Removal and replacement procedures
preliminary requirements
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 withextreme care; these cables tear easily.

Drive handling
Note the following guidelines when handling drives.

22

Chapter 4 Removal and replacement procedures preliminary requirements

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, 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.
Avoid exposing a drive to temperature extremes or liquids.
If a drive must be mailed, place the drive in a bubble pack mailer or other suitable form of protective
packaging, and label the package “FRAGILE.”

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 theinternal 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
Personal grounding methods and equipment on page 24.
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.

Multiple electric components can be packaged together in plastic tubes, trays, or polystyrene foam.

NOTE:

As little as 700 V can degrade a product.

Preventing electrostatic damage to equipment
Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree ofsensitivity. 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, a strap must be worn snug against bare skin. The ground cord must beconnected and fit snugly into the banana plug connector on the grounding mat or workstation.

●

Heel straps/Toe straps/Boot straps can be used at standing workstations and are compatible withmost types of shoes or boots. On conductive floors or dissipative floor mats, use them on both feet witha maximum of 1 MΩ ±10% resistance between the operator and ground.

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 andconfiguration settings and to change the configuration of your computer before an OS is loaded. BIOS
provides a secure runtime environment that supports a Graphic User Interface (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 toinitialize 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 theoperating 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.

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 themodule 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 thememory 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 computerconfiguration data.

6.

How can the BIOS security be reset to factory defaults and erase the data?
