Removal and replacement procedures
preliminary requirements
4
Use this information to properly prepare to disassemble and reassemble the computer.
Tools required
You need the following tools to complete the removal and replacement procedures:
● Tweezers
● Nonconductive, nonmarking pry tool
● Magnetic Phillips P1 screwdriver
Service considerations
The following sections include some of the considerations that you must keep in mind during
disassembly and assembly procedures.
NOTE: As you remove each subassembly from the computer, place the subassembly and all
accompanying screws away from the work area to prevent damage.
Plastic parts
Using excessive force during disassembly and reassembly can damage plastic parts.
Cables and connectors
Handle cables with extreme care to avoid damage.
IMPORTANT: When servicing the computer, be sure that cables are placed in their proper locations
during the reassembly process. Improper cable placement can damage the computer.
Apply only the tension required to unseat or seat the cables during removal and insertion. Handle cables
by the connector whenever possible. In all cases, avoid bending, twisting, or tearing cables. Be sure that
cables are routed so that they cannot be caught or snagged as you remove or replace parts. Handle flex
cables with extreme care; these cables tear easily.
Drive handling
Note the following guidelines when handling drives.
IMPORTANT: Drives are fragile components. Handle them with care. To prevent damage to the
computer, damage to a drive, or loss of information, observe these precautions:
● Before removing or inserting a hard drive, shut down the computer. If you are unsure whether the
computer is off or in Hibernation or Sleep mode, turn the computer on, and then shut it down
through the operating system.

● Before handling a drive, be sure that you are discharged of static electricity. While handling a drive,
avoid touching the connector.
● Before removing an optical drive, be sure that a disc is not in the drive, and be sure that the optical
drive tray is closed.
● Handle drives on surfaces covered with at least 2.54 cm (1 inch) of shock-proof foam.
● Avoid dropping drives from any height onto any surface.
● After removing a hard drive or an optical drive, place it in a static-proof bag.
● Avoid exposing an internal hard drive to products that have magnetic fields, such as monitors or
speakers.

Electrostatic discharge information
A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive
devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic
device exposed to electrostatic discharge (ESD) might not appear to be affected at all and can work
perfectly throughout a normal cycle. The device might function normally for a while, but it has been
degraded in the internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases, the discharge
contains enough power to alter device parameters or melt silicon junctions.
IMPORTANT: To prevent damage to the device when you remove or install internal components,
observe these precautions:
● Keep components in their electrostatic-safe containers until you are ready to install them.
● Before touching an electronic component, discharge static electricity by using the guidelines
described in Personal grounding methods and equipment on page 19.
● Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.
● If you remove a component, place it in an electrostatic-safe container.
Generating static electricity
Follow these static electricity guidelines:
● Different activities generate different amounts of static electricity.
● Static electricity increases as humidity decreases.

Preventing electrostatic damage to equipment
Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree
of sensitivity.
The following packaging and grounding precautions are necessary to prevent static electricity damage
to electronic components:
● To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes.
● Protect all electrostatic parts and assemblies with conductive or approved containers or packaging.
● Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
● Place items on a grounded surface before removing them from their container.
● Always be properly grounded when touching a sensitive component or assembly.
● Avoid contact with pins, leads, or circuitry.
● Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive
foam.
Personal grounding methods and equipment
Using certain equipment can prevent static electricity damage to electronic components.
● Wrist straps are flexible straps with a maximum of 1 MΩ ±10% resistance in the ground cords. To
provide proper ground, wear a strap snug against bare skin. Verify that the ground cord is connected
and fits snugly into the banana plug connector on the grounding mat or workstation.
● You can use heel straps, toe straps, and boot straps at standing workstations. These straps are
compatible with most types of shoes or boots. On conductive floors or dissipative floor mats, use
them on both feet with a maximum of 1 MΩ ±10% resistance between the operator and ground.

Questions and answers
Use this section to answer your questions about nonvolatile memory.
1. How can the BIOS settings be restored (returned to factory settings)?
IMPORTANT: The restore defaults feature does not securely erase any information on your hard
drive. See question and answer 6 for steps to securely erase information.
The restore defaults feature does not reset the Custom Secure Boot keys. See question and
answer 7 for information about resetting the keys.
a. Turn on or restart the computer, and then quickly press esc.
b. Select Main, and then select Apply Factory Defaults and Exit.
c. Follow the on-screen instructions.
d. Select Main, select Save Changes and Exit, and then follow the on-screen instructions.
2. What is a UEFI BIOS, and how is it different from a legacy BIOS?
The Unified Extensible Firmware Interface (UEFI) BIOS is an industry-standard software interface
between the platform firmware and an operating system (OS). It replaces the older BIOS
architecture but supports much of the legacy BIOS functionality.
Like the legacy BIOS, the UEFI BIOS provides an interface to display the system information and
configuration settings and to change the configuration of your computer before an OS is loaded.
BIOS provides a secure runtime environment that supports a GUI. In this environment, you can use
either a pointing device (touch screen, touchpad, pointing stick, or USB mouse) or the keyboard to
navigate and make menu and configuration selections. The UEFI BIOS also contains basic system
diagnostics.
The UEFI BIOS provides functionality beyond that of the legacy BIOS. In addition, the UEFI BIOS
works to initialize the computer’s hardware before loading and executing the OS; the runtime
environment allows the loading and execution of software programs from storage devices to
provide more functionality, such as advanced hardware diagnostics (with the ability to display more
detailed system information) and advanced firmware management and recovery software.
HP has provided options in Computer Setup BIOS to allow you to run in legacy BIOS, if required by
the operating system. Examples of this requirement would be if you upgrade or downgrade the OS.
3. Where is the UEFI BIOS located?
The UEFI BIOS is located on a flash memory chip. You must use a utility to write to the chip.
62
Chapter 8 Statement of memory volatility
4. What kind of configuration data is stored on the DIMM Serial Presence Detect (SPD) memory
module? How would this data be written?
The DIMM SPD memory contains information about the memory module, such as size, serial
number, data width, speed and timing, voltage, and thermal information. This information is written
by the module manufacturer and stored on an EEPROM. You cannot write to this EEPROM when the
memory module is installed in a computer. Third-party tools do exist that can write to the EEPROM
when the memory module is not installed in a computer. Various third-party tools are available to
read SPD memory.
5. What is meant by “Restore the nonvolatile memory found in Intel-based system boards”?
This message relates to clearing the Real Time Clock (RTC) CMOS memory that contains computer
configuration data.
6. How can the BIOS security be reset to factory defaults and erase the data?
IMPORTANT: Resetting results in the loss of information.
These steps do not reset Custom Secure Boot Keys. See question and answer 7 for information
about resetting the keys.
a. Turn on or restart the computer, and then quickly press esc.
b. Select Main, and then select Reset Security to Factory Defaults.
c. Follow the on-screen instructions.
d. Select Main, select Save Changes and Exit, and then follow the on-screen instructions.
7. How can the Custom Secure Boot Keys be reset?
Secure Boot is a feature to ensure that only authenticated code can start on a platform. If you
enabled Secure Boot and created Custom Secure Boot Keys, disabling Secure Boot does not clear
the keys. You must also select to clear the Custom Secure Boot Keys. Use the same Secure Boot
access procedure that you used to create the Custom Secure Boot Keys, but select to clear or
delete all Secure Boot Keys.
a. Turn on or restart the computer, and then quickly press esc.
b. Select the Security menu, select Secure Boot Configuration, and then follow the on-screen
instructions.
c. At the Secure Boot Configuration window, select Secure Boot, select Clear Secure Boot Keys,
and then follow the on-screen instructions to continue.
