Power-On Self-Test (POST)

POST is a series of diagnostic tests that run automatically on Compaq computers when the
system is turned on. POST checks the following assemblies to ensure that the computer system is
functioning properly:
Processors
Keyboard
Power supply
System board
Memory
Memory expansion boards
Controllers
Diskette drives
Hard drives

POST Error Messages

If POST finds an error in the system, an error condition is indicated by an audible and/or visual
message. If an error code displays on the screen during POST or after resetting the system,
follow the instructions in Table 3-1. The error messages and codes listed in Table 3-1 include all
codes generated by Compaq products. Your system generates only those codes that are
applicable to your configuration and options.
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 Diagnostics no longer detects an error condition.
