CAUTION: Only authorized technicians trained by HP should
attempt to remove the system board. If you believe the system board
requires replacement, contact HP Technical Support before proceeding.
If the system fails in this minimum configuration, one of the primary
components has failed. If you have already verified that the processor,
PPM, power supply, and memory are working before getting to this
point, replace the system board. If not, be sure each of those components
is working.
