External Components: Dell Precision™ WorkStation 220 System User's Guide
This section provides troubleshooting procedures for equipment that connects directly
to the input/output (I/O) panel of your computer, such as your monitor, keyboard, mouse,
or printer. Before performing any of the procedures in this section, see "Checking Connections and Switches."
Then perform the troubleshooting procedures for the equipment that is malfunctioning.
You need a copy of the Dell Precision ResourceCD to perform the procedures in
this section.
Troubleshooting video problems involves determining which of the following is the
source of the problem:
- Monitor or monitor interface cable
The procedures in this section troubleshoot problems with the monitor and the monitor
interface cable only.
If information on the monitor screen is displayed incorrectly or not at all, perform
each of the following steps in the order indicated until the problem is resolved:
- Turn on the system, including any attached peripherals.
- Adjust the switches and controls as specified in the monitor's documentation to correct
the video image, including the horizontal and vertical position and size.
- Insert the Dell Precision ResourceCD into the CD-ROM drive, reboot the system,
and run the Video test group in the Dell Diagnostics.
- Turn off the system and disconnect it from the electrical outlet. Swap the monitor with
one of the same type that is working, and reconnect the system to an electrical outlet.
- Reboot the system, and run the Video test group again.
If the tests
complete successfully, the original monitor was faulty. If the tests still fail, the video
controller on the system board may be faulty. See "Getting Help" for instructions on obtaining technical assistance.
This procedure determines what kind of keyboard problem you have. If a system error
message indicates a keyboard problem when you start the computer system or if the keyboard
does not operate as expected, perform the following steps in the order indicated until the
problem is resolved:
- If the keyboard or its cable shows signs of physical damage or if the keys do not work,
replace the keyboard with a working keyboard.
- Insert the Dell Precision ResourceCD into the CD-ROM drive, reboot the system,
and run the Keyboard test group in the Dell
Diagnostics.
- If the Keyboard Interactive Test fails, replace the keyboard.
- If the Keyboard Controller Test fails, the system board may be faulty.
See "Getting Help" for instructions on obtaining
technical assistance.
This procedure determines what kind of mouse problem you have. If a system error
message indicates a mouse problem when you start the computer system or if the mouse does
not operate as expected, perform the following steps in the order indicated until the
problem is resolved:
- Clean the mouse as instructed in your mouse documentation.
Most mice have a ball that
can be removed and cleaned of debris by turning the mouse upside down and removing a cover
on the bottom of the mouse. Also remove any lint or other debris that has accumulated on
the bottom of the mouse.
- If the mouse or its cable shows signs of physical damage or if the buttons do not work,
replace the mouse with a working mouse.
- Insert the Dell Precision ResourceCD into the CD-ROM drive, reboot the system,
and run the Mouse Test in the Dell Diagnostics.
- If the Mouse Test fails, the system board may be faulty. See "Getting Help" for instructions on obtaining technical
assistance.
This section provides a procedure for troubleshooting the ports on your 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"
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 source of the problem may be any of the
following:
- 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's configuration files
- Faulty I/O port logic on the system board
 |
NOTE: With certain modems installed,
the Serial Port test group subtests 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. |
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 in the order indicated until the
problem is resolved:
- Enter System
Setup and verify that the settings for the Serial Port 1, Serial Port 2,
and Parallel Port options are set to Auto.
- Insert the Dell Precision ResourceCD into the CD-ROM drive, reboot the system,
and run the Serial/ Infrared Ports test group and/or the Parallel
Ports test group in the Dell
Diagnostics.
If any of the tests fail, the system board may be faulty. See "Getting Help" for instructions on obtaining
technical assistance.
If the problem persists, go to "Troubleshooting a Parallel Printer" or "Troubleshooting a Serial I/O
Device," depending on which device appears to be malfunctioning.
If the information in " Troubleshooting Basic I/O Functions"
indicates that the problem is with a parallel printer, perform the following steps in the
order indicated until the problem is resolved:
- Reinstall the printer device driver.
See the documentation for the printer and for
your operating system for instructions on reinstalling the printer driver.
- Turn off the parallel printer and computer, replace the parallel printer interface cable
with a known working cable, and turn on the parallel printer and computer.
If the problem is resolved, the original printer cable was faulty.
- Run the parallel printer's self-test.
If the test fails, the printer is faulty.
If the problem still is not resolved, the system board may be faulty. See " Getting Help" for instructions on obtaining
technical assistance.
If the information in "Troubleshooting Basic I/O Functions"
indicates that the problem is with a device connected to one of the serial ports, perform
the following steps in the order indicated until the problem is resolved:
- Attach the serial device to the other serial port (for example, if it is currently
connected to serial port 1, attach the device to serial port 2).
If the problem is
resolved, the serial port on the system board is faulty. See "Getting Help" for instructions on obtaining
technical assistance.
- If the faulty device has a detachable serial cable, replace the serial cable.
If the
problem is resolved, the serial cable was faulty.
- Replace the faulty serial device.
If the problem is still not resolved, the system board may be faulty. See "Getting Help" for instructions on obtaining
technical assistance.
