procedure for troubleshooting the ports on the computer’s I/O
panel and the equipment connected to them, such as a printer, scanner, or other
peripheral device.
You can also use this procedure to test I/O ports on expansion cards. However, you
should first complete the procedures in “Troubleshooting Expansion Cards” in Chap-
ter 7 to verify that the card is configured and installed correctly.
If a system error message indicates a port problem or if equipment connected to a
port seems to perform incorrectly or not at all, the problem may stem from any of the
following sources:
‡
A faulty connection between the I/O port and the peripheral device
‡
A faulty cable between the I/O port and the peripheral device
‡
A faulty peripheral device
‡
Incorrect settings in the System Setup program
‡
Incorrect settings in the system’s configuration files
‡
Faulty I/O port logic on the system board
NOTE: With certain modems installed, subtests in the Serial Port test group may fail
because the modem appears to the diagnostics as a serial port but it cannot be tested
as a serial port. If you have a modem installed and you experience a serial-port test
failure, remove the modem and run the diagnostic tests again.

This procedure determines whether the computer’s basic I/O functions are opera-
tional. If a system error message indicates an I/O port problem or the device
connected to the port does not function properly, follow these steps:
1. Enter the System Setup program, and check the Serial Port 1 , Serial Port 2 , Par-
allel Port , and Mouse settings.
Are the communications ports set to Auto , and is Mouse set to On ?
Yes. Go to step 3.
No. Go to step 2.
2. Change the Serial Port 1 , Serial Port 2 , and Parallel Port settings to Auto , and
change the Mouse setting to On ; then reboot the system.
Is the problem resolved?
Yes. You have fixed the problem.
No.
Go to step 3.
