4 Removal and replacement procedures
preliminary requirements

Tools required

You will need the following tools to complete the removal and replacement procedures:
Flat-bladed screwdriver
Magnetic screwdriver
Phillips P0 and Torx8 T8 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 computer, place the subassembly (and all accompanying
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
Tools required 25

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 ex cables with extreme care; these cables tear easily.

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.”
26 Chapter 4 Removal and replacement procedures preliminary requirements

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 aected 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 aects the electrostatic voltage levels generated by dierent activities.
CAUTION: A product can be degraded by as little as 700 V.
Typical electrostatic voltage levels
Relative humidity
Event 10% 40% 55%
Walking across carpet 35,000 V 15,000 V 7,500 V
Walking across vinyl oor 12,000 V 5,000 V 3,000 V
Motions of bench worker 6,000 V 800 V 400 V
Removing DIPS from plastic tube 2,000 V 700 V 400 V
Removing DIPS from vinyl tray 11,500 V 4,000 V 2,000 V
Removing DIPS from plastic foam 14,500 V 5,000 V 3,500 V
Removing bubble pack from PCB 26,500 V 20,000 V 7,000 V
Packing PCBs in foam-lined box 21,000 V 11,000 V 5,000 V
Grounding guidelines 27
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, screwdrivers, 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.
28 Chapter 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 eective, the conductive equipment 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 oor 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 oor mats.
Material Use Voltage protection level
Antistatic plastics Bags 1,500 V
Carbon-loaded plastic Floor mats 7,500 V
Metallized laminate Floor mats 5,000 V

General troubleshooting steps

A basic logic should be used when troubleshooting computer issues. This section will help you become familiar with troubleshooting methodology and eciently resolve problems. Proceed through the steps in the following table until the issue is resolved, and then move on to the next step that is relevant to the issue. For example, if you resolve a memory issue using the HP PC Diagnostics (UEFI) tool in step 6, you can then move on to step 10 to reseat the memory into its memory slot.
NOTE: General troubleshooting steps do not have to be followed in a specic order.

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.

Failure classication
Failure classication is a breakdown of dierent types of failures and symptoms that could occur during the boot-up sequence. Table 3 and table 4 represent the failure classication for common notebook failures.
Conrm that power lights are on fan is spinning.

functional. When POST is complete, the HP logo displays briey 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.
System boots to operating system, and Windows logo screen appears..
Common issues: hangs (lock up/freezes), blue screen, video distorted, driver conict, slow performance, display issue (dead pixel), I/O issue (no speaker sound), wireless/audio unavailable, noise.
See Analyze the issue on page 82 table below for detailed troubleshooting information).
Table 3 categorizes failures by the boot-up sequence.
General troubleshooting steps 79
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 identied 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
7. Mechanical
A single symptom can be listed under dierent 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 conict in Performance (4), but it can also be caused by a defective storage device 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 classication by boot-up sequence
on page 80 and Table 7-4 Failure classication by hardware devices and mechanical on page 81). 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 oered on certain
hardware congurations; therefore, a Bluetooth issue can be classied 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.
Conrm that power sources are good, such as wall power type/adapter (110V/220V ac), power strip. Test with a veried working AC outlet.
Check for compatibility issues between the computer and third-party devices, peripherals, noncertied 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 steps 81
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 specic 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 qualication 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 conict 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.
82 Chapter 7 Troubleshooting guide
6. HP Hardware Diagnostics and Tools
HP oers dierent 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 Unied 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 storage devices 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 at http://www8.hp.com/us/en/
campaigns/hpsupportassistant/pc-diags.html?jumpid=va_r602_us/en/any/pps/pl_ot_ob_ds_pd/ HP_PC_Hardware_Diagnostics_cc/dt 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.

HP BIOS Conguration Utility (BCU)
HP BCU is a free utility that captures the BIOS settings and their values. This tool provides a text le of the computer’s BIOS conguration. This can help identify any settings that may be contributing to an issue.
In some cases, it may help to compare this BIOS text le to the default settings of the computer.
For more information, see the HP BIOS Conguration Utility (BCU) User guide at http://ftp.hp.com/pub/caps-
softpaq/cmit/whitepapers/BIOS_Conguration_Utility_User_Guide.pdf.
NOTE: HP recommends that you reset BIOS before trying BCU. Resetting the BIOS is always available and
relatively quick to try, whereas BCU takes extra time and eort.
HP Image Diagnostic Tool
Available to HP Authorized Support Partners (ASPs) and users from the HP public ftp site at
ftp://ftp.hp.com/pub/idr/ImageDiags/, this tool collects information about the current state of the computer,
including product serial number, platform and BIOS information, and information about user-installed software and hardware components. HP encourages you to review the report before sending it to support. The report may assist you with diagnostics and solutions to problems you encounter.
HP Thermal Monitor
NOTE: Available only to authorized service providers/technicians.
Available only for HP internal use, HP Thermal Monitor can be used to stress the processor and GPU and monitor the temperature values of various components in the system. The components that are currently monitored include the processor, GPU, ACPI thermal zones, storage device, and battery. The tool reads the temperatures of the components, logs the data, and helps to determine whether the computer would overheat in the event of thermal shutdown, fan spinning loud, etc.

7. Status lights, blinking light codes, troubleshooting lights, and POST error messages
Carefully observe any behavior the computer may be exhibiting: status lights, blinking lights, and POST error messages during boot. It is important to understand what these indicators mean.
Status lights
See the chapter titled “External Component Identication” for light locations. The following table describes basic lights on the computer.
Component Description
Power button When the computer is o, press the button to turn on the computer.
When the computer is on, press the button briey to initiate Sleep (Windows) or Suspend (Linux).
When the computer is in the Sleep state, press the button briey to exit Sleep (Windows) or Suspend (Linux).
When the computer is in Hibernation, press the button briey to exit Hibernation.
CAUTION: Pressing and holding down the power button results in the loss of unsaved
information.
If the computer has stopped responding and operating system shutdown procedures are ineective, press and hold the power button.
Front power light On: The computer is on.
Blinking: The computer is in the Sleep state.
O: The computer is o.
Battery light White: The computer is connected to external power and the battery is charged from 90 to
99 percent.
Amber: The computer is connected to external power and the battery is charged from 0 to 90 percent.
Blinking amber: A battery that is the only available power source has reached a low battery level. When the battery reaches a critical battery level, the battery light begins blinking rapidly. By default, the critical battery level is dened in Power Options as 5%.
O: The battery is fully charged.
Front storage device light Blinking white: The storage device is being accessed.
Amber: HP 3D DriveGuard has temporarily parked the storage device.
Rear AC adapter light White: The computer is connected to external power.
O: The computer is not connected to external power.
General troubleshooting steps 87
Interpreting system validation diagnostic front panel LEDs and audible codes
During the system validation phase that occurs at system startup, the BIOS validates the functionality of the following subsystems and conditions:
AC adapter
System board power
Processor failure
BIOS corruption
Memory failure
Graphics failure
System board failure
BIOS authentication failure
If an error is detected, specic patterns of long and short blinks, accompanied by long and short beeps (where applicable) are used to identify the error. These patterns will make up a two part code:
Major – the category of the error
Minor – the specic error within the category
NOTE: Single beep/blink codes are not used.
Number of long beeps/blinks Error category
1 Not used
2 BIOS
3 Hardware
4 Thermal
5 System board
Patterns of blink/beep codes are determined by using the following parameters:
1 second pause occurs after the last major blink.
2 second pause occurs after the last minor blink.
Beep error code sequences occur for the rst 5 iterations of the pattern and then stop.
Blink error code sequences continue until the computer is unplugged or the power button is pressed.
NOTE: Not all diagnostic lights and audible codes are available on all models.
The red LED blinks to represent the major error category (long blinks). The white LED blinks to represent the minor error category (short blinks). For example, ‘2.3’ indicates 2 long red blinks and 3 short white blinks to communicate the processor is not detected. CAP/NUM Blink = 2 indicates CAP/NUM will blink 2 cycles, each cycle has one 2.3 sequence.
