7 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 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.
