4 Removal and replacement procedures
Preliminary replacement requirements
Tools required
You will need the following tools to complete the removal and replacement procedures:
●Flat-bladed screwdriver
●Magnetic screwdriver
●Phillips P0 and P1 screwdrivers
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 compute y (and all accompanyingr, place the subassembl
screws) away from the work area to prevent damage.
Plastic parts
CAUTION: Using excessive force during disassembly and reassembly can damage plastic parts. Use care
when handling the plastic parts. Apply pressure only at the points designated in the
maintenance instructions.
Cables and connectors
CAUTION: 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.
Cables must be handled with extreme care to avoid damage. 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 in such a way that they cannot be
caught or snagged by parts being removed or replaced. Handle flex cables with extreme care; these cables
tear easily.
Preliminary replacement requirements 29
Drive handling
CAUTION: Drives are fragile components that must be handled 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 a diskette drive or optical drive, be sure that a diskette or disc is not in the drive and be sure
that the optical drive tray is closed.
Handle drives on surfaces covered with at least one inch of shock-proof foam.
Avoid dropping drives from any height onto any surface.
After removing a hard drive, an optical drive, or a diskette 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.”
Grounding guidelines
Electrostatic discharge damage
Electronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structure
determine the degree of sensitivity. Networks built into many integrated circuits provide some protection,
but in many cases, ESD contains enough power to alter device parameters or melt silicon junctions.
A discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or
microcircuitry. Even if the spark is neither felt nor heard, damage may have occurred.
An electronic device exposed to ESD may not be affected at all and can work perfectly throughout a normal
cycle. Or the device may function normally for a while, then degrade in the internal layers, reducing its life
expectancy.
CAUTION: To prevent damage to the computer when you are removing or installing 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 this
section.
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.
The following table shows how humidity affects the electrostatic voltage levels generated by
different activities.
CAUTION: A product can be degraded by as little as 700 V.

Packing PCBs in foam-lined box 21,000 V 11,000 V 5,000 V
Packaging and transporting guidelines
Follow these grounding guidelines when packaging and transporting equipment:
●To avoid hand contact, transport products in static-safe tubes, bags, or boxes.
●Protect ESD-sensitive parts and assemblies with conductive or approved containers or packaging.
●Keep ESD-sensitive parts in their containers until the parts arrive at static-free workstations.
●Place items on a grounded surface before removing items from their containers.
●Always be properly grounded when touching a component or assembly.
●Store reusable ESD-sensitive parts from assemblies in protective packaging or non-conductive foam.
●Use transporters and conveyors made of antistatic belts and roller bushings. Be sure that mechanized
equipment used for moving materials is wired to ground and that proper materials are selected to avoid
static charging. When grounding is not possible, use an ionizer to dissipate electric charges.
Workstation guidelines
Follow these grounding workstation guidelines:
●Cover the workstation with approved static-shielding material.
●Use a wrist strap connected to a properly grounded work surface and use properly grounded tools and
equipment.
●Use conductive field service tools, such as cutters, screwdrivers, and vacuums.
●When fixtures must directly contact dissipative surfaces, use fixtures made only of static-
safe materials.
●Keep the work area free of nonconductive materials, such as ordinary plastic assembly aids
and Styrofoam.
●Handle ESD-sensitive components, parts, and assemblies by the case or PCM laminate. Handle these
items only at static-free workstations.
Preliminary replacement requirements 31
●Avoid contact with pins, leads, or circuitry.
●Turn off power and input signals before inserting or removing connectors or test equipment.
Equipment guidelines
Grounding equipment must include either a wrist strap or a foot strap at a grounded workstation.
●When seated, wear a wrist strap connected to a grounded system. Wrist straps are flexible straps with a
minimum of one megohm ±10% resistance in the ground cords. To provide proper ground, wear a strap
snugly against the skin at all times. On grounded mats with banana-plug connectors, use alligator clips
to connect a wrist strap.
●When standing, use foot straps and a grounded floor mat. Foot straps (heel, toe, or boot straps) can be
used at standing workstations and are compatible with most types of shoes or boots. On conductive
floors or dissipative floor mats, use foot straps on both feet with a minimum of one megohm resistance
between the operator and ground. To be effective, the conductive must be worn in contact with the
skin.
The following grounding equipment is recommended to prevent electrostatic damage:
●Antistatic tape
●Antistatic smocks, aprons, and sleeve protectors
●Conductive bins and other assembly or soldering aids
●Nonconductive foam
●Conductive tabletop workstations with ground cords of one megohm resistance
●Static-dissipative tables or floor mats with hard ties to the ground
●Field service kits
●Static awareness labels
●Material-handling packages
●Nonconductive plastic bags, tubes, or boxes
●Metal tote boxes
●Electrostatic voltage levels and protective materials
The following table lists the shielding protection provided by antistatic bags and floor mats.

Hardware Diagnostics (UEFI) in Windows 8
Setup Utility, or Basic Input/Output System (BIOS), controls communication between all the input and output
devices on the system (such as disk drives, display, keyboard, mouse, and printer). Setup Utility (BIOS)
includes settings for the types of devices installed, the startup sequence of the computer, and the amount of
system and extended memory.
Starting Setup Utility (BIOS)
To start Setup Utility (BIOS), turn on or restart the computer, quickly press esc, and then press f10.
NOTE: Use extreme care when making changes in Setup Utility (BIOS). Errors can prevent the computer
from operating properly.
Updating the BIOS
Updated versions of the BIOS may be available on the HP website.
Most BIOS updates on the HP website are packaged in compressed files called SoftPaqs.
Some download packages contain a file named Readme.txt, which contains information regarding installing
and troubleshooting the file.
Determining the BIOS version
To determine whether available BIOS updates contain later BIOS versions than those currently installed on
the computer, you need to know the version of the system BIOS currently installed.
BIOS version information (also known as ROM date and System BIOS) can be revealed by pressing fn+esc (if
you are already in Windows) or by using Setup Utility (BIOS).
1. Start Setup Utility (BIOS) (see Starting Setup Utility (BIOS) on page 73).
2. Use the arrow keys to select Main.
3. To exit Setup Utility (BIOS) without saving your changes, use the arrow keys to select Exit Exit, select
Discarding Changes, and then press enter.
4. Select Yes.
