12 Statement of memory volatility
The purpose of this chapter is to provide general information regarding nonvolatile memory in HP Business
computers. This chapter 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 computer 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 computer 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 computer, including the
nonvolatile memory found in Intel-based and AMD-based system boards.
NOTE:
If your tablet has a keyboard base, connect to the keyboard base before beginning steps in this
chapter.
