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 ex cables with extreme care; these cables tear
easily.
See Cable management on page 147 and Connector types on page 148 for additional information about
removing and replacing cables.
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
o 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 one 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 elds, 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 nger 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 aected 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.
28Chapter 4 Removal and replacement procedures preliminary requirements
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 aects the electrostatic voltage levels generated by
dierent activities.
CAUTION: A product can be degraded by as little as 700 V.

Grounding guidelines29
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 nonconductive 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 eld service tools, such as cutters, screw drivers, and vacuums.
●
When xtures must directly contact dissipative surfaces, use xtures made only of static-safe materials.
●
Keep the work area free of nonconductive materials, such as ordinary plastic assembly aids and plastic
foam.
●
Handle ESD-sensitive components, parts, and assemblies by the case or PCM laminate. Handle these
items only at static-free workstations.
●
Avoid contact with pins, leads, or circuitry.
●
Turn o power and input signals before inserting or removing connectors or test equipment.
30Chapter 4 Removal and replacement procedures preliminary requirements
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 exible 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 oor 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
oors or dissipative oor mats, use foot straps on both feet with a minimum of one megohm resistance
between the operator and ground. To be
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 oor mats with hard ties to the ground
eective, the conductive equipment must be worn in contact
●
Field service kits

Identify the issue
1. Understand the issue
It is important to understand the issue that occurred, including related symptoms. It helps to understand the
basic computer boot-up sequence as well as the failure itself. The boot-up sequence and associated failures
are described below.
Boot up sequence
The computer performs several steps after you press the power button or restart the computer.
It is important to understand where in the boot-up sequence the symptoms occur. The following table lists
the phases of the boot-up sequence and explains the symptoms that may occur in each phase. For example, a
blue screen error (BSOD) often occurs during the performance phase.
Table 7-2 Boot-up sequence
Power-onAfter power button is pressed, the computer boots after all internal power rails (i.e., 5V, 3.3V) are stable.
POST (UEFI/BIOS)Power-On Self-Test (POST) veries that hardware components (processor, hard drive, memory, etc.) are
Conrm that power lights are on fan is spinning.
Next step: If the computer experiences a power-on issue, see “Verify Power Good (Troubleshooting) lights” in
No Power on page 94.
Common issues: all lights are o; troubleshooting lights are on; does not boot; video is absent.
functional. When POST is complete, the HP logo displays briey and then disappears.
If there are errors, the computer may exhibit blinking lights and POST error messages
Common issues: lights blink, error message appears, hangs.
Performance
(operating system)
Failure classication
Failure classication is a breakdown of dierent types of failures and symptoms that could occur during the
boot-up sequence. Table 3 and table 4 represent the failure classication for common notebook failures.
Table 3 categorizes failures by the boot-up sequence.
1.Power-on: Common issues are No Power, Recycle/Reboot, etc.
2.POST: Common issues are No Boot (have power), Light Flash or Diagnostics Error.
3.Performance: Common issues are Intermittent Loss of Power, Blue Screen, Hang, etc. In many cases,
issues may be identied and associated with a particular hardware (i.e., display, storage).
Table 4 categorizes failures by hardware.
4.Display
5.I/O devices (Input/Output)
6.Storage
System boots to operating system, and Windows logo screen appears.
Common issues: hangs (lock up/freezes), blue screen, video distorted, driver conict, slow performance,
display issue (dead pixel), I/O issue (no speaker sound), wireless/audio unavailable, noise.
See Analyze the issue on page 80 table below for detailed troubleshooting information).
7.Mechanical
General troubleshooting steps77
A single symptom can be listed under dierent groups. For example, No Video can belong to (1) Power-on or
(4) Display; but Flickering when powered should be listed in (4) Display. Or, in another example, a blue screen
can be caused by a driver conict in Performance (4), but it can also be caused by a defective hard drive under
(6) Storage. Therefore, failures that share similar symptoms are noted.
If possible, make a record of the failure symptom, the phase of the boot-up sequence where the failure
occurs, and the most likely location in the failure tree (Table 7-3 Failure classication by boot-up sequence
on page 78 and Table 7-4 Failure classication by hardware devices and mechanical on page 79). This will
help isolate the issue and indicate the next steps. For example, when the computer is running the operating
system, it may experience an issue with (4) Display, (5) I/O devices (keyboard, wireless, and so on), (6)
Storage, or (7) Mechanical components (stuck buttons, thermal shutdown, and so on).
NOTE: “Uncategorized” is used if an issue found is not listed. For example, Bluetooth is oered on certain
hardware congurations; therefore, a Bluetooth issue can be classied under “I/O Device” if needed.

2. Examine the environment
It is important to examine the computer’s environment. If you can quickly identify the cause of the issue,
fewer resolution steps may be needed. Perform the following environment inspections:
●
Check all cables and connections to be sure that there are no loose connections.
●
Conrm that power sources are good, such as wall power type/adapter (110V/220V ac), power strip. Test
with a veried working AC outlet.
●
Check for compatibility issues between the computer and third-party devices, peripherals, noncertied
devices, incompatible hardware (i.e., Mac OS device). Incompatibility can result in blue screen errors,
improper operation, and so on.
●
Isolate the computer from sources of electromagnetic interference (EMI), such as cell phones, 2-way
radios, oor mats, fans (and other electronic motors). EMI may contribute to a display freeze issue or
lock-up.
General troubleshooting steps79
3. Perform a visual inspection of hardware
It is important to do a visual inspection of the hardware itself. Perform physical inspection of the computer:
●
Look for abnormalities such as a cracked display, dented battery, broken latches for battery bay,
keyboard key caps popped out, dust over connectors, liquid spill over keyboard, etc.
●
Look for signs of drop, movement, or vibration that may cause internal and external loose connections.
4. Update BIOS and drivers
IMPORTANT: Whenever possible, update to the latest BIOS, rmware, and drivers before troubleshooting.
Note that some customer company policies prohibit updates. Check your company policy before taking action.
The updates may include xes for your computer issues, and they may also enhance system performance. HP
continually improves the update process to make it easier. The BIOS update can be done locally through a
manual process, through an automatic installation, or through a remote installation on multiple units.
Manually updating BIOS and drivers
●
See the Computer Setup chapters to manually update BIOS and drivers.
●
Refer to specic BIOS update installation instructions that accompany the download.
Remotely deploying BIOS and drivers
Instead of manually searching for and downloading each SoftPaq, users and IT personnel can use two tools to
identify and download all appropriate SoftPaqs for the selected HP models.
●
HP SoftPaq Download Manager (SDM) is a software tool designed to streamline the download,
extraction, and installation process of SoftPaqs, including BIOS and drivers.
●
HP System Software Manager (SSM) is a software tool designed to simplify the deployment of SoftPaqs
to HP computers.
Analyze the issue
5. Remove or uninstall recently added hardware, software
HP has designed this computer and validated it using a full-range hardware and software qualication matrix.
If an issue appears to have started recently, it may be related to the recent addition of hardware or software.
A good method to determine the root cause is to remove recently added components or uninstall applications
one at a time and restart the computer when necessary.
IMPORTANT: After you have completed the process of uninstalling hardware or software and are ready to
reinstall, when installing a new device be sure that it is seated properly and all cables are correctly connected.
After installing the device, restart the computer and make sure the new device is powered on. In addition, if
the new device is a root cause of a problem, it could cause a conict in drivers or incompatibility issues with
other programs installed. For any new hardware you have added, be sure to install the latest drivers available
from the device vendor website.
80Chapter 7 Troubleshooting guide
6. HP Hardware Diagnostics and Tools
HP oersdierent diagnostics and tools to diagnose hardware failure. This section describes how to use
some of these tools. Make sure to check for the latest versions before use.
HP PC Hardware Diagnostics (UEFI)
HP PC Hardware Diagnostics is a Unied Extensible Firmware Interface (UEFI) that allows you to run diagnostic
tests to determine whether the computer hardware is functioning properly. The HP PC Hardware Diagnostics
(UEFI) tool is built within BIOS (basic memory and hard drive diagnostics only), or within new hard drives
themselves. These drives contain more advanced versions of the diagnostic tool than the BIOS-based version.
In addition, for HP authorized service partners and IT professionals who need to support a mixed environment
of older and newer HP/Compaq PCs, the HP PC Diagnostics 3-in-1 USB Key is a diagnostic tool that supports a
wide range of HP Desktop and Notebook computers.
The tool runs outside the operating system so that it can isolate hardware failures from issues that are
caused by the operating system or other software components. In reality, many problems can be determined
using this tool if the issue is a defective part or a loose connection (i.e., reseating keyboard cable after the
tool reports a keyboard error).
The tool has three major functions:
●
System Tests - Check the computer’s hardware to assure everything is functioning properly. If your
system won’t boot into Windows, try the Quick System Test. For more comprehensive testing, use the
Extensive System Test option. If the System Test did not detect a hardware problem, continue with the
Component Tests.
●
Component Tests – Focus on selected hardware components in your computer.
●
Firmware Management – Update your computer’s BIOS to the latest version (available separately) or roll
back to a previous version.
To start HP PC Hardware Diagnostics (UEFI):
1.Turn on or restart the computer, quickly press the esc button on the computer, and then press F2. The
BIOS searches three places for the diagnostic tools, in the following order:
a.Connected USB drive
b.Hard drive
c.BIOS
General troubleshooting steps81
2.When the diagnostic tool opens, use the keyboard arrow keys to select the type of diagnostic test you
want to run, and then follow the on-screen instructions.
