Statement of memory volatility
The purpose of this appendix is to provide general information regarding nonvolatile memory in HP Business
PCs. This appendix also provides 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 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 PC system, personal data
can remain on volatile system memory (DIMMs) for a finite period of time and will also remain in nonvolatile
memory. Use the steps below to remove personal data from the PC, including the nonvolatile memory found in
Intel-based and AMD-based system boards.
