4 Removal and replacement procedurespreliminary requirements
Tools required
You will need the following tools to complete the removal and replacement procedures:
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 parts. Apply pressure only at the points designated in the maintenance instructions.
Tools required 27
#### 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.
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 storage device, 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 storage device, an optical drive, or a diskette drive, place it in a static-proof bag. Avoid exposing an internal storage device 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.

General troubleshooting steps
A basic logic should be used when troubleshooting computer issues. This section will help you become familiar with troubleshooting methodology and efficiently 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 specific order if an issue does not apply.

####### Resources 81
######## Table 7-1 Troubleshooting methodology and general troubleshooting steps (continued)
#### 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-on After power button is pressed, the computer boots after all internal power rails (i.e., 5V, 3.3V) are stable. Confirm 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 100. Common issues: all lights are off; troubleshooting lights are on; does not boot; video is absent.
POST (UEFI/BIOS) Power-On Self-Test (POST) verifies that hardware components (processor, storage device, memory, etc.) are functional. When POST is complete, the HP logo displays briefly 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)
System boots to operating system, and Windows logo screen appears.. Common issues: hangs (lock up/freezes), blue screen, video distorted, driver conflict, slow performance, display issue (dead pixel), I/O issue (no speaker sound), wireless/audio unavailable, noise. See Analyze the issue on page 85 table below for detailed troubleshooting information).
###### Failure classification
Failure classification is a breakdown of different types of failures and symptoms that could occur during the boot-up sequence. Table 3 and table 4 represent the failure classification for common notebook failures.
Table 3 categorizes failures by the boot-up sequence.
A single symptom can be listed under different 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 conflict 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 classification by boot-up sequence on page 83 and Table 7-4 Failure classification by hardware devices and mechanical on page 84). 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 offered on certain hardware configurations; therefore, a Bluetooth issue can be classified under “I/O Device” if needed.

b,c,d similar symptoms
##### 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:
IMPORTANT: Whenever possible, update to the latest BIOS, firmware, and drivers before troubleshooting. Note that some customer company policies prohibit updates. Check your company policy before taking action. The updates may include fixes 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
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.
Analyze the issue
| | |---|
HP has designed this computer and validated it using a full-range hardware and software qualification 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 conflict 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.
##### 6. HP Hardware Diagnostics and Tools
HP offers different 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 Unified 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 storage device 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 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:
To start HP PC Hardware Diagnostics (UEFI):


| | |---|
| | |---|
NOTE: Users should utilize this tool, especially when the computer cannot boot to Windows. NOTE: If a component fails a test, write down the information so it is available when contacting support. The information is also available in Test Logs on the Main Menu. For more information, see the chapter titled “Using HP PC Hardware Diagnostics (UEFI).”
###### HP Support Assistant (HPSA)
HP Support Assistant (HPSA) helps you maintain peak performance and resolve problems through automatic updates, built-in diagnostics, and a variety of assistance options. HPSA is preinstalled on every new HP PC with Windows 7, Windows 8, or Windows 10. HP is continually improving this tool. Please verify the latest version is installed to receive the most benefit. For more information, see HP Support Assistant.
| | |---|
NOTE: HPSA can be used only if the computer boots into Windows. If the computer does not boot into Windows, use HP PC Hardware Diagnostics (UEFI) instead. HPSA also integrates diagnostics and tools that help resolve issues. See example screen shots as follows.



###### HP BIOS Configuration Utility (BCU)
HP BCU is a free utility that captures the BIOS settings and their values. This tool provides a text file of the computer’s BIOS configuration. This can help identify any settings that may be contributing to an issue.
| | |---|
In some cases, it may help to compare this BIOS text file to the default settings of the computer. For more information, see the HP BIOS Configuration Utility (BCU) User guide. 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 effort.
###### HP Image Diagnostic Tool
Available to HP Authorized Support Partners (ASPs) and users from the HP public ftp site, 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.
###### Non HP diagnostics tools
Windows-to-Go USB
Windows-To-Go USB is a Microsoft-based tool for Enterprise editions of Windows that can help in troubleshooting. You can find a process online about how to create a live Windows USB drive. For more information, see Windows To Go: Feature Overview.
Intel Processor Diagnostic Tool
Determine what processor is in your computer and verify the processor operating frequency. The tool also tests specific processor features and performs a stress test on the processor. For more information, see http://www.intel.com/support/processors/sb/CS-031726.htm?iid=subhdr+tools_procdiagtool.
##### 7. Status lights, blinking light codes, troubleshooting lights, and POST error messages

###### 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:
| | |---|
If an error is detected, specific 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:
Number of long beeps/blinks Error category
Patterns of blink/beep codes are determined by using the following parameters:
| | |---|
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.

###### Power Good (Troubleshooting) lights
HP has added troubleshooting power lights to ZBook G3 Mobile Workstations (Studio, ZBook 15, and ZBook
17) to help troubleshoot power-on issues. The lights indicate when the system board power rails are unstable and/or the system needs a hardware reset.

These lights should be visible after removing the service door or bottom cover. Consult with support for platform-specific locations of the lights.

Troubleshooting lights diagram
####### ● Example: System board is good. Lights that turn on briefly (< 1 second) and immediately turn off indicatenormal function. In this case, system (3.3V), power good (3.3V), and system reset (3.3V) are all good and
troubleshooting lights should not be lit. However, other external lights should be lit as normal afterward.
Troubleshooting lights External lights Action Note Off On Do not replace system board No power-on issue On Off Replace board Power-on issue
(2) power good is low (0V), and troubleshooting lights will turn on. After you press the system power button, troubleshooting lights will turn on for 5 seconds and turn off. The system external lights will not light up. Follow general troubleshooting steps (i.e., remove recently added hardware, test with minimum configuration, etc.) prior to replacing the system board.

#### Resolve the issue
##### 8. Hard reset
A hard reset (or forced reset) erases all information in the computer's memory and may restore functionality. Resetting the computer forces the system to clear and reestablish the connections between the BIOS and the hardware.
Performing a hard reset might fix the following common conditions:
Before performing a hard reset, you must disconnect or remove all peripheral devices. You should start and test the computer by itself, and if the problem is not resolved, reconnect one peripheral device at a time. To resolve the startup or operational problem, run HP Support Assistant, or manually install all updated drivers from Microsoft and HP.
Before beginning, turn the computer over and look for a battery compartment door (service door). For 2015 platforms, the battery is considered removable but not accessible. See the battery section for how to remove/ unplug the battery.
To perform a hard reset on a computer with a sealed or non removable battery, use the following steps:
###### Clear CMOS
CMOS refers to the battery-powered, semiconductor chip located on computer's system board. Notebooks store low-level settings like the system time and hardware settings in CMOS. Sometimes it is necessary to clear CMOS, which requires removing and reinserting the 3V RTC battery for a short period of time (a few minutes before reinserting), in addition to removing the AC adapter and battery.
| | |---|
NOTE: Clearing the CMOS should only be performed for troubleshooting purposes. There is no reason to clear CMOS if the computer is working properly. The notebook service door must be removed to access the CMOS battery. See the RTC battery replacement section for the battery removal/replacement.
##### 9. Soft reset (Default Settings)
| | |---|
NOTE: Some company policies prohibit updates or changes. Check whether the computer has custom BIOS settings before taking action. If your computer is having issues booting, has errors during boot, is running into issues after adding hardware, or you are having other abnormal system behaviors that cannot be resolved through any other methods (i.e., hard reset), it may be necessary to reset the system BIOS to default settings. To load BIOS to default settings: Reboot the computer, and then press F10 > Main > Restore defaults. For more information, see the BIOS F10 Setup technical white paper at http://support.hp.com, enter your computer model, and then go to Manuals > White papers > HP PC BIOS F10 Setup Guide.
##### 10. Reseat cables and connections
| | |---|
NOTE: Before disassembling the computer to reseat cables and connections, always disconnect power and remove the battery or disconnect a non removable battery. Many problems are caused by improper connections or loose connections due to abnormal movement and vibration. See Cable management on page 153 and Connector types on page 154 for suggested cable management practices when removing and installing components.
You can access and reseat connections for Customer Self-Repair (CSR) parts (see the “Removal and replacement procedures for Customer Self-Repair parts” chapter for details). Examples of reseating hardware include:
For field replaceable units (FRUs), authorized service providers can try the following steps (for more information, see the ”Removal and replacement procedures for authorized service provider parts” chapter).
##### 11. Test with minimum configuration
The factory-shipped computer (hardware configuration and preinstalled operating system image) is well tested and ready for use. Therefore, using the original factory hardware configuration and/or booting to operating system safe mode often resolves issues quickly.
Essential hardware configuration NOTE: This step is to be used by authorized service providers only. HP will not honor the warranty for a system tested with the system board removed without the heat sink, fan, etc. If none of the steps above resolve the issue, start the computer with essential hardware only. The purpose is to remove as much as hardware as possible while still maintaining the computer’s ability to turn on. This essential configuration is often used to troubleshoot power-on related issues, such as no-boot, reboot, and freezing issues. The essential hardware consists of the following:
| | |---|
| | |---|
NOTE: After the service door is removed, disconnect all connections (internal keyboard, display, discrete GPU, hard drive/solid-state drive, daughterboards, etc.) to achieve the essential hardware configuration above. DO NOT disassemble the system board from its enclosure at this time.
Reverse the procedure above by reinstalling each piece of hardware removed, one piece at a time, and testing your computer after each installation. Since your computer works with only the essential hardware installed, those parts must be working properly. This means that one of the hardware components removed is causing the computer to not work properly. By installing each device back into the computer and testing each time, the failing hardware will eventually be identified.
###### Safe mode
A driver conflict often results in a blue screen error message. Therefore, booting in safe mode can resolve many issues in Windows because safe mode forces the computer to load a limited version of Windows which only contains essential files. Safe mode is useful for troubleshooting problems with programs and drivers that might not start correctly or that might prevent Windows from starting correctly.
If a problem does not reappear when you start in safe mode, eliminate the default settings and basic device drivers as possible causes. Refer to the links below for how to start your computer in safe mode:
##### 12. Test with verified working configuration (hardware and/or operating system)
One troubleshooting technique that can quickly isolate an issue is using a verified working part while testing. A good example is to use an external keyboard, mouse, or VGA monitor when you have issues with an internal keyboard, TouchPad, or display. Testing with a verified working AC adapter can identify an error caused by a faulty one. Similarly, testing with a verified working operating system can determine bad behaviors of the current operating system. See Non HP diagnostics tools on page 89 for instructions about obtaining and using a Windows-To-Go USB.
| | |---|
NOTE: In some situations, more than one item may contribute to a problem.
##### 13. Replace the system board
The system board may be replaced only by authorized service providers. This should not be considered an initial step taken to resolve an issue. Review and perform all steps discussed previously before replacing the system board. 4. Update BIOS and drivers on page 85, 7. Status lights, blinking light codes, troubleshooting lights, and POST error messages on page 90, 8. Hard reset on page 94, and 9. Soft reset (Default Settings) on page 95, and/or 10. Reseat cables and connections on page 95 can resolve many system board issues without requiring the effort of replacing unnecessary hardware. Review Table 7-1 Troubleshooting methodology and general troubleshooting steps on page 81 for appropriate troubleshooting steps.
| | |---|
IMPORTANT: System board failure is not common. Do not replace the system board until you have tried all other troubleshooting options.
| | |---|
NOTE: Determine whether a previous service case might be related to the current problem. For example, a fan detection issue may be caused by a loose connection resulting from previous service.
TIP: Without an RTC battery (3V coin-cell battery), the computer automatically reboots. This is a useful feature when the power connector cable (between external AC adapter and system board) is defective.
| | |---|
NOTE: Most of the time, effective troubleshooting can prevent a system board replacement. Items that may prevent resolution of the issue:
#### Verify solution

14 Statement of memory volatility
The purpose of this chapter is to provide general information regarding nonvolatile memory in HP Business PCs. This chapter also provides general instructions for restoring nonvolatile memory that can contain personal data after the system has been powered off and the storage device has been removed.
HP Business PC products that use Intel®-based or AMD®-based system boards contain volatile DDR memory. The amount of nonvolatile memory present in the system depends upon the system configuration. Intelbased and AMD-based system boards contain nonvolatile memory subcomponents as originally shipped from HP, assuming that no subsequent modifications have been made to the system and assuming that no applications, features, or functionality have been added to or installed on the system.
Following system shutdown and removal of all power sources from an HP Business PC system, personal data can remain on volatile system memory (DIMMs) for a finite period of time and will also remain in nonvolatile memory. Use the steps below to remove personal data from the PC, including the nonvolatile memory found in Intel-based and AMD-based system boards.
| | |---|
NOTE: If your tablet has a keyboard base, connect to the keyboard base before beginning steps in this chapter.

Questions and answers
IMPORTANT: Restore defaults does not securely erase any data on your storage device. See question and answer 6 for steps to securely erase data. Restore defaults does not reset the Custom Secure Boot keys. See question and answer 7 for information about resetting the keys.
The Unified Extensible Firmware Interface (UEFI) BIOS is an industry-standard software interface between the platform firmware and an operating system (OS). It is a replacement for 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 run-time environment that supports a Graphic User Interface (GUI). In this environment, you can use either a pointing device (Touchscreen, 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 run-time 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.
The DIMM SPD memory contains information about the memory module, such as size, serial number, data width, speed/timing, voltage, and thermal information. This information is written by the module manufacturer and stored on an EEPROM. This EEPROM cannot be written to when the memory module is installed in a PC. Third-party tools do exist that can write to the EEPROM when the memory module is not installed in a PC. Various third-party tools are available to read SPD memory.
This message relates to clearing the Real Time Clock (RTC) CMOS memory that contains PC configuration data.
