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
       IMPORTANT:      Using excessive force during disassembly and reassembly can damage plastic parts.
       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.
                                                                                                   Tools required   27
 Drive handling
            IMPORTANT: 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 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.”
 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, screw drivers, 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 polystyrene 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 off power and input signals before inserting or removing connectors or test equipment.

10 Statement of memory volatility
          The purpose of this chapter is to provide general information regarding nonvolatile memory in HP Business
          computers. This chapter also provides general instructions for restoring nonvolatile memory that can contain
          personal data after the system has been powered off and the hard drive has been removed.
          HP Business computer 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.
          Intel-based 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 computer 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 to remove personal data from the computer, 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.
          1.   Follow steps (a) through (l) to restore the nonvolatile memory that can contain personal data. Restoring
               or reprogramming nonvolatile memory that does not store personal data is neither necessary nor
               recommended.

                     IMPORTANT: Restore defaults does not securely erase any data on your hard drive. 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.
                     a.   Turn on or restart the computer, and then press esc while the “Press the ESC key for Startup Menu”
                          message is displayed at the bottom of the screen.
                     b.   Select Main, and then select Apply Factory Defaults and Exit.
                     c.   Follow the on-screen instructions.
                     d.   Select Main, select Save Changes and Exit, and then follow the on-screen instructions.
            2.       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 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 (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 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.
            3.       Where does the UEFI BIOS reside?
                     The UEFI BIOS resides on a flash memory chip. A utility must be used to write to the chip.
                 a.   Turn on or restart the computer, and then press esc while the “Press the ESC key for Startup Menu”
                      message is displayed at the bottom of the screen.
                 b.   Select Main, and then select Reset Security to Factory Defaults.
                 c.   Follow the on-screen instructions.
                 d.   Select Main, select Save Changes and Exit, and then follow the on-screen instructions.
            7.   How can the Custom Secure Boot Keys be reset?
                 Secure Boot is a feature to ensure that only authenticated code can start on a platform. If you enabled
                 Secure Boot and created Custom Secure Boot Keys, simply disabling Secure Boot does not clear the keys.
                 You must also select to clear the Custom Secure Boot Keys. Use the same Secure Boot access procedure
                 you used to create the Custom Secure Boot Keys, but make the selection to clear or delete all Secure
                 Boot Keys.
                 a.   Turn on or restart the computer, and then press esc while the “Press the ESC key for Startup Menu”
                      message is displayed at the bottom of the screen.
                 b.   Select the Security menu, select Secure Boot Configuration, and then follow the on-screen
                      instructions.
                 c.   At the Secure Boot Configuration window, select Secure Boot, select Clear Secure Boot Keys, and
                      then follow the on-screen instructions to continue.
     The wide-range input feature of the computer permits it to operate from any line voltage from 100 to 120 V
     ac, or from 220 to 240 V ac.
     The 3-conductor power cord set included with the computer meets the requirements for use in the country or
     region where the equipment is purchased.
     Power cord sets for use in other countries or regions must meet the requirements of the country and region
     where the computer is used.
