Chapter 5 System Troubleshooting
Troubleshooting Procedure
Follow this procedure to identify and isolate a problem with the computer’s
operation.
1. Shut down the computer by using the appropriate method for the installed
operating system.
2. Disconnect power from the computer.
3. Disconnect all peripheral devices from the computer.
4. Connect the keyboard and mouse, if used.
5. Check the video connection if using an external monitor.
6. Connect power to the computer and check the POST.
One of three events will occur:
• The computer completes the start-up process.
• An error message displays to indicate a nonfatal fault. You may have to
acknowledge the message before the start-up process continues.
• The start-up process terminates if a fatal error occurs.
7. If the system starts, isolate the problem by connecting peripheral devices
one at a time until the problem occurs.
If the problem is with a specific software package, or driver, reinstall the
software.
If the problem is not related specifically to a software installation or a
peripheral device, refer to the diagnostic utility and the troubleshooting
checklists.
Diagnostic Utility If you followed the troubleshooting procedure and are still having problems, use
the diagnostic utility to isolate the problem. This utility determines the cause of
the malfunction by testing computer components.
The diagnostic utility and documentation are on the Support CD that ships with
your computer. To run the diagnostic utility, attach an external CD-rom drive
and restart the computer. No software is installed, nor does the utility affect any
software already installed.
You can perform an initial diagnosis without disconnecting or moving your
computer. The process takes as little as five minutes or as long as eight hours,
depending on the tests selected. After the diagnostic utility has run, you can
generate a report for analysis by a technical support representative, expediting any
necessary repair process.
IMPORTANT Before performing any maintenance procedures, review the safety
information in
Hazardous Locations on page 14 for equipment used in
hazardous locations.
