POST ERROR MESSAGES - NOT NUMBERED

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￿Hard drive

T￿Power supply

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 POST.
