15 Statement 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 o 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 conguration.
Intel-based and AMD-based system boards contain nonvolatile memory subcomponents as originally shipped
from HP assuming that no subsequent modications 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 nite 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 & 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 reprogramming 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 Conguration 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 conrm 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.
i. Reboot the system. If the system has a Trusted Platform Module (TPM) and/or ngerprint 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 Conguration,
