2.3 Computer Checkup (Test)  
After POST runs successfully, run the latest version of Computer Checkup 
(TEST). Computer Checkup determines if the computer assemblies and options 
are recognized by the system and functioning properly. Run Computer Checkup 
after installing or connecting a new assembly or option. 
Computer Checkup is installed on the hard drive. If the hard drive is not 
functioning, you can run it from the Compaq Diagnostics diskette by 
inserting the diskette in Drive A before turning on the computer. 
NOTE: It is recommended that you make a diskette copy of Compaq Diagnostics
and keep it available for future need. If necessary, a copy can be 
obtained from the Compaq Customer Support Center.
Running Computer Checkup 
To run Computer Checkup from the hard drive, complete the following steps: 1. Turn off the computer. 
2. Turn on the computer. 
3. Press F10 immediately after the computer beeps and the cursor moves to the upper-right corner of the screen. 
						

							The Configuration and Diagnostics menu is displayed.
4. Select Computer Checkup (TEST) from the Configuration and Diagnostics
menu.
The Computer Checkup options menu is displayed.
5. Select View Device List.
A list of the installed hardware devices is displayed.
NOTE: Computer Checkup may not detect non-Compaq devices.
6. Verify that Computer Checkup correctly detected the installed devices.
If the list is correct, select OK. The Computer Checkup option menu is
displayed again.
If the list is incorrect, verify that the new devices are installed
properly.
7. Select one of the following from the Computer Checkup options menu:
o Quick Check Diagnostics - This option runs a quick, general test on
each device with a minimal number of prompts. If errors occur, they
are displayed when the testing is complete.
o Automatic Diagnostics - This option runs an unattended, maximum test
of each device with minimal prompts. You can choose how many times to
run the tests, to stop on errors, or to print or file a log of
errors.
o Prompted Diagnostics - This option allows maximum control over the
device testing process. You can choose attended or unattended
testing, decide to stop on errors, or choose to print or file a log
of errors.
8. Follow the instructions on the screen as the diagnostic tests are run
on the devices.
When the testing is complete, the Computer Checkup options menu is
displayed again.
9. Exit the test option menu.
10. Exit the Configuration and Diagnostics menu.
NOTE: Exiting the Configuration and Diagnostics menu restarts the
computer and saves your changes.
11. Look up in the Computer Checkup Error Codes tables any error codes
that were displayed, and take the recommended action. 
						

							12. Rerun POST and Computer Checkup, completing the recommended actions in
the order given until the problem is solved and no error messages
occur.
Computer Checkup (TEST) Error Codes
Computer Checkup (TEST) error codes occur if the system recognizes a
problem while running Computer Checkup. These error codes help identify
possible defective assemblies. Tables 2-2 through 2-13 list Computer
Checkup error codes, a description of the error condition, and the
recommended action for resolving the condition.
NOTE: The error codes in the following tables are listed in an AYY-XX
format, where:
A or AA = Number that represents the faulty assembly.
YY = Test or action that failed.
XX = Specific problem.
