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. Table 7-7 Boot-error codes Blink codes Error Amber battery light: blinks 1 Hz continuously Embedded Controller unable to load firmware Caps/num lock lights = 1 blink Processor not executing code Caps/num lock lights = 2 blinks BIOS recovery code unable to find valid BIOS recovery image Caps/num lock lights = 3 blinks Memory module error Caps/num lock lights = 4 blinks Graphics controller error Caps/num lock lights = 5 blinks System board error Caps/num lock lights = 6 blinks Intel Trusted Execution Technology (TXT) Error Caps/num lock lights = 7 blinks Sure Start unable to find valid BIOS Boot Block image Caps/num lock lights = 8 blinks Sure Start has identified a problem (Manual Recovery Policy Set) 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 90. 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 "Off" 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. BIOS recovery code unable to find valid BIOS recovery image This computer has experienced a problem in locating a valid BIOS image, resulting in a failed startup. This problem may be resolved by placing a clean copy of the system BIOS on a USB key or in the appropriate hard drive directory and performing a reboot. If this error reoccurs, refer to General troubleshooting steps on page 90. 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 "Off" or "Hibernated" state, lights associated with the caps lock and num lock keys will both blink twice followed by a pause, and then continue in a repeating pattern. Memory module error This computer has experienced a memory initialization problem resulting in a failed startup. This issue may be related to the memory modules in the computer. This problem may be resolved by ensuring that memory modules are correctly inserted and seated. If this error reoccurs, a service event is required to determine the source of the error (memory modules or system board) and take the appropriate corrective action. 150 Chapter 7 Troubleshooting guide

Blinking lights and boot error codes
The information below is from the white paper
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.
Table 7-7
Boot-error codes
Blink codes
Error
Amber battery light: blinks 1 Hz continuously

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

.
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
“Off”
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.
BIOS recovery code unable to
find
valid BIOS recovery image
This computer has experienced a problem in locating a valid BIOS image, resulting in a failed startup. This
problem may be resolved by placing a clean copy of the system BIOS on a USB key or in the appropriate hard
drive directory and performing a reboot. If this error reoccurs, refer to
