HP EliteBook 850 G4 User Manual

14 Statement of memory volatility
The purpose of this chapter is to provide general information regarding nonvolatile memory in HP Business
PCs. This chapter also provides general instructions for restoring nonvolatile memory that can contain
personal data after the system has been powered o 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
conguration. Intel-
based and AMD-based system boards contain nonvolatile memory subcomponents as originally shipped from
HP, assuming that no subsequent modications 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 nite 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.
NOTE: If your tablet has a keyboard base, connect to the keyboard base before beginning steps in this
chapter.
Current BIOS steps
1. Follow steps (a) through (l) below to restore the nonvolatile memory that can contain personal data.
Restoring or reprogramming nonvolatile memory that does not store personal data is neither necessary
nor recommended.
a. Turn on or restart the computer, and then press esc while the “Press the ESC key for Startup Menu”
message is displayed at the bottom of the screen.
IMPORTANT: If the Main menu displays Restore Defaults instead of Apply Factory Defaults and
Exit, go to Legacy BIOS Steps on page 175.
NOTE: If the system has a BIOS administrator password, enter the password at the prompt.
b. Select Main, select Apply Factory Defaults and Exit, and then select Yes to load defaults.
The computer will reboot.
c. During the reboot, press esc while the “Press the ESC key for Startup Menu” message is displayed
at the bottom of the screen.
NOTE: If the system has a BIOS administrator password, enter the password at the prompt.
d. Select the Security menu, select Restore Security Settings to Factory Defaults, and then select
Yes to restore security level defaults.
The computer will reboot.
e. During the reboot, press esc while the “Press the ESC key for Startup Menu” message is displayed
at the bottom of the screen.
NOTE: If the system has a BIOS administrator password, enter the password at the prompt.
f. 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 Asset Tracking Number. Clear the tag, and then make the
selection to return to the prior menu.
