DIAGNOSTICS (DIAGS)
Diagnostic error codes occur if the system recognizes a problem while running the Diagnostics
program.
These error codes help identify possible defective subassemblies.
Tables 3-2 through 3-17 list possible error codes, a description of the error condition, and the
action required to resolve the error condition.
In each case, the Recommended Action column lists the steps necessary to correct the problem.
After completing each step, run the Diagnostics program to verify whether the error condition has
been corrected.
If the error code reappears, perform the next step, then run the Diagnostics
program again.
Follow this procedure until the Diagnostics program no longer detects an error
condition.
If you encounter an error condition, complete the following steps before starting problem isolation
procedures:
1.
Ensure that there is proper ventilation.
The computer should have approximately 12 inches
(30.5 cm) clearance at the front and back of the system unit.
2.
Turn off the computer and peripheral devices.
3.
Disconnect any peripheral devices other than the monitor and keyboard.
Do not disconnect
the printer if you want to test it or use it to log error messages.
4.
Delete the power-on password, if set.
You will know that the power-on password is set when
a key icon appears on the screen when POST completes.
If this occurs, you must enter the
password to continue.
To delete the password, type the current password and press the
Enter
key.
5.
If you do not have access to the password, you must disable the power-on password by using
the Password Disable switch on the system board.
6.
Install a loopback plug when instructed to by Diagnostics (Part Number 142054-001).
7.
Run the latest version of Diagnostics.
