10 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
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 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
Enter
to return to the prior menu.
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.
