Hard drive is about to
fail. (Some hard drives
have a firmware patch
that will fix an erroneous
error message.)
One or more SATA
devices are improperly
attached. For optimal
performance, the SATA 0
and SATA 1 connectors
must be used before
SATA 2 and SATA 3.
Drivelock is enabled on
one or more SATA hard
drives, and they cannot
be accessed while the
system is configured for
RAID mode.
Processor not supported
by ROM BIOS.
Electronic serial number
has become corrupted.
Parity RAM failure.
Third-party graphics
cards may be causing a
problem

Recommended Action
1. Determine if hard drive is giving
correct error message. Enter
Computer Setup and run the Drive
Protection System test under
Storage > DPS Self-test.
2. Apply firmware patch if applicable
(available at www.hp.com/support).
3. Back up contents and replace hard
drive.
Ensure SATA connectors are used in
ascending order. For one device, use
SATA 0. For two devices, use SATA 0
and SATA 1. For three devices, use SATA
0, SATA1, and SATA 2.
Either remove the Drivelocked SATA
device or disable the Drivelock feature.
To disable the Drivelock feature, enter
Computer Setup, change Storage >
Storage Options > SATA
Emulation to IDE, and select File >
Save Changes and Exit. Reenter
Computer Setup and select Security >
Drivelock. For each listed
Drivelock-capable SATA device, ensure
Drivelock is Disabled. Lastly, change
Storage > Storage Options >
SATA Emulation back to RAID and
select File > Save Changes and
Exit.
1. Upgrade BIOS to proper version.
2. Change the processor.
1. Run Computer Setup. If Setup
already has data in the field or will
not allow the serial number to be
entered, download the executable
file from http://www.hp.com.
2. Run Computer Setup and try to enter
serial number under Security, System
ID, then save changes.
Run Computer Setup and Diagnostics
utilities.
Remove third-party graphics card to see
if the problem goes away.
