other LED error codes. Contact HP for assistance. See
BIOS authentication failure
The BIOS authentication error (Blink code 6) is extremely rare. It is the result of a discrepancy
between the BIOS and the hardware that is installed on the computer. This error occurs when
the BIOS cannot authenticate signatures from the hardware on the system. The purpose of the
BIOS authentication is to be sure that no one has tampered with the BIOS on the computer.
If a BIOS authentication failure occurs, the computer automatically performs a BIOS recovery.
If the computer does not automatically recover the BIOS, contact HP for assistance. See
