4 Removal and replacement procedures preliminary requirements Tools required You will need the following tools to complete the removal and replacement procedures: ● Phillips P0 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.
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.
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.
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.
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 flexible 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.

8 Computer Setup (BIOS), TPM, and HP Sure Start Using Computer Setup Computer Setup, or Basic Input/Output System (BIOS), controls communication between all the input and output devices on the system (such as disk drives, display, keyboard, mouse, and printer). Computer Setup includes settings for the types of devices installed, the startup sequence of the computer, and the amount of system and extended memory. NOTE: Use extreme care when making changes in Computer Setup.
To return all settings in Computer Setup to the values that were set at the factory, follow these steps: 1. Start Computer Setup. See Starting Computer Setup on page 78. 2. Select Main, and then select Apply Factory Defaults and Exit. NOTE: On select products, the selections may display Restore Defaults instead of Apply Factory Defaults and Exit. 3. Follow the on-screen instructions. 4.
Downloading a BIOS update CAUTION: To reduce the risk of damage to the computer or an unsuccessful installation, download and install a BIOS update only when the computer is connected to reliable external power using the AC adapter. Do not download or install a BIOS update while the computer is running on battery power, docked in an optional docking device, or connected to an optional power source.
● 2. Turn on or restart the computer, and when the HP logo appears, press f9 to enter the Boot Device Options menu. Select a boot device, then press enter. TPM BIOS settings (select products only) IMPORTANT: Before enabling Trusted Platform Module (TPM) functionality on this system, you must ensure that your intended use of TPM complies with relevant local laws, regulations and policies, and approvals or licenses must be obtained if applicable.
9 Using 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.

You can use Windows tools to create system restore points and create backups of personal information, see Using Windows tools on page 85. ● If your computer does list the Recovery partition and the Windows partition, you can use HP Recovery Manager to create recovery media after you successfully set up the computer. HP Recovery media can be used to perform system recovery if the hard drive becomes corrupted.
Restore and recovery There are several options for recovering your system. Choose the method that best matches your situation and level of expertise: IMPORTANT: ● Windows offers several options for restoring from backup, refreshing the computer, and resetting the computer to its original state. For more information see the Get started app. ▲ ● Not all methods are available on all products. Select the Start button, and then select the Get started app.
website. Go to http://www.hp.com/support, select your country or region, and follow the on-screen instructions.

Using HP Recovery media, you can choose from one of the following recovery options: NOTE: Only the options available for your computer display when you start the recovery process.
1. If possible, back up all personal files. 2. Insert the HP Recovery media, and then restart the computer. NOTE: If the computer does not automatically restart in HP Recovery Manager, change the computer boot order. See Changing the computer boot order on page 88. 3. Follow the on-screen instructions.
Removing the HP Recovery partition (select products only) HP Recovery Manager software allows you to remove the HP Recovery partition to free up hard drive space. IMPORTANT: After you remove the HP Recovery partition, you will not be able to perform System Recovery or create HP recovery media from the HP Recovery partition. So before you remove the Recovery partition, create HP Recovery media; see Creating HP Recovery media (select products only) on page 84.

Nonvolatile Memory Type Amount (Size) Does this memory store customer data? Does this memory retain data when power is removed? What is the purpose of this memory? How is data input into this memory? How is this memory write-protected? upgrade is necessary to address a unique issue. Fingerprint reader 512 KByte flash Yes Yes Stores fingerprint templates. Fingerprint reader memory is programmed by user enrollment in HP ProtectTools Security Manager.
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 PC.
14 Recycling When a non-rechargeable or rechargeable battery has reached the end of its useful life, do not dispose of the battery in general household waste.
