preliminary requirements 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 and connectors IMPORTANT: 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. 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. Electrostatic discharge information A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device exposed to electrostatic discharge (ESD) might not appear to be affected at all and can work perfectly throughout a normal cycle. The device might function normally for a while, but it has been degraded in the internal layers, reducing its life expectancy. Networks built into many integrated circuits provide some protection, but in many cases, the discharge contains enough power to alter device parameters or melt silicon junctions. 28 Chapter 4 Removal and replacement procedures preliminary requirements IMPORTANT: To prevent damage to the device 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. Generating static electricity Note the following: Different activities generate different amounts of static electricity. Static electricity increases as humidity decreases. Table 4-1 Static electricity occurrence based on activity and humidity Relative humidity Event 55% 40% Walking across carpet Walking across vinyl floor Motions of bench worker Removing DIPs (dual in-line packages) from plastic tube 7,500 V 3,000 V 400 V 400 V 15,000 V 5,000 V 800 V 700 V Removing DIPs from vinyl tray Removing DIPs from polystyrene foam Removing bubble pack from PCB (printed circuit board) Packing PCBs in foam-lined box 2,000 V 3,500 V 7,000 V 5,000 V 4,000 V 5,000 V 20,000 V 11,000 V Multiple electric components can be packaged together in plastic tubes, trays, or polystyrene foam. 10% 35,000 V 12,000 V 6,000 V 2,000 V 11,500 V 14,500 V 26,500 V 21,000 V NOTE: As little as 700 V can degrade a product. Preventing electrostatic damage to equipment Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of sensitivity. The following packaging and grounding precautions are necessary to prevent static electricity damage to electronic components. To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes. Protect all electrostatic parts and assemblies with conductive or approved containers or packaging. Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations. Place items on a grounded surface before removing them from their container. Always be properly grounded when touching a sensitive component or assembly. Electrostatic discharge information 29 Avoid contact with pins, leads, or circuitry. Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive foam. Personal grounding methods and equipment Use the following equipment to prevent static electricity damage to electronic components: Wrist straps are flexible straps with a maximum of 1 M ±10% resistance in the ground cords. To provide proper ground, a strap must be worn snug against bare skin. The ground cord must be connected and fit snugly into the banana plug connector on the grounding mat or workstation. Heel straps/Toe straps/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 them on both feet with a maximum of 1 M ±10% resistance between the operator and ground. Table 4-2 Static shielding protection levels Static shielding protection levels Method Antistatic plastic Carbon-loaded plastic Metallized laminate Voltage 1,500 7,500 15,000 Grounding the work area To prevent static damage at the work area, use the following precautions: Cover the work surface with approved static-dissipative material. Provide a wrist strap connected to the work surface and properly grounded tools and equipment. Use static-dissipative mats, foot straps, or air ionizers to give added protection. Handle electrostatic sensitive components, parts, and assemblies by the case or PCB laminate. Handle them only at static-free work areas. Turn off power and input signals before inserting and removing connectors or test equipment. Use fixtures made of static-safe materials when fixtures must directly contact dissipative surfaces. Keep work area free of nonconductive materials such as ordinary plastic assembly aids and polystyrene foam. Use field service tools, such as cutters, screwdrivers, and vacuums, that are conductive. Recommended materials and equipment HP recommends the following materials and equipment to prevent static electricity: Antistatic tape Antistatic smocks, aprons, or sleeve protectors Conductive bins and other assembly or soldering aids Conductive foam Conductive tabletop workstations with ground cord of 1 M ±10% resistance 30 Chapter 4 Removal and replacement procedures preliminary requirements Static-dissipative table or floor mats with hard tie to ground Field service kits Static awareness labels Wrist straps and footwear straps providing 1 M ±10% resistance Material handling packages Conductive plastic bags Conductive plastic tubes Conductive tote boxes Opaque shielding bags Transparent metallized shielding bags Transparent shielding tubes 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.

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. Current BIOS steps 1.

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. Questions and answers 87 4. What kind of configuration data is stored on the DIMM Serial Presence Detect (SPD) memory module? How would this data be written? 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 computer. Third-party tools do exist that can write to the EEPROM when the memory module is not installed in a computer. Various third-party tools are available to read SPD memory. 5. What is meant by "Restore the nonvolatile memory found in Intel-based system boards"? This message relates to clearing the Real Time Clock (RTC) CMOS memory that contains computer configuration data. 6. How can the BIOS security be reset to factory defaults and data erased? IMPORTANT: Resetting results in the loss of information. These steps do not reset 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 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. Using HP Sure Start (select models only) Select computer models are configured with HP Sure Start, a technology that continuously monitors your computer's BIOS for attacks or corruption. If the BIOS becomes corrupted or is attacked, HP Sure Start restores the BIOS to its previously safe state, without user intervention. Those select computer models ship with HP Sure Start configured and enabled. HP Sure Start is configured and already enabled so that most users can use the HP Sure Start default configuration. The default configuration can be customized by advanced users. To access the latest documentation on HP Sure Start, go to http://www.hp.com/support.
