10 Statement Of Volatility - HP 355 G2 Maintenance And Service Manual

10 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.
