Blinking lights and boot error codes
The information below is from the white paper http://h10032.www1.hp.com/ctg/Manual/c04685655.
In some cases, when the host processor is not executing code or does not have the necessary code to drive the
display, light blink codes inform you of a problem.

Processor not executing code
This computer has experienced a problem due to the failure of certain code to execute, resulting in a failed
startup of the processor. The issue could be related to the processor or the system board in the computer. If the
processor is socketed, be sure that the processor is seated correctly in the socket. If this error reoccurs, refer to
General troubleshooting steps on page 59.
NOTE: The computer will attempt to notify you of this problem through a series of blinking lights. When you
attempt to turn on the computer from an “O” or “Hibernated” state, lights associated with the caps lock and
num lock keys will both blink once followed by a pause, and then continue in a repeating pattern.
