11 Statement of memory volatility

For general information regarding nonvolatile memory in HP Business computers, and to restore nonvolatile
memory that can contain personal data after the system has been turned off and the hard drive has been
removed, use these instructions.
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, with the following assumptions:
No subsequent modifications were made to the system.
No applications, features, or functionality were 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 also remains in
nonvolatile memory. Use the following steps 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.
