14 Statement of Volatility

The purpose of this chapter is to provide general information regarding nonvolatile 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.
1. Follow steps (a) through (j) 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
the bottom of the display, or press the
F10. If the system has a BIOS administrator password, enter the password at the prompt.
b. Select Main > Restore Defaults.
c. Select the Security menu, and then Restore Security Level 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 the select Asset Tracking Number. Press the
spacebar once to clear the tag, then press
e. If a DriveLock password is set, select the Security menu, scroll down to Hard Drive Tools
under the Utilities menu, select Hard Drive Tools, select DriveLock, then uncheck
DriveLock password on restart.
f. If an Automatic DriveLock password is set, select the Security menu, scroll down to Hard
Drive Tools under the Utilities menu, select Hard Drive Tools, scroll down to Automatic
DriveLock, then select the desired hard drive and disable protection. At the automatic drive
lock warning screen, select Yes to continue. Repeat this procedure if more than one hard
drive has an Automatic DriveLock password.
g. Select the Main menu, then Reset BIOS Security to factory default. Click yes at the
warning message.
h. Select the Main menu, then Save Changes and Exit.
ESC key to display the start up menu, then press
