							Chapter 2.5 Compaq Diagnostics 
A Compaq Diagnostics diskette is supplied with the computer. Run the
Diagnostics utilities when you want to view or test system information and
installed or connected devices. The Diagnostics menu includes the
following utilities:
o Computer Checkup (TEST)
o View System Information (INSPECT)
If you have a problem you cannot solve, run the Diagnostics utilities
before you call for support. Run Computer Checkup and select to save the
device list to a file and to print or to save the log of errors. Run the
View System Information (INSPECT) utility and select to print or to save
that information. Have the files or the printed information available when
you call for support.
2.5.1 Computer Checkup (TEST)
Computer Checkup (TEST) determines whether the various computer components
and devices are recognized by the system and are functioning properly. You
can display, print, or save the information generated by Computer Checkup.
Follow these steps to run Computer Checkup:
1. Plug the computer into an external power source. (A low battery
condition could interrupt the program.)
2. Turn on the external devices that you want to test. Connect the
printer if you want to print a log of error messages.
3. Insert the Compaq Diagnostics diskette in drive A.
4. Turn on or restart the computer. The computer starts from drive A, and
the Diagnostics Welcome screen appears.
5. Press Enter to continue. The Diagnostics menu appears.
6. Select Computer Checkup from the Diagnostics menu. A Test Option menu
appears.
7. Select View the Device List from the Test Option menu. A list of the
installed Compaq devices appears.
8. If the list of installed devices is correct, select OK. The Test
Option menu appears.
NOTE: If the list is incorrect, ensure that any new devices are
installed properly. 
						

							9. Select one of the following from the Test Option menu:
o Quick Check Diagnostics. Runs a quick, general test on each device
with a minimal number of prompts. If errors occur, they display when
the testing is complete. You cannot print or save the error
messages.
o Automatic Diagnostics. Runs unattended, maximum testing of each
device with minimal prompts. You can choose how many times to run
the tests, to stop on errors, or to print or save a log of errors.
o Prompted Diagnostics. Allows maximum control over testing the
devices. You can choose attended or unattended testing, decide to
stop on errors, or choose to print or save a log of errors.
10. Follow the instructions on the screen as the devices are tested. When
testing is complete, the Test Option menu appears.
11. Exit the Test Option menu.
12. Exit the Diagnostics menu.
2.5.2 View System Information (INSPECT)
The View System Information (INSPECT) utility provides information about
the computer and installed or connected devices. You can display, print,
or save the information.
Follow these steps to run View System Information (INSPECT) from the
Compaq Diagnostics diskette:
1. Turn on the external devices that you want to test. Connect the printer
if you want to print the information.
2. Insert the Compaq Diagnostics diskette in drive A.
3. Turn on or restart the computer. The computer starts from drive A, and
the Diagnostics Welcome screen appears.
4. Press Enter to continue. The Diagnostics menu appears.
5. Select View System Information (INSPECT) from the Diagnostics menu.
6. Select the item you want to view from the following list:
===========================================================================
System Memory
ROM Audio
Keyboard Operating system
System ports System files
System storage Windows files 
						

							Graphics
===========================================================================
7. Follow the instructions on the screen to cycle through the screens, to
return to the list and choose another item, or to print the
information.
Chapter 2.6 Diagnostic Error Codes 
Diagnostic error codes occur if the system recognizes a problem while
running the Compaq Diagnostic program. These error codes help identify
possibly defective subassemblies.
Tables 2-4 through 2-16 list possible error codes, a description of the
error condition, and the action required to resolve the error condition.
IMPORTANT: Retest the system after completing each step. If the problem
has been resolved, do not proceed with the remaining steps.
For assistance in the removal and replacement of a particular subassembly,
see Chapter 5, Removal and Replacement Procedures.
