Some Compaq computers have a complete series of POST error messages that no code
numbers assigned to them. Use the information below for those computers.
An error message results if the Power-On Self-Test (POST) encounters a problem. This
test runs when the system is turned on, checking assemblies within the computer and
reporting any errors found.
POST
checks the following assemblies to ensure that the
computer system is functioning properly:
T
Keyboard
T
System board
T
Memory modules
T
Video memory
T
Diskette drives
T

POST
also detects the type of mass storage devices installed in the computer.
If
POST
finds an error in the system, an error condition is indicated by an audible and/or
visual message. The following table gives explanations of the error codes and
recommended courses of action.
An external speaker must be installed into the speaker output connector to hear
audible beeps during
