Compaq LTE 5200 Personal Computer User Manual


 
This chapter contains typical error messages that you may encounter during
the power-on self-test (POST). POST is a series of tests that run every
time you turn on the computer. POST verifies that the system is configured
and functioning properly. A successful POST is followed by one or two
short beeps.
If you receive an error message listed below, follow the recommended
action. If you receive an error message that is not listed, contact your
Compaq authorized service provider. You may also want to run Computer
Checkup from the Diagnostics diskette. Information about running Computer
Checkup is presented later in this section.
If POST detects an error, one of the following events occurs:
o A message with the prefix "WARNING" appears informing you where the
error occurred. The system pauses until you press F1 to continue.
o A message with the prefix "FATAL" appears informing you where the error
occurred. After the message, the system emits a series of audible beeps.
The system then stops.
o The system emits a series of audible beeps. The system then stops.
Warning messages indicate a potential problem exists such as a system
configuration error. When F1 is pressed, the system should resume. You
should be able to correct problems that produce WARNING messages.
IMPORTANT: When a WARNING message includes the prompt to "RUN SCU," run
Computer Setup. (Computer Setup replaces the SCU utility.)
Fatal errors emit a beep and may display a FATAL message. Fatal errors
indicate severe problems, such as a hardware failure. Fatal errors do not
allow the system to resume. Some of the Fatal error beep codes are listed
at the end of this section.
