I have two Compaq Professional Workstations that won't turn post and blink out led error codes compaq and hp have no information on:
SP700 (fans turn on and drives spin up, but no post and power led rapidly blinks green)
SP750 (no response from system on push of power button power led blinks green once then proceeds to slwly blink amber. Also this perticular has a motherboard power light that is lit on the mainboard and also appears to have an error led on the board as well that is not lit up)
Everything has been reseated properly in all systems, contacts cleaned and all extra components (drives and cards have been removed from both systems)
The only information i was able to find states solid amber for a malseated daughterboard, and blinking green every second for standby but no other information. Unfortunately hp appears to have gotten rid of much of the troubleshooting information for these systems. From what I've found out about how these systems function is they boot into a prebios diagnostics that display errors of some of the subsystems via the power led.
Thanks for the help
