							7Statement of Volatility
The purpose of this document is to provide general information regarding non-volatile memory in industry-standards based HP Business Notebook PC systems and provide general instructions for 
restoring nonvolatile memory that can contain personal data after the system has been powered off 
and the hard drive has been removed.
HP Business Notebook PC products that use Intel-based or AMD®-based system boards contain 
volatile DDR memory. The amount of nonvolatile memory present in the system depends upon the 
system configuration. Intel-based and AMD-based system boards contain nonvolatile memory 
subcomponents as originally shipped from HP assuming that no subsequent modifications have been 
made to the system and assuming that no applications, features, or functionality have been added to 
or installed on the system.
Following system shutdown and removal of all power sources from an HP Business Notebook PC 
system, personal data can remain on volatile system memory (DIMMs) for a finite period of time and 
will also remain in nonvolatile memory. The steps below will remove personal data from the notebook 
PC, including the nonvolatile memory found in Intel-based and AMD-based system boards. Some of 
these steps are disclosed in the Maintenance and Service Guides available for HP PC products 
available on the product support pages at www.hp.com.
1.Follow steps (a) through (I) below to restore the nonvolatile memory that can contain personal 
data. Restoring or re-programming nonvolatile memory that does not store personal data is 
neither necessary nor recommended.
a.Enter BIOS (F10) Setup by powering on the system and pressing F10 when prompted near 
the bottom of the display, or press the 
ESC key to display the start up menu, then press 
F10 . If the system has a BIOS administrator password, enter the password at the prompt.
b.Select the File menu, then Restore Defaults.
c.Select the System Configuration menu, then Restore Security Defaults.
d.If an asset or ownership tag is set, select the Security menu and scroll down to the Utilities 
menu. Select System IDs, and then select the tag that has been set. Press the spacebar 
once to clear the tag, then press 
Enter to return to the prior menu.
e.If a DriveLock password is set, select the Security menu, scroll down to DriveLock, then 
select 
DriveLock password. Select the desired hard drive. Click Disable protection, enter 
the existing master DriveLock password, then press 
Enter to confirm and return to the prior 
menu. Repeat this procedure if more than one hard drive has a DriveLock password.
f.If an Automatic DriveLock password is set, select the Security menu, scroll down to 
Automatic DriveLock, then select the desired hard drive and disable protection. Repeat this 
procedure if more than one hard drive has an Automatic DriveLock password.
g.Select the File menu, then Reset BIOS Security to factory default. Click yes at the warning 
message.
h.Select the File menu, then Save Changes and Exit.
23 
						

							i.Reboot the system. If the system has a Trusted Platform Module and/or fingerprint sensor, 
one or two prompts will appear: one to clear the TPM and the other to reset fingerprint 
sensor. Press 
F1 to accept or F2 to reject.
If the HP notebook model number ends in a ‘p’ or ‘w’ and includes Intel Centrino with 
VProTM, reboot the PC and enter BIOS Setup by pressing 
F10 when prompted. Select 
System Configuration, then AMT Options. Then select Un-configure AMT on next boot. 
Select 
Save, then Yes. Select the File menu, and then select Save Changes and Exit. 
Reboot the system and confirm that you want to un-configure AMT.
j.If the optional Intel Anti-Theft Technology (AT) was activated, contact the provider to 
deactivate it.
k.If the optional Absolute® Software Computrace® management and tracking service was 
activated on the notebook PC, contact the provider to deactivate it.
l.Remove all power and system batteries for at least 24 hours.
2.Remove and retain the storage drive or clear the contents of the drive.
a.Hard Disk Drive (HDD)
Clear the HDD contents by using the HP Disk Sanitizer® utility or a third party application 
that, ideally, is U.S. Department of Defense (DOD) 5220.22-M approved.
To run HP Disk Sanitizer, enter BIOS Setup by powering on the system and pressing F10 
when prompted near the bottom of the display, or press ESC to display the start up menu, 
then press 
F10. Select the Security menu and scroll down to the Utilities menu. Select Disk 
Sanitizer
 and select the desired drive. For a higher level of protection, select Optimum.
NOTE:This process will take a long time, and the amount of time varies based on the 
hard drive capacity.
b.Solid State Drive (SSD)
Clear the SSD contents by using the BIOS Setup Secure Erase command option, or by 
using a third party utility designed to erase data from an SSD. To run Secure Erase, enter 
BIOS Setup by powering on the system and pressing 
F10 when prompted near the bottom 
of the display. Select the 
Security menu and scroll down to the Utilities menu. Select 
Secure Erase and select the desired hard drive.
